One of the benefits of a heat pump is that it displaces heat instead of generating heat, which allows you to gain in energy efficiency.
Think of a heat pump as a heat transporter that constantly moves hot air from one place to another, where it is needed or not, depending on the season. Even when it is very cold outside, a heat pump is able to extract the thermal energy (heat) from the cold air and transfer it inside. When it is hot outside, it reverses directions and acts like an air conditioner, evacuating heat from your home.
Wall-mounted heat pump
A wall-mounted heat pump heats or cools a specific area of the house. It is more affordable than a central heat pump and is easier and faster to install in any home. To heat your entire home, you must have several wall units or another heating system (such as a central heat pump).
Central heat pump
A central heat pump heats and cools your entire house using ventilation channels. The temperature in all rooms of the residence is uniform and comfortable, regardless of the season. This system is more expensive than a wall-mounted heat pump and is easier to install on new buildings, since it must be integrated into all rooms of the house. With a central heat pump, no other heating or air conditioning system is required and you save a lot of energy costs.
