@sapper117 sounds good. Cheaper, warmer and most importantly a happy partner. Our wood and coal burners are now also nice to haves rather than th...
@cathoderay Do the Midea capacity figures include an allowance for defrosts? Mitsubishi's data includes this for its 2 deg C figures. In that link...
@cathoderay What I was getting at is that if your ASHP were performing according to the Midea specs then it would be close to meeting your requirem...
@markc Good results and looks like you made the right decision. Even allowing for the warmer November you're still using a lot less power. I did t...
@cathoderay are you sure it's an ASHP capacity problem? From what you say it can heat to a LWT of 46 C and has a RWT of 39C;that sounds reasonable...
I just set my stats to 30 degrees if I want to take them out the loop. That way they are always calling for heat leaving weather compensation to do i...
Alec, I know; I have monitoring and can see exactly how much energy the ASHP uses minute by minute. I'm just doing some experiments where I'm tryi...
Very timely question. I've already 'proved' (subject to the caveats @derek-m mentions) that weather compensation only uses less energy than a fixed f...
I think your flow temps look reasonable for ufh. Unless there is a fault, it would be very unlikely for an Ecodan to return a SCOP of close to 1. ...
@robl thanks, I think I totally misunderstood what a heat exchanger/PHE was. I think I do now. We don't have one and it seems to be fine without ...
I'm not sure I understand; are you saying if you have a PHE then water out is 5 deg less (or even 22 deg less) than water in? Where does all that ene...
