Cold Shower: "Sofia District Heating" to Begin Annual Maintenance of Heating Infrastructure in the Capital

“Toplofikatsia Sofia” (Sofia District Heating) will begin the phased implementation of its annual maintenance programme for the main and auxiliary facilities across the city’s heating zones, the company announced on July 4.

The purpose of the maintenance is to carry out mandatory technical inspections, testing, and preventive servicing, as well as to use the opportunity to perform urgent repairs on compromised sections of the heating transmission network. Under normal operating conditions, such work could result in unexpected service interruptions lasting more than 48 hours — something the company aims to avoid through timely planning and execution.
