Underfloor Heating Buying Guide


A heated floor solves a problem visible heating never quite does: cold spots. Rather than warming a room from one corner outward, underfloor heating spreads warmth evenly beneath the entire floor, and because the heating element sits below the surface rather than against a wall, it also keeps the room's overall look clean and uncluttered.

Why underfloor heating works so well

Even heat distribution means warmth radiates consistently from the floor across the whole room, removing the uneven pockets of cold a single radiator or wall heater often leaves behind.

Genuine energy efficiency comes from underfloor systems generally operating at lower temperatures than a traditional radiator while still achieving the same level of comfort, which can meaningfully reduce ongoing heating costs.

Health and hygiene benefits follow from the heating element being built into the floor rather than exposed as a radiator: with no visible unit collecting dust, underfloor heating tends to circulate less dust and fewer allergens through the room than a traditional heater might.

Genuine flexibility across different homes and rooms means underfloor heating can be installed as a single-room addition or as part of a whole-home heating system, tailored to the specific space and flooring type involved.

Brands in this collection

This collection includes underfloor heating systems from Thermogroup and Radiant, both offering genuinely reliable performance suited to a range of home renovation and new-build applications.

How does underfloor heating improve energy efficiency?

Underfloor heating systems generally operate at lower temperatures than traditional radiators, using less energy to achieve the same level of warmth, which can meaningfully reduce overall energy bills.

Is underfloor heating compatible with all types of flooring?

Yes. This collection's underfloor heating systems are compatible with a variety of flooring types, including tile and wood. Specific configurations are available to ensure the system is installed correctly for each flooring type.

Can underfloor heating be installed in existing homes?

Yes. Underfloor heating can be installed in both new builds and existing homes. For a renovation specifically, certain preparations may be needed to accommodate the system, and it's worth discussing this with the installation team during the planning stage.

What maintenance does underfloor heating require?

Underfloor heating systems are generally low-maintenance. Regular checks are worth doing to confirm optimal performance, but the systems themselves are designed for long-term reliability with minimal ongoing upkeep.

How do I choose the right underfloor heating system for my home?

Consider the size of the area to be heated, the flooring type involved, and the household's specific heating needs together. Getting guidance on these factors helps in selecting a system that delivers genuine comfort and efficiency for the specific space.

Completing the room

Underfloor heating is easiest to plan alongside the room's flooring choice, since compatibility and installation method both depend on that decision. The Blue Space's Tiles and Flooring collections are worth reviewing alongside an underfloor heating selection to plan the full room together.

Frequently Asked Questions

What is underfloor heating and is it worth it in Australian bathrooms?

Underfloor heating (also called in-floor or radiant floor heating) consists of electric heating elements or hydronic pipes installed beneath the floor tiles, warming the floor surface from below. In Australian bathrooms, electric mat underfloor heating is the most common type. It is particularly popular in cooler climates (Melbourne, Adelaide, Canberra, mountain regions) and in bathrooms with stone or porcelain tiles, which retain cold without heating.

What type of underfloor heating is best for a bathroom?

Electric mat underfloor heating is the most practical choice for Australian bathrooms. A heating mat (consisting of resistance cable pre-spaced on a fibreglass mesh) is embedded in the tile adhesive bed before tiles are laid. It is controlled by a thermostat with programmable timer. Hydronic (water-based) underfloor heating is also available but requires connection to a boiler system and is more cost-effective for whole-home installations rather than a single bathroom.

Does underfloor heating work under all types of bathroom tiles?

Electric underfloor heating works well under ceramic, porcelain, and natural stone tiles, materials with good thermal conductivity. It is generally not recommended under thick natural timber flooring or carpet. Always check the compatibility of your chosen floor covering with the underfloor heating system before purchasing.
