Important Pricing Information

Our listed prices apply to standard, like-for-like replacements of existing hot water systems, assuming the new unit is similar in type and easily accessible.

If your setup requires additional work-such as new pipework or valve upgrades-extra charges may apply. These costs generally range between $85 and $420. Any variations will be clearly explained by our technician before work begins, so you know exactly what to expect.

Please note:
Quoted pricing is based on compliant installations. If your system requires upgrades to meet current plumbing or gas regulations, this may incur additional costs. Again, our team will always discuss these with you upfront.

Specifications

* Sizing assumes AAA or 3 star outlets. For non WELS rated or WELS rated fixtures with higher flow outlets (AA, A, 2 star or 1 star rated), a larger size appliance or additional appliance may be required to deliver adequate performance. This is a guide only, special site and location factors may affect this. Half a shower outlet refers to a guest shower or powder room that is not used all the time. For more information, consult with your hot water specialist.
