| finfly 1- the late Std Noise Snr was a heating engineer for thirty odd years and I don't remember our central heating boiler (as we call them in the UK) ever being on after April every year except for an hour a day for hot water. I don't remember him saying it had to stay on regularly because it was 'good practice'. My old man was a bloody good engineer and tight as get out, so if turning it off was less efficient or harmful to the mechanics of the system, he wouldn't have done it.
As for systems in the US however, I have no idea. |
