Air source heat pumps extract heat from outside air and transfer it into your home, operating like a refrigerator in reverse. The air source heat pump draws air across an evaporator containing refrigerant, which absorbs heat energy present even in cold air.
This refrigerant passes through a compressor that increases its temperature to warm your home’s heating system. What makes heat pumps a great choice is their efficiency, they can generate 3-4 units of heat for every unit of electricity consumed because they are moving heat rather than creating it.
Air source heat pumps work effectively even in cold temperatures, providing efficient heating in winter despite the outside temperatures.
We offer the complete range of Midea heat pumps, including the latest R32 and R290 models, providing game-changing heating solutions for your home.

What is an air source heat pump and how does it work?
An air source heat pump extracts heat from the outside air and transfers it into your home. Even in cold weather, the air contains heat energy that the pump can harvest. The system works like a refrigerator in reverse – it uses electricity to power a compressor that concentrates low-temperature heat from the air, raising it to a higher temperature that can be used for your home’s heating and hot water. This process is highly efficient, producing 3-4 units of heat for every unit of electricity consumed.
Do heat pumps work in cold weather?
Yes, modern heat pumps are designed to work effectively even in cold weather. The heat pumps we install can extract heat from the air even when temperatures drop as low as -25°C. While efficiency does decrease slightly in extreme cold, today’s advanced heat pumps remain effective throughout the British winter. In Sussex’s relatively mild climate, heat pumps perform exceptionally well year-round.
How much will I save on energy bills with a heat pump?
Energy bill savings depend on several factors including your current heating system, home insulation, and energy tariffs. When replacing an older gas boiler, you can typically expect savings of 10-30% on your heating bills. Replacing oil, LPG, or electric heating usually results in even greater savings, often 30-50%. During our initial assessment, we’ll provide estimates of potential savings based on your specific circumstances and current energy usage patterns.
Will I need to replace my radiators?
Heat pumps work most efficiently with lower water temperatures than traditional boilers (typically 35-55°C compared to 60-80°C for gas boilers). Whether your existing radiators need replacement depends on their size and your home’s insulation. During our survey, we’ll assess your current radiators and advise if any need upgrading. In well-insulated homes, existing radiators are often sufficient. Where needed, we might recommend larger radiators or the addition of underfloor heating in some areas to ensure optimal comfort and efficiency.
How noisy are heat pumps?
Modern heat pumps are designed to operate quietly. The outdoor unit of a typical system produces around 40-60 decibels at one meter distance, comparable to a modern refrigerator or quiet conversation. At a standard distance from neighboring properties, the noise is usually barely noticeable. The heat pumps we install feature noise reduction technology and can operate in silence modes that further reduce sound levels, particularly important during nighttime operation.
Do I need planning permission to install a heat pump?
In most cases, heat pump installations are considered “permitted development” and don’t require planning permission. However, there are some exceptions, particularly for listed buildings, properties in conservation areas, or if the installation would face a highway. We’ll advise on planning requirements during our initial assessment and help with any necessary applications. For most standard installations in Sussex homes, no planning permission is required, allowing for a straightforward installation process.
How much space do I need for a heat pump?
The outdoor unit of an air source heat pump typically requires a space of approximately 1m² against an external wall, with adequate clearance around it for good airflow (usually 20-30cm at the sides and 15-30cm above). The unit should be positioned away from boundaries where noise might affect neighbors. Indoor components vary by system type – a hot water cylinder typically needs about the same space as a standard bathroom cabinet. We’ll assess your property to identify the most suitable and discreet location for all components.
