Enjoy cozy warm floors with slab heating, an energy-efficient heating option for your home, shop or business. Radiant in-floor slab heating can reduce your heating cost by 30%.
Slab heating works from the ground up - literally! Heating components are installed below your concrete slab. Heat radiates from the floor, providing even heat wherever you need it. You’ll always have warm floors - and warm feet!

Runestone Electric Association’s slab heating options include:
- Boiler/hydronic heating, or in-floor water tubing. Water is heated electrically and circulates through flexible tubes installed in sand, soil or your concrete slab.
- Electric heating panels installed in soil or sand under a concrete slab building foundation. The ground underneath becomes an efficient, large mass of thermal energy that is only released when the area above it becomes cool so there is no wasted energy.
Slab heat is adaptable for all floor coverings - vinyl, marble, tile, carpet, wood - a slab heating system works with your interior decorating plans.
