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.

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.

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.

It doesn't store the heat chemically, it stores it as heat. Phase change materials still store heat as heat, so therefore must be insulated in the same way and the lose their heat to insulation losses the same way as hot water does. Phase change material only allows more heat to be stored (as heat) in a smaller area, but there's no chemistry here.

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.

I "lived aboard" a 42' Mathews cabin cruiser for over a decade through the '90s and solarvoltic wasn't worthwhile back then, we had a solar water heater on the roof and a very insulated hot water tank down in the engine space. it also was plumbed into the engines closed loop cooling system so anytime you had run the main engines you also had hot water. And many American RV buses and motorhomes also do heat recovery from the engine to the potable hot water tank

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

Great stuff. Have you looked at its compatibility with a thermodynamic heating panel system?

At scale it's even more advantageous for storing heat on heat networks as unlike a buffer tank, all the heat comes of at the same temperature rather than cooling as heat is taken off.

We have an older version, the Uniq, not the Thermino, but I imagine the principle is the same. Interesting to see it explained properly at last, rather than just the 'it works like a hand warmer' I got from the Fischer Future heat fitters. I'm still not quite sure though how it works with only cold water coming through it, as it is our only source of hot water, no immersion heater tank, so does it just use electricity to turn the pcm back to it's liquid form, ready for the next time water is needed heating?

Can you tell me more about the pressure relief valve?

We are on the Octopus Agile tariff which is working out about 45% cheaper than Economy 7 but atm I’m scheduling the charging of the battery manually using the Smart Life App. I would like to automate this process with something like the IFTTT but my smart switch doesn’t seem to be compatible. Any recommendations how to do this?

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 ?

How many inputs does one of these have? Could I connect an oil boiler, boiler stove and solar hot water together? It looks like an interesting idea that would be worth further research. Thanks

1.Great to see efixx going into home energy area. 2. How heavy are these? Could they be installed onto a wall like a boiler can?

Also something very interesting you forget to mention is tha the energy is stored individually from the environment .. what i mean is that if you store a hot water in a tank if its freezing cold outside it will loose its heat but this is independent from the environment you can have it in the snow for hours you will still have the heat once you triggered the reaction ... Even better you in a bigger scale you can store heat on summer and just trigger it months later to have heat on winter !! Well done guys

It’s not magic - you need heat to change the phase of the material in the first place. It can’t magically store it for months. It will change phase back as heat escapes and the temperature falls below the phase change point. That’s how it heats the cold water because the cold water triggers that phase change. If you have a heat pump you would need to add heat back in because releasing all that heat without cold water to absorb it would likely damage the unit. It’s efficient because it doesn’t require a lot of energy to maintain it above the phase change point.

As I understand they are not using up super saturated liquid (salt water) like the hand warmers do.They use paraffin wax. So it's not really a great example to use the hand warmer as a comparison. But paraffin wax holds twice as many joules per kilogram of heat vs water. They have simply designed a container for melted paraffin wax that is insulated like a hot water tank, and then they run exchangers through the paraffin to extract the heat into water as demand requires. If you leave the thermino for months without input heat the wax will eventually lose its heat and solidify, unlike a hand warmer.

Very good product

so this is kind of like a combi boiler (instantaneous hot water, not stored) but instead of gas its using stored energy which can come from either heat pump or electric? How long can it hold the heat? Eg could you heat up with off peak overnight electric and use through the following day? And can this run heating as well as hot water, or mainly for hot water only?

I would see that in Switzerland especially in 2nd houses (chalet) where you have a seperate system to do HW with a boiler doing 20 cycle of 20 to 75deg during the year for nothing. When you only need a pcm pluged to the main heater with the temperature around 50 deg.

What is the temperature, where the phase change happens? Does this fit to all kind of Heatpumps? Or is the Salt-Vinegar mixture actually adjusted to your individual system at home?

That's exactly right, it's essentially a storage heater with the added bonus that the phase change material makes it super effective as it can store more heat than water, which makes the unit smaller than a tank. 👍

How does it control the crystallisation process? If the design is similar to heat pads, once crystallisation starts, it can't be stopped. In which case, you would need to use all of the energy that it is storing immediately, else it would go to waste.

Not exactly apples to apples. So how good is the material and housing at retaining heat when idle and how much heat is is absorbed from the heat pump comparing the pump side inlet/outlet temperatures to a heat exchanger in a tank of water?

Hi, I'm looking into the alternatives for a new heating / hot water system and I want to get a setup that can cope with changes. I'm thinking of continuing with a gas boiler for now, as to install a heat pump would be too much of a financial commitment. I have been looking at the mixergy tank, but you can only get an indirect coil/ immersion tank in unvented form which could give me issues regarding pressure relief pipework. I'm sure Sunamp used to make more of charging it with heat from a gas boiler in the past but this is the most recent I have seen it mentioned. Would you plumb it the same as a cylinder if you can set a low temp at the boiler and would the signal back to the boiler work on capacity and not really temp. My short term aim would be to use cheap off-peak electric then gas as a backup , medium term PV, and then finally heat pump.

