About hot water in Cotton Tree
Cotton Tree sits at the mouth of the Maroochy River, with holiday units and older beach homes.
If your home is close to the beach, salt air is usually the biggest factor in how long outdoor hot water parts last. Casings, relief valves, brass fittings and heat pump coils can corrode faster than they would inland, so they're worth checking more often, and the position of a replacement system matters.

Common hot water problems and what they mean
Every property is different, but these faults are common in beachside homes, depending on the system's age, where it's installed and the water supply.
- Relief valve dripping from the overflowSalt air wears relief valves faster, and a constant drip usually means the valve needs replacing.
- Rust at the base of an outdoor tankCorrosion on the outer casing often shows the tank is near the end of its life.
- Heat pump losing performanceSalt build-up on the coil and fins reduces efficiency, and can cause error codes.

What size hot water system does a typical Cotton Tree 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.
Which type of hot water system works best in Cotton Tree?
Near the coast, salt air is the main thing that shortens the life of outdoor hot water parts in Cotton Tree, so stainless or well-protected models last longer close to the beach. Units and apartments often suit a compact electric tank or a gas continuous flow unit. Houses near the beach usually do best with a heat pump in a sheltered spot, particularly if the roof has solar panels. Eligible heat pump and solar models also attract STC incentives that reduce the upfront price.
