Water Heater Buying Guide 2022 - Energy Star rating, price, fuel, rebates, etc. 

I've got a walkout basement with a southern exposure outside of Atlanta. My 80 gal rheem has replaced the basement dehumidifier AND the window AC unit I had for the summers, while also replacing the electric hot water heater. I've replaced three pieces of equipment with one, and the unit has paid for itself in about 8 months. Without any rebates at all. Your video from 10 years ago was the inspiration to switch, which we did in 2020 (didn't hurt the old tank was 17 years old...)

Great session, Omer of your best ever. Would love to see you do lots more like this with hard data and comparisons.

We had a tankless water heater for almost 20 years before installing a new one because the original manufacturer sold out and I could not find a pilot light part I needed. Great water heater that always provided almost instant hot water for as long as you wanted. After watching youtube videos about servicing the water line due to calcium or mineral buildup, I actually cut apart the water coil inside the uninstalled unit during replacement and found the lines as clean as a whistle, very surprised as we had never cleaned it!! We have a cheap whole house sediment filter installed on the water line going into the house and I suppose this filtered out any of the mineral products. Due to our experience with the first unit, I purchased a new Navien tankless over a year ago and installed it myself. During the install I added valves to the water lines for easy cleaning if needed. We love our tankless water heater and highly recommend them due to our experience.

I bought this water heater ru-vid.comUgkx8G49mV71sAzUl9shXyLW-r3XgHH9EVh1 for use in my bus conversion. I installed it under my kitchen sink and it is fed by a high efficiency on-demand LP water heater. It is both a backup hot water source as well as a water saving device since we have hot water on demand rather than having to wait for the gas on demand water heater to finish its ignition cycle. I decided on this water heater due to the fact that it only draws 1300watts when it's ON instead of the 1500 watts that most Water heaters this size draw. In an RV a couple hundred watts can be a big deal. With very low standby losses, I don't have to worry about excessive power consumption. When propane is not available for our gas water heater, in conjunction with our low flow shower head there is enough hot water available to shower, albeit we won't be taking "hotel showers." Also very happy with the recovery rate of this water heater. Granted, it is quite small, but it does exactly what we need it to do.

Matt this is pretty great, but you've missed some absolutely crucial points. For example with your heat pump it matters dramatically whether you are heating or cooling your house. In your hot climate, the tankless actually outperforms what you're saying because it will decrease your cooling load on the house. Heat pumps are amazing. But in my cold climate, I need to heat the air in that space the water-heater is discharging to. So you might have a COP of 3-4, but your furnace for the house is what is actually heating your water and you need run it at the furnace's efficiency somewhere around 90% ( unless you heat your house with a heat pump too, or you had a heat pump water-heater with a evaporator outside of the house. ) Also, when you talked about a dollar of electric in or a dollar of gas in, you're missing that the BTUs a dollar of gas and a dollar of electric can provide are wildly different. In some areas they are comparable, but in my area where I know the rates, a dollar of gas will get you 4X the BTUs as a dollar of electric.

This is our first winter w a Rheem 50 gal Heat Pump Water Heater. Have been watching you for years and chose it because of your prior videos. We live in SC and the heater is in a closet off of garage where our IT equipment is. We leave the door to the garage open because the heater chills the room down to meat locker conditions! We love the amount of hot water! Previously had an 80 gallon standard electric and it couldn’t keep up with our use.

Wow, thanks for this info! As a total energy nerd, I am in the middle of doing these numbers for several products. Great video!

Great channel Matt. I always look thru your videos before I start a project. After seeing a couple videos of yours discussing heat pump water heaters I decided my next unit would be of that design. So last fall my old electric water heater died and I went with a Rheem hybrid unit. Wasn’t cheap, but the $500 tax credit, it made sense. Plus it had a dent in it on the back when it was delivered(didn’t bother function) They knocked off $450 for that damage. So far I will say I’m impressed. The energy usage is significant compared to the old one. I have a solar home here in Nebraska so every little bit helps. Thanks for always having good content.

