    Hydronic floor heating system ideal for cold floor coverings

    Devex Systems

    Hydronic floor heating systems from Devex Systems have quite a sophisticated design which consists of the circulation of warm water through an intricate network of polyethylene oxygen resistant piping under a floor surface. This results in a gentle, warm heat distributed throughout the entire living space.

    This floor heating system is a great option for larger spaces, such as open entertaining areas. It works well under cold floor coverings like marble, stone, slate, polished concrete, and all varieties of tiles.

    A minimum area of between 60m² to 90m² is required for best results when running the system with a gas boiler. The water is warmed to 35-45ºC and circulated at a safe, low pressure through the durable pipes laid in or under the floor.

    Usually installed at the time of construction, the system remains turned on over the necessary season to provide a constant heat.

    Hydronic floor heating in screed: The pipes are laid on top of the slab and insulated in a sand/cement bed of at least 50mm deep. It is then covered by a suitable floor surface, such as marble.

    This way of using hydronic floor heating is generally faster acting than in slab system. Heating is controlled by using floor or air-sensing thermostats that regulate the flow of hot water through the pipes.

    Hydronic floor heating in slab: This system is a storage heating system. Hot water is pumped through the pipes laid in a concrete slab. Once the slab is heated through, it radiates the heat from the floor upwards, creating a comfortable and gently heated room.

    Floor and air-sensing thermostats are used with this system too. It is recommended that extruded polystyrene insulation beneath the slab and on exposed slab edges is used to minimise heat loss and ensure high energy efficiency and cost savings.

    Hydronic floor heating under battened timber: Pipes with this system are laid over insulation panels and sit directly beneath the floor boards. The pipes run in between the battens. Floor and air thermostats are typically set to 27ºC so as not to overheat the timber.

    These systems do require a level of maintenance with boilers needing regular servicing, which may also need to be replaced after 10-15 years. The pipes generally last a long time and the overall system's lifetime is similar to that of an electric floor heating system.

    Hydronic underfloor heating is very economical to run, however upfront costs are more than that of electric systems.
