Re: Air Source Heat Pump Cylinders - new, hybrid techology, MCS pending. Your though
It makes sense if possible, (and if permitted..) it will take a while though.
Giona are an Italian company and I guess they are not actually concerned about MCS / RHI - their target will be new build - the market place is larger.
A normal A2W ASHP goes Air to Refrigerant (Evaporator) , Refrigerant to Water (Condenser) , Water to DHW Water (HEX), if you can cut out the last stage and just go refrigerant (condenser) to DHW it makes sense and will be more efficient (saves a HEX and a pump etc etc) - It's not actually new technology, it's just a different way of doing it.
The energenie (love em / hate em not up for debate here..) has a similar cylinder, i.e. puts the condenser inside the DHW cylinder - it just goes refrigerant to DHW water
In principal it could be MCS/RHI approved, though it will not be eligible for RHI for a while as it will take them 6 - 9 months minimum to work with MCS and come up with a standard.
The current ASHP standard assumes primary use is space heating, and "ignores" the inefficiencies in heating DHW, for the same reasons that as you don't get deducted for Solar Thermal.
The challenge will be measuring its real COP/SPF, based on A-5/W65, as current ASHP's are only rated A7/W35 and heating the real info (A0,A-5,A-15/W45,W50) out of them can be like getting blood out of a stone sometimes (hence the MCS SPF's)...
They claim a headline COP of 2.98 yet don't state Incoming Air Temp or outgoing Water / detailed heat rise information, so at the moment, the information isn't compliant.
They also have an MCS Logo on their website, though it isn't (yet) listed in the MCS product database.
I think it is a good idea, and could well work for some people.
Though don't guarantee it will ever qualify for RHI even if MCS Approved - they are TWO DIFFERENT things as some other ASHP and Biomass boiler manufacturers recently found out when the RHI applications were rejected.
Just need to bear in mind the ducting needed for the air !!
Would be interesting to see the BSI / WRAS certification because of the (small) possibility of refrigerant leak into the DHW.
