Hinged gas boiler: circuit, device, installation, connection, reviews

The hinged gas boiler today is quite common. However, before acquiring it, it is important to familiarize yourself with the device, consider the circuit and learn more about the technology of installing such equipment.

Equipment arrangement

On sale you can find wall-mounted boilers, which are quite compact devices for heating. In the case there are heating elements, and among other components it is possible to allocate a gas burner, a heat exchanger, a pump, an expansion tank, and also automatics. The hinged gas boiler operates by means of a burner, which pumps gas into the combustion chamber. By means of atomizers the distribution of gas in the chamber is provided 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 a more impressive thermal conductivity, among other things, such options demonstrate a more impressive coefficient of efficiency. As for steel elements of the type described, they are resistant to corrosive processes and are sufficiently strong.

The presence of additional elements

Condensing boilers can have one or two heat exchangers. The hinged gas boiler, depending on the capacity, can have up to two circulation pumps. Boiler automation may or may not depend on energy. The latter variant reacts to variations in the pressure of the coolant as a result of cooling or overheating. In the turbocharged models there are fans. Correct operation of the equipment is provided by pressure gauges, gas valves, thermometers, and also air vent. In the event of a power outage, the security system takes effect. It stops the operation of the boiler in the absence of power and closes the valve with the gas supply. After the power is restored, the equipment must be restarted manually.

What else do I need to know about the device?

If you choose a hinged gas boiler, you can prefer a model that has a system to protect against possible freezing. When the equipment is operating in an energy-saving mode, the temperature of the heat carrier is monitored for a long time by the sensors. If the indicator goes down to 6 degrees, the boiler switches on and the coolant temperature rises. After that, the equipment goes back to sleep mode. If there is a desire to purchase a design that will last a long time, then it is worth choosing variations that are equipped with a self-diagnosis system. It allows you to determine up to 90 percent of all kinds of malfunctions. The electronic scoreboard displays information about the nature of the failure.

Some installation rules

After you become aware of the device of the hinged gas boiler, you can think about its purchase and installation rules. The heating system must necessarily be pressed, and it is necessary to provide 1.8 atmospheres. It is also important to deaerate the heating system. All connections must be analyzed for leaks. It is necessary to mount a voltage regulator for the equipment and an uninterruptible power supply. The last requirement is not mandatory. In the heating water, in no case can not add antifreeze. This can damage the gasket and cause a leak in the heating system.

Requirements for premises

Before installing the hinged gas boiler, you must necessarily be prepared room. If it is a private one-family house, the boiler room can be equipped on any floor. It can be, for example, a socle, a cellar, a roof or an attic. The restriction applies to premises of a residential type, a bathroom, and a bathroom, in which the boiler is strictly forbidden.

In order to determine the volume of the boiler house, it is necessary to take into account the thermal capacity of the equipment, the same applies to the capacitive, as well as flow-through heaters. It is necessary to take into account the exception, which is the use of a boiler with a closed combustion chamber. At the same time, the boiler room volume is not standardized. As for the window, its presence is optional. A hinged gas boiler, which is often reviewed positively, should be installed by technology. Thus, for inflow and supply of air, it is necessary to ensure the inflow of a certain volume.

About power

If you want to install a boiler whose capacity is 23.3 kilowatts, then it should burn 2.5 cubic meters of gas for an hour. For the complete combustion of this volume, 30 cubic meters of air are needed for an hour. Provided that not enough air is supplied, the gas will not burn completely. In the end, harmful substances are formed that adversely affect human health. Air masses should come not only from outside, but also from other premises of the house. This is provided by the clearance method, which is located between the floor and the door. Replace this gap with a hole with a grate, which is located in the door.

Features of preparation before installation works

Connection of the hinged gas boiler can be made only after it is possible to make all the preparatory work, as the consumers claim in their reviews. This stage is necessary to ensure that the premises meet all the requirements. Among them, one can distinguish the area of the boiler house, which should not be less than 4 square meters. Ceilings should not be less than 2.5 meters. It is important to install a door whose width is equivalent to 80 cm. The equipment should be illuminated in a natural way, which is provided by the window opening. On 10 centimeters of square premises should be 0,3 m ^{2 of an} aperture of a window. Installation of the hinged gas boiler is carried out only in a well ventilated room. The area of the air intake opening should be 8 cm ² per 1 kW of equipment.

Pipes of the gas pipeline are made exclusively of metal. Flexible sleeves can only be used to connect consumers. The section of the chimney must correspond to the performance of the structure. If this parameter is 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 admit the moment at which the sectional area of the chimney is less than the corresponding value of the opening for connecting the chimney, warns the responses.

Wall boiler installation

After you have decided which hinged gas boiler is best, it is worthwhile to do further work on the preparation of the room. Only then you can make the installation. The equipment is installed on the wall in the event that the power requirements are not very high, as the home masters emphasize in their responses. This approach is also relevant with a small area. Most often this equipment is used for heating water and heating multi-storey buildings. Boilers are not so demanding of free space, which is why they can be installed above appliances that stand on the floor. If necessary, the boilers can be mounted in a cascade. This is convenient if there is a need for considerable power. Install the boiler is necessary, retreating 20 cm from other gas appliances. Among other things, the same distance should be maintained before 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 gap between the walls. Do not install near the window. The power supply must be as close as possible.

Features of work

As customers say in the reviews, even if you use the best hinged gas boilers, you still have to take into account all the rules of installation work. Before installation, it is necessary to flush the equipment and system pipes with water. This will eliminate foreign elements that could get inside the unit at the factory. Planks for fastening should be nailed in 0,8-1,6 meters from the floor. It is important to check the wall for strength and evenness. It should be able to withstand the weight of the boiler and associated equipment. 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 strengthened with a deviation from the wall of 4.5 cm.

Connecting equipment

The diagram of the hinged gas boiler will allow you to familiarize yourself with the equipment arrangement. Before connecting the structure to the water pipes, it is necessary to remove the plugs that are installed on the nozzles. To prevent clogging of the heat exchanger, a strainer must be installed at the water inlet. Ball valves are installed on both sides, which facilitates not only repair, but also maintenance. The next step checks the consistency of the installation. Skewing can cause unpleasant consequences. The connection is made exclusively by a metal pipe. In this case, you must use a rigid connection or special drive. The use of a paronit cushion is mandatory.

It should be noted that the connection of the described equipment is performed only by authorized persons. Such manipulations are carried out after checking all norms and requirements.

The device of the chimney

Materials for the chimney are selected depending on the type of equipment and the fuel to be burnt. As for the gas boiler, the pipes for it must have a cylindrical shape. They should be based on metal, preferably stainless steel. Such structures are the most reliable, safe and durable. The chimney should be brought out above the ridge. It is necessary to equip the hatch, designed for cleaning the chimney. When installing the pipe, it should be noted that the structure should not have more than 3 turns and bends. The pipe that will connect the equipment and the chimney should be as short as possible. Its length should not exceed 25 cm.
