Understanding the Technology

What Are Water/Ground Source Heat Pump Units?

Simply put, Water/Ground Source Heat Pump Units are smart machines. Additionally, they work like a refrigerator in reverse. Instead of keeping things cold, however, they can both heat and cool your building.

"The EPA says geothermal heat pumps can cut energy use by up to 70%. This makes Water/Ground Source Heat Pump Units one of the best green energy choices."

— EPA Environmental Protection Agency
How It Works

Year-Round Heating & Cooling Cycle

In Summer

Building → Ground

The system takes heat from your building. Then, it sends that heat into the cooler ground.

Cooling Mode
In Winter

Ground → Building

The system pulls heat from the ground. Next, it brings that heat into your building.

Heating Mode
Year-Round

Steady Ground Temp

The ground temperature stays steady. Therefore, these systems work great all year.

Consistent Performance

Technology

What Are Water / Ground Source Heat Pump Units?

These systems extract low‑grade thermal energy from underground loops or open‑water sources and amplify it for space heating, cooling, and domestic hot water — all from a single, highly efficient unit.

Water Source Heat Pump Unit COP up to 5.5

Efficient, Renewable, Versatile

Unlike air‑source systems that lose efficiency in extreme weather, water/ground source heat pumps maintain consistent performance because subsurface temperatures remain stable year‑round — typically 10 – 16 °C regardless of outdoor conditions.

EPA: "Geothermal heat pumps are among the most energy‑efficient and environmentally clean heating and cooling systems available."
— U.S. Environmental Protection Agency

How It Works

Summer — Cooling Mode

Extracts heat from indoor spaces and rejects it into the ground or water loop, providing efficient chilled water for comfort cooling.

Cooling

Winter — Heating Mode

Reverses the cycle: absorbs stable ground/water heat and amplifies it to deliver hot water for radiators, floor heating, or AHUs.

Heating

Year‑Round — Consistent

Because ground and water temperatures stay constant (10 – 16 °C), the heat pump delivers reliable COP up to 5.5 regardless of season.