Ideally value these product analysis videos. They are how I ended with my Mitsubishi hvac system. Keep them coming

The instant I installed my Rheem heat pump I noticed a _significant_ difference in my electric usage. I don't think you could make any other change to your home which would produce results like that. I highly recommend it to all my friends.

My family owns the largest pool & hot water solar company in florida. We install a ton of roof top collectors now backed up by a heat pump water heater and the results have been phenomenal. If they have gas sometimes we back up with on demand gas

Good stuff here Matt. Extremely helpful to someone (me) looking to go from a tank gas in my attic to another option or maybe even stay the same now.

Thanks Matt for all your videos I’ve learned so much in the In the research of building my future home. I wish I had someone like you in my neck of the woods up here in Michigan. I feel like I’m going to have to educate all my subs on the products they need to use.

Thanks for putting this information, analysis and comparison together.

Love this video thank you!!!

Excellent video Matt. Casey on the "Conscientious Builder" was talking about mini splits for heating. Electric heat or electric hot water is the only fuel source we as home owners can subsidize (solar/wind). Where oil or gas will keep increasing in cost. Thanks again Matt.

Thanks Matt, great info 👍

Great review!

Incredible video. Exactly what I was looking for. I didn’t even know these heat pump heaters existed

My 46 year old gas powered tank just quit. I was looking at tankless until I learned about hybrid heat pump technology, seems like a no brainer. Great video. Hello from North Austin.

Exactly the video I was looking for thnx

Great video Matt. I had a few issues when researching a heat pump unit for my house. Very few plumbing companies want to install heat pump units because of the nature of the pump itself, where it's more of an HVAC unit and less of a plumbing issue. I'm right down the road from you outside of San Antonio and can't get much luck with installers.

Did my research 5 years ago and was sold on this unit. It was not easy to find! Thanks for chart!

I've got the smaller version of that exact unit and it's been great. It's in a small utility closet next to the garage and directly under the attic. I plummed the air intake directly into the attic, so it's pulling in air that is 120-130 degrees already. Then I plummed the cold air out into my garage and added a small fan. Helps to keep the garage cooler in the summer. Also, tracking energy usage and its coming in at 10% of the original electric resistance heater. Crazy energy savings!

Good shit!

recently did this exact project. Older gas tank failed, replaced with a 50 gal. Richmond (Rheem off-brand) heat pump hybrid. It sits next to my furnaces, so has a ton of waste heat from them to pull from in the winter. One suggestion to Matt - when talking about heat pumps, use a sponge analogy to describe the movement of energy, not 'heat', in the refrigerant cycle. The compressor loop is moving an energy sponge (refrigerant) from a source (geo/air) and then squeezing that energy out into whatever your trying to heat. It runs the same for cooling, just backward where the sponge is soaking up energy from the house (or freezer, refrigerator) and squeezing that energy outside.

My wife and I wound up replacing our water heater with a model that includes a heat pump, based largely on the information provided in this video. We have been very happy with our reduced energy costs and it's nice having a little A/C ducted out to our garage in the summer. After local and Federal rebates, the model we bought cost us no more than a normal electric water heater would have, but we're looking at saving over $200/yr on our electric bills. This means it will pay for itself in about 3 years and be a bonus every year after that. Complete no-brainer to install one of these, provided you can duct the output so that it's not competing with your heating in the winter.

We love our Rheem heat pump water heater! Here in VA I put ours in a utility closet and it's ducted to pull the warm, moist air from above the kitchen and dump cool, dehumidified air on the back of the refrigerator via a wall vent in the utility room behind the refrigerator. I like to think that the fridge and the water heater are working together to save me money! :)

Thanks, Matt. Great tip, as I am prepping for solar and also a basement remodel. Current gas tank WH is in tough location for my proposed layout. (based on location of flue) Going to check out heat pump options and relocation potential. Cheers!

