Storing Solar Energy in WATER?! Homemade 3 phase Thermal Battery install!! | ØY08 

As a network engineer that builds ISPs for a living, I would love to see more sparkies cross the fence occasionally and work in the network world... Just the same as I would love to work in a sparkies world where networking stuff is needed.

That property has come so far since when you first went there for the galv conduit. Still one of the best plant rooms I’ve ever seen. All the trades that have worked on it clearly have a passion

I love seeing more and more people in the industry taking that extra step to really teach their apprentice how things work. We need more tradesman and technicians like that to ensure we leave the industry in better hands than we found it. Really respect the effort your going to Cory to teach young fella's like Ted how to do things properly. Sending love from Australia, I also take great care and pride in teaching my apprentices how to do their best job possible and always put the best foot forward to go that extra mile.

Ted is a lucky apprentice, I’m a second year apprentice and wish I was given as much information as Ted to soak in. Great electricians to learn from 👏keep up the good content 👍

Listening to your ferrule chat, reminded me of a saying I thought up recently. "Social media, where people are experts in everything but knowledgable in nothing" 😅

I wish all engineers took such pride in their work. I bought a house where the gas installer seemed to be the most lazy half-assed engineer in the world: leaky and damaged radiator bleed valves causing pressure loss (previous homeowner thought it was normal), terrible soldering (really sloppy and all down the copper, far too much used), uninsulated pipes, pipes too thin & bent instead of using corner joints, pipes too close to floorboards causing creaky floors. Then I had an install of a heat pump to turn it into a hybrid system, and they decided to neglect insulating the pipes on the lower floor, just because they couldn't access them - but they didn't tell me this, they just threw the insulation in the loft... Not only this but the heat pump installer said pressure loss is normal also!!! I've been slowly correcting the mistakes...

That's some plant room for a house. Excellent work as always Cory. Love watching the content.

Awesome video Cory! Is great to see such a huge set up and so well done. I enjoyed it being a geek myself! Lol. How great is it that Ted appeared out of the blue.

Accurately & intimately describes a relay without using the word relay 👍

I just noticed. You folks across the pond say things seriously that we use as baby talk. Like "zappy" or you call electricians "sparkies" Its neat because its so perfect for an explanation. P.S. i really like the quality of your work. You and Ollie are proper professionals but still have some fun on the job. 😊

The hamster joke finished me off 😆😆 In all seriousness though chaps, you lot are a different breed. This video made me feel stupid yet simultaneously driven to learn more 😂

The money just in that room alone. As a sparky and a gas engineer that’s is all done to a really good spec. Nice to see both trades take pride in there work.

What a great start for Ted and his electrical career. Learning from the best. Is Ted on the payroll now Cory 🤣

I think the client should look into adding Heat Pumps and / or Sunamp heat batteries to use up a excess generated energy, the Eddis could also talk to the Sunamp batteries much more effectively

Fantastic stuff, amazing work, great to watch

Great video, Cory, very entertaining. Enjoyed the b rolls. Good to see Tim In video videos.

I'm doing something similar with excess solar, except I use a monoblock air to water heat pump to make it more efficient compared to regular heating elements.

I'm watching all of your videos, absolutely love your content and it's right up my alley of interest at the moment! Hi from South Africa.

Another amazing bit of content. F’ing love this channel 👌🏻

Educational and well presented, a superb episode, and well done to all involved.

number one electric channel for me. thank you for sharing.

And another original episode. Another different installation of something other than a CU change, or a EV charger install... Love the content, waiting to see the Berlin work and what the Wind Farm tease was...

Highly technical and very interesting stuff....well done guys!!

That is a great install, except for the fact when the tank has to be replaced! LOL Keep up the good work sir! 🤠👍

Mate,That was a quality vlog,really enjoyed it.

As always amazing video Cory really learn from your videos

That's an absolutely WILD plant room for a residential property. I'm in love.

