The MCS-approved Aerona³ is Grant UK’s third generation inverter driven air to water heat pump, with an ErP rating of A++.
The Aerona³ offers three outputs, 6kW, 10kW and 16kW, and combines design features such as weather compensation controls and a base tray heating element to prevent ice formation in cold weather conditions.
It is aimed at incorporating renewable technologies into properties when space is at a premium. Grant promises easy installation and maintenance for both installers and end users and the Aerona³ comes with a 5-year guarantee (subject to T&C’s) when fitted by an approved installer.
The company says the units boast an impressive Seasonal Coefficient of Performance (SCOP) even when external temperatures drop as low as -20°C. The HPID6 model produces 6kW at a SCOP of over 4 when tested at low temperature and average climate conditions. This means, for every kilowatt (kW) of energy used to run the heat pump over 4kW of energy is being given to the heating system in return.
The output from the Aerona³ will modulate down or up depending on the climate conditions and the demand on the heating system.
This installation of a 16kW unit was carried out on a small business unit:
The anti-vibration feet are put into position - these raise the heat pump off the ground.
The heat pump is placed onto the feet and fixed, giving the required clearance between the building and the unit.
The plumbing connections are made.
The condensate pipe is connected.
The mains electrical supply is connected and the remote controller is wired to the PCB.
The heating pipework is lagged to reduce heat loss.
