Bringing Warmth to South Island Homes
We’re UK-trained central heating specialists with over 70 years of combined hands-on experience. When we moved to New Zealand, we noticed many homes in Christchurch and across the South Island struggling with heating that couldn’t handle winter. That’s why we created Polar Energi NZ, based in Christchurch and servicing Ashburton, Queenstown, Greymouth, Westport, and surrounding areas, bringing proven European-standard warmth to Kiwi homes with reliable systems that keep every room comfortable, even on the coldest nights.
We personally design and install hydronic underfloor heating, radiator systems, diesel boilers, hot water cylinders, and heat pumps for both residential and commercial projects. No middlemen and no shortcuts, just two experienced professionals who care about doing the job properly and delivering efficient, long-lasting heating suited to South Island conditions.

What Our Customers Say
If I could give more stars I would, what’ a great company to deal with.
John came out to look at a problem with our underfloor heating other companies failed to rectify, John took one look at it and said it was programmed incorrectly since day one about seven years
Jessie Jones
Thanks John and the team at Polar Energi, our heating system is awesome!
We’re very happy about the system’s efficiency and low running costs, given that it provides heating for our two storey home and all our hot water needs.
