Grant Aerona accessories

Features & benefits

• The flexi-foot kit with fixings comprises of two 600mm feet. The Aerona 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 Aerona heat pump models
• The through wall insulation kit includes insulation to fit the heavy duty 22-28mm flexi hoses used with an Aerona heat pump
• The Hot Water Priority (up to two space heating zones) Relay, suitable for Aerona³ R32 models only, 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 space heating zones) Relay, suitable for Aerona³ R32 models only, 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 (suitable for Aerona³ R32 models only) 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 (suitable for Aerona³ R32 models only) controls the heat pump's domestic hot water operating periods automatically
• The EP001 wiring centre (suitable for Aerona³ R32 models only) is ideal when more than one zone needs to be connected to an Aerona³ R32 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 for the Combined Volumiser/Low Loss Header, a 30 Litre External Volumiser can be supplied (for Aerona³ R32 models only) which sits behind the heat pump or 50 Litre Internal Volumisers (compatible with all Aerona models) are available to provide suitable volume for the system water
