The Top-Rated Home Heating System
Choosing the right home heating system has never been more important for homeowners in Canterbury. With power prices on the rise, growing climate concerns, and a bigger focus on long-term efficiency, Kiwi homeowners are looking for solutions that don’t force them to choose between comfort, savings, and sustainability. A recent large-scale study comparing 13 different home heating systems has delivered a clear result.

The Clear Winner: Air-to-Water Heat Pump + Solar
According to research highlighted by the Technical University of Munich, the most efficient, cost-effective, and environmentally friendly home heating setup is:
An air-to-water heat pump paired with photovoltaic (PV) solar panels (link).
The study assessed performance across emissions, lifetime costs, and overall efficiency — even when economic conditions weren’t ideal. The outcome was clear.
How Does It Stack Up Against Boilers?
When compared with traditional boiler systems (i.e. gas or diesel boiler), the air-to-water heat pump and solar combination delivered (the numbers below are based on gas boilers):
17% fewer carbon emissions
6% lower lifetime costs
Strong performance even when energy prices were high and conditions were tougher
In short, this system doesn’t just perform well on paper — it’s built to last, future-ready, and delivers real savings over time.

Why Do Air-to-Water Heat Pumps Work So Well?
PV Solar Panels
Air-to-water heat pumps draw heat from the outside air and transfer it into water for:
Space heating, including radiators and underfloor systems
Hot water for everyday household use
When paired with solar PV panels, much of the energy needed to run the system can be generated by the sun, helping to significantly reduce both power bills and carbon emissions.
It’s a great option for homeowners who want:
Lower ongoing energy costs
A smaller environmental footprint
A modern heating solution that fits with New Zealand’s clean energy future.
