Heat pumps – are they really the best solution for companies?

Heat pumps are often presented as a modern solution that can help companies reduce energy consumption and protect the environment. They have many advantages, but they are not without disadvantages that should be considered before deciding to implement them. In particular, companies operating in colder climates such as Poland and Germany may face certain restrictions. Here is an overview of the advantages and disadvantages of heat pumps.

Advantages of heat pumps

  1. Energy efficiency – Heat pumps can provide more heat energy than they use electricity, which makes them more efficient than traditional heating systems.
  2. Reducing CO₂ emissions – By using renewable energy, heat pumps contribute to reducing carbon dioxide emissions, which supports sustainable development goals.
  3. Versatility – Heat pumps can be used both for heating and cooling rooms, which makes them a universal solution for many facilities.

However, despite these advantages, heat pumps are not always the best solution for every company. Below we present the main disadvantages of this technology.

1. Low efficiency in combination with radiators

Heat pumps are most effective in combination withunderfloor heating, which operates at low heating water temperatures (30-40°C). Traditional radiators, which require higher water temperatures (60-70°C), reduce the efficiency of heat pumps. In commercial and office buildings that are not equipped for underfloor heating, heat pumps will have to work harder, leading to increased energy consumption and higher costs.

2. Decreased performance at low temperatures

In regions with cold climates such as Poland and Germany,air source heat pumps become less effective at very low temperatures. When the outside temperature drops below freezing, heat pumps must work harder to maintain the appropriate temperature inside the building, leading to higher operating costs. In extreme cases, it may be necessary to use additional heat sources, which increases investment and operating costs.

3. Dependence on electricity

Heat pumps are powered byelectricity, which means that their efficiency is closely related to electricity costs. In Poland and Germany, where electricity prices can be high, rising energy costs may negatively impact the profitability of heat pumps. Compared to other technologies that are not as reliant on electricity, heat pumps may not always be the cheapest solution in the long term.

4. High requirements for building insulation

Heat pumps are only effective if the building is wellinsulated. In older buildings that are not properly insulated, heat pumps may not operate at full capacity. In such a case, it may be necessary to modernize the building, which involves additional costs. Poor building insulation forces heat pumps to work harder, increasing energy consumption and operating costs. 

Axtora Energy recommends the use ofPower Loop ThermoCoat - advanced thermal insulation coatings that significantly improve the energy efficiency of buildings. These coatings not only reduce the need for heating and cooling energy, but can also support the operation of other systems, such as heat pumps, by allowing them to operate under more efficient conditions.

5. High installation costs and space for outdoor units

Heat pumps, especially air pumps, require an appropriate amount of space for the external unit. In densely built-up areas or small plots, this may be a problem. Additionally, installing heat pumps involves high initial costs, which may be a barrier for many companies. Although they can generate savings in the long run, the initial investment cost can be high, especially for smaller businesses.

6. Noise produced by outdoor units

Although modern heat pumps are becoming quieter,outdoor unitsof air pumps can generate noise, especially during intense operation in winter. This may be a problem in office or commercial buildings where silence and acoustic comfort are important.


Summary

Heat pumps, despite their advantages, such as reducing CO₂ emissions and energy efficiency, also have many disadvantages that should be taken into account. Low efficiency in cold climates, dependence on electricity, need for good building insulationandhigh installation costs may mean that they are not always the best solution for every company, especially in Poland and Germany. Therefore, before deciding to implement this technology, it is worth considering alternative systems that may prove more profitable and effective in the long term.
