Pipe-fitters installing hydronic underfloor heating system at construction site

Comfort Heat has now become one of the largest designer and supplier of hydronic underfloor heating systems in Australia. This means Comfort Heat can design and install heating to larger floor areas which is not only extremely comfortable, but energy efficient too. Hydronic heating keeps running costs down while allowing for the use of more environmentally friendly energy sources as alternatives to straight electricity also ideal for off-grid heating solutions.


Hydronic underfloor heating relies on pipes laid in the concrete slab or screed to carry heated water. The water can then be heated by various energy sources, the most efficient of which is a natural gas boiler. Other sources can also be used such as electric heat pumps, geothermal heat pumps, wood-fired stoves, and to a more limited extent, solar hot water systems.


Due to the plumbing infrastructure required, hydronic heating is more suitable for larger heated areas of at least 100m2. Alternatively, smaller areas could be cost effective if the energy requirements are incorporated into the entire project.

The hydronic heating pipe is installed in circuits of 100m which are then connected to a manifold. The manifold is used to supply the circuits with hot water and maintain constant water flow.

The total system is designed by qualified engineers to ensure the best possible outcome for any individual project. As the design and materials are crucial elements of a hydronic heating system, Comfort Heat can design and supply a complete hydronic system and ship it to anywhere in Australia.

Due to the nature of hydronic underfloor heating systems, we’ll need to discuss site specifications, metrics and related information to provide an accurate quote. Ask our technical experts for any help you need regarding these matters.

The Hydronic floor heating system can utilise a variety of heat sources. The most popular is a natural gas packaged boiler, however, solar evacuated tubes, heat pumps and wood stoves can also be used to heat the water  in the system.

Comfort Heat use a PEX pipe specially designed for floor heating. This pipe is multi layered and includes an oxygen barrier. The typical maximum pipe length is 100 M per circuit. The Circuits are installed in the concrete slab or cement screed with a coverage of at least 30mm from the top of the pipe (this usually means 50mm from top reinforcing mesh to finished slab surface). The pipes can be laid above the slab between battens with natural wood flooring, in a 50mm sand and cement screed bed or under the top reinforcing mesh in a screed if the 50mm cover is not possible.
