Under the floor the original and most popular configuration radiant floor heating is the industry standard for several reasons.
Walls floors and ceilings blank heat.
From the floor first and all areas under windows.
The heat ducts usually travel in the walls behind the drywall and exit through openings in the ceiling on first floor levels.
Commercial diffusers are ceiling mounted and used as supply air outlets.
For homeowners wanting to keep their existing tile or hardwood floor but still benefit from radiant heat wall and ceiling applications can be installed less intrusively and for a lower cost.
Radiant walls and ceilings lend themselves to remodelling since we don t have to disturb anything on or under the floor.
You can find floor registers in a variety of materials styles and finishes so you can incorporate them as a decorative element that also blends.
First heating from below creates a more active air current than in wall or ceiling options.
Just as the overhead rays of the sun are absorbed by the beach sand radiant ceilings warm the floor.
Baseboard mounted grilles are used as return air inlets to ducts.
Under normal conditions neither radiant floors or radiant ceilings heat the air to an uncomfortable level like in forced air systems however.
Ceiling duct openings work in opposition to the general law of physics that heat rises.
Make sure the outside walls are insulated according to code usually r 19.
As hot air rises away.
Also if the homeowners later decide to put carpeting on the floor it won t affect the performance of the heating system like it would have if the tubing had been in the floor.
For typical heat losses the bottom half of two walls of a room are usually sufficient.
If there is insufficient outside wall space to meet the heat load use interior walls.
Then it moves along floor joists to any upper levels.
Use only the bottom half of the walls 4 ft.
Baseboard registers also supply heated or cooled air to a room.
Registers these typically slatted covers are found in the floor wall or ceiling and their defining feature is a lever that allows you to open or close the air vent to adjust airflow into the space.