Thanks Matt! I thought for sure you'd finally be talking about your ECO2 (formerly Sanden) unit - been waiting for that. I see a lot of comments about northern climates and how this won't work - mostly people hypothesizing. As someone living in the north (central WA state) who switched from a NG furnace, dryer, and water heater to heat-pump-based alternatives, I can tell you, it works just fine. My solar panels supply every watt (net metered not off-grid) and I pay a whopping $8 a month (just a grid-connection fee) for all my utilities and most of my vehicle fuel (2 EVs/ 1 ICE). In my case, I built a small insulated (for sound) mechanical room in my basement that houses the washer/dryer, water heater and central air handler. The washer and dryer supply some heat to the mech room, which gets circulated to the water heater and a portion of the supply air for the air handler comes from the mech room so it all gets circulated through the house, reducing cold spots. Overall, I haven't noticed a significant change in my electricity consumption, and I track it all pretty closely. No more NG bill (formerly $20-$80/ mo depending on season). For comparison sake, basic household details - 5 person household, 1960's 1500 ft^2 house with some basic insulation retrofits.

My hot water heater is aging and had been repaired once already, so when it goes, I'm going to really consider a heat pump. Thanks for the information!

I'm in the market for a replacement water heater, so this is extremely helpful!

Great message! Heat pump dryers are also very cool and I hope they can cut out more of the market like heat pump water heaters are starting to do.

loved this show we are going to be changing our water heater and now I am going with a heat pump water heater

Great video. I have a 65 gallon Raheem hybrid which I mounted high in a garage. This thing is crazy efficient. I use only 3-4kWh per day for a fam of 4 in a 2500sqft house in MD. I run it in pure heat pump mode only. It cools and dehumidifies my garage which is a bonus too. One day I decided to switch to pure electric resistance mode all day to track usage and we used 12kWh vs 4 kWh. This blew my mind… I had no idea. These things crush and besides running a condensate line, it’s easy to set up

Thank you so much for mentioning the tax credit!!!

Such in-depth analysis. In your previous videos, you compared tank heaters with tankless and had me sold on tankless. Now, I have to rethink this as we move forward with our design/build plans for our new home. And sponsored by EPA! Kudos to you and your team for that accomplishment. That's quite an endorsement from them as to your credibility. BTW, I tried to download your Halo lighting plan, but couldn't. How can I get a copy?

Thanks!

This is a great choice. I love my RHEEM HYBRID water heater.

Used a Rheem Boiler that heats the floors and does our hot water. Works great and doesn't seem to use much propane, which is good when you're Off-Grid.

Great episode, timely for me at least. Thanks! By the way, have you ever considered doing an episode about water sprinkler systems?

I'm only two minutes in the video so far so maybe you cover it at some point, but I have been using an electric tankless water heater for about five years now and absolutely love it. It obviously never runs out of hot water, my electric bill got reduced dramatically after ditching the old 30 gal electric tank, and the unit itself was only $300, far cheaper than any other style you have listed. It has never had scale built up on it even though I'm on well water, and I've only had two repair it twice, which were very minor; one blown fuse and one time the little spinny thing in the inlet pipe got stuck. Other than that I've done zero maintenance on it. My unit also has a lifetime warranty on the electronics, exchanger, and elements. The only downside is I had to hire an electrician to add some breakers to my electrical box as the water heater requires three, 40amp breakers. He didn't charge much though the even if you factor that labor into the cost, I still came out cheaper than the options you've listed TLDR Show some love for electric tankless Matt! Edit: I should have also mentioned I love the small footprint. My unit is smaller than a suitcase so it can fit easily in the back of a closet, I don't need a full size room like you do with a tank unit and since I don't have to worry about gas, it can go anywhere.

This is a great video. As an BPI energy analysist, I always recommend replacing water heaters with a heat pump model.

