Radiator Advice

[Profpointy]

Apart from using the word radiate, it was quite right.

You appear to have missed the fact that they were talking about the radiators holding heat for quite a while after the boiler is turned off. Not about them being hot while the system is running.

That still doesn't make sense. Think about it for a minute. If the radiator is at a certain temperature it is tansfering heat to the air in proportion to the temperature difference.

Admittedly they will stay hot longer and indeed continue to give out heat for longer if they have greater heat capicity (essentially volume) for a given surface area, but I don't think you were saying that. You seemed to suggesting they were somehow tranferring heat slower which isn't the case, but I concede I may have misunderstood what you said

my "radiation" point was merely a pedantic quibble, more or less in fun, and beside the point.
