Who can connect and who can offer the service?
Owners and persons to whom material right to construction is established or right to use a property can connect to the heat supply network. The heat supply service is provided by the respective heat transmission company, while the operational management of the heat supply system is performed by a heat transmission network operator, which is a specialized unit of the heat transmission company.
