Installation methods

There are many ways to use radiant heating and cooling. Here are some of the more common methods.

1. Slabs on grade: a highly efficient method with very high heat output (50-90 BTU per hour per square feet)




2. Suspended slabs: a slab is cast over floor joists. This is a way to gain high performance with a joisted floor.(50-90 BTU per hour per square feet)


3. Topping slabs: a slab containing heating tube is cast over an existing  slab. (50-90 BTU per hour per square feet)


4. Within joisted floors: Tubing is stapled to the underside of the floor from beneath. (up to 45 BTU per hour per square feet)

5. Ceiling: tubing is placed between strapping underneath the ceiling. (40-50 BTU per hour per square feet)


6. Ledger: Tubing is placed upon a ledge within the joist space. This is a common retrofit solution when building up to the floor is not practical.


7. Between Strapping: Tubing is placed in the space between wooden strapping members. If the space is filled with concrete or drymix the method offers most of the performance of slabs, and yet allows wooden flooring to be placed on top. A good way to heat a great room with high heat requirements. (50-80 BTU per hour per square feet).


8. Within the subfloor: The subfloor is precut or notched to accommodate the tubing. Another possibility if the floor level cannot be raised. (up to 40 BTU per hour per square feet)


9. Within the walls: Tubing is placed within the cavity of the partition wall. Exceptional comfort results if the floor and walls are heated in a bathroom. Combine wall heating with towel warmers. (50-80 BTU per hour per square feet)
