WA homeowners may be eligible for Small-scale Technology Certificates (STCs) that reduce your upfront cost by hundreds of dollars. We are certified to help you access these rebates — ask us when you call.

Heat Pump Hot Water Systems

Heat pumps extract warmth from surrounding air to heat water, making them one of the most energy-efficient options available — using up to 70% less electricity than a standard electric system.

Units range from $2,500 to $4,000 before installation. Government rebates are available in WA. We’ll help you determine eligibility and factor that into your quote.

Frequently Asked Questions

How much does it cost to install a hot water system in Perth?

Installation costs vary based on system type. Expect $400–$800 for electric systems, and $600–$1,200 for gas or solar systems, depending on the complexity of your setup and existing plumbing.

Which hot water system is most efficient in Perth?

Heat pump systems are the most energy-efficient option for most Perth homes, using up to 70% less electricity than a standard electric system. Solar with a gas booster is a close second and has the lowest annual running costs overall. We can help you weigh up the upfront cost vs long-term savings for your situation.

What kind of hot water system is most common in Perth?

The continuous flow water system is the most common kind of gas water heater in Perth. It’s also referred to as an instantaneous water heater. Because there is no insulation at the point where the gas flame heats the tank, they have very high heat loss.

What size hot water system does a family of four need?

Each person in a household generally uses 50 litres of hot water daily, on average. When it comes to a storage system, it should have 1.5 days’ worth of capacity. In a house with three bedrooms in which four people can comfortably live, a 300-litre tank should be installed. This holds even if a retired couple currently occupies it.

Do you remove the old hot water system?

Yes. We remove and dispose of your old unit as part of every installation. You don’t need to organise anything separately.

How quickly can you install a new hot water system?

In most cases, we can install your new system within 1–2 business days. If you have no hot water and need urgent service, call us directly on 0439 922 548 to discuss availability.

What is the typical lifespan of a 50-litre hot water system?

On average, electric hot water systems last between 10 and 15 years.

What are the main types of hot water systems?

The main kinds of hot water systems that people generally have installed include electric, gas, solar, and heat pump systems. Electric hot water systems heat the water using an element within the storage tank. (The continuous flow or instantaneous hot water system, which only warms the water when you switch on your hot faucets, is another electric choice.) Gas systems are similar to electric, with the difference of gas being used to power the element as opposed to electricity. Solar systems, on the other hand, are growing in demand because it’s considered a ‘green option’; however, the heat pump is the most energy-efficient option on the market.

What’s the difference between instantaneous and storage systems?

Instantaneous systems heat water only when needed, reducing energy waste, while storage systems keep hot water in a tank ready to use. Both come in gas and electric formats.
