Thermal mass is sustainable for heating because dense materials (like concrete, brick, stone) absorb and store heat well, acting as a "thermal battery," then slowly releasing that stored warmth at as temperatures drop, naturally reducing the need for active heating and smoothing out temperature swings.

Materials like timber and carpet do not absorb and store heat well and are said to have low thermal mass.

Hydronic underfloor heating is hot water in pipes and electric underfloor heating is an electric heating element. The hot water in a hydronic system can be heated by a range of heat sources, i.e gas or electric heat pump. Electric heating cable uses electricity.

Hydronic underfloor heating is typically installed in larger areas of 80 m² or more. While hydronic systems have higher upfront installation costs, they are generally more economical to run over time.

Electric underfloor heating is best suited to small and medium-sized areas, renovations, and especially bathrooms.

Hydronic, heat pump, in slab underfloor heating is one of the most economical underfloor heating systems available.

Concrete slabs offer excellent thermal storage, allowing the system to be heated during periods of high solar generation or off-peak energy times, then gradually releasing warmth over extended periods.

Thermal mass refers to a material’s ability to absorb, store, and slowly release heat, helping to maintain stable indoor temperatures while reducing energy demand.

Yes and an excellent choice!

Underfloor heating provides a safe, comfortable and energy-efficient way to heat your home.

By delivering warmth from the ground up, it works in harmony with the natural principle that warm air rises, creating even, silent, and consistent comfort throughout the space.

Hydronic underfloor heating powered by heat pump technology represents the future of sustainable home heating, supporting a low-carbon, net-zero built environment.
