Hot water and lower bills
Air pollution is a problem of many cities in the world. The same applies to Warsaw – old heat distribution centres, installed in old blocks and houses, are not only ineffective (they cause large energy losses) but make it impossible to transmit hot water from the city network. This affects all local inhabitants in an adverse way. The administrator and owner of the distribution centres (Dalkia), within the framework of the project implemented with support from the Swiss Fund, carries out gradual replacement of old distribution centres with new ones and liquidation of additional water heating boilers.
The group distribution centres are a remnant of old boiler rooms. When in the 70s and 80s, individual central heating boilers were liquidated and individual buildings were connected to the heating system, the infrastructure, which had been left back then, was used. Unfortunately, it does not have good parameters (large losses are recorded while transmitting heat), and also often makes it impossible to transmit hot water. Many distribution centres require urgent replacement due to their technical condition. Thanks to Swiss support, Dalkia (as the owner of the distribution centres) replaces the selected devices. New, individual distribution centres will allow the inhabitants to save on bills, as well as to eliminate gas heaters emitting a lot of pollution during operation. The solutions introduced will also allow their users to regulate the heating temperature and will provide housing communities and cooperatives with a possibility of insulating the building, to save on heating costs even more.
