Electric Underfloor Heating Running Costs

underfloor-heating-image

The running cost of electric underfloor heating depends on many factors, including the room size, the running time of the heat mat, as well as the insulation effect of the room.

The running costs have been based on a standard electricity price of 12.37p/kWh (ScottishPower,2019) https://www.ukpower.co.uk/home_energy/tariffs-per-unit-kwh

There is one more step to save costs - Placing insulation board

By placing a thin layer of thermal insulation underneath the heating mat, it can prevent heat loss downwards, which speeds up the warm-up time and minimises heat loss.

insulation board 2

XPS insulation boards are designed specifically for use with electric underfloor heating systems, very high compressive strength (30 tonnes / m2), lightweight, high efficiency, and low cost make this thermal board an ideal choice when fitting heating on to a poorly insulated concrete or screed base and works excellently with underfloor heating underwood and under tile systems. Insulation boards come with a 50-year warranty.

Thermal highly compressed boards
Size - 1200mm x 600mm (0.72m²)
Lightweight, high efficiency
Perfect for concrete or screeded floor
Suitable for evenly laid wooden floorboards
Available in 6mm and 10mm thickness
