When we move house we have so little space for a big cylinder, I’m seriously considering one of these. Seeing how good Sunamp’s support has been is especially encouraging.
Hello Johnathan, if you are going to check the pressure in the expansion vessel you must first depressurise the cold water side. Also as the vessel is so small when you remove your pump valve you are loosing a lot of pressure in the vessel. You are best using a traditional dial type gauge to gradually release excess pressure to the correct value. (Use your pump to fill to approx 3 bar then slowly decrease using dial gauge)🙂
Greetings Jonathan, I had a Thermino 300e installed at my residence in the US this past April and you're videos have helped me on my journey. I'm glad your issues have been sorted out and look forward to your future videos. During summer months I've observed the Thermino's daily average of 3kWh and expect to see around 6kWh during winter months, and I'm curious what you've observed. Many thanks!
If you read the Sunamp installation instructions - they don;t REQUIRE those mods, so don't necessarily blame your installer. Also bear in mind that they max out a heat pump and run it far less efficiently than a DHW cylinder when they charge it. - It's called thermodynamics...
That new "pressure vessel failure overflow pipe" is too long/close to the floor. If you did have a failure in winter then you will most likely get icing which will then prevent the whole reason for being there. Either cut it shorter so there is space to flow out or perhaps extend it to the drain I saw installed. Oh and you really should have some insulation around it.
Interesting. I had no pressure relief valve on my install. Heat exchanger cracked and filled my front room up with water 🤔 i was happy with the technology otherwise.
If you have a heat pump and a hot water cylinder then it is cheaper for hot water as the COP of a Sunamp is 1.0 compared with heat pump COP 3-4. The advantage of the Sunamp is that is it very compact. If you currently have a combi boiler then you may not have room for a cylinder. If you are changing from a combi to a heat pump however, I think you need a hot water cylinder heated by the heat pump to qualify for gov subsidy. Having a Sunamp in this case may void your subsidy ( maybe there is a model of Sunamp which does qualify ?) I have a very early model from Sunamp to complement my combi as it allows my Solar PV to provide free hot water March-October without the need for gas and we don't have room for a hot water tank. It gave me some grief the first 2 years until Ivan and his mate came from Sunamp in Edinburgh to fix it and it has worked fine since then. If it keep s going another 3 years I may get another newer model at some stage.
@@Birko64 I think Sunamp do a version that works with heat pumps so you get the advantage of the COP - they did a project with Kensa Heat pumps in a block of flats - it’s on their website
how many kWh does it take to load the sunamp to full capacity ? and if I use cheap rate during those times then it should not have any loss of heat from the water as its on demand from the sunamp right ?
Hard to tell as the Sunamp only has indicator lights and no control app. Then Kw depends on HP or electric. Based on my usage when I was heating with an Eddie, I'd say I used around 2KW to charge at 150 to full from under 50%.
Jonathan, I'm curious why you opted for a Sunamp heat battery rather than a Heat Pump? I'm looking at replacing my gas boiler so am interested in the alternatives? I did look at a Tepeo boiler which I think is similar technology to Sunamp? But couldn't see any advantage over a Heat Pump?
Hi Malcolm, I’m sure Jonathan will give you his answer. From my understanding the Sunamp is best used just for your DHW as opposed to central heating. I looked at heat pump hot water tanks but was put off by the requirement for an annual inspection (at what call-out cost - £80?). The Sunamp is maintenance free, I’ve just got the e version but it charges in the cheapest Octopus Agile slots eg. Tomorrow the prices are negative between 1330-1430! Another advantage is their compact size so if you’re going from a combo boiler but don’t want to lose a whole cupboard to put in a water tank - Sunamp battery will only take up half a cupboard. Definitely worth a look at - hope this helps
Hi Malcolm. The Sunamp Thermino uses thermal storage to be a really space efficient replacement for a DHW cylinder. It is ideal for diverting excess solar generation, and as is based on a phase change material storing latent heat. The tepeo ZEB applies the approach of thermal storage to space heating, but using a solid, high-density material as its thermal store, and storing sensible heat with a much higher capacity than the Thermino. The main advantage of a ZEB over a heat pump is in the installation, where a ZEB can be connected to the existing radiators and pipework, while a heat pump installation generally requires much more disruption.
Probably due to your 12.4K followers and the fact you have had several other failures that you got a rapid response. How would a non-youtuber go on I wonder?

That's great kudos to sunamp for fixing and finding the root cause
In this instance the problem is the manufacturers installation instruction, not the installer in this case. (read them!)
Ah, this explains what those valves on my system does. Glad to have them. I also note that my pressure vessel is the size of a football.
Thank you for posting the update.
Hi Johnathan, that’s very reassuring - I think my installer has done everything correctly, so I’m very happy.

Sounds like a must have then , a relief valve
@@JonathanPorterfield Would have been such a relief had i had one 🤣
Hi. I want to buy the 210 litter sunamp. I have sollar panels. I dont know which model to buy? Any advice. Thanks
So it looks like its best to actually get Sunamp to fit it rather than any old plumber...🤔
It was a large electric contractor here in Orkney , they should stay away from plumbling !

I have the Valliant version of the Thermino. Was getting a COP of around 4.5 for 70C hot water to charge the Sunamp this spring/summer.
how many kWh does it take to load the sunamp to full capacity ? and if I use cheap rate during those times then it should not have any loss of heat from the water as its on demand from the sunamp right ?

Ive a heat pump already for my heating , the sunamp is instead of a hot water cylinder.

Yes that is the trouble with electric water heating: who you gonna call? Plumber, electrician or Ghostbusters?!😂
👍🤣🤣🤣🤣

...another sunamp customer here in Orkney also had a failure , they sorted her out just as quick 😉👏
The SunAmp is massively overpriced.
