Hydronic Heating & Cooling

The word ‘hydronic’ means a cooling or heating system that transfers heat by circulating water through a closed system of pipes. The water can be heated or cooled to provide a home heating or cooling system. Find out more about the benefits of using hydronics to heat or cool your home and how Australian Hydronic Heating and Cooling can help you find the best solution.

While hydronic systems are usually associated with heating your home, they are also efficient at providing cooling for your home. Just as hydronic systems increase the water temperature to provide heating, a small decrease in the water temperature can provide cooling to your home in the summer months. 

Hydronic heating and cooling systems are also considered healthier than air conditioning systems as they don’t blow allergens and contaminants around your home, or create drafts. While the upfront costs are often higher, the long term financial and health benefits are worth the initial investment. These systems can be installed when renovating or in new builds. 

What is Hydronic Heating?

Hydronic heating heats water within a boiler, usually via gas, heat pumps, solar or wood or pellet burners. Once used the water is returned to the boiler to be reheated, as demonstrated in the diagram to the right. This ‘heating’ system is separate to the homes domestic hot water supply.

Panel radiators or pipes installed underfloor operate as heat emitters, pushing out natural radiant heat which spreads evenly. The radiators or underfloor heating in each room can be individually adjusted via thermostats to provide different temperatures in different areas of the house

Hydronic heating is popular all over the world, and is becoming increasingly popular in Sydney and across Australia.

Benefits of Hydronic Heating

One of the most popular forms of hydronic heating is to use radiators, usually attached to a wall and placed within individual rooms to allow for heating rooms as and when needed. Read more

The other popular heating method for hydronic systems is underfloor heating, where pipes are installed under the floor providing an even radiant heat throughout the room. The pipes can be placed below any floor surface (tiles, wood, carpet, concrete, marble, etc.) and are installed either within a concrete slab, within screed above the slab, or directly below the floor covering.

Often installing underfloor heating or radiators is not an option for many homes, but there are hydronic alternatives. Plinth Heaters offer a great alternative if you want to heat your kitchen or laundry but don’t want to take up valuable room with radiators or wall mounted air conditioners. A similar space saving alternative is ThermaSkirt, which replaces your skirting board with a hydronic heating system that heats your home. Trench heaters or Fan Convectors use your hydronic system to pump heated air into your room through trench heaters in your floor or fan convectors on your walls.

While gas, heat pumps and solar are the most popular methods of energy for heating the water used in hydronic heating, wood or pellet burners offer a viable alternative, either as large boilers located in a garage or shed, or as a feature stove in a living room. Read more

Once your hydronic heating system is installed it is important to have it cleaned and flushed regularly. Australian Hydronic Heating and Cooling use top of the range technology to flush the radiators and pipes to ensure the most efficient operation of your heating system. Read more

Hydronic Cooling

Just as hydronic systems can be used to heat water and your home, they can also be used to cool water and therefore cool your home in summer. Similar to the heating system, cold water is passed through pipes which can be installed in ceilings, floors or walls. The water temperature only needs to be a few degrees below the desired indoor room temperature. This means it is very efficient to run and provides an even distribution of temperature compared to an air conditioning system.

Combining a hydronic heating and cooling system can provide you with year round temperature control for your Sydney home – a very efficient and cost effective solution. Find out more about our hydronic cooling solutions. Read more