We went with the Rheem heat pump water heater 2 1/2 years ago and don't regret it in the least. Keeps the basement cool in the summer too.

Matt, Good video. I waiting for you to review a Heat Pump Dryer and a combination all-in-one washer/dryer.

Thanks for mentioning Sacramento! Very helpful video. We are debating tanked gas, tankless gas, and heat pump electric. I believe the SMUD rebates have increased a lot since the video.

Great info. Coming from electric heaters to gas in the north, I like that I still have hot water in a power outage.

I went from a high efficiency power vent 50 gal gas water heater to a Rinnai 199000 btu tankless. I have a family of 5 and my monthly gas usage went from 15‐18 ccf to 8-11 ccf. I set the Rinnai to commercial mode to get 140° max temp. I was shocked how much the gas usage was reduced.

Another very informative video Matt, thanks. I live in Minnesota and currently have a Naturally vented Gas tank water heater in my basement. I am exploring replacing it with a tank heat pump. If I chose that route, I will also have an ERV installed to improve indoor air quality. ( Already have an HE Gas furnace, Going to cost me in some electrical box updates but I feel it will be worth the investment)

Great video... I purchased one of these 50gal heat pump water heaters a few months ago (against the recommendation of the plumber) and have been extremely happy with it. You mention in the video bumping up the temp on the water heater and using a booster valve to inject some cold into the hot discharge to prevent scalding but didn't come back to it in the video. I wanted to do this on my HP heater and was talked out of it bc the plumber felt the valve would trigger the vacuum break on the cold inlet... Would love to hear your thoughts as you finish the install of that proterra.

Matt, long time follower, doing an addition in NC. I just installed a climate master geothermal QE series heat pump that has built in “dedicated” water heater. (Not to be confused with a desuperheater). I think a geothermal heat pump water heater beats all your options for efficiency. The water heating is almost free during summer when A/C is on. It has backup elements but I leave the breaker turned off so I only use the heat pump to heat the water.

Excellent information! Thanks. Wish you would do a break down on in home solar. Just can get my head around the TOC on that nor a ROI

Great topic to cover. I'd be interested to get more understanding in how they work in colder climates, where they should be installed, performance differences with colder air sources, etc.

Thanks for everything here! A lot of videos about heat pump water heaters fail to mention placement. I'm glad that you did. I do have one comment to add. If you set this unit in an heated area, drop that UE factor to one or below and there is no efficiency advantage over a standard electric water heater. If you have to spend energy and money on space heating for the water heater to cool that same space you won't see any efficiency gains. There are some comments about the benefit to the unit acting as a dehumidifier, so there could be benefit there. I'm in the north, with very dry air. As much as I love this tech, it's the wrong fit for my climate.

We are looking into hybrid water heaters. One drawback seems to be owner complaints about noise (see Green Building Advisor and big box website reviews). In some cases 70db or like a vacuum cleaner. For units where that's a problem, you could use mineral wool batts or blown cellulose to attenuate sound from your mechanical room. Easier to do in new builds or remodels. Where it's just a tank being replaced, owners may have less space to add sound dampening and it's an extra expense in any case. As for Mr. Risinger's new hot water heater, it's an ECO2 System's SANCO2 unit (saw it in his water softener post--Jake Bruton has the same appliance in his home) and the compressor is outside the home, so there won't be a noise issue. But they are significantly more expensive.

Wow, EPA as the sponsor...proof positive that this channel has moved up a into the real big leagues now. Great job @Matt and Team

My 23 year old water heater is going out. Looking to purchase a more efficient water heater. This was very helpful Thanks Just checked for rebate’s in my area. Zero. That figures.

I recently moved into a tightly sealed condo unit. Humidity tends to be on the high side during the winter months. I'm thinking of replacing the electric resistance water heater with a heat pump water heater. It's located near the kitchen and I like to cook. Lot's of excess heat and humidity generated nearby. Someone in another comment mentioned the heat pump water heater installed in their basement dehumidified enough that they no longer need to run a dehumidifier! This solution sounds perfect for my place.

