Hot Water System Installation

Tell us what you need
Send your address, the model or size you are looking at, and photos of your current hot water system and where it sits.
We check and quote
We check if a licensed installer can do the job in your area and send you a quote before anything is booked.
Licensed work only
Hot water systems must be installed by a licensed plumber, with an electrician for the power. Keep the compliance paperwork for your warranty.

What affects the installation price
- A like-for-like replacement in the same spot costs the least.
- Moving the system to a new location adds pipe and electrical work.
- Changing from low pressure to mains pressure usually needs extra valves and pipework.
- A hot water heat pump needs a level base outside for the unit and enough space around it for air flow.
- Taking away the old cylinder is quoted separately.
What size do you need?
Hot water use depends on showers, baths and appliances. These are common starting points for a household:
| Household | Typical tank size |
|---|---|
| 1 to 2 people | 150 to 180 litres |
| 3 to 4 people | 250 to 300 litres |
| 5 or more people | 300 litres and up |
Long showers, a spa bath or more bathrooms push the size up. Send us your household size and we will suggest suitable models.
