The SUNAMP Hot Water Battery: What is it and How Does it Work?

Most plumbers don't even know this exists - The Sunamp is a revolutionary energy storage device for hot water systems. The Sunamp water heater is 4 times smaller than a conventional hot water cylinder.

This is a wonderfully helpful video. No music, no graphics, no annoying voice - just an intelligent guy explaining the system in terms anyone can understand. Thankyou.

You are an excellent presenter and spokesman for your company — very clear and comprehensive delivery without overwhelming your audience with jargon and complex concepts. And this is from a former technical writer.

That looks a good product. I work for a housing association and we have plenty of properties with heat pumps with cylinders. Quite a lot of them are bungalows with wet rooms. The large cylinders are only used for washing up and washing hands. A terrible waste of energy. This looks like an excellent solution. I'm a plumbing and heating engineer and think we have a long way to go to for heat pumps, whether ground source or air source to work as well or as cheaply as gas boilers. Especially in social housing. This is definitely heading in the right direction.

I do like the glass front showing off all the pipes inside. It’s like a piece of artwork. Absolutely amazing tech. Thank you for sharing this.

Very nice presentation, along with a very nice product. I have worked in industry over 40 yrs, with equip producing temp as low as -40
thru glass oven operating at 1270 deg. Can you imagine the wasted free energy, my crews have pissed out the window in that time frame.

Fantastic bit of kit, they should look at getting that into the marine industry too, excess heat from the engines stored for hot water onboard ... good to have finally met up with you guys

The one most important question is what does it cost over a conventional tank, their are loads of great energy devices out there but the cost makes them impartible.

[wesleyofficer]

That’s a really neat idea.
The ability to store actual heat in a chemical solution where it could then sit on a shelf for a long duration without loosing the stored energy because it is no longer simple heat in a tank, then all at once you can essentially press a button and the energy will change from chemical potential in waiting back into physical heat to be used/enjoyed.

It makes perfect sense why this is called a heat battery.

Would only take this over a traditional storage if it comes with the same showroom front plexiglas, that storage looks cool 💪

Heat batteries using something other than water are a good idea for saving space. You can only heat water to 100C, but there are plenty of other materials that will be happy at 500C. There are some interesting designs that just use large masses of sand.
The design of this system seems pretty innovative.

[ericbraun]

I'd like to know how many BTU's (or equivalent) are stored in the various sizes. That's really the only way to know if it will perform as needed.

[brackcycle]

That was really interesting, Its a phase changing heat store, Great We need inovations like this .. But More info would be useful.... what temperature does it melt at ? How hot must your heat pump run? How hot does it make the water ? Whats its life span ( small pipes fir up) ? Whats its cost (& that might be affordable as its only a heat exchanger, salt & vinegar). ?
With this the Heat Pump flow needs to be hotter than the melting point, & the melting point hotter than the hot water So here you have 2 "Hotters", If you have a normal cylinder, the Heat pump only needs to be hotter than the hot water, 1 "Hotter". Getting the heap pump flow as low as possible is best for COP. Thoughts ?

[sampleoffers]

Amazing. Real point about Legionella. Still seems like steam engine from light trickle on heated material, then feeding a chemistry battery remains option for house. For electric vehicles has to be applications too. Electricians must know immediately.

[chriss]

Lots and lots of questions asking about controllability of the PCM, for example when you turn a hot tap on..then off after a few seconds….does the reaction stop or does the unit discharge all its heat and then need a “re charge”. Pointedly, although this question keeps getting asked, neither Sunamp or eFixx have responded ( unless I have missed it ) ????

[anilgargsfo]

Fascinating. Once the pcm reaction starts, can it be stopped? Or all the hot water has to be consumed at one go?

[dzl]

That was really interesting, well presented and a clear explanation of an excellent product. I'm an energy assessor and this looks like it could be a game changer in the industry.

[stevemorrall]

I have a heat pump installed (in 2010) and am costing a replacement. The Thermino looks great and would definitely offer space saving over the 600 litre unvented tank currently installed. Our water is very hard - how does the Thermino cope with scaling? Also the current tank has two circuits, one for the underfloor heating and one for DHW. Do I need two Thermino units? Great presentation, much appreciated.

[sergiofernandez]

That looks like a great bit of technology.

[andrewmorgan]

We’ve installed a few, great piece of kit

[dumyjobby]

Ok this is extremely interesting. I'm a plumber and this seems to be a game changer
