For heating and constant water supply high temperature A variety of efficient equipment is used. Special attention deserve quality ones, which are presented in a large assortment.

The operating instructions for hot water boilers are quite simple and understandable. The consumer is offered the most different models such equipment, therefore it is possible to select exactly the one that will be most effective according to its parameters in each specific case of the heating system.

The main reason for the popularity of boilers of this type is that their service life is longer than that of conventional simple boilers; moreover, the quality of the supplied hot water much better.

Nowadays, water heating devices are produced that are able to operate on such types of fuel as:

In addition, there are high-quality ones that are able to operate on different fuels; they are characterized by the ability to switch modes.

Operating rules for hot water boilers

Wall-mounted and floor-mounted boilers are used to install heating systems.

The latter are able to operate on any type of fuel. Before operating the device, it is necessary to perform it strictly on the floor surface; it is better if a separate room is allocated for this. The operating instructions for hot water boilers must also be followed.

The equipment is equipped with all the required automation, so the operation process is simple. When operating the device, human presence may be required only to make certain temperature changes, as well as if it is necessary to turn off the equipment in the event of an emergency.

Modern wall-mounted devices are mounted on the wall surface. Such equipment has compact dimensions, is easy to use, and does not require a separate room.

All without exception hot water boilers, purchased from a trusted manufacturer, have a fairly long service life, are relatively simple and lightweight, are economical and can be installed very quickly.

Features of use and service life of a hot water boiler

Gas hot water boilers are very popular. They are characterized for a long time operation, high quality work, and relatively simple maintenance. Wall mounted gas boilers can be made in several modifications.

As a rule, for heating an ordinary residential building, special double-circuit modifications are used, which are intended not only for efficient heating, as well as for supplying hot water.

Single-circuit devices are used a little less frequently. They are used exclusively for space heating. Directly depending on how air is supplied to a given heating device, boilers equipped with special closed chambers can be used. It is important to note that during the installation of this device, you will need to install an air duct.

The service life of a hot water boiler, if all requirements are met, is quite long, on average from 10 to 20 years, depending on the type of equipment. The duration of operation before the first cleaning from internal contamination is at least 3000 hours. Service life between major repairs– at least 3 years.

Full service life of boilers (with an average boiler operating time per year - 3000 hours): with a productivity of no more than 4.65 MW - 10 years; with a capacity of up to 35 MW – 15 years; with a capacity of more than 35 MW – 20 years.

Application of heating boilers with an open chamber

The process of operating boilers that have an open combustion chamber in mandatory involves the use of air that is in the room where the equipment is installed.

Similar wall-mounted water heating units have some design features, which determines the peculiarities of their operation. This is the presence of such elements as:

The combustion chamber.
Expansion tank.
Pump.
A system that is designed to remove the main combustion products.
Automation and security system.

Operating manual for hot water boilers

Immediately after implementation installation work, the water heating boiler is connected to the network, as well as to the water supply system. The device is connected to the network, and the process of heating water to a preset temperature begins.

As soon as the set rate is reached, the device automatically turns off. All this greatly simplifies the operation process; there is no need to constantly monitor the temperature conditions.

To ensure high-quality thermal protection, this device is equipped with a special relay.

During the installation process, you must strictly follow the instructions provided by the manufacturer.

In essence, this is a manual for the operation of hot water boilers. As a rule, all the main elements are supplied with the device, but it is recommended to first check the presence of all components.

Additionally, you may need some parts and arrangement of related elements of the heating system:

Fittings for quality connections.
Water pipes.
Ventilation and exhaust system.
Electrical accessories.
Set of tools.

The basic principles of operation of this equipment are that when the fuel used is burned in a special chamber, it produces required quantity heat. After this, the water entering the system is heated. There are several varieties of such boilers, as a rule, these are wall-mounted and floor-mounted structures, as well as gas, electric and condenser. The choice of a specific device is made taking into account the features and specifics of the structure.

The boiler operating instructions are a set of rules and requirements that are attached in printed form to each model. Despite the variety of gas heating equipment, the principles of use and safety are the same for all models.

Operating principle of the boiler

Gas heaters can vary in design and technical parameters, but the principle of creating heat in the house is the same - heating the coolant (water/antifreeze) with combustion gas (natural/liquefied). Supplying gaseous fuel to a residential area is not the easiest or safest thing to do, but consumers are attracted to gas, its comparative cheapness and versatility.

