Buying Guide
What should I consider before installing radiant floor heating in a concrete slab?
- Room size and install area: Larger spaces may require more powerful systems or longer cable runs, while small baths can use mats or 40 sq ft kits.
- Floor covering compatibility: Most kits work under tile, laminate, and stone; always verify with underlayment recommendations and mortar requirements.
- Thermostat features: Look for 7- or 4-event programming, dual sensors (air and floor), GFCI protection, and safety locks for households with children.
- Safety and moisture considerations: Ensure CSA/CULus listings and wet-location safety to prevent issues in bathrooms or basements.
- Installation approach: Mats are easiest for rectangular rooms; cables offer flexibility for irregular shapes but require careful planning.
