Nursery No. 3 in Burgas is the first in the country to use geothermal energy for heating, cooling and domestic hot water supply.
By means of 22 boreholes, each of which is 100 meters deep, the heat pump installation uses the underground temperature of 5 to 23 degrees without drawing water from the sources.
Two units are supplied with energy – each with a capacity of 85.8 kW for heating and with a capacity of 66 kW for cooling the building.
The temperature in the rooms is maintained within optimal limits depending on the season through 62 fan convectors.
The system, powered by geothermal energy, was officially presented to journalists at a final project press conference. The ceremony was attended by the mayor Dimitar Nikolov, the deputy mayor and project manager Yordanka Ananieva and the director of Nursery No. 3 Pepa Nikolova.
Dimitar Nikolov explained that with the new acquisition, energy costs in the daycare facility are reduced five times, while on the other hand, the comfort for the staff and children in the nursery is improved.
“After seeing all the parameters in terms of savings and the quality of cooling and heating, this gave us additional motivation in the Municipality’s program in the next two years for all nurseries and kindergartens to have similar installations. We have turned to them because they work without rest even in the summer, namely in this season we have problems with cooling. On the other hand, in addition to heating and cooling, we get hot water 12 months a year. At the same time, we save harmful emissions from burning oil and pellets. The saved resource will give us the opportunity to invest in these new technologies,” Nikolov said.
The Municipality of Burgas will use all possible programs to provide financing for the construction of such installations.
If the funds allocated by them are not sufficient, the administration will provide them from its own budget, added Mayor Nikolov.
Plans have already been drawn up for all nurseries and kindergartens to have such modern installations built in them. Technical parameters are currently being calculated in relation to the volumes and spaces that will be cooled and heated. It is a plus that all children’s institutions in Burgas have enough space in their courtyards to carry out the necessary drilling.
The heat pump installation in Nursery No. 3 was built under project No. BGENERGY-1.002-0004-C03 “Implementation of RES through the construction of a geothermal heat pump installation and reconstruction of the heating installation in Nursery No. 3, Burgas”, financed under the “Renewable” program energy, energy efficiency and energy security’ from the Financial Mechanism of the European Economic Area 2014-2021.
