Geothermal range · Water-to-water

The warmth of water.
Comfort everywhere.

A variable-capacity heat pump to supply your building’s radiant floors and hydronic equipment.

Radiant floors

Warm water flows through a network built into the floor.

Air handling

The unit can be paired with a suitable water-to-air exchanger.

Water preheating

Possible depending on the equipment and the layout.

Hydronic control

Heating calls are managed to match what the building needs.

Performance, dimensions and options must be checked in the model’s own specification sheet. The visual shows the product family.

Variable-capacity technology

Just the energy
you need.

The variable-speed compressor adjusts the heat pump’s output to the demand. Comfort stays steadier as the building’s needs change.

The ground loop, the controls and the distribution are sized together, so the system delivers its full efficiency.

How it works

From the ground to your home.

A loop in the ground. A water circuit in the house.

Vertical loop (borehole), horizontal (trench below the frost line) or hybrid (both). Equipment, routes and proportions simplified; every project is laid out differently.
1Capture

The underground loop picks up heat from the ground.

2Transfer

The heat pump transfers that energy to the indoor circuit.

3Distribute

Water feeds the radiant floors to heat the rooms.
