I have a new L-shaped (cavity wall - uninsulated) building comprising four
stables, a hayshed, a workshop and the last bit at one end (16 ft by 22 ft)
which will either be an office or a snooker room.
I want to have some sort of trickle heat in this office area (possibly
thermostated) just sufficient to keep damp away.
Does anyone have a sensible solution for me bearing in mind that electricity
costs are fairly high here?

Many thanks


Gerry
