Aquathermal heating
W & WT
The W range draws heat directly from groundwater, whose temperature stays almost constant all year round, for outputs from 8 to 44 kW. Two casing sizes: one for single-compressor models up to 22 kW, and a larger one for twin-compressor models and higher outputs.
Why choose W & WT?
-
Powerful
The W range 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.
Its dedicated SPIREC exchanger removes the need for an intermediate exchanger, giving a better coefficient of performance. -
Versatile
The W 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 W range very discreet (around 50 dB).
-
Long-lasting
VIVRECO is committed to building sturdy, durable and repairable heat pumps, for genuine sustainability and greater savings. The W casing is made of powder-coated electro-galvanised steel.
-
Special functions
The VIVRECO controller fitted to the W 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.
-
Connected
Like all VIVRECO heat pumps, the W 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.

Key figures
The power of each model in kW is given in its name: the W 8, for example, delivers 8 kW. WT models have two compressors, W models one. Single-phase models end with the letter S, three-phase models with the letter T.
