In a building, it disappears into a closet.

An ecoGEO+ Compact in every apartment gives each resident heating, cooling and hot water, with water pipes instead of ducts. A shared ground loop or an ecoGEO+ HP plant serves the whole building.

Same house. Same day. Two kinds of heat pump.

A staged unit runs flat out, stops, and starts again all day. An inverter follows what the house needs.

What changes, for the owner and for the installer.

For you

Comfort: Rooms stay at the temperature you set. No hot and cold swings between cycles.
Silence: No start and stop, and no ducted air rushing through the house.
Savings: The unit uses only the energy the house needs at each moment.
Healthier air: Moving water instead of air means fewer drafts and less dust stirred through ducts.

For the installer and the engineer

All-in-one unit: Source and load pumps, expansion vessels, backup heater and DHW valve are built in.
Compact, simpler installs: Water pipes instead of duct runs, in a smaller mechanical room.
Any source: Closed loop, open loop, dry cooler, or a hybrid chosen automatically.
Controls built in: The heat pump is the main controller of the plant room. No external controllers.
Follows the demand: Modulation lets you reduce or remove buffer tanks.

Traditional geothermal against Ecoforest.

Comparison of a traditional geothermal system and ecoGEO+
Feature	Traditional system	ecoGEO+
Compressor	On and off, or a few stages	Full inverter, 20 to 100%
Buffer tank	Usually required	Usually not needed
Hot water, pool, ice melting	Separate equipment for each	Built in. 149 °F on demand, up to 167 °F with HTR
Pumps, vessels, controls	Bought and wired separately	Built into the unit
Air distribution	Ducts to every room	Water pipes, with an optional air handler
Room temperature	Swings between cycles	Holds steady

Questions we hear.

Is it really quiet?

Very little. The compressor is the latest generation and it changes speed instead of switching on and off, so there is no start and stop and it makes less sound. The insulation of our units is also designed to make less noise than a normal refrigerator. Sound data for each model is in the datasheets.

Do I need a buffer tank?

Most installations do not. The unit adapts to the demand of the house, so buffers can be reduced or removed.

What does it replace?

The furnace or boiler, the air conditioner, the water heater and the separate controllers. The WWA also covers pool and ice melting.

How hot can the water get?

Domestic hot water reaches 149 °F on demand, and up to 167 °F when the HTR heat recovery is used.

Does it work with solar panels?

Yes. With a bidirectional meter, the unit raises its setpoints when there is solar surplus and stores the energy as heat.

What heat sources can it use?

Closed loop, open loop and dry cooler, alone or hybrid. The unit picks the most efficient source at each moment.

Are there incentives?

The federal residential tax credit ended after 2025. State and utility programs may still apply. Your installer can check what is available in your area.

What does the warranty cover?

Compressor and inverter: five years of parts, with labor covered for the first three. Full conditions are in the warranty document. Draft Current terms to be confirmed before launch.
