Hydronic Heating

Hydronic heating is a simple method of moving heat around using liquids. Water is the most commonly used fluid but steam, oil or propylene glycol are also employed under certain circumstances. Heat or cooling is spread around a property using the process of radiation, from a source such as a radiator or pipework in a trench or under the floor. Hydronic heating differs from forced air heating systems in several respects and is generally regarded as the most comfortable and non-allergenic form of heating available.

With forced air systems, the air inside the space is drawn into a return air duct and passes through a central heat exchanger where it is heated then blown back into the room via vents in the floor or ceiling. During this process, the air becomes drier and dust accumulated in the ductwork can be circulated in the room. Hydronic heating, on the other hand, uses a radiator in each room to act as the heat exchanger and relies on radiation and convection to gently circulate the thermal energy.


Radiators are the most familiar sign of hydronic heating and are available from Automatic Heating in a range of sizes in the Elite range, a contemporary design available in white powder coat finish and the Floreal range, a beautiful replica of the 1920’s cast iron radiators available in a natural “Old Grey” finish.

Valves and Actuators

Thermostatically controlled radiator valves can produce significant improvements in the efficiency of the overall system by limiting the throughput of heated water when a predetermined temperature is achieved which avoids heat spikes and wastage.

Trench Heaters

As the name would suggest, these heaters are recessed into the floor, often where a radiator would be impractical such as in front of windows or doors. The Climateline range that we supply is fully optimised for noise levels, heat output and power consumption.

Hydronic Heating Boilers

With energy costs on a steady rise in Australia, hydronic heating boilers offer a cost effective, healthy and energy efficient heating solution. Automatic Heating provides clients with a complete package of high class products that work in harmony with each other and can be integrated into your already existing system or replace it completely.

Hydronic heating boilers are being implemented for a variety of commercial and industrial applications all over Australia. These systems operate by heating water or other types of fluids to a certain temperature and then circulate those liquids throughout the space via baseboard heaters, radiators, or through the floors.
