It seems like the Favorite type of heating method is using some type of concrete to disperse the heat throughout. Besides concrete, what are some other successful heating techniques that you've done/seen?
Besides radiant flooring, we have directly used hot water in fan coils and fan convectors. Other established means are radiant wall panels and baseboards, but I have not directly used these. I've never done staple up either for that matter.
Concrete is less ideal due to its lack of quick response, it has a high thermal inertia. The best in my opinion is protruded aluminum right below tile or wood finish floors (Tile being better). You want a heat distribution system which uses the least temperatures to give the space the needed btus, and you want it to be low mass to respond quickly. Concrete is sometimes a compromise since it is much cheaper to install.
