Thank you very much, sir for your time explain very well everything😎✊

Does not connecting you hub to your WiFi can they not gather readings that way my hub is connected to my WiFi

Johnathan if you are looking for new technology water tank have a look at a company called Mixergy. I can’t recommend them enough I’ve just installed a 210l slimline tank which heats up over night and solar diverts when battery full. It heats from the top down and water stays hot until you have used every last drop. It’s the equivalent of having a 7-10kw of battery storage depending how hot you have your water.We would have installed the heat pump version but didn’t have enough room.

Thanks for being an early adopter. Your experience and many others have shown that these are not the solution.

Profit is a dirty word and thats why BCA and others get so shirty about stuff like this. I'm happy for everyone to make profit, so transparency would help put people at ease. Yes, everyone makes profit along the way, how else would people feed their families? This sort of secretive nonsense needs to stop - there's just no need for it and it breeds further scepticism and distrust. Maybe BCA should open back up to the public again instead of locking them out of this area of the market?

I don't recommend that anyone have a smart meter installed. I moved into a property 5 years ago that had a SMETS1 smart meter installed. The software to the meter was upgraded a couple of years ago, but I've just received my latest monthly bill from Eon Next for the extortionate amount of £859. The bill has been generated using an erroneous smart meter reading. I live in a small 1 bedroom bungalow and have definitely not used all that electricity over the past month. Since Eon Next have generated my bill, they have taken all the credit that was on my account and state that I now owe them £288. I'm now in the process of waiting for them to sort out this erroneous bill, generate a refund back to my account, and generate a new bill using a correct smart meter reading, etc etc. I'm now thinking of changing supplier

I've just had another look at your original 'My Sunamp has failed' video, and I notice that you're using the same small expansion vessel ? Is there a specific reason for that ? I've just had a 300 'X Plus' installed, and my expansion tank is much bigger ? (I don't know if my larger vessel was specified, or if it was just the one that was 'available' ?) I just wonder about it, because 'it' is the same, and the problem seems to be the same, - too much pressure 'somewhere', making something 'burst' or leak ?

I'm with octopus and have a Smart meter. And I get a bill every month that is paid off via a variable Direct debit. i.e. I pay only for what I have used each month. Works flawlessly. But bad signal areas have always existed. Nowt new!

I'd suggest a heat pump hot water tank if you can afford it.

Years ago -right at the start of the internet boom , there was a pilot project to deliver the internet over the power supply cables. I believe it worked..... WHY , why , why did they not use this technology for the "Smart" meters.... en.wikipedia.org/wiki/Broadband_over_power_lines 🤷‍♂. Interested by your opinion of Octopus .. this is certainly the sort of thing that would make me switch to them...I'd just like to find out whether you just got a good 'un (Ryan) or whether it's a company -wide culture ....🤔

The red 22 leaf sold at 12 200 buyer fee included . It was a techna model , it's now available @ 16, 750 on auto trader

Ah yes, a "weird box thing" (also known as a QR code).

Your currently pulling 2 Watts! That would be proof to me it's not working unless u have literally absolutely. Otjing plugged in anywhere. You tv standbys and microwave and cooker clock and octopus mini etc etc will definitely be using more than 2 Watts!

Thank you for the tip about the QY-7221. Unfortunately, the original touchscreen is really poor quality.

Your a muppet, this is not the answer to transport ,batt cars are rubbish end.

My SunAmp is coming up to 4 years old. I have had no issues, I noticed that the heater element max is 2.8kW so I adjust the eddi to max out at that. I've heated it using both my ASHP and the Eddi in that time.

I prefer the simplicity of a solar PV system that diverts excess power to the HW tank element via the EDDI, which has worked well for me for the last five years. In my case, gas consumption has dropped by 1500-2000 units each year, or 15-20% of the typical annual figure. Nearly all the rest of my power is consumed on-site with minimal export, despite the lack of battery storage.

Shame, hope the sodium acetate didn't leak. I'm sure heat batteries have a place for some applications.

The technology is great, but the manufacturing is very poor

Does it have a pressure relief valve? It should have for safety. Water expands a lot even at temperaturs well below boiling. If no taps or appliances are drawing off water your hot circuit will gain pressure as heat is applied and has to go somewhere. The expansion vessel is there for normal operation but has a limit. That one looks tiny to me. Could be they needed a larger expansion vessel.

Agree with all comments here about moving to Mixergy, had mine for almost 3yrs and works perfectly and combines well with the Eddi for the solar divert.

If you have space I highly recommend installing a Jaspi Ultrastore. They're approximately the same size as a fridge freezer, hold 500 litres of water and allow heat input from multiple sources. Ours is set-up to use a heat pump, solar thermal and excess solar PV, but could easily use overnight cheap rate electricity. It then provides all our central heating and hot water, it can also store enough heat for about two days of demand in winter so if there's a storm forecast we'll boost the temperature up to 95c in case of a power cut.

We used to have a Sunamp (Low Temperature/larger unit) but swapped over for a Mixergy tank a year ago. The issues we had with the Sunamp were that it not really work with our low temperature heat pump and offered little control ( with its on/off switch). While the Mixergy tank with its app and online control works so much better for us.

It could be the vessel isn't large enough to allow for the expansion. And make sure the precharge air pressure is the same as your cold water pressure so that the vessel has max expansion volume while it heats up.

Fuel consumption is only part of the running cost. Purchase cost, interest payments, insurance,etc all make a big difference.Personally,the cost of changing to EV s would be prohibitive.

Would be very interested to know if, when it was working 2nd time round, did it work, did it meet your expectations? Very few KZbin video on sunamp.

