Heating system for small addition.
Hi,
We’re (I’m) thinking about a small addition on the end of the house – basic “push out” – bring the roof out 14′, put some exterior walls, windows & a door underneath, etc. Very basic, no plumbing, probably 220 for possible future needs, a few wall outlets – a simple room addition to a very small bedroom.
The entire (ranch) house has in-floor heating – gypcrete & water pipes. My question is this: what type of heating should we (I) consider for this new room, which will be about 12 x 14? We (yes, we) really like our in-floor heating, but continuing the same gypcrete system could be more spendy that we can handle. I’m thinking more along the lines of the “gridwork” radiant system wherein the grid panels are laid on top of sub flooring and under the final flooring and the heat would have its own thermostat.
I’d appreciate any thoughts/suggestions on this. Also, if you have particular product, I’d welcome recommendations.
Thanks!

If the existing hydronic heat system has a little extra capacity you may be able to tie into it for very little money if you don't mind the new space operating off the thermastat for the existing room. If you want to make the new room a separate zone it gets slightly more expensive depending on how it's set up, but it could be very inexpensive.
Instead of gypcrete, if the new addition is easy to build fairly stout, normal concrete can also be used, it's just heavier. For a ranch, a slab on grade addition is often the least cost and a perfect place for cheap radiant heat.
Good luck
