@chandykris Yes, if you are able to last the day on solar/battery then Go is going to work out better than Cosy. Obviously the trick is timing the swi...
That's largely where I am, with a 12kW Samsung unit and on our coldest day last January with produced 96kWh of heat, so an implied heat loss of ~4kW. ...
Right, got you.
@transparent I have an Emlite ECA2 MID-approved meter fitted which records solar generation (available for around £40). The meter records slightly hig...
Agree with the above. Without knowing what the modulation curve of any given heat pump/compressor looks like, about all we can do is assume the manufa...
@heatgeek I have a very over-sized Samsung (12kW gen6, with a heat loss of maybe 4-5kW). We suffer with poor dT which struggles to get above 3C. Are y...
Yes, that's the default value, but can be set between 10C to 35C.
@bontwoody on my gen6 Samsung it's FSV #4013 Heating Off Temp, and by default is set to OAT of 35C (I have reduced mine to 25C). Like @ashp-bobba says...

Our March generation was 133% of our PVGIS prediction at 400kWh generated versus 300kWh predicted from our south facing 3.645kWp array. Now winter i...
As @bontwoody says, if they are inside the heated envelope of the house then it becomes a question of whether it is more beneficial for more of the he...
