Hi All: I am in the process of designing a radiant floor system for a home I am building in NW PA. I would like some suggestions on figuring out the heating loss calculation as well as the type of oil boiler and flexible tubing used. Your suggestions are most welcome. Thanks Joe [:D]

You can probably get heat loss calculations from the various suppliers of Radiant heat products. I did 2 installations. For the latest one I used an on demand water heater (LP) from Takagi. This is for the main hot water to the home and via a heat exchanger for the entire building. The building is a 2.5 car garage with a slab (I suggest 5 inch thick minimum)with a coachhouse/apartment above it. The foot print is 30 x 24 for a total of 1440 sq ft. The various suppliers will suggest the best setup for you.

Thanks Joe [:D] Maybe you want to think about Legalett -- only air in concrete floor with watercoil & fan . I installed two years ago & troublefree. You can run off household water heater. See their site www.legalett.ca They are Canadian as I am also but the design is Swedish with 27 years of experience. Let me know what you Think?
