Installing a new heat production unit in a company

The heating installation: an important leverage point in the energy transition

To protect against the unpredictability of the energy market and successfully achieve the energy transition, the heat production unit is a major leverage point. As its purpose is to supply heat for comfort and operational needs, the heating system must scale to provide the temperature levels and quantities necessary to keep the business running smoothly at all times. Today, there are heat production systems that are adapted to each temperature level, can be modulated in terms of power and are environmentally friendly.

Definition of the company’s heating requirements

Analysis of the current situation

• Determine the parameters of the current installation, e.g. age, general condition, temperature level, consumption and associated costs, etc.

Needs assessment by a qualified tradesman (heating installer) or by an advisory engineering office:

• Analysis of general heating requirements in accordance with DIN EN 12831.
• Analysis of the power required by heat-consuming appliances
• Analysis and reassessment of the temperature levels required for the various applications.

Identification of the solution and verification of the feasibility of the heating installation project

Definition of the solution

• Based on the needs analysis, define the solution in collaboration with a supplier, a consultancy office or a qualified tradesman (heating installer).
• In addition to the main heat production unit, consider recovering waste heat or combining the unit with solar thermal heating.

Verification of the proposed heating installation regarding operating permits

When adapting existing installations and particularly when setting up new installations, check the nomenclature of classified establishments.

Application for subsidies from electricity and natural gas suppliers

As of 2015, natural gas and electricity suppliers are obliged under the Commitment Mechanism to generate energy savings among their consumers. Since then, energy suppliers have been offering monitoring and advisory services as well as subsidy programmes for consumers to implement energy efficiency measures.

The providers offering this service to companies are as follows:

• Enoprimes Enovos + SUDenergie
• SUDenergie
• Sudstroum

Application for a premium from the nova naturstroum fund

The objective of the nova naturstroum fund is to promote and valorise sustainable development in Luxembourg. The following premiums are available specifically for businesses:

• “heating” premium

It should be noted that the subsidies from suppliers and the premium from the Fonds nova naturstroum can be cumulated with any state subsidies for the same project.

After the heating installation has been carried out

• Inspection of the installation by a representative of the Chambre des Métiers
  • Approval of any new heating installation using diesel, solid fuel or gas by the SCRB Department of the Chambre des Métiers.
• Scheduling of regular maintenance and inspection of the installation.
