Hello all!
Trying to figure out which is the correct rating. Dan's Sunrad chart on his edr book are very different from the one on governale's site for their gov-ray line

even though they are identical in every dimension.
which one is correct i have to pull the trigger right away.
BAMN!

    Use Governale's. They may be a bit different on the inside.

    Thanks Steamhead. But when I do the math to heat a 10x13 room requiring approx. 1200btu Governale's site calls for only 3 sections. Working with 190 water temp and 2.25 sqft per section. Is that correct or am I doing something wrong?

    The other problem I'm having is getting a different btu rating from every site/tool that I've used. Even went to one local plumbing store and got a different rating and none of them match. Measured walls, accounted for window surface, outside walls etc.... Makes me very apprehensive, winter is around the corner and have much plumbing to do. Can someone help me figure this out?

    You need to do a heat-loss calculation on that room if you haven't already. If I were doing this, I'd do every room in the house, compare the heat loss to the actual radiation and determine the needed water temperature from that. Then I'd size the new unit based on that water temperature.
