In-Floor Radiant Heat for Mudroom
I’m looking at a small (8’x10′) mudroom addition to my house in Ontario, Canada (Zone 6). I’ve settled on a slab on grade with a frostwall, The addition will be inside the heated zone, opening to the stairs down to my basement.
My house is 70 years old and heated by hot water radiators and I don’t want to get into adding a loop, and the mudroom would be basement temperature, not living space temperature, I think I’ve settled on electric radiant heat in the floor. Other than being open to the basement, this would be the only heating of this mudroom. I imagine it being set to a low constant temperature to keep floors dry, snow melted, etc. There’s an interior door that will remain which separates it from the rest of the house.
I’ve read that slabs tend to act as a heat sink, but I see this almost as a feature, as it seems this would regulate the temperature as kids are running in/out and bringing snow in. I have 2″ GPS to go under/around the slab to minimize losses to the ground.
Just curious if I’m way off base, or if there are better options for such a small addition.