That's a shame. Was liking the idea of the Sunamp for hot water when I eventually lose the combi boiler as no Legionella cycles to worry about and in theory more efficient than a standard water tank. Does seem like there's a need for a pressure reducer (closing a valve 90% just reduces flow, does nothing for high static pressure, and would actually increase pressure cycling downstream). Looks like a different failure mode from last time at least.

Ripped out all Sunamp; have stuck with Mixergy for 6 years - FANTASTIC - works with Eddi , heats top to bottom

lucky dip bargain for 10 to 12 k , would be good for yards that store parts, batt pack must be worth a few bob

Maybe look at a heat store where the tank is the reverse of the normal design and a lot safer. Won't explode and take half your house out.

Well, JP, the problems of being an early adopter! My comiserations, sir.

Opening the valve, any amount will not reduce the resting pressure only the running pressure when there is demand on the unit. You need a special preasure reducing valve to do that. I have one to stop preasure knocking in my pipes when the loo has finished filling that got my pipes clatering.

You are now using your own broadband are u stupid.what happens if fault occurs?

It was always overpriced compared to a water cylinder, but its USP was the space saving nature of it. It's now much more expensive than LiFePO4 chemistry batteries per kWh of storage and you can use a battery for many more things. Ger rid.

Hi bud. Looks like a heat pump is the way to go for you guys?? Also, closing the valve won't reduce the pressure, only under flow. As soon as the flow stops the pressure will build up to equalise each side of the valve. Hope you get it sorted quickly 😔

Thanks for testing this JP, so we don’t have to.😢

I can't work out why this video and the comments are complimentary. Firstly they say the chargers are in groups A, B, C. They aren't. There is no such thing as A, B, C and according to the security guards there never has been. The chargers are numbered 1-80+, and you are allocated one, but there is nothing to stop anyone rocking up and plugging in. When I asked the guards they shrugged and said its a free for all, just plug in to any available charger. I was there on a reasonably busy weekend and at least half the chargers were unused, but see below. You plug in then go to the app to find your outlet in a long list of eighty reference numbers. Then you are only offered pay as you go, click to start. It immediately errors with no indication as to why. The supplier only keeps office hours and there is no support through the app. There is a secret answer which I'll let you in on. Leave the car unplugged. In the app go to your account settings and there is a tiny link to add funds. If you are happy to do this (I very nearly didn't) put say £10 into your account. Now go back to starting the charge, then plug in. The charger will start (in my case after again saying they're was an error but it continued anyway). It handshakes with the car then goes into standby waiting for 11.30pm. This is showing by the flashing blue lights around the socket turning solid blue. If it is flashing or turns red it isn't going to start. My wife counted and about three quatre of the cars attached to chargers had flashing blue, which I think means the owners hoped a charge would start that night but I doubt it would. Quite a few cars were parked in their spaces at a charger but not plugged in, I suspect they had understandably given up. They need to explain all of the above in the email, drop all references to groups of chargers, remove the app option to PAYG, explain you need a credit balance and put instructions on all the charger posts. I have my fingers crossed I get a charge tonight 😢

We did consider sunamp but could not find an installer. Ended up with a 210lt mixergy. Seems to work well enough and given you have batteries i qould not bother with any solar diverter. Let the mixergy keep the water hot and set it to heat on normal cycle. Ut will use cheap rate anyway plus just top up from batteries. If you uae solar diverter it turns a mixergy into a dumb mode or it did for us. Ours is working fine with a heat pump ....

Well this is disappointing! I'd finally managed to find someone who has a Sunamp and explained to me that these things *will* work straight off grid electricity. I was all decided that the Sunamp is the way to go for hot water and now you've made me doubt it. However from reading some of the knowledgeable sounding comments it could just be a case of yours nor being installed correctly...? 🤔 I'd have to watch that too because our water runs at high pressure. Anyway, I'm sorry youre all disappointed, hope you're able to make the suggestions made here and maybe try again...? Have a feeling youre done with it though! Will you be going for the Mixergy with its clever tech and economy or just a plain old immersion and be done with it? Hope you get to make the follow-up video soon.🤞👍

I nearly went down this route due to space but fortunately I found a tank that fitted the space, luckily?

2:30 reducing the valve will not reduce pressure, only flow rate

I'm looking at installing a Tepeo boiler which I believe uses similar technology? So it's a bit concerning hearing about the problems you are having.

Mine leaked too. Heat exchanger broke and filled my front room with water. Not a PCM leak 😒

The latest model (they superseded yours too) has an installation document that REQUIRES a pressure relief valve in the cold water pass through circuit. Something they previously crowed about as being a plus for the technology…….. Some plumbing will be needed if you decide to take another swap out.

My smart gas meter has not worked for 18 months, I was quoted £75 to change it, like I'm going to pay for a new meter to save the supplier money

Hey Jonathan - we have a solar thermal. Obviously it's much better in a hotter country like Portugal, but we love it. It's basically an immersion heater linked to a thermal solar panel(s). You can add a heating element to it - which surely could then work along with an eddy (although, if the un isn't shining then you don't have spare solar..... but you can use the overnight tariff, obviously). I must say, it doesn't have to be a hot day for it to work, but it does need direct sunshine. Maybe worth a gander if version 3 doesn't work!

JP. The valve you have restricted only reduces the flow. When there is no water flow the pressure either side of the valve is the same. You need a pressure reduction valve which moves to keep the down side at the set pressure. Roger C

What have Sunamp said

are you getting a regular unvented cylinder?

Did it really save you any energy in the long run I'm of the thinking we are just over complicating things all you need is a tank and an element