Great video, Matt, and this is great food for thought for anyone who's looking to replace a water heater. In another video, you mentioned the life span for a tank water heater. For a heat pump type, is the lifespan about the same as a traditional tank heater?

I can attest to that exact same water heater’s performance. When I installed my Tesla solar I switched from a propane water heater that was running me roughly $800+ a year (anybody with that lives with women understands), after rebates, it would have paid for itself within the first 6 months (I say would have because being solar I hardly pay for electricity) I am glad I had the forethought to plan my solar system around converting to an all electric household (including transport; biggest saver). The only thing left is my propane furnace which being a 95% unit is hard to get an ROI on a geothermal system within my lifetime.

I'm building a home at 7,000 ft. in Wyoming this summer. The water heater will be installed next to the gas furnace in a utility room next to the kitchen and dining areas. Winters here regularly dip to minus 10 degrees (and sometimes minus 30 degrees), winter well water is icy, and winter interior conditions are super dry (we have to use humidifiers). As much as HP water heaters save in warmer regions, I wonder if I can even use it under conditions in this area, and that's not even considering the noise the HP unit would make so close to the kitchen and dining room. I wish Risinger had said more about noise, incoming water temperature, etc.

Thanks for your awesome video! How does this fair using a water mixing valve externally? These are available at Homedepot which is where the cold water mixes outside of the tank, not shocking the already hot water in the tank? I installed one of those and noticed my bill go down (all electric tank) and it seemed to help recovery.

Pulling temperature out of freezing air actually can happen. As long as that evaporator is colder than the air outside so that the outside air can warm it up. Unintuitive at first, it may sound. You got this spot on Sir. Tesla stepped up their heat pump game in their cars too. That cybertruck is gonna be built in your neck of the woods in the next year or two. If you like heat pumps you would appreciate those cars HVAC systems. Great video!

Great video, Matt! What electric service is required to operate a HP hot water heater? Thanks again, and continued success!

I wouldve liked to see the comparison with electric tankless as well

Awesome informative video, one challenge i do have to electric heat is when the power goes out in the north due to snow storms or other nasty storms. Gas heat is reliable in these time. As people make the shift to more solar or wind power with back up batteries I could see this really taking off

I'm surprised you didn't talk about utility hookups. As I understand it, in many cases switching to tankless means boosting your gas service which can be expensive. I'm wondering if we could switch from gas to electric heat-pump with our current electrical service. I will have to explore that when it's time to replace our tank.

Very very helpful. Would love to see you add comparison to indirect hot water heat. My hot water tank just failed completely. I’d like to convert to heat pump, but the two costs not included in your analysis are the costs for getting electric outlet installed, about $1,000 estimated to put in 221 volt outlet, and the costs to get through an exterior wall for the condensate line. Even with great energy rebates, I don’t think the financials work. My summer time natural gas use for hot water is only about 10 therms per month or $12.70.

Hi Matt, love all your videos! I live in the Pacific Northwest and concerned about how cold the basement will get during our winters. Can the units have a cold air venting to the outside? If so, can I disconnect in the summer to provide cooling?

New to your channel and love the content. My question is best brand of water pump heater. I have heard a lot of negative things with both Rheem and A.O smith as warranty to how they don't honor them and units not making it past 3 years with issues. What have you heard about Bradford white?

Coming from a Northern Climate I made the switch to Tankless from a Heat Pump. Biggest reason was BTU loss due to recirculation loop. The loss was too much and caused the Heat Pump to operate almost non-stop. I have since changed out the recirculation pump technology and moved from timer base to motion sense in the bathrooms and kitchen to trigger the pump. Seen a drastic drop in gas usage and would love to test the Heat Pump again.

