Gas hot water system replacement

A Haier heat pump replacing a gas system is from $3,080 inc GST for the 250L and from $3,355 for the 330L, installed, with the rebates already taken off. Gas systems earn a smaller NSW rebate than electric tanks, so the price is higher than our electric swap, but you also stop paying a gas supply charge every quarter. We cap the gas at the hot water system, run the heat pump on your existing power, and quote from photos of the current unit.

How Much Will You Save?

Hot water heating typically accounts for 20 to 25% of a household electricity bill. Switching from a standard electric storage system to a heat pump cuts that cost by up to 70%.

At $450 to $650 per year in savings, most NSW households recover the cost of a Haier or Rinnai heat pump within 3 to 5 years.

Heat Pumps and Solar Panels: Better Together

Feed-in tariff rates in NSW have dropped to 5 to 8c/kWh, meaning you earn very little by exporting excess solar to the grid. A heat pump draws around 1kW to operate, meaning even a modest 3kW solar system can power your hot water heating during peak generation hours at effectively zero cost. We programme your heat pump timer to run during solar generation hours, typically 9am to 3pm, at no extra charge. NSW households with solar who add a heat pump typically see hot water running costs drop from $700 to $1,000 per year to under $100 per year.

How Does a Heat Pump Hot Water System Work?

A heat pump doesn’t generate heat. It moves heat from the surrounding air into the water tank using a refrigeration cycle. The electricity only powers the fan and compressor: the actual water heating is done by ambient air temperature. For every 1kW of electricity used, a heat pump delivers 3 to 5kW of heating energy. Here’s the process step by step:

• Step 1: A fan draws warm air across an evaporator coil containing liquid refrigerant
• Step 2: The refrigerant absorbs warmth from the air and evaporates into a gas
• Step 3: A compressor pressurises the gas, raising its temperature significantly
• Step 4: The hot gas passes through a heat exchanger in the water tank, transferring heat to the stored water
• Step 5: The refrigerant cools back to liquid and the cycle begins again

Heat pumps work effectively in temperatures as low as -10°C, reliable year-round across all of NSW including alpine areas.

Frequently Asked Questions: NSW Heat Pump Hot Water 2026

Is the NSW heat pump hot water rebate still available in 2026?

Yes, NSW Energy Savings Scheme discounts for household hot water upgrades continue in 2026. The rebate is applied as an upfront discount at installation: you don’t lodge a claim or wait for a refund. Efficient Energy Group handles all ESS and STC paperwork as your accredited provider.

How much is the rebate worth in 2026?

As at October 2026 a Haier 250L replacing an electric tank creates 28 NSW Energy Savings Certificates and 16 federal STCs, worth about $1,420 together at current certificate prices; the 330L creates 26 and 15, about $1,320. Certificate prices change daily, so treat these as a guide. Both are already taken off the installed prices on this page.

How much does a heat pump cost in NSW after rebates?

After all government rebates: Haier $2,310 inc GST, Rinnai $2,999 inc GST installed, Rheem from $2,999, and Reclaim Energy CO2 from $4,400. All prices include supply, installation by a licensed plumber, and removal of your old system.

What size heat pump do I need?

As a general guide: 200 to 250L suits 1 to 3 people, 270 to 280L suits 3 to 4 people, and 300 to 315L suits 4 to 6 people. We confirm the right size for your household as part of your assessment.

Can a heat pump be installed indoors?

Heat pumps need access to ambient air and are generally installed outdoors or in a large well-ventilated space such as a garage. We confirm the best location during your site assessment.

How long does installation take?

Most installations are completed in a single day. Our licensed plumbers and electricians handle everything: removal of your old system, installation, electrical work, timer programming for solar integration, and compliance certification.

Will a heat pump work through winter in NSW?

Yes, all systems we install operate down to -10°C. NSW winters don’t get cold enough to impact performance significantly. All systems also include a backup electric heating element that activates automatically if needed.

Can I get a heat pump as a renter?

Yes, renters can access the NSW rebate with landlord consent. The upgrade doesn’t structurally alter the property and most leases permit energy efficiency upgrades.

What happens to my solar feed-in tariff?

Adding a heat pump improves your solar economics. Instead of exporting excess solar at 5 to 8c/kWh, you use it to heat water, saving the 30 to 40c/kWh cost of grid electricity for hot water. We programme your timer to run during solar hours automatically.

How the Two NSW Rebates Work Together

NSW is one of the few states where two incentives stack on a heat pump. The federal Small-scale Renewable Energy Scheme awards STCs based on the energy the unit displaces over its rated lifetime: 16 for a Haier 250L in Sydney. The NSW Energy Savings Scheme awards Energy Savings Certificates for the electricity saved: 28 for the same unit replacing an electric tank. Together they are worth about $1,420 at current certificate prices, and we take that value off your installed price rather than you claiming it. Efficient Energy Group is accredited under both schemes and creates the certificates on install day.
