Which hot water system is right for you?

There are four types. Each one suits a different kind of house.

  • Electric storage

    The lowest price to buy and fit. Running it costs more, unless it runs on off-peak power or your own solar panels.

  • Gas

    A burner heats the water, either in a tank or as it passes through a continuous-flow unit. Because of the venting, it's nearly always fitted outside.

  • Heat pump

    Draws warmth out of the air and puts it into a tank of water. Dearer up front, and it uses far less power than a plain electric tank.

  • Solar

    Panels on the roof heat the water, and a booster tops it up on cloudy days. It needs a roof that gets plenty of sun.

Four things usually decide it: how many people live in the house, what the old system runs on, whether your roof gets good sun or already has solar panels on it, and how much you want to spend now compared with what you'll pay on each power or gas bill after.

If the old system has just died and it did the job well, the same type in the same spot is normally the simplest and cheapest swap. Changing to a different type costs more on the day, so it's easier to weigh up before the old one fails.

What we do with hot water systems

Replacing a hot water system

We ask what you have now, how many people use it and whether it's been giving you trouble, then give you the choices: usually the same type again, or a change if it would suit your house better.

Every new or replacement system in Queensland needs a temperature control device, usually a tempering valve, that limits how hot the water gets at your taps, so that goes in as part of the job. We check every joint for leaks and make sure it's heating before we go.

When you ring, we'll tell you when we can do the swap.

Hot water repairs

A lot of hot water faults come down to one part: a relief valve that won't stop dripping, a worn-out element or thermostat, a gas unit that won't light, or a solar pump that has stopped. These can often be fixed for a lot less than a new system.

A tank that has rusted through and is leaking can't be repaired. A new system is the only fix.

Hot water servicing

It depends on the type of system, but we recommend a check every year and a service about every 3 years, which helps it last longer and run more efficiently. The service picks up the small things before they leave you without hot water: the relief and tempering valves, the fittings for leaks and rust, and whether it still heats as it should. On a storage tank we can also check the anode, a metal rod that corrodes first so the tank lasts longer.

Hot water for businesses

We also install and look after hot water in commercial buildings like offices, cafes, shops and medical practices.

Commercial plumbing

No hot water? Check these first

  • Electriclook at your switchboard. If the hot water switch has tripped, turn it back on once. If it trips again, leave it off and ring us.
  • Off-peakthe tank only heats at set times, so after a lot of use it may simply be empty until the next heating period.
  • Gascheck you haven't run out of gas, and whether your other gas appliances still work.
  • Leakingturn off the cold water valve on the pipe going into the tank, then turn off the power or gas to it.

Then ring 0413 291 781 between 7:30am and 4:30pm, Monday to Friday, and tell us what it's doing.

Signs your hot water system needs looking at

Any one of these is worth a call. Some are a small repair if you get them looked at early, and a new system if you leave them.

  • No hot water, or water that swings between hot and cold
  • Water leaking from the tank or the pipes around it
  • Rusty-looking water, or a strange smell from the hot tap
  • Hot water running out sooner than it used to
  • Power or gas bills going up with nothing else changed

How a hot water job works

  1. Tell us what's happening

    Let us know what system you have and what's going on. A few photos can often help us understand the job before we attend.

  2. We work out the best option

    We'll assess whether the system can be repaired or whether replacement makes more sense, then talk you through the suitable options.

  3. Clear pricing and booking

    Once we know what's required, we'll confirm the price and arrange a suitable time to carry out the work.

  4. Install, test and show you how it works

    We complete the repair or installation, test the system properly and show you anything you need to know before we finish up.

What a hot water system costs

The type of system moves the price more than anything else. Electric storage costs the least to buy and fit. Gas sits in the middle. Heat pumps and solar cost the most to put in and the least to run.

After that, the price comes down to:

  • the size of tank, or for a continuous-flow unit, how much hot water it has to deliver at once
  • whether it goes where the old one was, or the pipes, drain or gas line have to be moved
  • for solar, getting panels and sometimes a tank onto the roof, and how steep or high the roof is
  • for gas, the flue and the space the unit must have around it
  • any electrical work, such as a new circuit or a change of tariff, which a licensed electrician does

Rebates. Rebates for heat pump and solar hot water come and go in Queensland.

Comparing quotes. Check each one is for the same size and type of system, whether it's supply and install or supply only, that it includes the tempering valve, and whether taking the old unit away is part of it.

Chris and his apprentice did a great job of installing our new hot water system. They were time efficient, did a clean and tidy job, took away the old tank, and were very happy with the hot water system they installed for us. Highly recommended

  • Our hot water tank burst (21 years old) and needed replaced promptly. Chris did an excellent job with installing the new hot water tank. Communication great from start to finish. Quick turnaround on the quote and installed within a couple of days. Highly recommend. Thanks again Chris.

  • We had the gas for our kitchen moved so that it can use the larger bottles further away we use for the hot water. Job was completed on time and on budget exactly as promised. Work is very neat, no shortcuts, everything is joined at corners with specific corner pieces rather than just bending by hand. Really solid job including the connection to the larger pipe, will be recommending.
