Inspection of gas installations

Boilers are used in almost all commercial buildings and are widely used in residential and private buildings. From coal-fired boilers, there has been a gradual transition to fuel oil and then to mains gas, which is much cheaper and less dangerous than the others. Boilers work by irradiation when the combustion of the gas or other element heats the metal walls of the boiler to very high temperatures that are transferred to the water forming steam. These boiler systems are usually automatic with individual thermostat control in each room or space, even if the combustion chamber and the boiler itself are in an insulated enclosure.

Although the boiler system is one of the simplest systems, it must almost necessarily be installed at the time of construction. In addition, boilers require a great deal of maintenance, although as they are an economical system, the installation and maintenance amortization is rapid. Heat tends to rise, which is why boilers are usually placed in subfloors. When the air is heated, humidified by a device with water inside the boiler itself, the air rises to the rooms and passes through the louvers that open or close to regulate the temperature of each room.

Gas inspection certificate

Gas-tight boilers are equipment that provide heating and hot water by means of a technology that provides great safety. We tell you all about sealed boilers and compare them with other types of boilers.

A sealed boiler is an equipment that allows to have heating and hot water instantly and whose particularity is that it has a hermetically sealed chamber where combustion takes place. This technology makes it much safer than its predecessors, since the flame is never in contact with the air in the room, so it can not adulterate the air.

The flue pipe of the boiler is not just a tube through which the smoke comes out, but consists of two concentric tubes, i.e. a tube inside another tube. The smoke is expelled through the inner tube and the oxygen necessary for combustion is collected through the outer tube by means of a fan that forces the air to enter.

The appearance of the sealed boiler was a technological revolution, since it solved at a stroke the great problem of the atmospheric boiler. And, as its name suggests, the atmospheric boiler took the air from the atmosphere of the room for combustion and, therefore, we could see the flame.

Which heating boiler is better

The revision of the boiler aims to ensure the correct operation of the device, its efficiency and the absence of risk for all those people who live in the house or building in which the boiler is installed.

It is important to clarify that we should not confuse the boiler inspection with the mandatory periodic gas inspection. As stated in the Royal Decree 238/2013 of April 5, both have a different periodicity and objective and in the second one the complete installation is inspected including meter, pipes and keys, gaskets and rubbers and ventilation of the dwelling.

The first thing to take into account is that it can be a reason for fines, for not keeping the inspections up to date, and also in case of any incident or accident the insurance is not obliged to bear the costs of the problems caused.
