What’s involved in a gas hot water system installation
Installing a new gas hot water system is more complicated than swapping one unit for another.
Getting the size, type and setup right from the start means less hassle, whether that’s running out of hot water halfway through the week or paying more for hot water you’ll never use.
From our experience installing gas hot water systems, here’s what we take care of:
- Understanding your household’s hot water demand.
- Recommending a storage tank or continuous flow (instant) system to suit your property.
- Selecting the right tank size or flow rate.
- Confirming your gas supply type, whether that’s mains natural gas or bottled LPG.
- Safely removing and disposing of the old hot water system. Positioning the new unit to meet Australian Standards and local requirements.
- Connecting gas supply, water supply and drainage.
- Fitting a compliant flue where the unit requires one.
- Fitting tempering valves and pressure and temperature relief valves for safety and compliance.
- Testing and commissioning the new system before we leave, including a full gas leak check.
As licensed gas fitters, we handle the gas connection ourselves, so you usually don’t need to bring in another trade to finish the job.

What are people saying about us
Do You Need Your Hot Water System Repaired?
Frequently Asked Questions
How do I know what size gas hot water system I need?
Sizing depends on your household size, number of bathrooms and how you use hot water. Storage tanks generally range from around 130L for a small household up to 170L or more for larger families, while continuous flow systems are sized around your peak simultaneous demand rather than a set volume. We’ll assess your household during your quote and recommend a size that won’t leave you running cold.
Storage tank or continuous flow, which is better for my home?
A storage tank heats and stores a set volume of water ready to use, which usually costs less upfront but limits hot water to what’s in the tank. A continuous flow (instant) system heats water on demand, so you get an unlimited supply, and gas continuous flow units are generally more compact and efficient than their electric equivalents. Which one suits you best depends on your household size, hot water usage, and budget, and we’re happy to talk through the trade-offs before you decide.
How long does a gas hot water system installation take?
A straightforward like-for-like replacement can usually be completed within a few hours in a single visit. Installations that involve relocating the unit, connecting a new gas line or fitting a flue for an indoor unit may take longer. We’ll give you a clear timeframe as part of your quote.
Can you remove and dispose of my old hot water system?
Yes, removing and safely disposing of your old system is included in our installation service, so you don’t need to arrange anything extra.
Do you install a specific brand of gas hot water system?
We install and work with all major brands, including Rheem, Dux, Aquamax, Thermann and Bosch. If you have a preferred brand, we’re happy to install it, and if you’re not sure what suits your home, we can recommend a system based on your household’s needs.
Can you install a gas hot water system if I’m on bottled LPG rather than mains gas?
Yes, we install gas hot water systems for homes on both mains natural gas and bottled LPG. The unit and fittings required differ slightly between the two, so we’ll confirm your gas supply type during your quote to make sure the right system and setup are recommended.
Do you provide gas hot water installations throughout Perth?
Yes, we install gas hot water systems for homes and businesses throughout the Perth metropolitan area.
