I seem to have a few mental hang ups about temperature; for example

Perhaps you need to investigate proper temperature control if your
house can get too hot due to the CH being on.

I think that he was saying that is seems wasteful to heat the house at
night and then when it is warmed further by the sun in the morning, be
opening doors and windows to let the hot air out, when he could stay
warmer in the evening by wearing more and let the house warm up
naturally the next day.

I'd say it's always wasteful to heat the house at night.

Not when you stay up late and someone else gets up early.

And a decent system will compensate if it suddenly gets warm outside
during the morning.

The point is that keeping the house warm overnight or heating it up in
the morning seems wasteful if the sun does the job by itself later in
the morning.

Knowingb it's going to be warm at 10am, doesn't make you warm at 6.30am.

Quite - if the sun starts to warm up the house later in the morning, even
a simple system should accommodate for this. A weather compensated one
rather more efficiently.

We know that, but he was talkign about solar gain being so high that he
had to open windows. Then the argument becomes do you put up with a few
hours of cold or use fuel to heat the house just to get over those few
hours.
