What is an air source heat pump?

An air source heat pump is a device that uses the outside air to provide heating and cooling for a home or building. It works by transferring heat from the outside air into the building, using a refrigerant-based system. The heat pump can absorb heat from the outside air even when temperatures are as low as -15°C, making it an efficient and cost-effective way of providing heating and cooling all year round.

What are the benefits of Panasonic heat pumps?

Panasonic heat pumps offer a range of benefits, including:

Energy efficiency

  • High COP, even at low temperatures (up to 5,08 for 5kW)
  • Energy efficiency class A+++
  • “A” rated energy class water circulation pump with variable speed


  • High heating and cooling capacities
  • Space saving:
    • 1 fan outdoor unit
    • No indoor unit
  • Cooling mode down to +10 °C outdoor
  • In installation:
    • No refrigerant connections (sealed refrigerant circuit)
    • Magnet filter built-in
    • 6L expansion vessel built-in


  • Heating curve down to -20ºC
  • Operation range down to - 20ºC outdoor
  • 60ºC water outlet temperature
  • Low noise levels
  • Efficient or comfort mode for DHW: Part load for better efficiency or full load to reduce the heat up time

Control & Connectivity

  • Optional Aquarea Smart and Service Cloud
  • Optional integration into BMS projects
  • New smart functions:
    • SG ready for heating, cooling and DHW modes
    • Utility remote bivalent control: By dry contacts
    • Stop external device when defrost by Dry contact (for fan coil fan stop)

What is the life expectancy of an air source heat pump?

The life expectancy of an air source heat pump can vary depending on the model and how it is maintained. Generally, a well-maintained heat pump should last for up to 15 years or more. However, some models may have shorter lifespans due to their design or the environment in which they are installed.

Regular maintenance and servicing of your heat pump can help extend its lifespan and ensure it continues to operate efficiently. It is important to check the manufacturer’s instructions for specific maintenance requirements for your particular model of heat pump.

Do you need bigger radiators with an air source heat pump?

Yes, you may need bigger radiators with an air source heat pump. This is because the air source heat pump works by transferring heat from the outside air into the building, which requires more energy than a traditional boiler system.

As a result, larger radiators are needed to ensure that the heat is distributed evenly throughout the home.

How much space do you need for an air source heat pump?

The amount of space needed for an air source heat pump will depend on the size and type of system you are installing. Generally, a larger system will require more space to accommodate the outdoor unit and any additional components, such as pumps or tanks.

It is important to consider the size of your garden or outdoor area when deciding on the size of your heat pump, as this will determine how much space is available for installation.

Additionally, it is important to factor in any potential obstructions, such as trees or buildings, that may affect the placement of the outdoor unit. If you have limited space, there are smaller models available which can be installed in tighter spaces.

Are Panasonic heat pumps noisy?

No, Panasonic heat pumps are designed to be quiet and efficient. The Panasonic range of heat pumps are specifically designed to be as quiet as possible, with very low noise levels. Additionally, the outdoor unit is designed to be unobtrusive and blend in with its surroundings. With a Panasonic heat pump, you can enjoy comfortable temperatures without having to worry about excessive noise leve
