G for geothermal
G & GT
The G range draws free energy directly from the ground, using horizontal collectors or vertical probes, for outputs from 8 to 14 kW for the smaller models and 16 to 32 kW for the larger ones, with one or two compressors. Twin-compressor models adapt their output to heating needs, limiting the number of operating cycles for greater savings and durability. For lower outputs, see our Mini-Géo range.
Why choose G & GT?
-
Powerful
The G range comes with one or two compressors: it covers a wide range of needs and can optionally provide domestic hot water or cooling in summer. Up to 4 units can be installed in cascade for commercial buildings or large installations.
-
Versatile
The G range can be installed on any type of system (with or without a buffer tank, underfloor heating, radiators, swimming pool…). The controller, developed entirely by our team, can manage up to 10 different heating zones.
-
Quiet
Its insulated casing and a refrigerant circuit mounted on an oscillating plate with silentblocs make the G range very discreet (around 50 dB).
-
Connected
Like all VIVRECO heat pumps, the G range features WebControl technology, so it can be controlled from anywhere with a simple Internet connection, through a dedicated space in a mobile app. Our after-sales service is alerted directly in the event of a fault.
-
Special functions
The VIVRECO controller fitted to the G range can manage a back-up heating system or a domestic hot water loop, keeping the water hot even when there is a long run between the tank and the tap.
-
Long-lasting
VIVRECO is committed to building sturdy, durable and repairable heat pumps, for genuine sustainability and greater savings. The G range casing is made of powder-coated electro-galvanised steel.
