Benefits of Moving Your Hot Water Cylinder Outside

01

More Indoor Space

Free up your laundry, hallway, or cupboard for storage or other appliances.

02

Reduced Risk of Water Damage

If leaks happen, they’re outside — not soaking your floors or carpets.

03

Quieter Operation

Keep noise and humming out of your living areas.

04

Easier for Future Maintenance

No need to bring tools and tradespeople through your home for servicing.

05

Ready for Bigger Systems

Outdoor units allow more flexibility if you want to upsize or switch to solar or a heat pump down the track.

How Outdoor Cylinder Installation Works

Installing an outdoor hot water cylinder involves replacing your current water heater with a weather-resistant, fully compliant outdoor unit. Here’s what to expect:
1

Free Site Assessment

We evaluate the best location on your property, considering drainage, accessibility, pipework, and compliance.

2

Plumbing and Electrical Work

Our licensed team ensures correct pipe rerouting and electrical connection to ensure compliance.

3

Install and Secure Cylinder

We install the new outdoor unit on a concrete pad with stainless steel earthquake restraints and solar UV-rated lagging for insulation.

4

Connect, Test and Commission

We connect your plumbing and power, test for leaks, and ensure safe, efficient performance — all to NZ Building Code standards.