Blue fuel can be used not only for heating, but also for heating domestic water using columns or dual-circuit heater models. Modern equipment is equipped with effective safety systems that prevent all possible emergency situations. Nevertheless, there are operating rules that must be followed and are a guarantee of safe operation.

Precautionary measures

Despite the manufacturers' commitment to safety gas apparatus, they can still become a source of danger. The Ministry of Emergency Situations regularly reminds owners of any gas-powered equipment about the following precautions:

1. You need to buy gas-powered appliances from organizations that have the appropriate sales license.
2. Installation should only be carried out by specialists from the relevant services.
3. The kit should include an instruction manual.
4. It is prohibited to change the design of the device in any way.
5. A technical inspection must be carried out annually.
6. It is prohibited to reduce ventilation openings in windows and walls.
7. If there are sealed windows, it is necessary to organize air flow.
8. Materials that can quickly ignite should not be stored in the boiler room.
9. It is prohibited to increase the coolant temperature above 90°C.

Posting rules

1. The area of ​​the room in which the heater is installed is at least 7.5 m².
2. Ceilings - from 2.2 m.
3. There must be a window providing access to air from the street.
4. The door should open in the direction of movement of the person leaving the room.
5. It is prohibited to install switches in the boiler room. If they are already installed, you will have to take them outside the premises.
6. Need to equip supply and exhaust ventilation. For every m³ of fuel consumed - 15 m² of air.
7. The distance from the heater to elements capable of burning is 25 cm or more. To non-combustible elements - 5 cm. From the chimney to combustible parts - 40 cm, to non-combustible parts - 15 cm.
8. The device is mounted on a perfectly flat plane, without slopes.

Chimney requirements

1. Chimney material - steel. It is recommended to use stainless steel.
2. Cleaning hatches and condensate drainage are required. There should be a pocket at the bottom of the chimney where deposits accumulate.
3. The chimney is equipped with external thermal insulation, which is protected from moisture (condensation, precipitation).
4. The height of the chimney is from 5 m and at least 2 cm above the outlet pipe.
5. The smoke exhaust is installed on the receiving plate of the vapor trap.
6. The expansion tank is installed in the very high point systems.
7. A safety group and a thermometer are installed on the supply pipeline.
8. It is not advisable to place the device in openings, niches and other hard-to-reach places.

How to use

IN modern models heaters, human participation is reduced to a minimum. Before the device is started, it is connected to:

• gas pipeline - gas service workers;
• heating pipes;
• water supply - representatives of organizations servicing heating systems.

The first start-up is also carried out by service workers. If the instructions are violated during connection and maintenance, the warranty will be void. The equipment must be used only for the purposes intended by the manufacturer.

During installation, maintenance and repair, original spare parts must be used. If a breakdown or incorrect operation is detected, the user must immediately turn off the gas valve and call the service or gas service. Produce renovation work independently is strictly prohibited.

When performing any work on or near an air duct or chimney, turning off the gas is mandatory. Having completed the work, they check the functionality of the chimney and air duct and only then proceed to start up the device.

How to turn off the boiler correctly

If the device will not be used for a long time, perform the following actions:

1. Close the gas valve.
2. If the equipment is volatile, you need to disconnect the automation and water pump from the power supply.
3. Turn off the water supply and heating valves.
4. If the temperature is expected to drop below zero, you will have to drain the water.
5. Call a specialist to completely turn off the equipment.

The heater is also turned off for cleaning. Clean it with a damp cloth and soft detergent and soap. The use of aggressive substances is prohibited.

Safety system

Gas-powered appliances require serious monitoring. It is provided either by a person or an automation system. The latter is capable of providing multi-stage protection that prevents dangerous situations and increases equipment safety. The main task of the protection system is to turn off the device in time by stopping the fuel supply.

Let's look at the stages of protection using the example of the floor-standing boiler "Wolf KSO". These modern devices have multi-stage protection. One of the stages is an ionization sensor that controls the flame. If the fire goes out, a signal will be sent to the control unit, it will shut off the fuel supply and prevent an accident.

