Red face heating/insulation

We have just completed a small porch that I would like to insulate and heat. The porch is 7x12 with lots of glass. I was thinking of R-19 for under the porch it's pretty much open there, R-15 for the walls because of 2x4 and R-25
for the ceiling. I was also thinking of a electric wall heater maybe 2000 watts but don't know if I'm better with 2 1000 watts and if I should go to 220 instead of 110. Any suggestions?

It's a PORCH!! By definition, that is NON-CONDITIONED space. That means you can't heat or cool it.

On the other hand, if you DO want to heat and cool it, it becomes LIVING SPACE. In that case, you probably have way to many windows in such a small space to meet energy calculations!!

You haven't told us where you are, but what I just told you is based on CA codes and requirements.

Red face

Thanks for the reply Lefty

Actually I live in Mass this is only a three season porch with the heat to be used on coolish nights for a short period of time. So I'll take all the help I can get.

Again Thanks
