Benefits of Grant Underfloor Heating Systems
Opting for underfloor heating (UFH) from Grant brings a wide range of benefits:
-
Energy Efficiency: Operates at lower temperatures than radiators, saving energy.
-
Comfort: Delivers even warmth without hot or cold spots.
-
Aesthetics: Eliminates the need for radiators, freeing up wall space.
-
Silent Operation: No clanking pipes or noisy fans.
-
Zoning Options: Different areas can be heated to preferred temperatures.
With these benefits, underfloor heating is no longer a luxuryits a smart home upgrade.
How Underfloor Heating Works
Underfloor heating uses either water (hydronic) or electric elements beneath the floor to warm a room. Grant primarily focuses on wet systems, which circulate warm water through pipes embedded in the subfloor.
Components:
-
Pipework: Carries the warm water
-
Manifold: Distributes water flow
-
Insulation: Prevents heat loss
-
Floor covering: Tiles, wood, or laminate
This setup creates a large radiant surface, delivering gentle and efficient heat.
Types of Grant Underfloor Heating Available
Grant offers different systems depending on the build type:
| Type | Description | Best For |
|---|---|---|
| Screed System | Pipes laid into screed layer | New builds |
| Dry System | Pre-routed boards with pipes | Retrofits |
| Overlay Boards | Slimline design for low floor build-up | Existing floors, renovations |
| ONE UFH Packs | All-in-one solution including controls and pipes | DIY-friendly setups |
The right choice depends on your floor type, insulation, and heat source.
