Nowadays, more and more people are interested in using more efficient and environmentally friendly air conditioning systems in their homes. In this respect, heat pumps have become a very interesting alternative for many homes, especially for flats. But is it really possible to install a heat pump system in a flat, and what are the advantages of this system over other conventional air conditioning systems?

In this article we will explore the answers to these questions and analyse the possibilities of heat pumps for flats.

What is a heat pump?

Heat pumps are an increasingly popular technology because of their multiple benefits for the environment and our economy.

A heat pump is an air conditioning system that uses the energy in the air to produce heat or cold in a house or building. The heat production is based on heat pump technology, which uses energy from the outside air to heat, making it a more efficient and sustainable option than other conventional air conditioning systems.

Can a heat pump be installed in a flat?

Due to the enormous popularity of the heat pump, many people still believe that its installation is limited to houses and that it is not possible to install it in a flat.

In this sense, it is important to point out that the installation of a heat pump system in a flat is possible and can be an excellent option to improve the energy efficiency of our home. It is true that, in this case, the system must be adapted to the dimensions of the flat so that it is as efficient as possible.

Things to consider when installing a heat pump system in a flat

In order to install a heat pump system in a flat, it is important to carry out a preliminary study of our energy costs and an evaluation of the infraestructure from qualified professionals.

The installation of a heat pump system in a flat is possible provided that there is a place for the heat pump and an outside air intake. In addition, it will probably be necessary to install a hot water tank (DHW). It is important to seek permission from the residents’ association for the installation of these devices and the installation professionals will handle the approval procedures for the equipment.

Is it cost-effective to install a heat pump in a flat?

One of the disadvantages of installing a heat pump system in a flat is the payback period. As the initial investment is higher than for other air conditioning systems, the time needed to pay for the system can vary depending on the size of the flat and the use of the system.

However, in the long run, the system will always pay for itself due to its high energy efficiency and cost reduction. In addition, we will contribute to the improvement of the environment by using a technology that reduces the emission of polluting gases.

On the other hand, it is true that in houses it is easier to install solar panels that complement the aerothermal installation and contribute to greater energy savings.

The time needed to pay for a heat pump system in a flat depends on several factors, such as the size of the flat, the use of the heating and hot water system, the cost of electricity in the area and the efficiency of the installed system. On average, a heat pump system pays for itself in about 7 years.

Advantages and disadvantages

Installing a heat pump in a flat can have advantages and disadvantages. Here are some of them:

Advantages :

• Energy efficiency: One of the main advantages of a heat pump is its energy efficiency. Installing a heat pump in a flat is more cost effective than other heating and  cooling systems and it can produce up to four times more heat than the electricity it consumes.
• Lower energy bills: installing a heat pump means maximum efficiency for residents, resulting in significantly lower energy bills up to 70% less.
• Versatility: heat pumps are often more versatile than other heating sources as they can be integrate with solar panels, radiators and underfloor heating. They can also be used for hot water, heating and cooling.
• Environmentally friendly: Heat pumps use clean, renewable and sustainable energy sources and have low carbon emissions as they use natural heat sources rather than gas or electricity to produce heat, reducing running and energy costs.

Disadvantages:

• Installation cost: there is a charge for buying and installing a heat pump, and the units are already very expensive without the additional installation costs.
• Few models available for flats: Flats often have limited space, and if your flat is not on the ground floor, outdoor space is even more limited. This can limit your options when choosing a unit, and you will need to consider noise levels and the rules and regulations of your building.
• Pre-existing infrastructure if geothermal: Using a ground source heat pump requires laying underground pipes, which limits your choice of heat pump if your building does not have the structure to support it.

Recommendations

If you have a large flat, it is advisable to opt for a bibloc heat pump system, which consists of two units: one installed inside the house and the other outside. In addition, if the system is to be used to provide hot water, a third element, a domestic hot water tank, is required.

Although this type of installation has a higher initial cost, it is easier to amortize in large areas. With a larger surface area, we have to consume more energy for air conditioning, which translates into a faster return on investment.

In the case of small flats, it is recommended to install a monobloc system, i.e. a single module installed on the exterior façade.
