Thanks Mark, I thought they must be close in size  ...  but the smaller 3kW one is still marginally different to the 2kW one you showed. See pix on bottom of page 5 of this thread  ...  it has a 100mm hole and is 70mm high.   Quote   Re shed heating, I got one of these for my shed, bloody ripper, very efficient. When it's cold you most likely wont have gobs of solar. Wow, can't argue about the price. How efficient are they, how long do they run on a tank  ...  and how much smell? My enclosed workshop is more like a normal room, vinyl floor and all  ...  and well insulated, but I could see one being very handy when I'm in the big shed or we're all out under the patio.   Quote   With the polyurethane I put in the cores, the way I figure is that still air is a very good insulator, that's why you have spaced windows, and insulation traps still pockets of air. Moving air has wind chill factor, BUT when each layer of wire is wrapped in the clear tape what have we done? Made still pockets of trapped air. Having the epoxy some do will certainly help, and the clear tape will conform to the wire to a great degree, but I figured having a big connected blob would transfer well, and I really do think it does. BUT I'm the only one that does it, so that might tell you something as well.     Yep, can't argue with any of that. I think the actual real life experiences are where the value is  ...  we can theorise all day and still end up all wrong or all right  ...  and your method clearly is working ok. I think I backpedalled on any coating because of the difficulty in unwinding if something goes wrong. I guess time will tell.
