Use a TRV to limit the temperature and turn it off completely in summer as
required.

What a splendiferous idea. I think I can mix that into the plan.

Although it doesn't appear to make sense to control from your
young son's room, if that is the cold side of the house then it is probably
the way to go (for the upstairs)

Why not? As you say, its the coldest bit. Also it's over the kitchen
so closer to the boiler for cable running.

1. 'cos it's a room not in use for 95% of the day.

2. 'cos (parental pride excepted) he'll be an ungrateful little **** and not
thank you for it :-)

3. At that age (or any other for that matter) he'll probably dick around with
the settings.

4. The next would be owner will not see the logic of the situation and
expect the control to be in the master bedroom.

That said it does seem to be the best on offer.

I presume part P precludes the controls from being bathroom based.
Shame.

Even if it doesn't, it's unlikely they'd last long in a humid environment. The
ones I have looked at preclude that kind of placement.

And the varying tempratures switching it off and on at odd times I
suppose. Shower on and windows closed or loo used and window open!

Good point.

Thanks for the ideas.
Welcome, let us know how it goes.
