Basic Functionality of Electric Underfloor Heating (EFH)

Electric Underfloor Heating (EFH) functions by transforming electrical energy into heat through a network of heated wires installed beneath your floor surface. It evenly disperses warmth across the floor, providing a gentle, encompassing heat that permeates the room from the ground up.

How EFH Works

When the system is activated, electric current flows through the heating wires, warming them up. The heat then rises from the floor, warming the room and objects within it. As the heat spreads uniformly across the floor, it avoids creating cold spots often associated with traditional radiators.

Types of EFH

EFH systems mainly come in two varieties: Electric Underfloor Heating Mats and Loose Wire Systems.

TypeDescriptionBest Used For
Electric Underfloor Heating MatsPre-spaced wires attached to a mesh mat. Easy to roll out and install, offering uniform heat distribution.Ideal for larger, regularly shaped rooms.
Loose Wire SystemsMore flexible, allowing wires to be positioned as needed. This offers greater coverage in irregularly shaped areas.Perfect for smaller or irregularly shaped rooms, or areas around obstacles like toilets or pillars.
