How Indoor Hot Water Cylinder Installation Works

Whether you're upgrading an existing cylinder or installing a new one, we follow a proven process to ensure performance and peace of mind:
1

Free Site Assessment

We assess the best location (typically in a laundry, hallway cupboard, or under the house) and review access, ventilation, and compliance requirements.

2

Plumbing and Electrical Work

Our licensed plumbers check the pipework, valves, and tapware to ensure they suit the pressure rating of your chosen system.

3

Install and Secure Cylinder

We safely disconnect and remove the old unit, including disposing of it in an eco-friendly way.

4

Connect, Test and Commission

We install your new cylinder, connect it to power and plumbing, and ensure all safety valves, tempering systems, and insulation are correctly fitted. Every installation is tested and compliant with NZ Building Code standards.

We Supply Trusted, Reliable Brands

We install and recommend NZ-compliant cylinders known for their performance and durability. All units come with full warranties, manufacturer support, and Hot Water Shop’s expert installation.
