First, the good news.  In spite of  title twenty four they are going to allow us to install the step warm floor as our primary heat source.  They said if we were doing new construction they wouldn't allow it, but since we're remodeling it was ok.  It still seems pretty arbitrary to me.

We're going to install ceiling fans for ventillation in the summer time, but I was wondering if it is helpful to have a fan that reverses for the winter months.   I know the radiant heat doesn't heat the air very efficiently, but we have high vaulted ceilings and i'm wondering if a fan blowing down would make any significant difference.

If I have step warmfloor under tile and I want to remove or change the tile, can this be accomplished without damaging the warmfloor product?

thanks in advance.

I'd be interested in hearing from anyone that is using Warmfloor in CA.  I'm starting on a remodel + and I want to use radiant heat, but the title 24 requirements say I can't use electric heat as a primary heat source.  I am upgrading insulation throughout the entire house + will put down a radiant barrier on the floor (slab on grade).

BTW, do you have any recommendations for radiant barriers?