Great info! Thanks Matt. Could you please share which electric heat pump unit (make/model/size) you have in your house? I also have a large number of people under one roof. Thanks in advance

Great video Matt, I am not sure if I missed it, but when it comes to placement, I didn't hear anything about a size requirement of the space that the water heater is going in. If the space is too small a heat pump water heater may not be able to function properly

You are a GOD

Love the heat pump water heater for most of the year. I live in the north and normally in winter time before the heat pump water heater my basement was about 60 degrees in the winter. Since I put it in my basement is around 40 degrees and the heat pump struggles so I have to run it in electric mode which is costly

Another great video! I just ordered a Corro pro-tech powered anode to install (tank maintenance, drain / clean) in my existing GE 40 gallon (57 gallon first hour) dual element resistive electric water heater that I think is about 14 years old. I turn the water heater up a bit many years ago to keep up with demand I want to say at the tap my water is about 120° I'm sure I'm at the end of the lifespan for my current water heater. I've looked at the heat pumps for years and I've watched all your videos. Currently there's four of us in the house my wife and two daughters both older teenagers. The old GE electric water heater has a 57 gallon first hour should I go with a 50 or 80 gallon heat pump and would you stay with the AO Smith or switch over to the Rheem? I've been with you since you started your RU-vid channel and appreciate all your content, Thanks

Unfortunately the Federal tax credit expired 12/31/2021. So add $400 to that side of the equation. Also, lots of Southern homes use the attic for the water heater storage and the temperature extremes fall outside of the effective range for Hybrids (+110F in the attic during summer in my area). I'd still like one, but something to consider.

Thanks for the video. I currently have a 75 Gas Hot water heater and am considering moving to a Gas Tankless or a Heat pump electric. One of the factors i think you need to talk about is the fact that the tanked water heater will need to be replaced every 10 years or less. It seems like the consensus is that tankless water heaters last longer than that with proper maintenance. I don't think there would be enough servicable space to allow for me to replace the sacrificial anode, and I have a water softener so it's pretty harsh on water tanks. You have to factor that into your calculations as well. I would be installing my water heater in a finished basement with conditioned air. I live in the northeast and we get cold winters and hot summers. In the cold winters the heat pump would be drawing conditioned air and pumping cold air back into my basement which is where my home office is.

In a hot climate they seem such a good idea!

Plus on a heat pump water heater, you can collect the condensate water in buckets and do your laundry with it.

Let's get going! 🤪

Not sure if someone already commented on this but one thing that must be considered is electrical requirements. Our previous home was in the mountains of Colorado. NG was not served to our home so when built it had two 50 gallon electric water heaters which ran off 240v. I replaced them with one GE heat pump water heater. Huge savings on our electrical bill and no electrical changes required. Great investment. Our current home however uses a NG water heater. Therefore, if I wanted to replace it with a heat pump water heater I would have to have an electrician come in and run 240v to the location which in my case would involve a sub panel as well. I live in the PNW and in my area this would probably cost upwards of $2000 which really puts a dent in the ROI. IMHO heat pump WH are the way to go if you are replacing an existing electric WH but if it is NG it probably isn't cost affective (unless you already have unused 240v at the location).

Hi Matt. Thank you for the great videos. My question is would the 80 gallon electric Rheem Platinum hybrid be capable of replacing my oil fired boiler on a 3 zone baseboard system. And would this be a practical alternative to get rid of the oil boiler in my home. Thank you. Len.

Hey Matt what about the gas tankless combination boiler that do both hydronic heating and domestic hot water for those of us in the northern region I would love to see her does that match up.

Matt: WARNING - We purchased a hybrid water heater for our new house last year. It was by one of the manufacturers you reviewed. The problem is the noise. I researched the brand and two different people at the manufacturer stated it would be 49 decibel, similar to a refrigerator. I can state it is 75 decibel which is really loud, like vacuum cleaner load. Imagine having a vacuum cleaner start up at 3:00 am in the middle of your house!!! Currently the water heater is located in our utility in the center of our house next to the two bathrooms to minimize wasting water at the showers and faucets. However at 75 decibel I run the water heater in the electric mode only which is not a cost savings. It will be relocated to our unheated garage in the near future, about 45 feet away but at least I will be able to hear the TV without having to turn up the volume over the water heater. I would warn everyone considering a hybrid to research how loud they are before purchasing and installing one.

