The mounted gas boiler is quite common today. However, before purchasing it, it is important to familiarize yourself with the device, consider the diagram and learn more about the technology for installing such equipment.
Equipment Arrangement
On sale you can find wall-mounted boilers, which are quite compact devices for heating. The housing contains heating elements, and among other components, a gas burner, a heat exchanger, a pump, an expansion tank, as well as automation can be distinguished. The hinged gas boiler works due to the burner, which pumps gas into the combustion chamber. With the help of nozzles, the distribution of gas in the chamber is ensured to increase the temperature of the coolant. Modern models have simulated burners that allow you to adjust the intensity of the flame and maintain a certain temperature. The heat exchanger is often made of stainless steel, which is sometimes replaced by copper. The latter variety is characterized by more impressive thermal conductivity, among other things, such options demonstratemore impressive efficiency. As for the steel elements of the described type, they are resistant to corrosion processes and are strong enough.
Availability of additional items
Condensing boilers may have one or two heat exchangers. The hinged gas boiler, depending on the power, can have up to two circulation pumps. Boiler automation may or may not depend on energy. The latter option responds to variations in coolant pressure as a result of cooling or overheating. Turbo models have fans. The correct operation of the equipment is ensured by pressure gauges, gas valves, thermometers, as well as air vents. In the event of a power outage, a security system comes into play. It stops the operation of the boiler in the absence of power and closes the valve with gas supply. After the power supply is restored, the equipment must be restarted manually.
What else do you need to know about the device?
If you choose a hinged gas boiler, you may prefer a model that has a system of protection against possible freezing. When the equipment is operating in energy-saving mode for a long time, the temperature of the coolant is monitored by sensors. If the indicator drops to 6 degrees, then the boiler turns on and the temperature of the coolant rises. After that, the equipment goes back to sleep mode. If you want to purchase a design that willserve for a sufficiently long time, then it is worth choosing variations that are equipped with a self-diagnosis system. It allows you to identify up to 90 percent of all possible faults. The electronic scoreboard displays information about the nature of the breakdown.
Some installation rules
After you have become aware of the installation of a mounted gas boiler, you can think about purchasing it and installing it. The heating system must be pressure tested, while it is necessary to provide 1.8 atmospheres. It is also important to de-air the heating system. All connections must be analyzed for tightness. It is necessary to mount a voltage stabilizer for equipment and an uninterruptible power supply. The last requirement is optional. In no case should antifreeze be added to the heating water. This may damage the gasket and cause leakage in the heating system.
Requirements for the premises
Before you install a hinged gas boiler, you must definitely prepare the room. If we are talking about a private single-family house, the boiler room can be equipped on any floor. This can be, for example, a basement, basement, roof or attic. The restriction applies to residential premises, a bathroom, and a bathroom in which it is strictly forbidden to place a boiler.
In order to determine the volume of the boiler room, the thermal power of the equipment should be taken into account, the same applies to capacitive,as well as flow heaters. An exception must be taken into account, which is the use of a boiler with a closed combustion chamber. At the same time, the volume of the boiler room is not standardized in any way. As for the window, its presence is optional. A hinged gas boiler, reviews of which are quite often positive, should be installed according to technology. Thus, for the removal and supply of air, it is imperative to ensure the inflow of a certain volume.
About power
If you have to install a boiler with a capacity of 23.3 kilowatts, then 2.5 cubic meters of gas should be burned within an hour. For complete combustion of this volume, 30 cubic meters of air are needed for an hour. Under the condition that not quite enough air is supplied, the gas will not burn completely. Ultimately, harmful substances are formed that adversely affect human he alth. Air masses should come not only from the outside, but also from other areas of the house. This is ensured by the method of arranging the gap, which is located between the floor and the door. You can replace this gap with a hole with a grate, which is located in the door.
Features of preparation before installation work
Connecting a hinged gas boiler can only be done after all the preparatory work has been completed, as consumers say in their reviews. This stage is necessary to ensure that the premises meet all requirements. Among them one canallocate the area of \u200b\u200bthe boiler room, which should not be less than 4 square meters. Ceilings should not be lower than 2.5 meters. It is important to install a door whose width is equivalent to 80 cm. The equipment should be lit naturally, which is provided by the window opening. For 10 centimeters of a square room there should be 0.3 m2 of the window opening. Installation of a hinged gas boiler is carried out only in a well-ventilated room. The air inlet area should be 8 cm2 per 1 kilowatt of equipment power.
Gas pipeline pipes are made exclusively of metal. Flexible hoses can only be used to connect consumers. The cross section of the chimney must correspond to the power rating of the structure. If this parameter is equal to 30 kilowatts, then the diameter of the chimney should be 130 millimeters. With a power of 100 kilowatts, the diameter increases to 170 millimeters. It is impossible to allow a moment at which the cross-sectional area of \u200b\u200bthe chimney is less than the corresponding indicator of the hole for connecting the chimney, reviews warn.
Installing a wall-mounted boiler
After you have decided which mounted gas boiler is better, it is worth doing further work to prepare the room. Only then can you carry out the installation. Equipment is installed on the wall if the power requirements are not very high, as home craftsmen emphasize in their reviews. This approach is also relevant for a small area. Most often like thisthe equipment is used for heating water and heating multi-storey buildings. Boilers are not so demanding on free space, which is why they can be installed above appliances that are on the floor. If necessary, the boilers can be mounted in a cascade. This is convenient if there is a need for significant power. It is necessary to install the boiler, stepping back 20 cm from other gas appliances. Among other things, the same distance must be maintained to flammable materials. Depending on the model and power, the distance between the boiler and the wall can vary from 30 to 50 cm. It is undesirable to plan the installation of the boiler in the opening between the walls. It should not be installed near a window. The power supply should be as close as possible.
Features of the work
As buyers note in the reviews, even if you use the best mounted gas boilers, you still have to take into account all the rules of installation work. Before installation, the pipes of the equipment and system must be flushed with water. This will eliminate foreign elements that could get inside the unit at the factory. Mounting strips must be nailed 0.8-1.6 meters from the floor. It is important to check the wall for strength and evenness. It must be able to support the weight of the boiler and related appliances. If the surface is made of combustible material, then a gasket is fixed to it, which does not ignite and does not burn. Its thickness should be 3 millimeters or more. In this case, the boiler is strengthenedwith a 4.5 cm offset from the wall.
Connect equipment
The diagram of a hinged gas boiler will allow you to familiarize yourself with the device of the equipment. Before connecting the structure to the water pipes, remove the plugs that are installed on the nozzles. In order to prevent clogging of the heat exchanger, a strainer should be installed at the water inlet. Ball valves are installed on both sides, which facilitates not only repair, but also maintenance. The next step is to check the evenness of the installation. Distortion can lead to unpleasant consequences. The connection is made exclusively with a metal pipe. In this case, a rigid connection or a special drive should be used. The use of a paronite gasket is mandatory.
It is worth considering that the connection of the described equipment is carried out exclusively by authorized persons. Such manipulations are carried out after checking all the norms and requirements.
Chimney device
Materials for chimney are selected depending on the type of equipment and combustible fuel. As for the gas boiler, the pipes for it must have a cylindrical shape. They should be based on metal, preferably stainless steel. Such designs are the most reliable, safe and durable. The chimney should be taken out above the ridge. Be sure to equip a hatch designed to clean the chimney. When installing the pipe, it should be noted that the structure should not have more than 3 turns and elbows. The pipe that will connect the equipment and the chimney should be as short as possible. Its length is notmust exceed 25 cm.
