About hot water in Caloundra West
Caloundra West includes a large part of the Aura community, so many homes here are recent builds.
Builder-installed heat pumps and solar
Many homes in the Aura community are recent builds, and some came with a heat pump or solar system chosen by the builder. If yours is past its warranty and playing up, common faults like fans, sensors and condensate drains are often repairable.
Tight side paths
Estate blocks often leave a narrow side path for the hot water system. A heat pump needs clear airflow and shouldn't sit under a neighbour's bedroom window, so placement matters as much as the model.
Rentals need fast swaps
If you own a rental in Caloundra West, tenants without hot water need a fast fix. Like-for-like replacements reuse the existing connections, which keeps the job to a few hours.

Electric hot water replacement in Caloundra West
The existing hot water system at this Caloundra West home had failed, and it was more than 10 years old. With a tank that old, another repair would probably only have bought a short extension, so replacing it was the better-value option.
The new electric storage system went onto a fresh concrete base beside the brick wall, with new valves, a tempering valve and fully insulated hot and cold lines.
Once the new system was running, we tested it at the taps, removed the old unit and lodged the compliance with the QBCC. The homeowner is covered by our lifetime workmanship warranty.

What size hot water system does a typical Caloundra West home need?
It depends mostly on how many people live in the home and how many bathrooms run at once. 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. Smaller households of one or two people usually do well with a 125 to 160 litre electric tank, a compact heat pump, or a continuous flow unit of around 16 to 20 litres a minute. Off-peak electric tanks need to be bigger, because they heat only once or twice a day. We confirm the right size when we quote.
