my 1998 gmc jimmy has no floor heat but i have defrost and ven heat

the heat blows out the defrost when it should blow out floor vents only

it depends of your house. if it has more than one floor then it might not. it also depends on how many rooms has radiant floor

Radiant floor heat is considered by many to be better than central heat because it is much better for our environment. Another reason is that is cost less to heat your house using radiant floor heat than central heating.

The floor you can install on top of the radiant heat is Tile and hardwood floor.
