About hot water in Twin Waters
Twin Waters is a lake and canal suburb between the Maroochy River and the beach, with larger homes on the water.
Waterfront homes are often larger, and outdoor units sit in humid, salty air. For homes like these, sizing the system to the number of bathrooms and choosing a sheltered position make the biggest difference to how well a new system performs and how long it lasts.

Common hot water problems and what they mean
Every property is different, but these faults are common in waterfront homes, depending on the system's age, where it's installed and the water supply.
- Running out of hot water on busy morningsLarge homes often outgrow the original system. A bigger tank or continuous flow unit fixes it.
- Continuous flow unit going cold with two showers onThe unit or gas supply is usually too small for the demand.
- Corroded fittings near the waterHumid, salty air off the canals attacks valves and brass fittings.

What size hot water system does a typical Twin Waters home need?
Twin Waters has a lot of larger homes: about 50% have four or more bedrooms (2021 Census). Households average 2.3 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 Twin Waters?
Near the coast, salt air is the main thing that shortens the life of outdoor hot water parts in Twin Waters, so stainless or well-protected models last longer close to the beach. For the larger homes common in Twin Waters, a big heat pump or a high-flow gas continuous flow unit keeps up with several bathrooms. About 57% of Twin Waters households are two people (2021 Census), so a mid-sized tank or a modest continuous flow unit usually covers it. For larger homes, a gas continuous flow unit (sometimes two linked together) or a heat pump of around 300 litres or more are the usual 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 Twin Waters home?
The median age in Twin Waters was 60 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 Twin Waters?
New hot water systems in Twin Waters start from $1,700 supply and install. The price depends mainly on the system you choose. For Twin Waters homes we also allow for the bigger tank or higher-flow unit that larger homes need and salt-resistant fittings and a sheltered position close to the beach. 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 about 50% of Twin Waters homes having four or more bedrooms (2021 Census), many need a larger system, which costs more than a standard 250 litre tank.