The combustion chamber has a temperature sensor that monitors the heating of the coolant and prevents the firebox from quickly burning out. “Wolves” are equipped with a KTD system - chimney draft control. It prevents the accumulation of carbon monoxide. If there is no draft, combustion products begin to accumulate in the chimney, and the thermostat heats up. When the temperature limit is reached, the thermostat contacts open and the flow of fuel stops.

Automatic protection

Modern heater models are equipped with electronic control and measuring instruments that generate signals for the control unit. Automation, receiving signals from sensors, coordinates the work of all nodes. Elements that prevent various kinds malfunctions and problems are safety valves, expansion tanks, air valves, smoke detectors and other devices.

What to do if problems occur

Let's look at breakdown situations using the example of Italian boilers. Italian wall and floor heaters are an example of quality and efficiency. But even with proper use, malfunctions may arise that require prompt correction.

The following problems may appear in Baksi models:

• the burner does not light;
• during operation, popping noises are heard in the firebox;
• the boiler overheated;
• the device is very noisy;
• The sensor has failed.

The probable causes of breakdowns are associated both with violations of operating rules and with reasons beyond the control of the user:

• moisture has entered the device;
• low quality coolant;
• the pressure in the gas pipeline has decreased;
• voltage drop in the electrical network;
• errors were made during installation.

Violation of at least one rule or norm leads to breakdowns, incorrect operation and unnecessary costs.

Frost protection

One of important rules operation of heating systems - ensuring the minimum permissible coolant temperature. If the system is filled with water, then when low temperatures freezing occurs, pipes and radiators become unusable. In modern models, this problem is solved - the user is relieved of the need to monitor the coolant.

For example, boilers from a South Korean manufacturer provide reliable protection from freezing. Navien is cheaper than its European counterparts, but these boilers have all the necessary protection functions, which greatly simplifies their use.

When the coolant temperature drops below 10°C, the circulation pump starts automatically. If the coolant cools down to 6°C, the burner automatically turns on, warming the coolant to 21°C.

Ignition instructions

Heaters differ in the type of ignition, so when starting different modifications there are some nuances. Before turning on the device, you need to read the ignition instructions to ensure everything is done correctly. Let's look at ignition using the example of the Italian boiler "". Before turning it on, it is important to check the system for leaks. For this purpose, the thermostat is turned on to maximum so that the switching occurs automatically. Ariston ignition process:

• the device is connected to the power supply, and the heating regulator is set to the desired temperature value;
• When the pump is turned on, a slight noise is heard;
• when all air pockets in the pipes are eliminated, the noise will disappear;
• the electric ignition is triggered - the boiler turns on independently.

Self-diagnosis

The process of operating heaters is simplified if they have a self-diagnosis function. Almost all European manufacturers have equipped their products with it.

For example, German “” heaters, displaying error codes on the display, allow the user to quickly understand the cause of the problem and take measures to eliminate it. If code A7 appears on the screen, it is clear that the hot water temperature sensor is faulty.

If A8 is displayed, the connection to the BUS bus is broken. This feature makes it much easier to use gas equipment, makes it easier and more comfortable.

Dangerous situations

The greatest danger is a malfunction associated with the operation of the burners. If the flame goes out, gas may accumulate in the room, which will subsequently cause an explosion. Reasons for the fire going out:

• gas pressure has dropped below the permissible norm;
• no draft in the chimney;
• the supply voltage has disappeared;
• The pilot light went out.

IN emergency situation it is necessary to immediately shut off the fuel supply to the burners - automatically or manually. Modern versions are equipped with automation devices necessary for prompt shutdown of equipment. The operation of such devices is not only convenient, but also safe.

How to prevent gas accumulation indoors

Modern safety standards provide for the installation of gas analyzers in boiler rooms; they are necessary for signaling when gas appears in the room. A special electronic valve reacts to their signals, automatically stopping the flow of fuel to the burners.

What other safety regulations are there?

• Do not disassemble or dismantle gas devices on one's own.
• Handle the power cord carefully.
• Do not place foreign objects on the device.
• Don't stand on the boiler. Do not stand on chairs, tables or other unstable objects to clean the wall-mounted boiler.
• Monitor the coolant and add it to the system on time.
• Be careful - in some modifications the use of antifreeze is prohibited.
• If you smell gas, immediately turn off the gas and open windows and doors. Leave the boiler room and call the gas service.
