Air-to-air heat pump: cool and heat with ease

Are you looking for an efficient way to both heat and cool your home? Then an air-to-air heat pump might be the solution for you. In this article, you will discover the many advantages, possible disadvantages and how this versatile system works.

What is an air-to-air heat pump?

An air-to-air heat pump is a type of heat pump that allows you to both heat and cool your indoor space. It is therefore similar to a air-conditioning system, but with more options. This type of heat pump is mainly known in the form of a monoblock air-conditioning system: An air-conditioning system where there is no outdoor unit. It is very popular because of its cost-effectiveness and relative simplicity of installation.

How does an air-to-air heat pump work?

When an air-to-air heat pump heats a room, it draws in indoor air using a fan. A compressor located inside the unit compresses the refrigerant gas, raising its temperature. This heated gas then passes through a heat exchanger, transferring the heat to the air. This heated air is blown into the room, and this is repeated until when the room is at the desired temperature. Cooling a room proceeds in the opposite way.

When is an air-to-air heat pump interesting?

An air-to-air heat pump is a convenient system for temperature control, but it is important to know when it is an appropriate choice. Here are some situations when considering an air-to-air heat pump makes sense:

  • When you both heating and cooling wishes.
  • Replacement for electric heating system. If you currently have electric heating, switching to an air-to-air heat pump can save costs and be more environmentally friendly.
  • As a new central heating system. For homes without central heating, an air-to-air heat pump can be a good option, especially in smaller homes where individual temperature control in each room is desired.
  • In small and well-insulated houses. An air-to-air heat pump is efficient in well-insulated, small houses where heat retention is good.

However, there are situations where an air-to-air heat pump is less suitable, such as in poorly insulated houses, large homes where multiple (indoor) units are needed, and when there is no suitable space for both the indoor and outdoor units. In general, an air-to-air heat pump is most suitable as supplementary heating or in smaller, well-insulated homes.

  • Not suitable for all homes or situations.
  • When it is very cold outside, the efficiency is a bit lower.
  • An air-to-air heat pump cannot be connected to an existing heating system.
