After years of perfecting our geothermal heat pump product line, finding ways to innovate and providing our customers with exactly what they wanted, we finally decided to take the leap into a new kind of heat pump. This project has been months in the making, so we’re excited to finally announce the launch of our new Nordic air to water heat pump. See what our product engineer Dan Rheault has to say about it:
This new heat pump was no small undertaking. Maritime Geothermal has dozens of models of geothermal heat pumps, but we’ve never tackled an air source heat pump before. Fortunately, we had the skills and the know-how on our team to make this heat pump a reality, and we even came up with some new features and deviations from the standard air source heat pump design that will make the air to water heat pump a superior product for Canadian climates.
The Air to Water Heat Pump Outdoor Unit
The outdoor portion of the heat pump, which we’ve named the ACE unit, has been specifically developed for harsh Canadian winters. The unit is oversized to allow it to extract heat from the winter air, even in lower temperatures. This also means the outdoor unit will be super efficient at cooling in hotter climates.
The Air to Water Heat Pump Indoor Unit
On top of that, we also realized that the traditional design an air source heat pump had some major drawbacks in cold Canadian climates, so we redesigned it to better function in harsh weather. The indoor portion of the heat pump houses all of the major electronics and components, to keep them out of the cold and reduce wear and tear on the machine. This design also makes it easier to service the heat pump during cold winter months. It can be installed in a mechanical room, attic or crawl space due to its compact size.
The Nordic ATW Series will heat water for an in-floor radiant heating system, or it can also chill water for air conditioning with a hydronic air handler. Its energy supply source is not the ground, like with geothermal heat pumps, but the air. Even though it gets its heat from a variable heat source (the air gets colder during the winter), it will still be efficient due to our unique design. We expect our air to water heat pump to have an average coefficient of performance (COP) of 3.7 at an outdoor temperature of 45°F (7°C) and a COP of 1.3 at an outdoor temperature of -5°F (-20°C).
The air to water heat pump will is available in sizes up to 6 nominal tons, so one unit can heat and cool an entire home. We’ve also added a desuperheater to our design, which will allow it to generate domestic hot water for free in cooling season and with high efficiency in the heating season.
