Maritime Geothermal Ltd

Maritime Geothermal Ltd. is the brains behind the Nordic® brand of heat pumps. We make high quality heat pumps that:

Are the perfect choice for sustainable home heating and cooling.
Are eco friendly.
Will reduce your monthly utility bills by up to 60%.
When you choose to buy a Nordic® heat pump, you’re choosing to support a Canadian company and helping make the world a more sustainable place.

We manufacture Nordic® heat pumps at our facility in Petitcodiac, New Brunswick. Our highly trained and experienced Nordic® team members design, test and build both residential heat pumps and commercial heat pumps in-house.

We strive to make the world a more sustainable place, and this mantra has guided us throughout our 30-year history. Beyond manufacturing the most eco friendly home heating and cooling equipment on the planet, we also power our facility with green power, and invite the public to use our electric car charging station free of charge.

Incorporating geothermal heating in commercial buildings is becoming an increasingly popular option, and it’s easy to see why. Geothermal heat pumps are eco friendly, they provide a comfortable, reliable heat and the economic benefits mean your building will have low operating costs for decades.

How Geothermal Heat Pumps Work in a Commercial Building

Geothermal heat pumps operate on a simple principal: they move heat from one place to another via a refrigeration process. In a commercial building, a series of heat pumps removes heat from an energy supply source in the ground. The heat pump concentrates this low-grade heat, raising its temperature and then transfers it to the building’s energy distribution system (usually radiant in-floor and hydronic fan coils) via a heat exchanger. In the summer, the process is reversed. The heat pumps collect heat from the building and deposit it into the ground loop, providing cooling.

Geothermal Heating Works in Any Commercial Building

Our commercial heat pumps have been installed in a variety of applications including schools, nursing homes, police stations and farmers’ markets. Many of these buildings are LEED certified and valued in the millions of dollars. Over the past several decades as commercial heat pump installations have become more popular and thus more standardized, a generally accepted typical implementation has emerged for commercial installations.

Geothermal heat pumps need a collector system, just like a water well pump. You could set a water pump on your desk and turn it on, but it won’t pump water unless it is connected to a source. In your geothermal system’s case, the source is a vertical borehole loop field that is located under a parking lot or recreational field. The heat is removed from the loop field and transferred to the building via a series of Nordic® Commercial W Series heat pumps.

Finally, the heating is delivered via large-scale radiant in-floor heating, and cooling is delivered via hydronic fan coils. The design of the ground loop and distribution system, and the number of size of heat pumps can be modified depending on your specific building’s footprint and layout so that commercial geothermal will work in any commercial building.

The Nordic® Commercial W Series is the Right Choice

The Nordic® Commercial W Series is available in a wide variety of sizes, allowing them to be configured to precisely suit the needs of your building. We work closely with system designers to help create a heating and cooling system that will maintain optimum comfort, achieve low operating costs, and require little maintenance.

Geothermal heat pumps are highly efficient. In fact, they are the most efficient heating and cooling equipment on the market today. This is because they simply move heat from place to place, instead of generating it from a fuel source like oil, natural gas or electricity. For example, for every watt of electricity you buy, electric heating systems generate 1 watt of heat. Geothermal heat pumps, on the other hand, move 4.1 watts of heat energy into your building for every watt of electricity used. This means geothermal heat pumps have a coefficient of performance (COP) of 4.1, compared to electricity, which has a COP of 1. This efficiency will allow you to save huge amounts on your monthly utility costs.
