Understanding Commercial Air Source Heat Pumps
Commercial air source heat pumps, also known as commercial ASHP’s (Air Source Heat Pumps), are sustainable, cost-effective solutions for heating and cooling commercial properties. They use the outside air to provide energy-efficient temperature control for commercial applications. They’re suitable for a wide range of property types and purposes, including:
Large industrial spaces
Commercial air source heat pumps enhance energy efficiency, decrease operational costs, and improve environmental sustainability and decarbonise, leading to reduced energy bills. To determine a building’s suitability for a commercial air source heat pump, considerations should include existing radiators and temperature requirements, particularly in commercial premises.
When installing heat pumps in commercial heating applications the heating contractor should comply to the MCS scheme, which is a UK-wide programme called the Microgeneration Certification Scheme (MCS) that certifies microgeneration installers, guaranteeing safe, effective, and regulatory-compliant installations. A variety of renewable energy technologies are covered under the programme, such as wind turbines, solar panels, and heat pump systems (both air source and ground source heat pump).
How Air Source Heat Pumps Work
Air source heat pumps:
Extract heat from the outside air to warm buildings and provide hot water.
Can also function as air conditioners during warmer months.
Air source commercial heat pumps operate similarly to a refrigerator, but in reverse, using the ambient heat from the outside air as the heat source.
Utilise heat pump technology and electricity.
Compress and circulate a refrigerant to extract heat from the external air and dispense it inside.
Provide heating and hot water efficiently.
Their dual functionality classifies them as a hybrid heating system, acting as a single solution for heating and cooling systems in different climates.
Components of an Air Source Heat Pump
The key components of an air source heat pump include:
The heat exchanger
The purpose of the expansion valve is to regulate the flow of refrigerant in the system.
These components work together to transfer heat energy from the air to the building. The compressor raises the pressure and temperature of the refrigerant gas, enabling effective heat transfer with high efficiency.
The heat exchanger transfers heat from the air to a fluid, which then passes through the heat exchanger, raising the temperature of the fluid and transferring the heat to hot water for heating purposes.
The expansion valve manages the flow of refrigerant gas between the condenser and evaporator, optimising the efficiency of the heat pump and helping businesses reduce their carbon emissions or carbon footprint.
Benefits of Commercial Air Source Heat Pumps
Commercial air source heat pumps, also known as commercial heat pump systems, offer numerous benefits, such as improved energy efficiency, reduced operating costs, and a lower environmental impact compared to traditional heating systems and water source heat pumps. They operate at an efficiency rate of between 300 and 400%, significantly higher than traditional heating systems powered by fossil fuels.
Their lower maintenance costs, compared to gas boilers, contribute to the total savings on service and upkeep of a gas boiler.
Often used in conjunction with our heating and cooling units which are ideal for commercial buildings such as warehouses, factories, supermarkets, car show rooms etc.
Air source heat pumps are highly energy-efficient, using less electricity than conventional heating systems and reducing overall energy consumption. Their Coefficient of Performance (COP) represents their efficiency in converting electrical energy into heat, with values typically ranging from 2.5 to 4.0. This is notably higher than traditional heating systems, such as electric resistance heaters, which have a COP of 1.
Air source heat pumps maintain high energy efficiency during variable weather conditions by extracting heat from the external air and using it to heat the commercial buildings, even in cold weather.
Commercial air source heat pumps allow businesses to save on energy bills and enjoy a solid return on investment, potentially saving thousands of pounds annually. Several factors can affect cost savings, including:
Size and efficiency of the heat pump
Overall fuel cost savings
The initial cost of the heat pump
The size of the business premises directly correlates with the cost savings from commercial heat pumps for space heating. Therefore, sizing the heat pump system accurately according to the size of the commercial building optimises cost savings and fuel bills.
Commercial air source heat pumps, as well as ground source heat pump systems, utilise renewable energy sources and produce fewer greenhouse gas emissions, contributing to a more sustainable and greener future. Studies have shown that employing air source heat pumps in non-domestic buildings can result in a reduction in carbon emissions of up to 65-70% compared to traditional gas boilers or direct electric heating systems.
Global implementation of heat pumps in place of traditional boilers could cut global CO2 emissions by 3 gigatons annually for HVAC systems.
Factors to Consider When Choosing Air Source Commerical Heat Pumps
Selecting a commercial air source heat pump requires consideration of factors like the building temperature requirements, insulation levels, and the associated installation and maintenance costs in commercial applications. These factors can affect the heat pump’s overall efficiency and cost-effectiveness, necessitating their evaluation before a decision is made.
Commercial properties have diverse temperature needs, hence the need to select a heat pump capable of meeting these requirements efficiently. Our commercial ASHP range can operate with outdoor ambient air temperatures ranging from minus -25°C to plus 45°C.
Selecting an air source heat pump capable of meeting the demand at a range of outdoor air temperatures is important, as is consulting with manufacturers or mechanical consultants to identify the most suitable commercial air source heat pump for a specific air conditioning application.
Installation and maintenance costs
The varied installation and maintenance costs of commercial air source heat pumps warrant consideration in the decision-making process. The installation process of a commercial air source heat pump can significantly impact its overall cost given that the initial outlay for purchasing and installing a heat pump tends to be higher than for conventional heating solutions,especially when it comes to ground source heat pumps, for example.
Our Commercial Air Source Heat Pump Range
Maximizing the ratio of heating or cooling energy to electricity drawn from the network is a priority in unit design. Commercial heat pumps work more effectively when the coefficients COP (heating) or EER (cooling) are higher. The higher these coefficients, the more effectively commercial heat pumps work.
We can cascade up to 8 units, so a maximum of 596.8 kW at 45C flow temperatures, the maximum in a single unit is a 74.6 kW heat pump.

UK Government Incentives and Support for Commercial Air Source Heat Pumps
Government incentives and support programs like the Boiler Upgrade Scheme (BUS) can aid businesses in reducing the costs of installing commercial air source heat pumps and encourage the embrace of environmentally friendly heating solutions and help reduce climate change.
The Renewable Heat Incentive (RHI) was a government incentive and support program designed to encourage the uptake of renewable heat technologies (This has now closed as at the 31 March 2022 and is superseeded by the new boiler upgrade scheme. The Boiler Upgrade Scheme provides up to £7,500 towards installation costs for low carbon heating systems in commercial and non-domestic properties. These programs can assist businesses with the cost of installing commercial air source heat pumps and promote the use of environmentally-friendly space heating solutions.