I wish instead of showing Dollars, there was the amount of input (electricity and/or gas) because that is a more firm number than dollars. What if gas prices goes up, down, or sideways? Same with electricity.

Great video. I live in Alaska. How would the heat pump water heater do in a room that had in floor heat? Also would you run in floor heat efficiently off this system?

Great concept, not a complete execution. In Michigan natural gas is cheap & the heat is on 8 months of the year. I would have loved seeing actual energy consumption, not just “costs”. Energy costs vary from area to area. In 2018 for a family of 7 we spent $23-35/mo over an entire year when the only natural gas appliance in the house was a tankless hot water heater. Our electric bill went down $85/mo when we removed the traditional electric hot water heater. My overall point is that for 8 months of the year we heat the house with natural gas. Adding and air conditioner in the basement (finished area for us) would cool the basement resulting in more heat input required, aka more natural gas usage heating the basement. Initial cost for a 60 gallon heat pump water heater around here is $2300 just for the unit. Installation is another $450 or so. Just doesn’t make sense in heat-primary areas yet.

Just did a DIY replacement of a 38 gal electric WH with a 40 gal Rheem heat pump.

For 3 years I tried to buy a Heat Pump water heater in British Columbia, Canada. After watching your videos (and others) it was a no brainer to pick this tank when replacing my 12 year old builder quality 50g tank. 50% of my electricity bill was from water heating ($150/2 month billing). I received so much, SO MUCH rudeness from local suppliers and installers when trying to find stock. All of them stating that they’ve never heard of this tank type, that it’s not as good as natural gas, that they personally wouldn’t install it because of some obscure “insider” trade knowledge alleging they’re garbage products while trying to sell me what they do have in stock, etc. I gave up swimming up stream and bought a Rinnai NG tankless. It was a more than disgusting experience TRYING to go green when the companies want you to buy wasteful crap.

Can you do an updated video with an electric tankless water heater included in the comparison?

Great job! What can be done about heat pump HWH cooling the basement in winter? Are there any cool "hacks"?

My biggest issue with the heat pump units is that i feel like you need to factor in the temperature loss around the unit. You are indirectly putting some of the heating cost of your water into your heating bill. I think they are probably more efficient than gas or resisistive heat but as a northerner where i spend money to heat my basement i would love to see something that takes that into account.

Awesome video. Ive shared it on a site in Canada for its no nonsense information. I won a tankless with install a couple years back. Im not sure how much more money it saves me from my old tanked power vent. I assume it does, since its not having water heated when IM not at home. Have I done the math, no. Heat pumps in this video work how well in -30 and beyond?

iThe cooling and dehumidifying effect of the heat pump water heater sounds perfectly made to be stored indoor to help the a.c. in our hot climate

I have a 65 gallon Rheem heat pump. The pump is very loud and I discovered that my yr had a known issue with noise. Had to spend $$ for sound proofing. That being said I have solar and a house battery so to hear the water is free.

In my recent renovation I went with a Rheem Marathon. Unfortunately we ended up with a larger size that what we wanted due to supply issues, but that's OK. It's a small house (

Loved the video still we started shelling solar. Solar is a bad investment to save on a 150-250 utility bill. Currently electrical grid can’t handle everyone going electric anyway. Come to Philly and I’ll show you what heat pumps do to the power line. It’s called they melt outta the air in the winter

Buying a HP water heater was the smartest thing I've done on the mechanical side of the house. No regrets!

This might be the single most useful video you and your team have put out Matt. There is absolutely zero reason for standard electric heaters to be installed on new home construction.
