A building consent is not required to repair or maintain an existing water heater, if it is carried out by an authorised person.
What the law says
Schedule 1 of the Building Act 2004 states the following:
The repair or maintenance of any existing water heater using comparable materials, comparable components, or a comparable assembly.
Guidance on the exemption
This exemption enables an authorised person (refer to the glossary) to repair and maintain water heaters associated with buildings. Any repair work must use comparable materials, comparable components or a comparable assembly.
Examples where this exemption could apply
|Repairing a leaking open-vented water storage heater.|
|Repairing a valve-vented water storage heater.|
|Replacing sacrificial anodes.|
|Repairing valves associated with water heaters (refer to exemption 32 – repair, maintenance, and replacement).|
|Repair or maintaining solar collectors.|
Example where building consent is required
|While repairing his existing (open-vented) storage water heater, the homeowner decides to replace the existing wood burner and wetback system. As replacing the wood burner and wetback is not considered to be repairs or maintenance, the building work requires a building consent.|
