Air Source Heat Pumps

Many have heard of ground source heat pumps and the high efficiency levels they can offer but few have realised that air source heat pumps can also offer significantly higher levels of efficiency when compared to traditional methods of heating our homes.

Air source heat pumps are much easier to install than ground source so they are more suitable for a wide variety of properties from flats to detached houses.

An external box is fitted to your outside wall. It harvests renewable, low grade energy from the outdoor air and upgrades this into useful heat to supply a home with hot water and heating. For every 1kW of electricity used to drive the pump, you will get at least 3kW of heating energy. It can work efficiently all year round even if the outdoor temperature should drop below -15 C.

Air source heat pumps are ideal for use in a variety of house sizes or styles and its carefully developed control system is designed to work perfectly to provide hot water to either traditional radiators or under floor heating systems.

Reduced energy consumption

Energy savings of over 30% are achieved by using a heat pump with a variable flow temperature as opposed to a fixed flow temperature. When installing a heat pump with a fixed flow temperature of 45ºC, annual running costs for a three bedroom house are comparable to a traditional gas boiler. If variable flow temperature with radiators are used, the running cost savings are over 20% and even greater for under floor heating systems.

Improved level of comfort

Simple to install, cost effective for the end-user and with outstanding energy efficiency it air source heat pumps are ideal for designers, installers and users. The main benefits are:

• 30 - 50% reduction in CO₂ emissions
• Helps to achieve Level 3 of the Code for Sustainable Homes
• Easy to install - self contained unit only requiring water and electric connections
• No gas supply, flues or ventilation required
• No need for groundwork or external pumps
• Single phase power supply with a low starting current
• 3 phase option available (14kW)
• Low running costs
• Low maintenance
• Even higher running cost savings and CO₂ reductions with under floor heating systems
• Designed for domestic use
• Low noise - market leading 45dBA at 1 metre (5kW model)
• Reduced VAT to 5% for domestic applications
