Hmm. How much power can you get?
I am semi seriously considering this to do the 'wee small hours' winter
UFH heating.
And how much do they cost, and what amperage do they need to run..and
how do you switch them on and off..bloody great 50A Triac?
Although my total heating requirements are allegedly 10Kw, I dont think
the actual UFH could absorb much more than 5Kw without overheating the
screed.
I could run the boiler and the immersion of a switched circuit maybe..
