  • Sealed system kits are available to suit all Aerona³ heat pump models and they are available in three sizes: 12 litre, 18 litre and 50 litre
  • The flexi-foot kit with fixings is supplied in a pack comprising of two 600mm feet for mounting the Aerona³. The kit serves as anti-vibration as well raising the heat pump off the ground. When installing these with a VortexAir Hybrid when both the boiler and heat pump are sited together externally, two kits will be required totalling four feet.
  • The through wall insulation kit is a heavy duty insulation to fit the 22-28mm flexi hoses used with the Aerona³.
  • Hot Water Priority Relay (up to two space heating zones): this relay gives hot water priority over the central heating system. When there is a demand, the Hot Water Priority Relay will automatically close the valve to the heating system to allow the hot water cylinder to be heated using the heat pump’s full output. When the hot water demand is satisfied, the Relay allows the valve to the heating system to open and the heat pump returns to providing space heating as required.
  • Hot Water Priority Relay (up to four space heating zones): for heating systems with two central heating zones (such as one upstairs and one downstairs), Grant supply this up to four zone hot water priority relay which enables the hot water demand to be prioritised over two central heating zones instead of one.
  • Grant’s 7 day immersion programmer automatically switches on the cylinder’s immersion element, either daily or weekly, for a short period of time, taking the water up to the required temperature set by the immersion thermostat to provide anti-legionella protection. 
  • Domestic Hot Water Programmer: this automatically controls the heat pump domestic hot water operating periods. The integrated timer provides up to four on/off periods per day.
  • The Grant System Combined Volumiser/Low Loss Header creates hydraulic separation therefore maintaining the correct flow rate through the heat pump while providing a suitable volume of system water to allow the heat pump to fully modulate. Includes 3kW supplementary element and relay.
  • If the Combined Volumiser/Low Loss Header cannot be fitted inside, a 30 litre External Volumiser can be supplied to sit behind the heat pump. Connected to the flow from the heat pump into the flow of the system, this volumiser provides a minimum volume of water to allow the heat pump to control its modulation and it comes complete with 3kW supplementary heater and relay.
  • Grant's EP001 wiring centre centralises the wiring for up to four heating zones and one domestic hot water zone providing a convenient solution for Multi-zone wiring.
