Sources: Wikipedia, GDP suburb profile (ABS data). Population figures are from the 2021 Census. The hot water advice on this page is general and applies differently to every property.
On acreage, it's common to have tank or bore water, LPG, and a long pipe run between the hot water system and the house. A long run means a longer wait at the tap, so placement is worth thinking about when a system is replaced, and sheds or granny flats sometimes need their own small system.

Common hot water problems and what they mean
Every property is different, but these faults are common in acreage properties, depending on the system's age, where it's installed and the water supply.
- Long wait for hot water at the tapThe system is far from the bathroom. Relocating it or adding a second unit fixes it.
- LPG running out or pilot going outCommon on rural gas systems. Many owners switch to a heat pump instead.
- Discoloured hot water on tank or bore supplyUsually a worn anode or sediment build-up.

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. 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.
Which type of hot water system works best in Diddillibah?
If your property in Diddillibah runs on tank water, have the anode checked more often, and where there's no mains gas, gas systems run on LPG. About 91% of Diddillibah dwellings are separate houses (Census Atlas, ABS data), so most homes have outdoor space for a heat pump or a roof suited to solar. Rural roofs and yards suit solar and heat pumps well, and listed models attract STC incentives. LPG continuous flow is a good option where the house already has gas.
Why does our hot water run out so quickly in Diddillibah?
At the 2021 Census, households in Diddillibah averaged 2.6 people, so running out of hot water is a common complaint. Usually the tank is too small for the household, the element or thermostat has failed so only part of the tank heats, or a continuous flow unit is too small for two showers at once. We test which it is before recommending a fix or a bigger system.
How much does a new hot water system cost in Diddillibah?
