Hydronic heating is an energy efficient system that uses hot water to heat your home. The water is heated by an economical heat source. It is then circulated around the building through radiator panels or underfloor heating pipes. 

If you are investigating the cost of hydronic heating, you should consider that although the system requires a higher initial investment than some other basic forms of heating, the benefits and running cost-savings make it an invaluable addition to your home. We will take you through the different financial considerations and let you know how you can get the most from your investment.

The Lowdown On Costs

The installation cost for hydronic systems vary based on your home. The main concern is how accessible your underfloor or wall cavities are. This will affect how easily your installer can fit the system.

Typically, it is easier to install hydronic heating in a new home as pipes can be laid before concrete is poured or walls plastered. If you are adding the heating system to an existing home, you should consider the costs of accessibility (removing floorboards or parts of the wall) and restoration.


Radiators come in a variety of sizes, designs and materials. At Hunt Heating we offer an extensive range that includes traditional steel designs to our statement designer models. The price of the radiator will depend on what style you seek for you home.

In terms of installation, a standard three-bedroom home costs around $1,200 to $1,500 per radiator if using a standard steel panel. This is inclusive of a standard natural gas boiler cost.

Installing a radiator is more expensive than a few split-systems. However, they are anti-allergic and quietly heat your home rather than expelling loud noise through air vents and have a far greater product lifetime.

Underfloor Heating

In a new home the cost of installation for a traditional in slab method is approximately $70 per square metre, for the more efficient and faster reacting in screed method this is approximately $90 per square metre. If it is an existing home and the circuits are laid on top of the existing concrete slab or sub floor, the cost is around $110 per square metre. These prices exclude the cost of the heat source.

Tips To Get The Most From Your Hydronic Heating

Install A Learning Thermostat

You can help further reduce heating costs by using an energy saving thermostat such as the Nest Learning Thermostat or the Honeywell Wifi 9000.

  • Nest Learning Thermostat
    This device is amazingly intuitive. It monitors your schedule, taking notice of times when you turn the temperature up or down. It then stores this information and creates an automatic schedule for you. This promotes cost savings as it ensures energy is not being wasted.
  • Honeywell Wifi 9000
    You can connect this thermostat to your Wifi and control the heating from anywhere in your home or when you are away or out of the house through the app. It has simple programming that you can use to match your heating to your schedule and an energy saving mode that you can take advantage of.

Upgrade Your Boiler

If you have access to natural gas or LPG, a condensing gas boiler like the Immergas Intec Combi or System boiler, is a great choice for keeping costs down. They are energy efficient, using heat within the expelled gases to reheat the water in the system. Within a couple of seasons the savings could potentially cover the costs of upgrading to an energy efficient boiler.

Insulate Your Home

Heating will only work well in a home if it is not able to escape through unsealed cracks or gaps. The more heat that is able to leak, the higher your energy bill. By insulating your home, you can ensure that you retain the warmth your hydronic system is emitting.
