Ideally, a furnace is matched for the size of the house, and matched
to the needs. It should run nearly all the time on the winter's
coldest days.

I've heard similar complaints about heat pumps that don't put out a
burst of heat but give even temperature control.

That's different though. A heat pump can't put out that much heat.
So I gather they run all the time when it's pretty cold, so I guess
they have to run the fan too.

An oil furnace can put out plenty of heat, and even if the temp rises
and falls, that don't bother me**. My main concern is if I can set
the fan to go on only when the furnace is running (not counting that
it starts late and stops late even now, based on I guess what hr said,
plenum temperature). I want to be able to do that.

Do furnaces with ECM allow that? Because there are still plenty of
oil furnaces sold that DON'T have ECM.

Thanks.

I can't ask the manufacturer easily because I haven't picked out
either a furnace company or a furnace, and some salesmen will just say
"Sure".

**The temp rise and fall is like a compresed version of the seasons!
