Our History
From a Backyard Idea to Over 40 Years of Innovation
Back in 1980, Don Trigg saw an opportunity to help people heat their swimming pools more efficiently and affordably. He began building heat pumps specifically for pool heating, giving pool owners the freedom to enjoy a longer swimming season — or even swim year-round — regardless of the weather.
Don was a true innovator. He pioneered the use of titanium tubing in swimming pool heat pumps, helping protect systems from corrosion caused by harsh pool chemicals. This innovation set a new standard for durability and long-term performance and remains an important part of our pool heating technology today.
More than 40 years later, Hot Water Heat Pumps Ltd continues to innovate and develop energy-efficient heating and cooling solutions for New Zealand and beyond.
Our expertise and product range have grown to cover a wide variety of applications, including:
- Swimming pool and spa heating
- Underfloor heating
- Domestic and commercial hot water
- Industrial heating and chilling
- Indoor pool heating and ventilation
- Condensation control and dehumidification
- Fabric ducting and customised ventilation solutions
What started in Don's backyard has grown into a team of around 30 dedicated professionals, designing, manufacturing and supporting heat pump solutions from our Auckland facility.
Today, we remain committed to the same principles Don started with: innovation, quality, reliability and energy-efficient solutions that are built to perform.
