ATW Nordic Heat Pump Collection - Air to Water, Split Type

Our air- to- water heat pump system provides an alternative to a traditional air heat pump. These water-cooled heat pumps extract heat from the outdoor air in winter and reject heat outside in the summer—without the need for a ground loop. The Nordic heat pumps from the ATW Series are available in sizes from 2 to 6 nominal tons, for whole-home applications, and operate down to -7°F (-21.7°C) at which point back-up heating is required.

This streamlined design significantly reduces installation costs, making it an affordable and efficient heating and cooling solution for both residential and commercial applications.

Nordic® Air to Water Heat Pump

Our water cooled heat pump, part of the ATW Series, efficiently heats water for in-floor radiant heat and cools water for air conditioning through a hydronic fan coil. We have made significant modifications to enhance the performance of our air source heat pumps, ensuring reliable operation even in harsh winter conditions.

To excel in colder outdoor temperatures, our water cooled heat pump features an oversized outdoor unit for superior heating performance. Additionally, intelligent defrost logic minimizes energy consumption during outdoor coil defrost cycles. Furthermore, the compressor section is housed indoors, safeguarded from inclement weather conditions.

By using a Nordic air-to-water heat pump, you gain:

  • Lower energy bills – Efficient heating and cooling means reduced energy consumption.

  • Year-round comfort – Seamless heating in winter and cooling in summer with a single system.

  • Sustainable technology – Lower carbon footprint compared to fossil-fuel-based heating.

  • Durability and reliability – Built with high-quality components like a dual-stage scroll compressor and a coaxial accumulator to ensure long-term performance.

Whether you need a reliable heating system for your home or an energy-efficient solution for your business, our Nordic heat pumps provide outstanding performance and long-term savings.
