Hydronic Heating

Modern Comfort Heating with Low Running Costs


Hydronic underfloor heating is an energy-efficient and sustainable heating solution and provides your home with comfortable warmth through the winter months.

Hydronic floor heating is a great option for large, open entertaining areas. This system is an attractive and often requested upgrade for a wide range of applications, especially when paired with an efficient condensing natural gas boiler. It works well under several floor surfaces including marble, stone, slate, carpet, timber and a varieties of tiles.

The system can be zoned to ensure low running costs and user flexibility. Our Technical Team will provide you a customised design to suit your needs.



“Hydronic floor heating is a radiant heating system that results in low air movement compared with convection systems like ducted heating and air conditioning. This means very low levels of dust movement – a great relief for allergy and asthma sufferers.”


“Hydronic floor heating is a very economical way to warm your home, especially when compared to traditional systems such as air conditioning. Hydronic floor heating provides a radiant heat that is especially comfortable compared to convection heating.”


“Our hydronic floor heating systems have the longest available warranties with the piping systems being under warranty for 25 years! A regular service of the system once per year will ensure that you get the most from your hydronic installation. Most people choose to do this as the weather begins to cool.”


Hydronic floor heating is a great option for large, open entertaining areas. It works well under cold floor coverings such as marble, stone, slate, polished concrete, and all varieties of tiles. It may also be used under carpet and timber floors. We recommend inquiring with timber manufacturers before the installation, which we can help facilitate.


Hydronic underfloor heating is ideal for areas with a combined surface of over 60m2. Lounges and open-plan concepts are perfect for hydronic underfloor heating. Hydronic floor heating is installed in the following systems: in-screed or in-slab for various hard type floorings like tile and concrete and diffusion plates for under battened timber floors.

An in-screed system is a dynamic system that allows the user to make adjustments to the temperature relatively quickly, especially when combined with insulation. An in-slab hydronic floor heating system is a ‘set and forget style system. As the pipework is in the slab, it will heat the entire slab and create a thermal mass that holds the heat. This essentially makes it a storage system that holds the heat for a long period of time so even when the system is switched off, it will take time for the heat to dissipate.
Whether you are contemplating a renovation or including hydronic underfloor heating for your new home, below is a guide that will help to determine your ideal installation for your floor covering type.

PE- Xa pipe with EVOH Oxygen Barrier   

X Pipe and Blansol pipes are crossed linked-polyethelyne pipes with EVOH Oxygen Barrier. They are purpose made hydronic heating pipes constructed with an EVOH oxygen barrier outer layer, and adhesive layer and a PE-Xa inner layer. Cross-linked polyethylene pipes are well suited to hydronic heating operations due to their temperature tolerance and flexibility making them easy to install. The Cross-linking gives polyethylene a high resistance to both pressure and temperature.

  • 15 Years Warranty (Highest and Longest in class)
  • Multiple fittings available and covered under warranty

Multilayer Hydronic Heating Pipe   

Multipex Pipe by Blansol is a multi-layered heating pipe that is designed for use in hydronic heating systems. It consists of a butt-welded aluminium core with an inner and outer layer made of cross linked PE-Xa. The three layers are bonded together with adhesive layers. This combination of materials makes the Blansol Multiplex pipe highly durable, flexible, and resistant to corrosion and chemical damage, It is also capable of handling high temeratures and pressures, making it ideal fo use in a variety of heating applications.
