DistributionForced air

Forced-air distribution

Heating and cooling travel through your ducts.

Matched ventilation

The airflow follows what the system needs.

Zoning

Compatible controls set the comfort room by room.

New build or renovation

New house or existing system: each integration is reviewed case by case.

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. Comfortable air in every room.

1Capture

The underground loop picks up heat from the ground.

2Transfer

The heat pump transfers that energy to the indoor circuit.

3Distribute

The ducts carry heated air to the rooms.

And in summer?

The cycle reverses: the heat pump removes heat from the indoor air and transfers it to the ground. The same ducts deliver the cooled air.
