My property is 200sq m. Two MCS surveys each taking 3hrs came out at 16kW. They ignored fabric upgrades I told them about and double counted room to...
As an example I checked the specs for the 6kW R32 (medium temp) and R290 (HT) Ecodans. They have the same claimed scop at 55C. Obviously there wil...
This is an interesting statement. It suggests your current total emitter capacity is well in excess of demand. So by switching on more emitters you ...

Which model Samsung. if its an older one and the max FT is 55, which is quite possible, then its equally possible that the DHW is limited to 55-5=50....
Nothing wrong with a bit of thermal mass unless you want to keep varying the indoor temperature, which is not generally how you aim to run a heat pump...
Maybe. Radiators can 'start off' well oversized, particularly if the fabric has been improved (although that appears not to be the case here). We ne...
Not sure where to start with this so I will start with basics. Apologies if you already know this. Heat pumps work best at the lowest possible ...