I love your work ethic Cory your videos give me motivation to change my life. Being taught some real knowledge,skills and safety

Great video. Nice to see something different that is helping the planet and the property owners wallet.

10:19 Oooo, to soon? Yeah, to soon, but hilarious! 17:05 , should you have said each phase? Did i get it right? 😉. Ted has a plan, good man, keep 'em. This is cutting edge stuff Cory, more vids like this is epic for all.

Great job lads, looks good !

your videos really give me reason after reason to finish my electrical course at college, this year anyway lol keep up the good work man!

Just commenting about the A1 and A2 going through the thermostat and overload (16:45). As you know because you literally pointed it out in the video- You only need to run either the wire going to A1 or A2 to break the circuit to the coil in the contactor through the switches. I always break A1 which is the phase the systems I build and connect the neutral to A2 or if it is 24v it is G to A1 and G0 to A2 or 24v+ A1 and 24v- A2 depending on the coil voltage on the contactor/relay. Best regards from Sweden.

Great job, well done to you all 👍

Brilliant job & video 👍

Really good job! I think drilling metal above a PCB might not be recommended, though. The risk is minuscule due to the silkscreen, but shorting traces can lead to misbehaving devices.

Great video as usual, I’m a carpenter so all this goes over my head but it’s still fun to watch

Awesome😍👏🏻

Teds a lucky bloke getting to learn from such a great sparkie like Cory.

As always, I love it!!! My only complaint is I wish you uploaded more 😢

Super interesting thanks! More geeky videos please! 😊

Great Content really enjoy watching and learning ⚡️👊

Lovely job guys!

That was amazing 🤩🤩

I usually call them spring nuts..they come with springs on the back of them..awesome video great job guys..

i chose the simple way , my panels connect directly to the electric element in the hws. i also have a 1400 litre sand and steel storage for cooking and providing boiling water, heats to 300 degrees celcius, direct from solar solar panels to elements in sand.

Great video, very interesting! 😃

How good is UNI Strut 🤤 probably a video in that. Bloody awesome job mate 💪

Good job! - lot of work & hardware on this one. Hope they have enough baths to drain down the tank enough for the input to go somewhere.

Great video. Really interesting.

that technical room in the house looks like a dream to me, i d sleep in there :D:D:D edit: at 16:40, that copper pipes on the water storage tank looks like they soldered a press fittings, never seen that in my life. the fittings looks like a V press ones being soldered...

Phenomenal install to be fair. Hoping to build a miniature version of this next year for my 1 bed apartment :D (the plant room will not be as roomy as on that million quid house) :p

🤣8:50 Ollie, be careful! 🤣

Spot on Cory

👏🏼👏🏼👏🏼 Fantastic

The only thing I can see this house the place is there is no capping on the Uni strut itself you’ve put in end caps on Apart from that a very neat and serviceable job

Great job 👏

As long as it is a stranded wire you have to put ferrules on it when its a screwed connection

Eddi, Eddi, Eddi.....................OY, OY, OY

“OY! There seems to be another video!“

0:15 That is one meme worthy smile, in the positive sense.

Why wouldn’t you use a single Eddi with their optional internal relay to cascade 3 immersions off the same phase?

Just a question on the thermal battery - this isn't a hot water cylinder storing hot water to be sent to the taps, this is storing hot water/fluid that will use either a plate heat exchanger or a coil within the battery to transfer heat to mains pressure hot water?

You often do not need to involve a inverter to take power from solar panels for powering a resistance load for heating as only a duty cycle limit to keep the resistance element from overheating ( melting ) and a thermostat to limit heated material ( in this case water ) from overheating ( in this case water from boiling and then causing a steam explosion ) . A bimetallic thermostat switch may have a maximum current but no minimum current and its lifespan is enhanced by use of low voltage and current through transistor controlling ( with snubber protection) the power to a relay ( usually called a contacter ? ) multipole single throw relay ) ) thus no need for the exorbitant expense of inverters for heating .

