Gas Hot Water System Installation Costs
- Storage Gas Systems: $1,500 – $3,200
- Continuous Flow Gas Systems: $1,700 – $4,000
Gas systems tend to have lower running costs but require access to natural gas or LPG. If gas plumbing needs to be installed, this adds to the cost.
Electric Hot Water System Installation Costs
- Storage Electric Systems: $1,000 – $3,200
- Instantaneous Electric Systems: $1,700 – $4,000
Electric systems have lower upfront costs but can be expensive to run, especially if not connected to off-peak electricity tariffs.
Solar Hot Water System Installation Costs
- With Gas or Electric Booster: $5,000 – $11,000
Solar systems have the highest upfront cost but offer long-term energy savings. Government rebates may reduce the initial cost.
Heat Pump Hot Water System Installation Costs
- Estimated Cost: $3,500 – $7,500
Heat pump systems use ambient air to heat water, making them highly energy-efficient. They qualify for rebates but have higher installation costs.
Additional Costs to Consider
✔ Removal of old system – Typically $100 – $300, depending on the type of system being replaced.
✔ New plumbing or gas connections – If modifications are needed, additional costs range from $500 – $2,000.
✔ Upgrading electrical supply – For electric systems, additional wiring or circuit upgrades can cost $300 – $1,500.
✔ Government rebates – Rebates for solar and heat pump systems can reduce costs by up to $1,000 or more.
