Grant Internal Volumiser - 50 Litre

Grant Internal Volumiser - 50 Litre

The Grant 50 Litre Internal Volumiser (HPIDVOL50) is designed to increase the water volume within a heating system, helping compatible Grant Aerona air source heat pumps meet the minimum system volume requirements specified by the manufacturer. With its insulated construction and compact cylindrical design, the volumiser is suitable for internal installation on a suitable floor or flat surface. It provides a practical way to add additional system water capacity while also incorporating a built-in immersion heater for additional heating support when required.

Durable and Well-Insulated Construction

The volumiser is manufactured from welded stainless steel and features 50mm of polyurethane foam insulation. The insulated tank is housed within a cylindrical galvanised steel outer casing with a powder-coated finish, providing a robust and practical solution for heating system installations. The vessel has a single inlet on the side and an outlet at the top. Both connections are 1" BSP female fittings, making it straightforward to incorporate into a compatible heating system.

50 Litre Additional System Volume

With a 50-litre capacity, the Grant Internal Volumiser helps increase the overall volume of water within the heating system. This can be particularly important when installing an Aerona air source heat pump in a system where the existing water volume does not meet the manufacturer's minimum requirement. Adding the appropriate system volume can help support the correct operation of the heat pump and ensure the installation meets the relevant system requirements.

Built-In 3kW Immersion Heater

A 3kW electric immersion heater is factory-fitted to the side of the cylinder. This provides an additional source of heat that can be used when required, including as a backup heat source or to assist with heat pump defrosting. The immersion heater can be controlled using a Grant Immersion Relay (HPIDSMARTIMM), either through a compatible Grant Aerona Smart Controller or the Grant Aerona³ air source heat pump to which the volumiser is connected.

Installation Requirements

The Grant 50 Litre Internal Volumiser is designed for indoor installation and should be positioned on a suitable floor or other flat surface capable of supporting the weight of the vessel when it is full. Before installation, make sure there is sufficient space and that the supporting surface is suitable for the fully filled unit. Installation should be carried out in accordance with the manufacturer's instructions and by a suitably qualified heating professional.
