About hot water in Cooroy
Cooroy has older timber homes in town and acreage on the surrounding hills.
In older timber homes, the hot water system is often under the house or on a back verandah, sometimes beside older copper or galvanised pipework. When we replace a system in a home like this, we check the connections and valves around it as well as the heater itself.

As a rough guide, a family of three or four usually needs about a 250 litre electric or heat pump tank, or a continuous flow unit of around 20 to 26 litres a minute.

Where there's no mains gas, gas systems run on LPG cylinders, so electric tanks and heat pumps are the most common choices. Eligible heat pump and solar models also attract STC incentives that reduce the upfront price.
How can I make hot water safer and easier to use in a Cooroy home?
The median age in Cooroy was 50 at the 2021 Census, so scald safety and simple controls matter in many homes. A correctly set tempering valve keeps bathroom water at no more than 50°C, which is required in Queensland on new and replacement systems. We can also position a new system so valves are easy to reach, and explain the controls before we leave.
How much does a new hot water system cost in Cooroy?
New hot water systems in Cooroy start from $1,700 supply and install. The price depends mainly on the system you choose. For Cooroy homes we also allow for whether it's a like-for-like swap or a change of system type. You get a fixed price before any work starts, with no call-out fee and no travel surcharge, and every install has our lifetime workmanship warranty. With Cooroy households averaging 2.4 people (2021 Census), the size you need is the biggest factor in the price.
