Visit to the premises by a City official with a view to determining the connection route:

The visit to the premises of the building to be connected allows the City agent to define the connection route in mutual agreement with the customer.


Establishment of a heat contract between the City and the customer:

In the event that the customer agrees to the connection to urban heating, a heat supply contract is entered into between the City and the customer. This contract sets the terms of the supply of heat (Access to equipment, power, prices, payments, count, etc.)

The heat supply contract signed by the College of the Mayor and Aldermen is sent to the customer for agreement and signature.

A copy of the heat supply contract countersigned by the customer must be returned to the City Technical Department.


Making the connection to the urban heating network:

The City is responsible for making the connection to the network from the limits of the building to be connected to the main lines.

  1. During the installation of the main pipes, civil engineering costs are borne by the City.
  2. After completion of the installation of the main pipes, all civil engineering costs are the responsibility of the customer.

For details, please see art. 9.2 “Price for connection” of the heat supply contract.

  1. Installation and connection of the transfer station to the primary and secondary circuits by a licensed installer:

The customer charges an authorised installer of their choice with installing the transfer station and making the primary and secondary connections.

The installer must strictly comply with the technical conditions established by the City for making the connection in order to guarantee the proper functioning of the heat supply.

The City carries out a check to determine if all technical conditions have been met.


Installation completion information:

When the installer has completed the connections as well as the heat supply station, they inform Industrial Services in order to schedule an appointment to perform the installation of the heat meter.


Commissioning of the installation

The commissioning of the heat supply will be carried out by the City in the presence of the installer and a representative of the customer.

The customer will receive monthly, from the date of commissioning, an invoice for the supply of heat.
