Grant Aerona³ accessories

Grant Aerona³ accessories

Grant supply a range of accessories which are compatible with the Aerona³ air source heat pump and VortexAir Hybrid ranges. Each accessory is designed to complement the operation of Grant heat pumps.

Features & benefits

  • The flexi-foot kit with fixings comprises of two 600mm feet. The Aerona³ unit is mounted onto the feet to raise the heat pump off the group while also serving as anti-vibration. (Please note, when installing a VortexAir Hybrid with both the boiler and heat pump sited together externally, two kits will be required totalling four feet)
  • Three sealed system kits are available in 12 litre, 18 litre and 50 litre sizes to suit all Aerona³ heat pump models
  • The through wall insulation kit includes insulation to fit the heavy duty 22-28mm flexi hoses used with the Aerona³
  • The Hot Water Priority (one or two zones) Relay gives hot water priority over the central heating system – it allows the cylinder to fill with hot water when there is a hot water demand and when this is satisfied, the relay allows the heat pump to return to providing space heating
  • The Hot Water Priority (up to four zones) Relay is for use on heating systems with two central heating zones, such as one upstairs and one downstairs – this up to four zone hot water priority relay enables the hot water demand to be prioritised over two central heating zones instead of one
  • The Grant 7 day immersion programmer automatically switches on the cylinder’s immersion element short a short period of time either daily or weekly to heat the water to the temperature required to provide anti-legionella protection (this programmer should be fitted with every heat pump/cylinder installation)
  • The Domestic Hot Water Programmer controls the heat pump's domestic hot water operating periods automatically
  • The EP001 wiring centre is ideal when more than one zone needs to be connected to a heat pump as it simplifies the wiring associated with multi-zone heating systems
  • Grant also supply a System Combined Volumiser/Low Loss Header which helps maintain correct flow rate through the heat pump and can provide suitable volume of system water. If there is no room inside for the Combined Volumiser/Low Loss Header, a 30 Litre External Volumiser can be supplied which sits behind the heat pump to provide suitable volume for the system water
  • Installers requiring the part codes for the accessories listed above should visit the Professionals heat pump accessories webpage
