Heating systems in Luxembourg: Always at the forefront of technology

HSL-Technik is your dependable partner for heating systems, whether installation, maintenance or repair.

Cost-effective heating with modern oil heating systems

Condensing technology enables environmentally friendly operation of oil heating systems.

Many homes have obsolete oil heating systems that are neither cost-effective nor environmentally friendly to operate. HSL-Technik replaces old boilers with modern and efficient condensing boilers. These use all the energy in the fuel oil to provide heat throughout the house, whereas the older heating system allows some of the energy to escape out the chimney in the form of hot smoke.
If you already have an oil heating system, switching to a modern oil heating system is certainly the cheapest solution.

The benefits include:

  • You keep your oil tank.
  • It is not necessary to install a gas connection.
  • It is also unnecessary to buy a gas tank.
  • Installation of the new oil heating system is a simple process.
  • Requires only a small investment.

Gas heating provides clean heat

HSL-Technik installs a heating system that consumes gas in a very cost-effective manner.

We ensure that your budget is respected as well as the environment. Modern gas heating systems from HSL-Technik work with low-temperature or condensing boilers. This means that there is no heat loss from the heating circuit above 60 ° Celsius. Condensing technology even uses heat from the waste gases in conventional heating systems. As a result, you save a lot of energy and money with the new heating system.

Gas heating is also environmentally advantageous, as it does not emit fine dust and can work at least in part with biogas.

The benefits include:

  • The gas has a clean combustion process.
  • It is not necessary to install an oil tank, which contaminates groundwater.
  • You have the option of burning gas produced in an environmentally-friendly manner, rather than natural gas.

District heating: Heating with waste heat from industrial installations

HSL-Technik connects you to existing district heating networks so that you can heat in an environmentally-sound manner.

District heating is sent to your home by special electrical networks. It comes from power plants, waste treatment plants or industrial processes. Suffice to say, wasting heat is a nuisance. Instead of being expensively dissipated by cooling, the heat produced is distributed by heat circuits to places where there is an urgent need of heat for heating and hot water supply.

HSL-Technik connects your house to the network, adapts existing heating systems to emerging needs or installs a distribution system with radiators or underfloor heating throughout the house.

The benefits include:

  • You use heat that is already available.
  • No combustion takes place in the house.

Eco-friendly and cost-effective heating with heat pumps

Smart heating using natural heat from groundwater, brine or outside air.

Heat pumps do not heat with electricity or gas, but with the energy available in groundwater, soil or outside air. They extract heat from the environment and feed it into the home’s heating system. It works on the same principle as a refrigerator. The system is suitable for producing hot water and for operating heating equipment.

The benefits include:

  • Heat pumps provide about 2 to 3 times the amount of thermal energy that is used in electrical energy for their operation.
  • Consumption costs are low compared to other heating systems.
  • They save resources because they require little energy.
  • With electric heat pumps, there is no combustion in the house.

Heating with wood: A renewable resource

Modern wood-burning systems are environmentally friendly and offer a high level of comfort.

Heating with wood is almost CO2 neutral, as a tree converts roughly the same amount of carbon dioxide into oxygen that is released when burned. Maintenance is a bit more complicated than with gas heating systems, but pellet heating systems offer almost the same ease of use as heating systems that run on fossil fuels. They ignite automatically and regulate combustion according to the heat requirement. Since high-efficiency filters remove fine dust from flue gases, operating a wood heating system is not only cost-effective, but also environmentally friendly.

The benefits include:

  • Does not contribute to global warming because a wood heating system is CO2 neutral.
  • You heat with a renewable resource.
  • With wood heating, you conserve precious fossil fuels.

Heating without radiators thanks to underfloor and wall heating

Heating panels instead of radiators give you complete freedom in the design of your home.

The popular underfloor heating systems as well as the lesser-known wall heating systems are types of radiant heating systems. They use the surfaces of the existing interior material to heat rooms. Due to large surfaces compared to radiators, only low temperatures are required in the heating circuit. Therefore, underfloor and wall heating systems are ideal for all low temperature heating systems such as heat pumps or solar heating systems. We install the heaters during the construction phase or, in the case of major renovations, in the screed or before plastering the walls. Subsequent installation is usually done with the help of dry underfloor heating systems, which are laid on a screed already in place.

The benefits include:

  • More freedom in terms of the layout of the room because there are no radiators occupying space.
  • Minimal air flow.
  • The whole room is heated evenly.

We offer regular and comprehensive heating system inspections

Preventive maintenance helps avoid heating failures in winter and reduces heating costs.

As part of the heating inspection, we check your heating system configuration so that you can heat all areas optimally and efficiently. Sometimes even slight deviations or very minor damage are enough to prevent your heating system form working as efficiently as it should.

It is also strongly recommended to have your heating inspected before winter, so that it does not stop working when you urgently need heat. There are very few malfunctions that occur without warning; they usually develop gradually. Therefore, we check all components when inspecting the heating system and replace those that no longer meet standards.

The benefits include:

  • The heating system’s operation is regularly optimized.
  • Operation safety is significantly increased.
