Replace your old electric or gas hot water system with a high-efficiency heat pump. Victorian Energy Upgrades rebates reduce upfront cost. Serving Frankston to Portsea.
If your home still runs an old electric storage hot water system, you're likely spending $600–$1,200 a year just to heat water — and a large portion of that is waste from an inefficient heating element. Heat pump hot water systems are now the smarter choice: they use 65–75% less electricity, qualify for Victorian government rebates, and integrate perfectly with solar panels. Impulse Electrical installs heat pump systems across the Mornington Peninsula and handles all the electrical work — from disconnecting the old system to commissioning the new one.
Prices are indicative after VEU rebate. Exact rebate depends on your current system and household size. We confirm exact rebate at time of booking.

Victorian households can access Victorian Energy Upgrades (VEU) program rebates, which typically reduce the upfront cost by $500–$1,000+ depending on your current system and household size. Replacing gas hot water attracts higher rebates than replacing electric. The rebate is applied as a point-of-sale discount — you don't need to apply separately. Some products also qualify for federal Small-scale Technology Certificates (STCs). Amounts change periodically — call us and we'll confirm current values for your situation.
A heat pump hot water system works like a reverse air conditioner — it extracts heat from the surrounding air and uses it to heat water stored in a tank. This is 3–4× more efficient than a traditional resistive electric system (which uses an element like a kettle). Instead of consuming 1kWh of electricity to produce 1kWh of heat, a heat pump produces 3–4kWh of heat for every 1kWh of electricity used. Most households switch from a resistive electric system and see their hot water bill drop by 65–75%.
After VEU rebates, a heat pump hot water system installed typically costs $1,800–$3,500 depending on brand, tank size, and whether any electrical work is needed. Without rebates, units cost $2,500–$5,000+ installed. At $400–$900/year in energy savings, most systems pay for themselves in 3–6 years. We'll provide a full quote including any electrical scope and confirm applicable rebates.
Yes. Modern heat pump systems operate efficiently down to -10°C. Peninsula winters rarely get below 3–5°C overnight, so cold-weather performance is not a concern. Premium brands like Sanden and Reclaim use CO₂ refrigerant, which is particularly efficient at low ambient temperatures. Most systems also have a backup resistive element for extreme conditions, though this rarely activates in Victoria.
Sanden and Reclaim Energy use CO₂ (R744) refrigerant — more environmentally friendly, very efficient in cold conditions, and particularly good for coastal Peninsula properties as the refrigerant circuit is more corrosion-resistant. Both have 15-year tank warranties. Rheem Ambiheat and Dux use conventional refrigerants, are well-priced, widely available, and have a strong service network. Stiebel Eltron is German-engineered with excellent cold-weather performance. We stock and install all major brands and can recommend the right one for your property.
Yes — and this is one of the best combinations available. If you have solar panels, you can program your heat pump to run during the middle of the day (peak solar generation) on a time-of-use tariff or via a solar diverter. The result: you're using free solar energy to heat water. Many Peninsula households with solar run their heat pump almost entirely on solar, with their hot water cost approaching zero. We can set up the timer or solar diverter connection as part of the installation.
We handle the electrical side — disconnecting the old system, connecting the new heat pump to power, installing or verifying safety switches, setting up off-peak tariff wiring or solar diverter connections, and issuing a Certificate of Electrical Safety. The water plumbing connections (pipes, tempering valve, etc.) are done by a licensed plumber. We work with several Peninsula plumbers and can coordinate the full installation — most jobs are done in a single day.
Yes, and the VEU rebate for switching from gas to heat pump electric is typically higher than switching electric-to-electric, reflecting the additional emissions benefit. You'll also save your daily gas supply charge if hot water is the only thing keeping you on gas. There is additional plumbing work involved (capping the gas supply, re-routing water connections), but it's very commonly done on the Peninsula as gas appliances come to end of life.
