How Does Underfloor Heating Work?
A series of winding pipes or electrical wires are placed underneath your floor finishing. Heat gradually releases upward, distributing evenly throughout rooms.
Dry System (Electric)
Electric wire systems offer easy installation but consume about three times more electricity than wet systems. Best suited for small, infrequently used rooms.
Wet System (Water)
Pipe-based systems circulating warm water require boiler or heat pump integration. Higher energy efficiency and more environmentally friendly but involve higher initial costs.
Retrofit
Underfloor heating can be installed in existing dwellings. Considerations include increased costs, flooring replacement, and compatibility with existing control systems.
