Memories being created while enjoying holidays are something every provider should consider when traying to do the best for their guests. How they feel, how and what the tourism workers do for them – that’s what counts. Heating, cooling and domestic hot water are unavoidable costs to ensure the complete comfort of each and every guest.

n addition to all these costs, tourist accommodation providers have to take care of the appropriate investments, which usually run out of money. Savings are required on basic and inevitable maintenance services. High operating and maintenance costs have an impact on competitiveness and the associated lower growth in other investments for ensuring higher standards. Finding solutions to replace the increasingly expensive and environmentally friendly fossil fuels with newer and environmentally friendly heating sources has led Hotel A into more economically investing of providing comfort for its guests.


Our heat pump has successfully helped reduce costs and increase the efficiency of Hotel A in Žalec. Heating, cooling and supplying hot water for 48 rooms, a restaurant, sauna and fitness room. It is a prestigious hotel with a total net usable area of ​​2,300 m2 and a large number of guests with different lifestyles. This means that a lot of effort has to be put into meeting the wide range of guest needs and activities on a daily basis throughout the year.

The most efficient solutions

At Kronoterm we have developed system solutions to reduce the costs of heating, cooling, swimming pool water heating, hot water preparation, reducing the number of different systems for all services and thus maintaining them. Of course, we have not forgotten about the protection of the environment and the nature. We managed to replace expensive and harmful fuels with our solutions.

During the designing phase of the solution, we had some concerns about whether gas could be avoided, especially for the preparation of hot water and the fulfillment of sanitary requirements. Despite the higher initial input, the investor opted for the proposed solution with special ground-water heat pumps WPG, for which we used 16 geosonds (2xWPG-80 and 2x WPG-110). System of Kronoterm heat pumps uses the temperature of superheated steam to heat the hot water. In this way, it is possible to heat or cool the building and heat the hot water at higher temperatures than 70 °C without reducing the efficiency of the heat pump. One of the important advantages is the preparation of hot water with temperatures higher than 60 °C. This can also be used to protect your guests from the appearance of legionella.

Hand in hand with renewable natural resources

Despite initial concerns, Hotel A managed to completely abandone fossil fuels, which are detrimental to the health of your guests and the surrounding area. From 50 to 80 % of the required heat is now available with our Adapt heat pumps for free from renewable sources (system earth-water).


High savings of Hotel A

After the first operating season with new heat pump, the costs of heating, cooling and domestic hot water preparation are approximately uniform and on average lower than 800 € per month. The investment for which they have decided in Žalec has three times less operating costs, which means that the higher investment will be repaid in less than seven years. In addition to the great savings, the chosen system also provides maximum guest comfort, meets all sanitary regulations and lives in harmony with nature, reducing global warming by more than two and a half times, compared to existing technology.


Heat pumps are the most cost-effective and environmentally friendly heating source in the long run. A heat pump obtains 50 to even 80 percent of all the required heating energy for free from the surroundings, with the remaining part being electrical energy.

Additionally, such heating significantly contributes to reducing CO2 emissions, ensuring a cleaner environment for us and our children.

Apart from utilizing a renewable energy source and long-term cost benefits, the advantages of heating with heat pumps include minimal space requirements and the possibility of obtaining government subsidies. With a heat pump, there is no need for fuel delivery, storage space, chimneys, chimney sweeping services, and maintenance is simple and inexpensive.

In addition to all these advantages, it’s essential to mention remote control of the heat pump and the possibility of remote service diagnostics. Imagine returning from vacation with your family and ensuring, through your phone, that you come back to a warm home with enough hot water for the whole family. Many potential malfunctions can also be resolved remotely without the need for a service technician. A remarkable solution like this is offered, for example, by the company KRONOTERM and their HOME.CLOUD.


Choosing the right pump depends on the heating regime. The surrounding air as a heat source is always available. Still, for even greater efficiency, we need to check if groundwater is available. If not, we can use a geosonde or a ground collector. The heat pump achieves the best efficiency in a low-temperature heating system. When installing, we need to ensure space for the installation of the outdoor unit, especially for an air-to-water heat pump.


When choosing, consider which heat source is most economical to exploit. Follow the rule to choose the one available with the highest average temperature during the heating season. This is primarily groundwater, which has an average temperature of around +10 °C. It must be of adequate quality and available in sufficient quantities, at least 0.2 m3/h for each kW of the heat pump’s heating power.

The next option is utilizing accumulated heat from the ground, either in the form of installing a horizontal collector or a geosonde. In the first case, we need sufficient free ground surface, and in the second, access for a drilling machine must be possible.

If these options are not available, then the best choices are the heat from the surrounding air or an air-to-water heat pump. Air is, of course, available everywhere, but it has the lowest average temperature among the mentioned heat sources (except on the coast), making this source somewhat less efficient.

After determining the availability of heat sources and having multiple options, compare investments and heating costs for each heat source. The return on investment calculation indicates the right direction for choosing a heat pump. The investment in a heat pump pays off in five to seven years, after which only the cost of consumed electricity remains



When choosing a provider, choose a European brand. Even better, choose a Slovenian one. Buying a heat pump from an importer or intermediary can be quite risky. The company may cease its activities, leaving you without support and sometimes even without authorized service, meaning without a warranty. Check the seller and verify whether the company provides complete service and advice and will be available in all possible situations, so that you do not stay without heating in critical moments.

If you want to heat and cool your business or industrial facility in an environmentally friendly and economically viable way, KRONOTERM heat pumps are the right choice for you. Contact us for more information.
