But surely that’s just the same as the heating coming on for a couple of hours? And more polluting, too.
Mine has come on a few times, for a couple of hours in total, in the last week. That’s for about half an hour on a few mornings and about half an hour for two or three evenings. It doesn’t seem to me to be more virtuous to light a fire in the evenings then to have the heating on for a short time.
