About hot water in Mountain Creek
Mountain Creek is an established family suburb between Mooloolaba and Buderim.
If your home still has an older electric storage tank in the laundry, under the house or outside, and it's 10 to 15 years old, a leak from the base or a relief valve that won't stop running usually means it's due for replacement. Many tanks of this age run on an off-peak tariff, which a like-for-like replacement can keep.
A recent hot water job in Mountain Creek

Dux continuous flow gas hot water replacement in Mountain Creek
This Mountain Creek home runs its hot water on LPG, and the existing gas unit was due for replacement.
We installed a new Dux Endurance gas continuous flow unit on the outside wall and replaced the gas supply with all-new, upsized copper gas lines from the LPG cylinders to the heater. Upsizing the line makes sure the unit gets enough gas to deliver its full flow rate, so the hot water stays steady even with more than one tap running.
Everything was tested and commissioned before we left, the gas work was certified and the compliance lodged. Like every install we do, it's covered by our lifetime workmanship warranty.

What size hot water system does a typical Mountain Creek home need?
Mountain Creek has a lot of larger homes: about 55% have four or more bedrooms (2021 Census). Households average 2.8 people. As a rough guide, a busy household in a four or five bedroom home usually needs a 315 litre or larger electric or heat pump tank, or a gas continuous flow unit of around 26 litres a minute or more if two showers run at once. 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 Mountain Creek?
For the larger homes common in Mountain Creek, a big heat pump or a high-flow gas continuous flow unit keeps up with several bathrooms. About 52% of Mountain Creek households have three or more people (2021 Census), so recovery time matters: a system that reheats quickly avoids cold showers at busy times. A like-for-like electric tank is the quickest and lowest-cost swap. If you have solar panels or want lower running costs, it's worth comparing a heat pump at the same time. Eligible heat pump and solar models also attract STC incentives that reduce the upfront price.
