The benefits of geothermal

Quiet energy.
Lasting comfort.

The ground heats and cools your building, season after season.

How it works
From the ground to your home

Follow the heat’s path.

When heating, the liquid comes back from the ground warmer than it left; the heat pump then raises its temperature to heat the house. Colours show relative temperatures, not set values.

Make better use of energy

The heat pump moves heat instead of producing it only with an electric element. Efficiency varies with operating conditions.

Steady comfort

The ground is a steadier heat source than outdoor air. Variable capacity matches the output to the demand.

A discreet installation

With a closed underground loop, the circuit is buried and the main unit sits inside the building.

Geothermal, simply

One circuit.
Two seasons of comfort.

In winter: capture the heat

The loop’s liquid exchanges heat with the ground. The heat pump raises its temperature, then delivers it to the building, by air or by water.

In summer: carry the heat away

The operation reverses: the system takes heat out of the building and returns it to the ground, which cools the rooms.

About Calorek Technologies

Your geothermal
heat pump manufacturer.

Calorek Technologies is a Quebec manufacturer of geothermal heat pumps. We design and build variable-capacity water-to-air and water-to-water units, with particular care for comfort control and equipment integration.

Our mission: to contribute to Quebec’s energy transition by designing and building efficient, durable geothermal heat pumps suited to the demands of our climate.

Proudly made in Quebec.

Rooted in Quebec, Calorek puts local know-how to work for your comfort. Our heat pumps are designed and built here, and we help grow Quebec’s geothermal expertise.

Your questions

Before you start.

Cost, subsidies, the work, choosing a unit, winter and upkeep. Something else on your mind? Write to us.

Cost and subsidies

How much does it cost?

Hydro-Québec puts an average home at $20,000 to $40,000 installed, before subsidies. The study of your building gives the real figure.

LogisVert: how much, and who applies?

For a new geothermal system, Hydro-Québec’s LogisVert offers $750 per 1,000 BTU/h of capacity, up to $54,000. The contractor, with the right RBQ licences, applies. Amounts change: check them before you sign.

What savings can I expect?

Up to 60% on heating compared with electric baseboards, says Hydro-Québec, and more if you heat with oil. The real figure depends on the system being replaced, energy prices, the installation and how you live; our savings estimator gives a first look.

How long before it pays off?

Natural Resources Canada mentions as little as 5 years. It depends on your heating today, the loop and the subsidies.

Your home and the work

Does geothermal suit an existing house?

It can be considered in a renovation. The lot, access for the work, the heat load and the distribution system must be assessed by a professional.

Is my lot big enough?

Almost always: a vertical loop needs only one or a few boreholes 15 cm wide. A horizontal loop needs more room, but often costs less.

Horizontal or vertical loop?

Horizontal if the lot has room for trenches; vertical (a borehole) on a small lot. The study of your building decides.

Will my lawn be ruined?

The digging is filled back in and the lot restored; the lawn can take a season to come back.

Do I need a permit?

Yes, the municipality issues one for the loop. Your installer takes care of it.

I only have baseboards: is it possible?

Yes: you add ducts for a water-to-air unit, or a radiant floor for a water-to-water unit. A detailed request lets us tell you which one fits.

Choosing your unit

Water-to-air or water-to-water: what’s the difference?

A water-to-air unit delivers heating and cooling through the air. A water-to-water unit supplies a hydronic circuit, such as radiant floors or compatible air-handling equipment.

How do I choose between 3 and 5 tons?

A heat-load calculation shows the capacity required. Insulation, windows, ventilation and how the building is used all shape the choice. Our capacity estimator gives a first order of magnitude. One ton equals 12,000 BTU/h: 3 tons is 36,000 BTU/h and 5 tons is 60,000 BTU/h.

How many zones?

Up to 12 zones with the water-to-air unit, each with its own thermostat.

How it works

What is geothermal heating, in one sentence?

A few metres down, the ground keeps the same temperature all year: a closed loop of water collects that heat in winter and the heat pump raises it for your home; in summer it works the other way round.

Does it work at −30°C?

Yes. The loop runs below the frost line, where the ground doesn’t freeze, so the outdoor temperature barely matters.

Does it cool in summer?

Yes, with the water-to-air unit: the same heat pump heats in winter and cools in summer, zone by zone. The water-to-water unit is offered for heating only for now.

Upkeep and warranty

How long does it last, and what upkeep?

The heat pump lasts 20 to 25 years, the loop 50 years and more. A filter every 3 months, a technician once a year.

What warranty?

A 7-year limited warranty on the water-to-air unit.
