I’m building a new passive solar home.  My lender is requiring a heating system and doesn’t seem to keen on thinking the sun will do it (we will have a woodstove, too, but that doesn’t count for the lender).  My thought is to put in baseboard electric resistance heating with built in thermostats, since I don’t plan on using the system and it’s just to satisfy the lender.

Does anybody have a recommendation of how to size the system or where to go online to find information to size the system?  (I tried Google with various keywords, read a lot, but didn’t learn much)

Any other suggestions?
