OK so if you are consuming 1300kWh per year that's about £300 at current electricity prices, less if you have an ashp-optimised tarrif. So you may fe...

Maybe, or maybe (depending on the system) you need a differential component also, which is why PID controllers are a thing. And maybe you want to tak...
... which is precisely how it achieves cost savings, by playing with LWT in response to OAT, predicted OAT, quite possibly predicted solar gain and wi...
OK got you. Thats how a buffer should, ideally, be run. I know of two basic techniques - 1. Adjust pump speeds (somehow) so the flow rates in an...
Adaptive, in this case, means a mode which adapts its behaviour, over a period of time (days), to the house (basically it learns about the house chara...
