I understand that A2A heat pumps have better turndown than A2W thus sizing is less critical. I haven't seen the proof that this is true however.
I don't think that ot is necessarily the case that you buy a HT pump for it's HT capability or that the expectation is to run a HT pump at ht. Manu...
It's questionable whether zoning saves money with a heat pump. The saving in lost energy is quite small, and because you need a higher ft as a result...
Thats precisely the same conclusion as I have reached. I have challenged MCS on the method they promote. Their response was that they are aware of...
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 ...
I'm not sure that's strictly true. What is true is that its more expensive to run a heat pump at a higher flow temp than at a lower flow temperature,...
I lived in Cambridge for a while. That wind from Siberia really got to me.
Exactly. Hall, stairs and landing are just another room, like any other.
As you say that will almost certainly be the case with an 'older' (low or medium temp) Samsung model, but possibly not with the HT models. Vaillant,...
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....
