Buffer tank VPA

Product overview
The NIBE VPA is a double-jacket hot water tank and accumulator tank with a large internal water volume, designed primarily for connection to heat pumps and other heat sources. The inner tank is protected by a copper or enamel corrosion-resistant coating and is rated for operating temperatures up to 90°C. The unit includes a socket for an immersion heater and a tube for a temperature sensor. Insulation is detachable and environmentally friendly to simplify installation and minimise heat loss. The VPAS 300/450 variant incorporates a copper finned coil (2.3 m²) for integration with solar thermal systems up to approx. 15 m² of collector area.
