I don't defend mcs, I have gone on record as saying that it should be abolished or at a minimum stripped of its privileged position in planning law. ...
There is absolutely no challenge possible to the planning consent that's been correctly implemented so don't waste time. Its indeed very difficult to...
Heat pump efficiency declines quite markedly with low OAT, thats just the thermodynamics at work. The datasheets set it all out if you are interested...
Of course Im aware of that, I come across it every day. I presume that as the average is 18%, its rather more than 18% of the smaller values, and rat...
I can't see a way to get efficiency from the data. If you had flow rate and power in it could be calculated, but not what you have presented. ...
18% is a lot particularly if it's actually a fixed ish load thus more significant at low power outputs. Do you happen to know what happens if you ru...
There are several noise meter apps and one in particular for recording nuisance, which many local authorities will recommend you use. Can't remember ...
If your local authority approved it in a planning application (is that what you are saying) then it does not have to conform to mcs planning standards...

Absolutely so in principle. Whether there is sufficient incentive for manufacturers to develop sophisticated but easy to use controls of this kind on...
Its fairly easy to do, Ive done it on one radiator as a trial using off the shelf components only except for a couple of pieces of wood which I cut to...
