| Thanks mark,
If i remember correctly, 20 thou sheet was about the maximum considered feasible. as it happens, i visited father today and he ha one of those radiant heaters so i checked the output with my hand.
I believe you can get the 'elements' so was considering a built in 'hinged' design.
Has anyone seen anything like this (it must be 20 years since i last looked at this)