This would depend on the heat battery size, our nominal hot water rating for our heat batteries are:, Thermino 70 - 1.59gpm Thermino 150 - 3.96gpm Thermino 210 - 5.28gpm Thermino 300 - 6.6gpm

Hello Do you do any training course to be an approved installer in order to get maximum warranty for the unit Thank you

Good presentation. I have been looking at these for a while, thinking this could be an ideal solution to replace my gas boiler. Few questions I've had: 1) Could they replace my boiler for the central heating as well as heat my hot water? 2) Could I heat overnight from the grid on cheap energy as well as using my solar panels? 3) How cost efficient are they to run compared to a gas/electric boiler? 4) If I heated it up at night on cheap rate electricity could it heat my home all day? (obviously depends on size of house, how cold etc, but looking for some averages).

Imagine it as an electric hot water tank, just made smaller. The energy savings lie where you use a heat pump for the heat over the internal element. It's not really made to store enough heat to warm your entire home, more to buffer the requirements you have for heat. It would work alongside a heat pump or boiler (typically where you have large peak hot water demands), not ideal to replace them entirely.

In answer to your first question, yes - and our range for domestic space heating will be launched this year. The asnwer to your second question is also yes. In the Thermino ePV model, the solar power diverter can have a boost setting to allow the unit to charge overnight on a cheap tariff in addition to the PV demand.

how do you replace the salt when the salt is unchargeble?

Its standby power is 7W...it's like 2 LED bulbs switched on, what does it do when standing by, why 7W for standby? For the "e" models (mains electricity only models), does it need to use the full power for hours each day, or only need the power at the moment when the hot water taps are switched on?

What about if you have poor water pressure? Still need pumps?

Excellent video and very clear description, thank you. You mention using the heat battery for a shower or to wash up... could it be used to replace a gas combi boiler for central heating, i.e. hot-water radiators? Could it supply enough hot water to heat to run the central heating for 2-3 hours in the evening and morning? Thank you.

In short, no. The heat required to heat a large space far exceeds the capacity of any form of storage.

Great bit of kit. What sort of price are they though?

Don’t get much change from a £1000 - good to see you here Brian.

Hi, quick question. The data sheets state a 25l/min max draw off at 55 degC. If for argument sake I draw off at this rate this will give me 12 mins of 55 degC water but after this, does the temperature just degrade to a lower value? I know in reality a shower will be mixed down so this isn't a real life scenario but wanted to understand how it works. Also, from a reheat prespective how much energy is required to re-energise the phase change material? For a 300 L tank with reheat of 2hrs from 10-60 degC is 8.8kw (4.4kwh of direct electricity) what is the equivalent here? if my maths is out let me know but in priciple what is the comparison? If it can continually produce low grade heat after the initial discharge then this is very good; just thinking about a very busy house if people are having loads of showers if guests are around Thanks

it could easily be put on the roof near the solar panels. even a drain back heat collector to heat it, twice as efficient as PV panels, so half the size.

so, what volume of hot water is available from this? Enough to fill a bath for example?

How long until this system wears out? What is the max temperature it can work at ? how much heat loss in standby mode compared to a tank?

I'm just wondering what these corrosive salts and vinegar will do the pipes and fittings in the unit.

Sodium Acetate Trihydrate has little to no corrosion effect on the pipes.

How heavy are these units, do they arrive empty and we add water on installation?

The units are filled with a phase change material so arrive on site fully filled. This does make the units quite heavy compared to empty hot water cylinders.

Size 3 which is the one in the video weighs around 60kg the 6 is around 120kg the next size up will probably be in the 200 range

I'm always suspicious of new products, but this sounds a viable option to gas. However what is the life expectancy of this product and does it need regular servicing?

Hi guys. Greetings from The Netherlands. Forgive me for asking a typical Dutch question, but what are we looking at here price wise?

What is the price point and will it be available in the US?

Nice product, but from what I've researched, the PCM melts at 58C, for domestic hot water applications. If thats correct, then the battery won't charge off a standalone, low temperature, air-to-water heat pump. You'd need a high temp heat pump or a supplemental immersion heat source. Where's the operational cost benefit in that?

It has an immersion element built into it.

what is the unit cost vs equivalent 300l tank storage?, ignoring installation etc, just basically the cost of the unit...

love when they tout new devices but never give price nor comparisons to reg heat pump hybrid units or yopu can only get price from high pressure salesperson

Was this PHEX exhibition? Think I missed this one
