We are proudly announcing that our company KRONOTERM has recently received a prestigious award in the field of energy efficiency and sustainable development. Switzerland, a country with an exceptionally environmentally conscious society, ranked our DHW heat pump ECO at an enviable first place among all tested DHW heat pumps from European providers based on independent testing.



The recognition awarded by the prestigious Swiss association TCS represents a significant milestone for our company. TCS enjoys high public trust, and they recently highlighted KRONOTERM DHW heat pump ECO as the leading in efficiency among five selected tested models from across Europe in their association magazine.


This recognition is not just an achievement but confirms our commitment to the development of advanced and environmentally friendly technologies. We follow the vision of sustainable development, combining innovative approaches, technological progress, and environmental care. The DHW heat pump ECO is a reflection of these values and efforts, undoubtedly expressing our commitment to creating a more sustainable world.


We invite you to read the details of our success presented in the article below.




TCS Tests DHW Heat Pumps

DHW heat pumps represent an extremely efficient and cost-effective method for domestic hot water preparation. It is an innovative technology that utilizes ambient air for energy-efficient water heating, thereby reducing energy consumption and contributing to lower energy costs and reduced environmental impact. Recent tests of different models have shown that investing in a DHW heat pump is meaningful both for financial savings and for a positive environmental impact.


TCS (Touring Club Switzerland) recently tested five different models of DHW heat pumps to assess their performance and efficiency.


Among the tested models of DHW heat pumps, the DHW heat pump ECO from KRONOTERM stood out for its exceptional efficiency.

When planning and installing DHW heat pumps, it is advisable to seek a professional who can assist in finding the optimal location and proper system sizing. Although the initial investment in a DHW heat pump is slightly higher than with conventional water heaters, the long-term energy bill savings quickly prove to be an excellent investment. With potential savings of over 500 EUR per year, the investment in a DHW heat pump pays off relatively quickly.


In addition to financial savings, using a DHW heat pump is also an environmentally friendly decision. Consuming less energy compared to conventional heating systems significantly contributes to reducing the carbon footprint and relieving electrical grids. This makes it an ideal solution for those aiming for efficient and sustainable domestic hot water heating while contributing to the fight against climate change.


DHW Heat Pump: Savings without Compromising Comfort

Heat pumps represent a key innovation for environmentally friendly energy utilization in buildings and are increasingly important for heating and preparing warm domestic water. DHW heat pumps bring numerous benefits, not only heating water but also significantly reducing electricity consumption. Therefore, using them in homes makes sense both from an environmental and cost perspective.


Preparing hot water is a crucial need for every household, so owners of single-family houses often inquire about the most efficient and environmentally friendly solution. In this context, DHW heat pumps are becoming increasingly popular as they allow for more sustainable and cost-effective preparation of warm domestic water. In the average Swiss household, 50 percent of the electricity bill is attributed to heating hot water. A DHW heat pump reduces this consumption by about two-thirds.


The operation of a DHW heat pump is simple: the device contains a small heat pump that draws air from the surroundings to heat the water, which is then stored in an integrated boiler. At the same time, the released air, from which heat and moisture have been extracted, is cooled and dried and released back into the environment. The high energy efficiency of DHW heat pumps is one of the key advantages, as they produce more thermal energy than needed for their operation. This means significant energy cost savings compared to other heating systems.


Studies have shown that owners of single-family houses who switch to DHW heat pumps reduce hot water preparation costs by 65 to 75 percent. DHW heat pumps are flexible and can be installed in various environments, both in new buildings and when renovating existing ones. During installation, it is important to carefully choose the location of the warm domestic water storage tank to ensure optimal efficiency and performance. An ideal location is the laundry room, where the device can serve a dual function of drying laundry and heating water. The noise produced by the device during operation is comparable to the noise of a refrigerator, so it is better to install it in the basement.


It is important to mention that DHW heat pumps often contain environmentally friendly refrigerants. With proper installation and maintenance, there are no concerns about harmful emissions into the environment. Overall, DHW heat pumps are an excellent choice for owners of single-family houses seeking efficient and sustainable preparation of warm domestic water. They offer high energy efficiency, noticeable cost savings, relief to the electrical grid, and contribute to reducing environmental impacts. When transitioning to a DHW heat pump, careful planning and installation are crucial to achieve optimal results. With proper preparation and expert support, property owners can fully leverage the benefits of DHW heat pumps.

How Were DHW Heat Pumps Tested?

DHW heat pumps were tested in a laboratory at a constant room temperature of 20°C in economic mode. The measurements included the coefficient of performance (COP), maximum single water withdrawal at 40°C, heating time, energy consumption, and standby power consumption. The noise level produced by the devices during operation was also examined. The testing provided objective data on the efficiency and performance of DHW heat pumps, which is crucial when deciding on the most suitable device for each household.
