Hi.
At this time of the year the weather is not so cold and there for I am not using the Cantrell heating to heat my flat. The only room that I would like to have the radiator in is the bathroom (to dry towels on) and I can't install electric towel heater. I turn all the radiators off and just left the bathroom one open, lower to boiler (combi) radiator output to about 60. And set it to timer for 2 hours in the morning and 3 hours in the evening. The room thermostat is not playing any function because the rest of the house temperature is not changing.
My question. Is it bad for the boiler to run only on one radiator? The boiler is firing every 3 min for about 15 sec. In a month time the weather will get much hotter and than I will not use the heating at all so it's not going to be for long period of tome.
