Great video. I had no idea this sort of system was available. I have radiant floor heating in my house and this would be great. Also, the SunAmp Heat Battery is very cool. Thanks for sharing this. I live in the U.S. so I will need to check if I can get this system here.
The Sunamp PCM melts at 58C, which means you have to supply water at 60+ Degree C to get enough heat transfer to melt it, and charge the unit. How is that more efficient than a thermal storage tank with a large coil.
Great video. I have a big house and I need at least 2 Althermas. Can they connect between themselves in parrallel with one master and the rest in slave mode?
Hi I have a 9 kw Daikan heat pump heating a 250m2 house and taking extremely long to heat and seriously expensive to run is this unit to small ?thank you
Hi Mark I’m not surprised it takes so long to heat up, sounds very under sized. Don’t know the spec of your house, but even a new build house of that size would require at least 11.5 kw, If your house is old and with cavity wall, loft and double glazing, it would 16kw. Go back to the installer and get them to check heat loss. The running cost will be high, because the heat pump is running flat out 24/7
I’m a little confused about this setup and how it works , my understanding of the sun amp battery that they just have over 1200ml of water , when activated they heat water to 60c and phase change over about 8-10 hours for heating or up to the packs kw rating for hot water. Not enough to heat more than two bathrooms at once , the air source heat pump without a cylinder effectively becomes less efficient digital combi . But the sun amp is just one pack I’m struggling to understand why it’s connected via the heat pump , being a phase change material it has to complete its cycle or suffers degradation to the containing material being electric connected it can recharge over ac in about an hour , to my understanding super heating the liquid in the pack has no effect on its recharge speed if anything would take longer and more energy not the 3 to 1 ratio heat pumps normally do. So unless the heat pump is doing the heating only I can’t see how just sun amp will be enough as it will be constantly cycling without fully discharging , withou the hot water cylinder it’s just not as flexible or efficient and a digital combi boiler and electric showers may have been a better option
Hi When the battery is less than 50% charged(so about 150 litres of water pulled through) The Heat pump recharges the battery for a 45 min period and than the electrical immersion heater in the battery takes over and completes the charge of the battery up to 65dc. The heat pump also does the underfloor heating directly. The sunamp is for hot water only.
@@ecobubl hmm still not quite clear , so being a b&b there’s normally more than 2 bathrooms and shower , with a typical water supply of 14 litres a min the sun pack will be depleted in a little over 10 mins with a average guest shower equalling the packs 150 litre heat capacity , with 45 mins to get back to normal that still leaves the possibility of the sun amp still charging or does it split the pack into two 6kw packs , or unable to provide heat so does the heat pump and digital combi that’s in the heat pump system Supplement the hot water feed they lost . I’m sure a small 100 litre tank could have been added in combination with the sun amp feed even if it was added under the kitchen sink as it is I’m struggling to see how this saves money granted all the houses heating demand are met , even so I just can’t see how 1 pack is enough, I know they can be stacked, but the calculations for a typical b&B hot water demand just don’t add up
@@ram64man No the Sunamp battery we installed holds 14kwhs of energy, that provides around 300 litres of water at 50dc from one charge. Once 50% depleted it starts recharging, so it can charge and discharge at the same time if required. This customer has never ran out of hot water.
All good when things work in lab environments. When there are only two engineers in the company who know the system to fix stuff when things go wrong. Not convinced at all.

what kind of material is used to do so? is something that is available in the market? thanks
Why not have a much bigger heat battery (80-100kWh) with a much smaller heatpump (5.5-7kW)?
Surely that’s a better combination?
Running cost of this system vs a cylinder one?
Let’s have cost installation and use?

Hi Mario
Many thanks for your comments, I`m not 100% sure about the master slave device, I would to confirm with Daikin.
@@ecobubl Thank you! I know other systems has a "cascade" combination
What is inside the Sunamp battery that makes possible to store heat?
Phase changing material
@@ecobubl is it possible to know the name of the PMC? is it toxic?
@@BurninVinyl I have no idea what the PCM is called, you would need to contact Sunamp for that.
@@ecobubl ok thanks anyway!
@@BurninVinyl It's actually just salt and vinegar! No toxicity at all.

Thank you for your reply yes a brand new house here in Ireland, A2 rated super insulated.
Are you using a lot of domestic hot water, because an A2 rated home in Ireland, far exceeds the current Part L Building Regs.
Lovely
What a lovely girl. I can't see this setup working in a B&B though.

It’s Daykin not Diekin 😤
I agree, many years ago as an air con engineer, we use to say “if you’re baking call Daykin” 🤣
