The heat pump is a solution frequently adopted in homes to both heat and cool rooms. Its energy efficiency is often mentioned on commercial sites and blogs. Is a wall-mounted heat pump really economical? This is the question we are going to answer through this article.

What is a heat pump and how does it work?

A heat pump is a device that acts both as a heater in winter and as an air conditioner in summer. Indeed, its design allows it to diffuse hot air during cold seasons and to cool the interior of homes during hot seasons.

The wall-mounted heat pump is composed of two units connected together. One is installed on the wall inside your home, while the other is installed outside. The latter extracts the outside air, heats it or cools it and expels it into the house using fans.

The heat pump is effective in heating up to temperatures reaching -10 to -15°C. Below this limit, you need a boiler to properly heat your property.

Energy savings depending on several factors

A wall-mounted heat pump can save up to 50% in your energy bills. However, this effectiveness depends on a number of factors, including the following.

Insulating your home

Insulation plays an important role in optimizing the performance of your heat pump. Indeed, a poorly insulated house will observe temperature leaks, which will affect your energy efficiency. First, you need to assess your insulation before buying and installing a heat pump.

The outside temperature

As mentioned above, the effectiveness of a heat pump is limited to an outside temperature that does not fall below -15°C. If the winter in your region is extremely harsh, causing the temperature to drop beyond this limit, a heat pump will be ineffective.

The size of your home

It is important to buy a heat pump that fits the size of your home perfectly. A device that is too powerful will cost you a lot in terms of cost without being more efficient. If it is too low in power, it may not be able to heat or cool your home properly.

Regular maintenance, the secret to the efficiency and longevity of your wall-mounted heat pump

In order for a wall-mounted heat pump to effectively fulfill its role for several years, it is essential to maintain it regularly. In general, this type of device has a lifespan of at least 15 years.

For this, you need to clean the filters in the indoor unit frequently. The ideal would be to do it every 3 months. As for the outdoor unit, it has a tendency to become clogged with dust, plant debris, and insects can take refuge in it. Clean it with a low-pressure jet of water to remove all dirt and small animals. Inspect it regularly to see if cleaning is necessary or not.
