A St. Paul kitchen, fixed for good

Floor warming cable failed when a tile floor cracked. Floor joist heating under the subfloor fixed it, safely out of the way.

Rooms: Kitchen, dining room, hallway and bathroom
Replaced: Damaged floor warming cable and a 21-fin radiator system
Fix: Floor joist heating below the subfloor

Two-story stucco home in St. Paul with green trim — The St. Paul home.

The challenge

Homeowners in St. Paul were remodeling their kitchen and adding an addition, with floor warming cable under the new tile. Poor construction practices let the floor settle under the weight of the self-leveler and tile. It buckled and cracked, and the heating cable was damaged.

The fix

Premier Energy USA was brought in to assess the damage. The answer was ThermaRay floor joist heating: panels installed in the joist spaces below the subfloor, not in the floor itself.

Because the heat isn’t in the wear surface, there’s little chance of damage, and the flooring can be changed later without touching the heating system.

The result

After more than a year of remodeling and re-remodeling the kitchen, dining room, hallway and bathroom, the homeowner compares the new floor joist heat with her old 21-fin radiators in Part 3.
