	RE: Defrost behaviours By RadWhisperer, 7 minutes ago Forum Air Source Heat Pumps (ASHPs)
	ASHP Model: Daikin Altherma 3M 4KW House loss: Calculated 3.3 at -3C, definitely overestimated though. Control mode: Weather Comp + Thermostat with room modulation +/- 4C adjustment to WDC Volumiser/b...
	RE: Grant Aerona: Is there a setting to keep the 2-port valve open during pump blockade By JamesPa, 26 minutes ago Forum Air Source Heat Pumps (ASHPs)
	Not unless either you allow the AI to turn on cooling when the sun is strong, or you give it control of the windows and curtains also! No amount of fiddling with heating controls alone will deal with ...
	RE: A2A vs A2W: Which Heat Pump Would You Pick? By JamesPa, 32 minutes ago Forum Air Source Heat Pumps (ASHPs)
	I have A2W. It works well. However ... If I had a modern, open plan low loss house then maybe A2A... except that such a house would probably already have UFH in place - in which case A2W without a d...
	RE: Grant Aerona: Is there a setting to keep the 2-port valve open during pump blockade By Unsure, 39 minutes ago Forum Air Source Heat Pumps (ASHPs)
	@grahamF Only the comments I've received from old school HVAC engineers in the states and nordic countries. There is a logic to what they're saying, but I'd be interested if any scientific evidence e...
	RE: A2A vs A2W: Which Heat Pump Would You Pick? By bornagain, 54 minutes ago Forum Air Source Heat Pumps (ASHPs)
	We have both. The advantage of A2A is a very rapid response and the ability to cool in the summer - our A2A is for the south facing rear of the house largely for summer cooling. Our house is very well...
	RE: A2A vs A2W: Which Heat Pump Would You Pick? By RadWhisperer, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	With existing rads it seems easier to just install A2W. I've seen some larger houses with multiple internal A2A units have pipework running all over the outside of the building which didn't look great...
	RE: Battery storage to run Heat Pump. By AgentGeorge, 4 hours ago Forum Energy Storage
	@jamespa I have 5kW PV and 5kW battery. By using the 8pus cheap rate and PV to charge the battery, for the months April thru October I averaged 98% on the cheap tariff, the battery was supporting the ...
	RE: Solis S6-EH1P8K-L-PLUS – Why I Chose It and What I’ve Learned So Far By Batpred, 8 hours ago Forum Energy Storage
	If you mean with Home Assistant, I have got a Solis modbus integration working. I did not check the frequency, what data are you after?
	RE: A2A vs A2W: Which Heat Pump Would You Pick? By Andrew J H, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	I think the main reason a2w is more popular in the uk is the grant. Long term, I think air to air will be more common, when the grant is removed for a2w I think the market could collapse for this unle...
	RE: Grant Aerona: Is there a setting to keep the 2-port valve open during pump blockade By GrahamF, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	@unsure you make an interesting point about longevity. Most of what I have read and heard says that compressors are worn out most by starting up and not by continuous running. Apparently, they are d...
	A2A vs A2W: Which Heat Pump Would You Pick? By Mars, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	It’s looking increasingly likely that air-to-air heat pumps (essentially AC units used for heating) may soon qualify for a £2,500 Boiler Upgrade Scheme grant. That means homeowners could soon have two...
	RE: Getting ready for export By Batpred, 11 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	Ok, my Solis can work to a huge variety of global grid standards. At the moment, it is working on G99, it is something that the engineers asked me early on to confirm before it connected to anything b...
