Repair or replace?
Not every system needs replacing. Elements, thermostats, pressure relief valves and tempering valves can often be repaired at a fraction of the cost of a new unit. But once a storage cylinder is leaking, replacement is usually the only practical option. We’ll always give you the honest answer on-site, for free.

Hot water questions from Mosman
Clear answers to common hot water questions from Sydney homeowners.
Why is my solar hot water booster running all the time?
The timer or controller may be set incorrectly, a sensor or circulation fault may be preventing solar gain, or household demand may exceed the available solar heat. Continuous boosting defeats much of the systemβs energy-saving benefit.
What size continuous flow hot water system do I need?
Sizing depends on household size, shower flow rates, peak usage, available energy supply and the systemβs recovery rate. A small tank with fast recovery can suit some homes, while larger families or simultaneous showers may need greater storage or continuous-flow capacity.
Why does my gas hot water system keep turning itself off?
Overheating, poor flue performance, blocked filters, unstable gas pressure, failing sensors or restricted water flow can cause shutdowns. The unit should be tested rather than repeatedly reset.
Can I still use my hot water system if it is leaking?
It is safer not to use a heater that is leaking from the tank, electrical area, burner compartment or pipe connections. A small intermittent drip from the relief valve can be normal, but continuous flow or any uncertainty should be checked promptly.
Can I replace a solar hot water system with a heat pump?
Yes. A heat pump avoids roof collectors and can work very well with rooftop solar electricity. Removal of the old collectors, roof penetrations, electrical arrangements and the available ground location must be assessed.
