How Hot Water Heat Pump installation works

Installing a hot water heat pump system involves determing whether your home would suit an integrated or split unit. Here’s how our Christchurch-based team handles the process:

Free property assessment

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

System selection

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

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.
