FAQ

The connection as well as the power of the connection will remain unchanged. Protective devices and other installations placed downstream of the meter will not be changed either.

With the introduction of the smart meter, the consumer receives more detailed information on their consumption habits, enabling them to save energy by changing their behaviour.

Smart meters make it possible to read energy consumption remotely, meaning that staff do not have to disturb customers in order to read their meter on site.

Thanks to smart meters, electricity and natural gas providers will be able to offer customers increased flexibility for innovative pricing and invoicing based on supply and demand in energy markets. Suppliers will thus be able to offer new tariffs that better correspond to consumption habits and issue an invoice at any time of the year based on actual consumption instead of estimates.

A smart meter makes it possible to read energy consumption remotely, i.e. without having to travel to the consumer’s premises. The provision of near real-time information to the consumer will enable them to monitor and control their consumption and energy costs.

Smart meters are part of the reform of the energy markets aimed at encouraging active consumer participation. The smart meter is the first step towards the implementation of a smart electricity distribution network that uses computer technology to optimise decentralised production, distribution and consumption, especially with regard to electromobility, as well as to better coordinate supply and demand between electricity producers and consumers.

The deployment of smart meters is among the measures planned by the Luxembourg Government to enact the European energy directive into national law.

Smart meters use state-of-the-art technology in order to measure the energy (electricity, natural gas, urban heat) or water consumption of each dwelling at regular intervals. The meter records the values and transmits this data via the existing electricity network to a central system, which collects the data from the meters for the whole country and transmits it to the network operator.

The central data collection and management system is managed and operated by the Luxmetering economic interest group, which was created in 2012 by the country's seven electricity and gas network operators: Creos Luxembourg, City of Ettelbruck, City of Diekirch, Electris, City of Dudelange, Sudstroum and Sudgaz.

It should be noted that the network operator builds and operates the electricity or natural gas networks, and that the supplier buys and resells energy and associated services.

The installation of an electricity meter and a heat meter is mandatory in order to qualify for public subsidies. The electricity meter must measure the total electricity consumption of the heat pump (including additional consumers such as the circulation pump and radiators). The heat meter must indicate the amount of heat produced.

This data can be used to determine whether the installation is operating efficiently and, in the event of faults, to call in a specialist quickly.

If the heat pump control system is capable of displaying the data, external installation of components is not necessary.

Yes, geothermal probes also allow you to use a heat pump to cool a building. It is even advisable, as the heat extracted from the house can be used to regenerate the ground.

In this context, a distinction must be drawn between active and passive cooling. In an active system, the heat pump acts as a cooling unit during the summer by actively reversing the circulation within the pump. In a passive system, on the other hand, the heat exchanger is used to evacuate the heat from the dwelling to the probe circuit. Passive cooling is recommended due to the high electricity consumption of an active system.

It is recommended that the drilling work only be performed by a company with DVGW W 120 certification (ADEME-BRGM-EDF quality commitment approach) or equivalent. If the work is not carried out by a competent company, drilling and probe installation work can lead to serious complications, both during the drilling work itself and during subsequent operation. It is also essential to have a sound knowledge of Luxembourg geology.

Find out about this from the drilling company you have chosen.

No. Boreholes drilled for surface geothermal energy cannot under any circumstances trigger an earthquake. Nor has a geothermal probe ever been observed to have been damaged by an earthquake.

Under the new rules for the installation of geothermal probes, damage can be practically excluded if the rules are carefully observed.
