Hydronic heating systems are becoming very popular in Australian homes. They use a boiler to heat water, pump it around to under floor coils or wall mounted panels and then radiate the heat outwards. They typically run on gas so have all the advantages of a gas heater except the heat is radiant, meaning energy from source to object like the sun, and it heats very evenly leaving no hot or cold zones.
Comfort- sales of hydronic heating systems have increased significantly in recent. Australians are catching onto the benefits. Heat is distributed evenly, you do not get bad smells like you can from gas heaters or ducted systems and they’re not draughty because they’re pushing air with fans around a room or house. The temperature is controlled centrally and independent controls are also mounted on each panel, meaning that you can adjust temperatures in different rooms depending on preferences.
Efficiency- water from the boiler (the source) stays very hot on its journey around the house because it's a better conductor than air. Air in a ducted system cools quickly from the unit to the duct. Next, heat from the panel heats slowly, but it heats evenly and does not tend to gather unevenly near the roof or in corners. Lastly, hydronic heaters use a gas boiler. Gas is typically much cheaper than electricity and has been shown to cost 50% to 60% less than it’s electrical counterpart.
Health- hydronic heat is hygienic and gentle. There’s no draughts and no ducted system the air has passed through. Hydronic heating has major benefits for those with allergies or weakened immune systems. If you suffer from allergies and are prone to eye, nose, throat or skin allergies then hydronic heating has big advantages and should be given careful consideration.
