We have old bar heaters on the walls in our scout hut. They aren't very efficient at distributing heat and I'm told they're not very cost efficient either.
DH has suggested I see if we might get a grant from somewhere to install some more environmentally friendly system but I confess tht I don't really know where to start looking. so, as always when I am at a loss, I've turned to Mumsnet 
Any ideas gratefully received.
TIA
