Every ecoGEO+ runs on the same few ideas: a variable-speed compressor, heat and cold made together, any heat source, and a controller that runs the whole installation.
Variable speedHot waterHeat and coldControlsSourcesSolarCascadeBackup
Hot water on demand up to 149 °F, and up to 167 °F with HTR, the high-temperature mode, so the unit can serve laundries, kitchens and pools without extra heaters.
Water at the temperature that radiators, fan coils and radiant floors need.
The current refrigerant for the US market, in the whole range.
With dry coolers there is no compressor outside, only a fan and an exchanger.
A staged machine jumps between fixed steps and produces more than the building needs. An Ecoforest inverter compressor follows the demand, from 20 to 100% of its capacity, so it rarely switches on and off.

Illustrative model of one day, not a measurement. The staged machine has two steps, 50 and 100%.
A hot tank and a cold tank store the energy. The heat pump keeps each one full, one after the other. To make heat it extracts it from the ground loops, and to make cold it injects heat back into them. Four pipes reach the building.
The unit makes heating and cooling in the same moment and moves the energy from the cold side to the hot side. The ground or the dry coolers only supply or take the difference. Hot water, pools and process heat feed from the cooling load.
Ecoforest writes its own control software. The unit commands the pumps, the valves, the tanks and the sources, and it talks to the cloud, so there is no external controller to program. Pick a part to see what the unit does with it.
The unit takes heat from whatever the site offers and rejects it back when the building needs cooling. The e-source controller manages up to three sources at the same time and picks the most efficient one at each moment.
Closed loops in boreholes. The ground keeps a steady temperature all year, which gives the best efficiency and takes the least land.
Closed loops buried at a shallow depth across open land. They suit sites with space and keep drilling to a minimum.
Open loops use the water that is already there. Ecoforest has reference plants on lakes, a moat and a thermal spring.
Geothermal-style efficiency without boreholes, and at a lower first cost. Outdoors there is only an exchanger and a fan.

Photovoltaic-thermal panels make electricity and collect low-temperature heat from the same roof area.
Process water, refrigeration, server rooms or wastewater. If a building throws heat away, the plant can use it.
With a bidirectional meter, the unit knows when the panels produce more than the building uses. It moves its setpoints to store that surplus as heat or cold in the tanks and the building, and it returns to normal when the sun goes.
Example setpoints. They are the temperature of the water sent through the pipes.
Choose how many 25-ton ecoGEO+ HP units the cascade has, up to six and 150 tons, then move the demand. Each running unit stays in its most efficient range and the operating hours are balanced between them. With more than 3 units the Supervisor coordinates the cascade, and with 3 or fewer the unit’s own controller does it.
Example with six 25-ton units, 150 tons in total.
Not every climate is ideal for green energy. Heat pumps lose capacity at extreme outdoor temperatures, and not every building is the same. That is why Ecoforest’s software also controls the backup systems and the whole installation, and adapts to each case, always keeping the backup as the last resort.
