Heat Sources

Hydronic heating keeps running costs down by allowing a choice of energy sources, since the water can be heated by a range of energy efficient and environmentally friendly heat sources. Gas boilers are typically used, with other options including high efficiency electric heat pumps, geothermal heat pumps and solar energy.

High efficiency condensing boilers are also available and recommended as they have a higher efficiency than gas boilers and have far lower emissions. A condensing boiler recycles the heat that is typically lost in the exhaust of a non-condensing gas boiler. Additionally, much of the exhaust emissions are condensed and discharged into the sewer system. Condensing boilers typically have efficiencies of 95% or more compared with non-condensing gas boilers at around 70-80%.
