Hot Water Systems done properly
Hot water always seems to fail on the coldest morning. MLC repairs, replaces and installs hot water systems right across South-East Perth — gas, electric, solar and heat pump — and we’ll give you straight advice on whether a repair makes sense or whether you’ll save money replacing an ageing unit. We carry common parts and stock major brands, so many jobs are sorted on the first visit.
Repair or replace? We’ll tell you straight
A system under about 8–10 years old is often worth repairing; much older than that and you’re usually better off replacing it before it fails completely. We’ll assess yours, explain the realistic options and their trade-offs, and let you decide — no pressure to buy a new unit you don’t need.
Sizing a new system for your home
Choosing the right size and type matters for both comfort and running costs. We’ll match the system to your household size, energy setup (gas vs electric vs solar) and budget, and handle the full installation and old-unit removal.

- Supply and installation of new hot water units
- All major brands — Rheem, Dux, Rinnai, Bosch, Vulcan and more

Hot water systems we work on
Gas storage systems
A gas-fired burner heats a tank of water ready for use, giving you fast recovery and lower running costs than electric. We repair and replace gas storage units of every size and handle the gas fitting safely as a licensed gas fitter.
Electric storage systems
The most common system in many local homes — simple, reliable and easy to service. We replace failed elements and thermostats, swap corroded tanks, and can move you onto a more efficient off-peak setup where it makes sense.
Continuous flow systems
Also called instantaneous or tankless, these heat water on demand so you never run out — ideal for busy households and smaller spaces. We size them to your hot water demand and install or repair gas and electric models.
Solar hot water systems
Roof-mounted or split-system solar can dramatically cut your energy bills using free heat from the sun, with gas or electric boosting for cloudy days. We service the panels, tanks, pumps and boosters and replace ageing components.
Heat pump systems
Heat pumps pull warmth from the surrounding air to heat your water for a fraction of the energy of a standard electric system. We advise on whether one suits your home, then handle supply, installation and ongoing repairs.

When to call us
No hot water at all
A dead system can be a pilot light, element or thermostat — often a straightforward repair.
Water runs out quickly
Short bursts of hot water usually point to a failing element or a tank near end of life.
Rusty or discoloured water
Brown hot water often means the tank is corroding internally and may need replacing.
Leaks or pooling water
Water around the base of the tank is a sign the cylinder is failing — don’t leave it.
