2PSI LP Residential Gas System 

Dude, thank you for this video. I've been googling all over the place and couldn't find direct answers and your video answered what I needed. Well done good sir.

You did a great job and this is coming from somebody with 35 years in the field but I would like to go over some shortcomings.#1 at your tankless water heater you installed the shut off after you're flex line. The best practice for this installation would be a shut off valve before the sediment trap (drip leg) and the regulator.#2 just because they regulators are stamped 11" does not mean its necessarily so ( lock up and working pressures should always be tested after any regulator is installed).#3 two pressure tests should always be performed. I realize you did the one after installing your fuel runs which is fine but a second one at operating pressure should have been performed with all equipment connected ( this will ensure that all connections and equipment gas valves are gas tight, nothing passing gas or leaking). Other than my three concerns you did a fine job, keep it going and stay safe out there.

Good job on the black iron especially the manifold I like it!

It just amazes me how much you know about the building of a home and the installation of utilities and appliances, i really enjoy all of your videos! So very informative and exciting! Thanks for sharing! 😊👍💕💕💕

Gracias por compartir sus conocimientos con los que no sabemos casi nada, lo digo por mi, muchas gracias, boy a mirar todos sus vídeos para aprender de usted, muchas gracias y hojala y siga compartiendo sus tremendos conocimientos

Of course another great video!! I think doubling everything up for the upstairs/downstairs is a great idea for efficiency! The 2PSI system you're doing is a great idea for what you guys are doing! Great job Paul! You guys are a great source of knowledge and ideas!

I would recommend 2-1000 gallon tanks and with your space bury them. 3200 square ft home in Pennsylvania (depending on the winter) uses 1500 - 1800 gallons a year.

This is an interesting approach to solving your gas supply issue. If indeed it will work, it is impressive. Here in AZ I would have to supply a design plan to the gas utility for approval and they might require a licensed plumber to do the work - though I am not sure if I could do the work or not. You might want to consider putting a water filter in your water lines to your two hot water heaters. From what I understand, the biggest problem with the tankless water heaters is that hard scale builds up in them and they are very hard to clean. If you installed filters to eliminate the calcium and magnesium from the water, you would eliminate having to descale them on a regular basis. You will need more than a carbon filter but be careful because an RO system will make your water very acidic and it will eat any copper piping in your water heaters or water lines. Check with a water filter company to see which filter works the best to eliminate hard water ions. You could go with a salt system, but I despise salt based water treatment systems. I am betting there are well water filters which will do the job. It's important to ONLY treat the water going to your tankless water heaters. If you want your hot water to be potable (for cooking), go with a carbon filter system with 3 - 5 stages. They are very cheap and they make your water taste amazing. A 5-stage system will probably eliminate some of the hard water ions. The carbon filter systems can be sized to filter ALL of the water coming into your house and you can buy them yourself and install them. They are easy to install and maintain. I hope this helps you.

It is entirely possible that I am wrong, but I believe that you have to test for leaks at a higher pressure then the "usual" pressure. Nice job.

3/4" black pipe 2lb natural gas can deliver 970,000btu. Few things about LP is that when it leaks it pools and settles low...which is the perfect situation for explosions. In high efficiency applications LP is more acidic when it condensates. Having multiple regulators kinda stinks. Few years back built a large lake home with LP service and we vented all the regulators like you would a commercial/industrial application. I love having natural gas...endless service.

SUGGESTION, We put a propane tank on a property in NH. What we did was buried a much larger tank than yours, maybe 4 times as big, don't remember. My point is you will be using more than average amount of gas, with the large tank we waited until gas was cheap, yah right cheap, we. Bought it at a much lower cost because we waited when the price dropped and we bought allot at once. Not to mention those above ground tanks are just ugly. ENJOY YOUR VIDEOS, QUALITY WORK‼️👍👍.

Buy the 1,000 gallon tank, DO NOT lease or rent it. This will allow you to shop around for the best price and customer service on propane. A 1,000 gallon tank can be legal filled to 800 gallons which is plenty to run everything you will need household wise as well as run a standby generator for a LONG time. It also allows you the flexibility to wait until propane is on sale or at a low price from any propane seller you want as opposed to being forced to buy propane from the company you rent or lease your tank from. They almost always inflate the price. The other thing is PLEASE plug those unused propane outlet pipes attached to the cutoff valves if they are not currently (kinda difficult to see in the video) Curious little hands from children love to play with them and could be in for an ugly, unwanted, and dangerous surprise in the event of a spark or static discharge.

Wow. That's pretty cool. Just so folks know: 2 psig = 55.36 in water and the standard 11 in water, is about .4 psig. You can move more gas with a bigger pipe / higher pressure. Six of one / half dozen of the other. The cost saving is making it pretty popular in new construction.

Thnx for your help excellent information.

Always plug unused valves. Never trust the valves, or rely on nobody accidentally hitting the handles. But, Blue Monster is the BEST tape. Love that stuff.

Water will corrode the metal pipes and cause oxidation. Use a leak-detector fluid made for this application. Great video

I love your videos Wish I would of seen them before I did some of my renovations.

