Heat pump hot water

Heat pump hot water for Perth homes

A heat pump moves heat from the air into a storage tank. We check household size, installation space, existing services and rooftop solar before specifying the unit and current STC discount.

Based in Hamilton Hill, serving Fremantle and Perth metro

Use less electricity to heat water

A heat pump moves heat from the surrounding air into a storage tank instead of creating all its heat with an electric element. It can use less electricity than a conventional resistance water heater, but tank size, climate, run times and hot water demand all affect the result.

Unisol supplies and installs heat pump hot water systems for homes around Hamilton Hill, Fremantle and the wider Perth metro. iStore is one of the brands we commonly work with, while the final recommendation depends on household size, installation space, the existing system and product availability.

A natural partner for rooftop solar

A heat pump can be scheduled to heat water during daylight hours, when rooftop solar is producing. The best run window still needs to leave enough hot water for the household and allow the unit time to recover.

STCs and the price on your quote

Eligible heat pump water heaters can create federal Small-scale Technology Certificates. These are commonly assigned as an upfront discount, with the value depending on the approved model, location and certificate market. Your quote will show the current net price rather than relying on an old headline rebate figure.

FAQ

Heat pump questions

What is a heat pump hot water system?

A heat pump uses electricity to move heat from the surrounding air into the water tank. It can use much less electricity than a conventional electric resistance water heater, although results depend on the household, system size, location and operating settings.

Can a heat pump work with rooftop solar?

Yes. Scheduling a heat pump to run during solar-producing hours can help a home use more of its own solar. We consider your household hot water needs, available space and existing electrical setup when recommending a system.

Are heat pump hot water rebates available in WA?

Eligible heat pump water heaters may receive federal Small-scale Technology Certificates, which are commonly applied as an upfront discount. Eligibility and certificate values can change, so the current amount should be confirmed on your quote.

Which heat pump brands do you install?

iStore is one of the heat pump brands Unisol commonly works with. Product recommendations can change as models, availability and the needs of each property change.
