Installing the right hot water system starts with choosing a unit that suits your property, household size and water usage. We install gas, electric, continuous flow, solar and heat pump hot water systems across Perth, including new installations and upgrades to existing systems.

Hot Water Replacement
If your hot water system is old, inefficient, frequently breaking down or no longer economical to repair, replacement may be the better option. We can assess your existing system and help you choose a suitable replacement based on your hot water needs, available space and budget.

Choosing between gas, electric, continuous flow, solar and heat pump systems can depend on your household size, hot water usage, available space and budget. Marchant Plumbing and Gas can assess your needs and help you choose a suitable option for your property.
Hot Water System Types
Choosing the right hot water system depends on your household size, water usage, available space, energy source and budget. Marchant Plumbing and Gas works with a range of hot water systems across Perth and can help you compare the options before installing or replacing a system.
Gas Hot Water Systems
Gas hot water systems provide reliable heating and can be a practical choice for properties with an existing gas connection. Our gas plumbers in Perth can assist with gas hot water installations, connections and related gas plumbing requirements. Options include storage and continuous flow systems, with different capacities available to suit household and commercial requirements.
Electric Hot Water Systems
Electric hot water systems are widely used and can provide a straightforward option where gas is unavailable or unsuitable. Systems are available in different sizes, allowing the unit to be matched to your property’s hot water demand.
Instant Hot Water Systems
Instant, or continuous flow, hot water systems heat water as it is required rather than storing heated water in a tank. They can save space and provide a continuous supply of hot water when the system is correctly sized for the property.
Solar Hot Water Systems
Solar hot water systems use energy from the sun to heat water, with a booster available when additional heating is required. They can reduce reliance on conventional energy sources but require suitable roof space, positioning and installation conditions.
Heat Pump Hot Water Systems
Heat pump systems use heat from the surrounding air to heat water and can provide an energy-efficient alternative to traditional electric storage systems. They are increasingly popular for Perth homes looking to reduce hot water energy consumption and long-term running costs.
Best Hot Water System for Perth Homes
Choosing the right hot water system for Perth’s climate means balancing efficiency, household needs, and your home’s layout. With plenty of sun year-round, a solar plus heat pump combo is ideal for long-term energy savings and a reduced carbon footprint. Gas instantaneous systems, on the other hand, are perfect for homes with high hot water demand, offering fast, reliable supply. If you already have solar PV panels, a heat pump system will reduce energy draw even further. But what’s the best system if your home has space or installation limitations? The answer depends on factors like roof space for solar or ventilation for gas. At Marchant Plumbing and Gas, we take all of this into account. We assess your property, usage, and preferences to recommend the most efficient, cost-effective solution tailored specifically to your lifestyle and Perth’s unique conditions. Trust our local expertise to get your hot water system right the first time.
Heat Pump vs Gas Hot Water Systems
Deciding between a heat pump and a gas system starts with understanding how each performs in Perth homes. Heat pumps have a higher upfront cost but offer significantly lower running costs, especially when combined with solar. They’re also quieter and environmentally friendlier. Gas systems are cheaper to install, reliable in all weather, and provide instant hot water, though they can lead to higher long-term gas bills. Do heat pumps work well during Perth’s colder mornings? Yes, they may slow down slightly but still perform efficiently overall. Consider your household size, available rebates, and energy compatibility when choosing. If you’re still weighing your options, our in-depth guide on heat pump vs gas hot water in Perthbreaks down everything you need to make the right decision. If you want simplicity and immediacy, gas may suit you. If long-term savings and sustainability matter more, heat pumps are the smarter pick.
What Size Hot Water System Do I Need?
Sizing your hot water system correctly ensures comfort and efficiency. As a rule, 30–50 liters per person per day is standard for storage systems. Small homes (1–2 people) typically need 90–130L storage or 16L/min instant systems. Medium-sized homes (3–4 people) should consider 160–250L or 20–24L/min options. Larger households (5 or more) need 300L+ storage or 26L/min instant flow systems. What if you have high appliance usage? Always account for dishwashers, laundry, and baths in your estimate. Choosing the wrong size can lead to either cold showers or higher bills. We assess your home’s layout and usage to recommend the perfect fit.
Hot Water System Installation Cost in WA
Understanding installation costs helps you plan smarter. In Perth, gas instantaneous systems cost approximately $1,800–$2,500 fully installed. Heat pumps range from $2,500–$3,500, especially after applying eligible rebates. Solar systems cost the most, from $3,500–$5,000+, depending on your roof size and tank needs. What extra costs should you expect? These might include switchboard upgrades, valve replacements, or old unit disposal. The good news is, WA government rebates and Small-scale Technology Certificates (STCs) can shave hundreds off your upfront costs. To make sure you claim everything you’re eligible for, read our guide on how to claim government hot water rebates in WA.

We’ll provide a transparent quote and help you apply for every available incentive.
Repair vs Replacement: What’s Better?
Choosing between repair or replacement depends on your system’s condition. If your unit is less than 8 years old, with no rust or major leaks, a repair is often the smarter move. However, if the tank is leaking, the heating element fails repeatedly, or parts are no longer available, replacement is the better option. If you’re unsure which direction to take, read our guide on signs your hot water system needs replacement or just a repair for more clarity. Wondering if it’s worth upgrading to a newer model? More efficient systems, like heat pumps, often lead to long-term savings. Some come with 5–10 year warranties, adding peace of mind. Before making a decision, always have a licensed plumber assess if a simple part replacement like an anode rod or valve could extend your system’s life.

Frequently Asked Questions
Why are hot water system quotes so different between companies?
Hot water system quotes can vary depending on the type and size of the unit, installation requirements, plumbing or electrical changes and what is included in the quoted price. We provide clear quotes so you understand the system, installation and associated work before proceeding.
Are heat pump hot water systems really worth it in Perth’s climate?
Heat pump systems can be a good option for Perth homes because they use heat from the surrounding air to heat water and can use less electricity than traditional electric storage systems. Whether a heat pump is right for your property will depend on your household size, hot water usage, installation location and budget.
What size hot water system do I need?
The right size depends on your household size, daily hot water usage, number of bathrooms and the type of system you choose. A correctly sized system should provide enough hot water for your household without paying for unnecessary capacity or regularly running out of hot water.
Can I repair my hot water system instead of replacing it?
In many cases, yes. Whether repair or replacement makes more sense depends on the age of the system, the fault, availability of replacement parts and the cost of the repair. We can assess the system and recommend repair where practical rather than replacing a unit unnecessarily.
How long does hot water system installation take?
Many straightforward hot water system replacements can be completed within the same day. Installation time can vary if the new system requires changes to existing plumbing, gas or electrical connections, relocation of the unit or other installation work.