Nice job 2x👍

Always thought Zebedee,s had springs on them channel nuts where pain.

by using 3 eddi are you really getting 3.2 per device to the immerson thermostat, because i though most uk immersons from factory were limited to just 3kwh I know some are available with a 5kwh. it just seems silly to limit it to 3kwh

they made a appartment building, with batteries like that 10 years ago close to me

Love all of your videos! And would love to see more of the networking-type stuff. I was a bit confused by the daisychaining of cat5 here though - were they all connecting to a single RJ45/keystone on the switch end? Or multiple? My understanding was that ethernet can't be daisychained and needs a point-to-point connection, was it serving another purpose beyond what would be expected of usual ethernet?

Did you pull an ethernet through conduit and flexi beside 3 phases?!!

You should definitely label the 3 eddys "Ed, Edd and Eddie" in honour of the once great Cartoon Network.

Plant room is mental

Are heaters in delta or star configuration?

I see you have installed the Max Ad's Plus Pack on this video.....still as this was really interesting and different, I stuck with it! Good video.

hotrod is the greatest film ever made!

Cory well done

Nice 👌 just out of interest, why link the router/switches with fibre over such a short distance? And how is the design spec worked out (traffic volume / copper to fibre conversion latency trade-off / cost etc)? Would be interesting to know more about that side of things. I suspect in this case, fibre might have been chose just because the customer could 😂 💰

It's like something from Superman where he got wires wrapped around him ...

Great vid any chance showing how to use a cheap battery solution with existing solar panels if possible 🎉😊

The spring loaded ones are Zebedees, otherwise they're just channel nuts.

Looks to me like they’re are using the Wi-Fi in the room, you can see the wireless UniFi AP above the tank with its proud blue LED ring light. And not transmitting across to all the other devices wirelessly like a mesh network

22:00 so are the contactors always energised during normal operation? And the thermal cut out needs to be energised for the thermostat contactor to close?

Unistrut nuts are channel nuts , channel nuts with the spring attached are known as zebbadies named after a character in magic roundabout

Corey not sure why you have used 2 x contactors ? could you not put the overload and stat in series feeding 1 contactor coil ???

Question: if you store energy as heat, can you use it as electrical energy later? Or is it just for home heating in cold climate?

Not sure if this has been mentioned but SolarEdge also do a variable output for hot water, however I don't think this can be installed independently like the Eddi and requires a SolarEdge inverter.

Are you allowed to put communications cable and power cables in the same conduit in your country?

no battery? Assume they’re planning for some eventually? Is the hot water just for hot water? Wonder if you could upsize that and store to use for heating too?

Can you put this on a hydro system?

Try the milwaukee jig saw for cutting metal with metal blade. You will never use the grinder with zip cut disk again.

some det up for a house... love to see it......wouldnt like to be paying for it lol

Looks pretty straightforward to me. 😂😂😂😂

At what level do you become a prosumer? And at what level do you go beyond that? Prosumer stuff seems pretty normal to me.

Wow very impressive but I'm sure not really economically viable. Any ideas on the material cost, tank and the Eddi etc. Great set up Cheers from Oz

They went to all that trouble fitting high end vaillant kit and then stuck the UFH on a fixed high temp mixer and then on/off zoned it to death with stupid room stats. There is a ton of energy to be saved on the heating set up alone. Call me if they want it doing proper like.

Damn. I only hope grouping has been applied to those wires bunched up with cable ties.😉

So, once the thermal battery is all heated up, how does one extract the energy? Is it just an electric hot water heater or does it actually produce electricity from the heated water?

How much is the power bill, before and after (at current tariff)?

Is feed in tariff not a thing anymore? My old boss gets something silly like 60p a unit fit payment as he had his so early where as my dads is only 20pish.

Can you explain more about this 3 phase thermal battery? Is it a close system for heating or act as a boiler?
