@derek-m - I will have another close look. The only other connection to the rad circuit is the connection to pressurise it (it is a closed system) and...
@derek-m - thanks, that would be very welcome, and I am sure others will welcome it too. All the rads have TRVs and they are all definitely open (th...
@ronin92 - I do have a multi-meter with a thermometer scale using a thermocouple to take the readings. Putting that inside the insulation foam pipe wr...

@editor - these stats are always fascinating. Or perhaps I should get out more often. A couple of quotes: "Since applications for grants opened for ...
Very informative. Unfortunately I was tied to using a Midea unit, by virtue of it being baked into the planning and listed building consents. The Mide...
Indeed it is, but it is currently summer, so no need for 16kW, plus I am wary of voiding my warranty because I have tinkered with the settings, hence ...
