A high efficiency boiler heats water and circulates through a network of the highest quality multitherm PE -RT polyethylene pipe, laid in the floor slab. This is a low temperature system which keeps running costs to a minimum.
Effectively, this system transforms your floor slab into a slow release heat radiator, heating every room equally with clean radiant heat. Hydronic sub-floor heating is ideal to run in conjunction with a Co2 Heat Pump System. In addition older existing Solar hot water rooftop systems can be harnessed as a pre-heater to the hydronic heating system, further cutting running costs and gas consumption.
As the required temperature for underfloor heating is quite low (approx 45o) this makes Hydronic slab heating ideal for integration with the gentle heat of a Solar Energy source. Rooftop solar hot water collectors used in conjunction with gas boosted boiler makes the system incredibly energy efficient with almost the entire energy requirement being supplied by the solar component with very little boosting required. This is particularly viable in the Australian climate. The start up costs are higher, but as the system operates more efficiently the pay back period is shorter that other solar power systems.
