Gas Boiler Installations with the Professionals

The gas condensing boileris undoubtedly the most efficient boiler on the current market. Depending on the model you choose, you can achieve energy savings on your heating consumption of up to 20%, compared to a conventional low-temperature gas boiler. Installing a gas condensing boiler in place of your old boiler, on the floor or on a wall, is relatively simple. On the other hand, the installation of a gas condensing boiler is subject to several conditions which concern the heating circuit, the methods of installation or the evacuation of condensates.

Perfect Central Heating Solutions

The central heating circuit is the first condition to be able to install a gas condensing boiler. If your newhigh energy performance gas boiler replaces an existing boiler, it is recommended to carry out a sludge the heating circuit. Sludge removal consists of eliminating the sludge that accumulates in the central heating circuit. It is part of the general maintenance of your heating system, and allows you to reduce your energy consumption. You can find out more here.

The central heating circuit is a classic network of pipes between the boiler and transmitters which distribute the heat. These are hot water radiators, high or low temperature, or aheating floor. The installation of a gas boiler in a home is compatible with all types of radiators.

Network operation is optimal when there are transmitters operating at an average temperature below 65 °. The efficiency increases when the return water temperature is low. If your circuit has radiators that operate with water heated between 75 ° and 90 °, called high temperature, the system is less efficient.

Choose A Professional

Installing a gas boiler in your home involves technical constraints. As your condensing gas boiler produces combustion, it releases fumes. Therefore, the heating engineer will have to install a pipe allowing the extraction of the products resulting from the combustion (burnt gases), as well as the evacuation of the condensates (water vapors with acidic pH or waste water). 

Thus, the evacuation of the burnt gases and of the waste water is generally done by means of one of the three types of installation below:

  • a horizontal suction cup placed on the wall
  • a vertical suction cup placed on the roof
  • a casing directly installed on the flue of your chimney

The boiler duct is usually made of PVC, as it must resist corrosion from acidic water. If the duct is made of cast iron or cement, a filter or a condensate neutralizer must be installed in addition to prevent damage to the pipe. The condensate filter is also recommended if the habitat is on a septic tank, in order to limit soil pollution. 

 

For information, air inlets are not necessary in the room where the gas condensing boiler is installed, unlike the low temperature gas boiler. Indeed, the evacuation of fumes and condensates is sealed, that is to say that the air supply is made directly to the outside through the flue. The boiler, which burns gas, condenses the water vapors contained in the fumes. This, by cooling, makes its water vapor component liquid.

Have a gas boiler installed by a qualified professional

The gas condensing boiler must be installed and put into service in compliance with the gas reference system drawn up by the certification and control bodies. Therefore, the intervention of a professional certified Professional Gas heating engineer is essential. The installation of the gas condensing boiler by a qualified workforce is carried out in several stages: 

  • hydraulic, electrical, gas and water connection
  • fitting of the drain valve and the flue gas discharge pipe
  • Commissioning of the gas condensing boiler.
