How to ensure the correct operation of heat pumps? Servicing/regular maintenance.

The last two years have seen an increase in interest in heat pumps for home heating. The need to replace old, classless boilers by September 2024 as a result of the anti-smog law and the attractive subsidies are the reasons for choosing this environmentally friendly heat source. Although their operation is not complicated, it is worth familiarising oneself with the important issues in order to ensure that they operate without fail and with the greatest possible efficiency.

What can cause a malfunction heat pumps?

Many factors influence the trouble-free operation of the entire system. Malfunctions can occur both at the installation stage and during operation. Of course, the first prerequisite is the correct installation of the pump. It is worth remembering that there is no shortage of people on the market offering heat pump installation services at a cheaper price. Often, this involves little experience and insufficient knowledge, the consequence of which may be an incorrectly executed installation, which may translate into increased energy consumption or failures in the future.

Another factor that adversely affects the operation of the system may be incorrectly set operating parameters. Changing the pump parameters on your own can lead to inefficient operation of the unit. Therefore, it is better to leave the setting of the pump to a specialist, as in this case it is very important to know the internal automation of the unit. Changing one parameter can also affect other functionalities.

The most important but critical component of a heat pump-based heating system is the compressor. This It plays a key role in the heat pump and the life expectancy and efficiency of the entire system depends on its efficiency and optimum operation.. This device is responsible for heat accumulation of the refrigerant. The reason why the compressor can be particularly vulnerable is because it is switched on and off too frequently, which consumes and overheats the compressor and consumes more energy unnecessarily. This is usually caused by an incorrect selection of the heat pump in relation to the heat demand of the building or a lack of a suitable buffer.

Steps to avoid damage to the heat pump

The user of the unit is responsible for the correct operation of the heat pump. It is to his or her advantage that the pump operates correctly and avoids any faults that could lead to unnecessary costs. A way to avoid problems is to perform regular inspections. Periodic inspections are a kind of prevention. Heat pump maintenance and servicing are aimed at looking after the unit, extending its service life and optimising its operation, which can result in reduced energy bills.

When to perform the first technical inspection of the heat pump?

The first servicing of the heat pump must be carried out within the period indicated in the warranty. Normally, this mandatory service is performed before the first year of operation. Based on several months of observation of the system's operation, any changes to the parameter settings can be made and the mode of operation can be better adapted to the conditions of the building. In addition, if mistakes are made during installation, an inspection will help to detect these and thus prevent subsequent, potentially serious heat pump malfunctions. In the long term, it is recommended that users have the heat pump serviced annually.

Who do you contract to service your heat pump?

The inspection of the pump should be carried out by a suitably qualified person - a representative of the manufacturer of the equipment being checked or a member of the heat pump brand's authorised service team. It is worth noting that failure to inspect the pump on time will result in the loss of the manufacturer's warranty, so it is worth remembering.

How is the heat pump inspection carried out?

A heat pump service involves assessing the efficiency of the unit. During the inspection, the service technician assesses both the lower and upper heat source as well as the operation of the unit itself. During the inspection, the service technician checks, among other things:

• compressor operating parameters
• the tightness and pressure of the refrigeration system
• refrigerant level
• condition of filters and other heat pump components
• installation pressure
• safety valves
• analysis and control of the electrical installation

After the service, the service technician prepares a report, i.e. a record of the visit. In it, he/she includes all information on the basic parameters of the appliance and any discrepancies.

How often do I need to have my heat pump serviced?

Periodic maintenance of heat pumps should be carried out as often as indicated in the unit warranty. This is usually no less than once a year, although some manufacturers - such as Mitsubishi - require an inspection twice a year. The best time to visit a service technician is at the beginning of autumn, i.e. before the heating season starts.

To ensure that the service has been carried out correctly and that the guarantee is maintained, it is best to turn to manufacturer-authorised service. It is advisable to go to a proven service technician who is knowledgeable and experienced in their trade.

Summary

The above article describes the important aspects of heat pump servicing, which are key to maintaining efficiency and sustainability. The main conclusions of the article are:

• Need for regular servicing - heat pumps require regular servicing and maintenance, to maintain high efficiency it is recommended that servicing is carried out at least once a year.
• Detecting potential faults - prompt intervention can prevent serious failures. The service technician should be able to identify any potential faults or problems that may require repair.
• Long service life: Correct operation and servicing of a heat pump can significantly extend its life, which ultimately translates into savings for the user.
• The need for professional servicing: The article points out that heat pump servicing should be carried out by qualified technicians who are certified and experienced.

In conclusion, the article highlights the importance of regular servicing of heat pumps to maintain their efficiency and longevity, which translates into energy savings and long-term benefits for users.