Just an observation, but it would likely be much cheaper to install a 12 KW, grid connected solar panel system. You have a lot of land so you can install a ground mounted system. You could install it yourself for around $15,000 and your payback period would be 5-7 years. You could use two high efficiency heat pumps to heat and cool the house. One heat pump would be for forced air heating and cooling, and the second could be used for your under floor heating and cooling. This would probably be your best energy choice because you have a large house. Heating it with propane in the winter will be expensive and you will still have to buy electric AC units. A ground mounted solar panel system is by far your best option.

Hey Paul, thanks for the clarification. I know I was pretty clueless and I learned a few things from your explanation. As always, outstanding craftsmanship. I sure hope propane is cheap out there haha.

Good job on the pipe tape!

You should install caps on all of your manifold valves that are not being used as a 2nd safety

You need to install plugs in the open holes on those valves for redundancy. Those valves can leak or get knocked open and you’d be kaboom.

all open ports should be capped until use to prevent accidental gas discharge until use.

Appreciated!

Thanks

Keep up the great work.

You know that end part about being allowed to do these self-builds is really important and it's a bit difficult trying to find out what you need to order permits for and be certified for and etc. If you could do a video on your experiences and knowledge of that I'd really appreciate it.

Cap those outlets on them valves guy.

Thanks!

Thank you.

The second stage regulator is usually adjusted between 11 and 13 inches of water column. Your appliances have their own regulator that will regulate it down to 10 or even 5” for two stage gas furnaces. You need to understand that propane is not made to run on most appliances. They are designed for natural gas. All we do is change the pressure and orifices and nothing else on most appliances. They burn dirtier, and usually don’t last as long on propane.

is that a 3/4 stub out at 18" high??

Very helpful, thank you.

Why you dont put a shut of valve outside and a union after the regulador?

Do you think its going to be an issue having the regulator so close to to power outlet? Seems a bit strange to have the gas line touching the outlet

This may have been asked and answered already, my apologies if I missed it. Why put the regulators at each appliance, instead of putting them on each outlet of the manifold?

Good morning from St John Parish, Louisiana 27 Oct 20.

good vid! could that reg below the water heater been wrenched more maybe?

Man I still can’t believe you’re gonna run that whole giant house on LP! Did you consider geothermal heat pumps? Probably would have paid off the difference in less than 10 years, maybe 5 with how much LP you’re gonna go through. Your house your call though. Love the build, thanks for sharing with us!

What are the downfalls or cons for going to a 2psi system?

Couple of questions. Why did you choose a tank less water heater? How did you decide of which on you needed?

I need to do this in the spring. I have a 96k furnace, gas stove, and a 60k garage heater. From everything I have read so far I need the maxitrol 325-3L -1/2 with the vent limiter on all 3 devices. The 325-3L says it handles 90cfh which totals 226,530btu. Can someone confirm so I don't order the wrong parts?

No bidy ever explains what the FF water column is. Geeezz

Will it help with the amount they can fill in you tank if you bury your tank?

How is it you are allowed to have a gas line touching an electrical box and line?

Yes very helpful, but do you have to have a regulator on every device? I’m in Texas and I only have 1 regulator on the tank and none on my other devices?

Why would a regulator be venting?

11 inch water column = 0.4 psi.

How do you verify that the maxitrol regulator pressure is set correctly?

The 325-5L seems pretty big since they handle 90CFH LP = 226,530BTU

What happen to your retaining wall?

I work for a hose company and have installed hundreds of pipe connections that will go towards use with propane using non propane rated tape. Haven't ever had one come back or heard anything negative in doing it this way. Can anyone explain why you would have to?

I'm kind of confused why you decided to put the 11"WC regulators directly at the appliance rather than directly after the manifold. I think the restriction that you'd have to worry about is line leading to the manifold, right? EDIT: I guess the requirement to have them horizontal could make packaging them off the manifold might be tricky, so putting them at the appliance might make that a bit easier?

The regulators that you put on the stove and the in-line water heater were the same capacity as far as inlet and psi out but they were very different sizes… Can you explain why?

How long will one tank last? How much was it to fill it?

What kind of pipe did you run in your home?

What I don't understand is why this couldn't be solved by a larger pipe supplying the manifold, and home-runs for each appliance (which you seem to already have). You said all but one run is short, so it doesn't seem like decreased flow from long pipes is a problem (you could just have the kitchen be a 2psi line). I feel like I must be missing something, but what?

It's a shame that your website cannot be accessed from Germany.

Won't you need to bury the LP tank to keep it warm enough for winter use?

Why didnt you bury two 500gl tanks

If you had put a manifold outside the house where you have the 2 psi regulator and put 4 regulators at 11" then had each regulator run 2 appliances you wouldn't need any at the equipment, or any inside the house. This would of course turned 1 wall penetration into 4.

I dislike Fisher gas products. Rego is a superior product.

2psi is how much in the "WC" formula? 10-14 inch of "WC" is just 0.5psi.

I think I would have amed it away from electric outlet
