NIBE VVM S320 is an indoor module for compatible NIBE air-to-water outdoor heat pumps. It combines controls, domestic hot-water storage and several hydraulic and electrical components in one cabinet. It is not a heat pump on its own.
What is included
VVM S320 contains a water heater, electric supplementary heat, a self-regulating circulation pump, filling valve, pressure gauge, safety valve and expansion vessel.
Actual cylinder volume is 178 litres, producing 240 litres of mixed hot water at 40°C under the specified test basis. NIBE UK markets the product as a 200-litre-class hot-water solution. One figure is the technical volume and the other is a rounded product class.
Published cabinet dimensions are 1,800 mm high, 600 mm wide and 615 mm deep, with a net weight of 141 kg.
Compatibility and specification
Compatibility is specific to the NIBE outdoor model, software and accessory arrangement. VVM S320 is an indoor module, so the compatible outdoor heat pump remains a separate part of the system.
It therefore remains one component of a larger NIBE air-to-water system.
