Heating of the hotel building, for undisturbed relaxation

As winter and the end of the year draw near, we yearn for warmth and relaxation. A wellness hotel is a great way to do this Relaxing in the pools and you wouldn't think how much it costs to heat your room, pools or saunas. Fortunately, the Intelligent Thermal Battery can reduce the energy demand and running costs of the heating system.

The Intelligent Thermal Battery was installed in the heating system of Thermal Park Egerszalok at the end of 2023. The hotel consists of two buildings with rooms and apartments for more than 100 guests, a restaurant, a conference room, 4 swimming pools, saunas and a steam room. The energy used for heating is 118 000 kWh/year.


One HeatTank 25-1 Thermal Battery supports the heating peak in the morning, then be recharged during the day, also supporting the system during the evening peak consumption, and then recharged again in the night as demand decreases. The savings come from reducing peak consumption.


For HeatVentors, the demonstration of energy savings is very important. The evaluation of the Thermal Battery operation is done by stopping the Thermal Battery operation for 1-1 day using the Thermal Battery 's control system, these days serve as reference days. The days without Thermal Battery operation are compared to days with similar weather and similar number of people when the Thermal Battery operating, the difference in consumption is the savings.


The Intelligent Thermal Battery saved more than 20% of natural gas prorated for the total heating period.


In addition to the savings, there are other benefits of the Thermal Battery. The savings in natural gas also led to CO2 emission reductions, which for the hotel is equivalent to the annual CO2 absorption capacity of 1.2 football pitches of forest. In addition, the system can be operated in a better operating point and thus reduce the need for maintenance.
