Aerona Air Source Heat Pumps

Air Source Heat Pumps use basic thermodynamic principles to convert latent/sensible heat (contained within the ambient air) into heat energy that can be used to provide heating and hot water. In this respect the device can be classified as a renewable energy source because the heat in the ambient air is replenished by the sun.

There are two types of ASHP- ‘air to air’ and ‘air to water’. Air to air heat pumps release the captured energy through an air heat exchanger, which is then forced (by fan) around the dwelling through trunking, or directly into the room. Most commercial buildings use this type of heating medium. The Grant Aerona is the air to water type. Air to water heat pumps release the energy into a water circuit which is then used in a wet heating system (radiators or underfloor).

A good choice for home heating

Upward spiralling energy costs and advances in heating technology, have positioned Grant Aerona Air source heat pumps as a very realistic alternative to the conventional fossil-fuelled heating system.

Compared with other domestic heating methods, a Grant Aerona heat pump can benefit homeowners by creating annual savings on fuel bills, as it can deliver up to 5.8kW of energy for every 1kW used to run the unit (this figure is dependent upon the model and water/air temperature.  It also means that homes have a lower dependency on fossil fuels, making them less susceptible to rising fuel prices.  Home heating in the UK additionally accounts for some 30% of carbon emissions.  Grant Aerona heat pumps can help reduce the amount of these harmful gases being released into the atmosphere, therefore lowering the homes carbon footprint.

The units are available as five MCS Approved ‘single phase’ units, with outputs ranging from 6.5kW-15.5kW.

Key Features

• Exceptionally high COP’s up to 5.8.
• Factory fitted weather compensating device with dual temperature control, allowing the unit to perform more efficiently.
• Factory fitted 3kW Immersion back up, designed to operate when demand for the ASHP exceeds its stated output e.g. extreme cold weather for long periods.
• Legs ensure heat pump is protected against snow build up, leaves and flood.
• Base tray heating element to stop ice formation in cold weather conditions.
• High quality powder coated external case with condensate deflector.
• Compact design with common footprint across all models
• Two year manufacturer’s warranty, with an option to extend this to five years.
