How Water Heater Heat Pump Installation Works

Installing a hot water heat pump system involves placing an outdoor compressor unit (like a heat pump for your home) and connecting it to almost any hot water cylinder. Here’s how our Christchurch-based team handles the process:
1

Free Property Assessment

We assess your site to determine the ideal location for the outdoor unit and the cylinder – factoring in noise levels, airflow, drainage, and system compatibility.

2

System Selection

We’ll help you choose the best heat pump system based on your home size, hot water demand, and budget.

3

Installation

Our licensed plumbers and electricians install the system, handle any retrofitting, and ensure everything is connected, sealed, and compliant with NZ building and electrical standards.

4

Testing and Tuning

We test your system thoroughly, configure temperature settings, and show you how to get the most out of your new energy-efficient water heater.
