With an Air Source Heat Pump (ASHP) there is no need to dig, drill or have a large plot of land. Instead, the energy is collected directly from the surrounding air using an externally located air handling unit. This can be located up to 30 metres away from the outside of the building for which it is providing heating and hot water.


An Air Source Heat Pump absorbs low grade heat from the air, and raises its temperature efficiently to be suitable for space heating and/or hot water. Using proven inverter driven heat pump technology to deliver effective, low carbon heating and hot water, Air Source systems provide a simple, renewable solution that rivals traditional heating systems.


  • Helps achieve renewable energy targets
  • Capable of reducing running costs and CO2 emissions
  • Fully scalable and can work independently or in conjunction with other systems (link down to dual fuel area)
  • Optimised systems from 4kW to 688kW
  • Lower investment costs
  • No impact on the ground
  • No large plot required
  • For every 1kW of electricity fed into the Air Source Heat Pump units that we use from our suppliers (i.e. the outdoor part of the heating system), you could get approximately 3kW of heating energy. The overall system efficiency and energy savings will depend on the composition of your current heating system, satisfactory system design, installation and operational settings i.e. how you use the heating system.


There are a number of important questions to ask when buying a heat pump. Here are three very essential questions to consider.

  1. A heat pump provides all the heating and hot water needs for a property.
  2. As an MCS and RECC Installation Partner we ensure the highest standards of design and fitting.

British winters are ideal for heat pumps. With the advancements in heat pump technologies the Air Source units can remain suitable to as low as -25°C.


Heat Pumps are usually sized to accommodate normal occupancy patterns and normal weather patterns, but what happens if your property is not used conventionally? A bivalent heating system may be the answer.Heacol Ltd has developed software to integrate Air Source Heat Pumps with existing or alternative heat sources. In most cases these are pre-installed oil boilers on existing heating systems. The software allows the heat pump to run the heating for the vast proportion of the year but, when the heat pump needs additional help, it turns the boiler on efficiently maintaining an optimum temperature in the property year round.As the heat pump is in full control of the boiler, these systems are eligible for an MCS certification and grant funding. A Bivalent heat pump system can offer highly efficient heating for the vast proportion of the year and then real resilience for extreme cold or high occupancy when, or if, needed.
