Boiler column Hephaestus turbo rules of use. Heating systems for country and country houses

Heating private houses using solid fuel does not lose its relevance. It does not require large expenditures on equipment and fuel, allowing you to maintain heat in the house even far from gas mains. The most affordable are classic hot water boilers.

One of the domestic manufacturers supplying heating equipment is the Novosibirsk Metalworking Company. Over 20 years of work, its highly qualified specialists have developed a wide range of solid fuel boilers.

Water heating boilers Hephaestus

NMK products are manufactured using modern equipment from high-quality materials. It includes heating equipment and metal products, in particular, various furnaces and boilers that differ in design, purpose, and cost.

The Siberia series of hot water boilers includes the Hephaestus model range, designed for heating houses up to 300 m2 with an autonomous heating system with natural or forced circulation.

These steel solid fuel units are in no way inferior to their foreign counterparts in performance and quality. In addition, the boilers have an attractive modern design. The spacious firebox allows for both front and top loading.

Water from the return flow enters the pipe at the bottom and circulates in the water jacket and through the pipes, and then exits into the upper pipe. Inside the body there is a firebox in which fuel burns, heating the walls, lid and bottom, from which thermal energy is transferred to the water.

The air flow into the combustion zone is adjusted manually, or you can additionally purchase a draft regulator. The kit includes a heating element that can be used to heat water in the heating system simultaneously with fuel combustion or separately.

Design features make the boilers easy to use and economical. In addition to the water jacket, there are heat exchanger systems at the bottom and at the outlet, in the zone of maximum temperature of heated gases.

Basalt fiber jacket under a layer of sheathing with polymer coating provides maximum thermal insulation, which increases efficiency. Coal, brown coal or firewood can be used as fuel. The burning time is from 6 to 8 hours.

Such an inexpensive solid fuel boiler simplest design with a minimum set of automation has positive reviews and allows you to successfully heat a small, high-quality insulated house. The manufacturer provides a warranty of 36 months, the stated service life is 10 years.

How to choose a boiler for your home

Having decided to buy a solid fuel boiler, you need to decide on the required power of the unit. If it is insufficient, it will not be possible to maintain a comfortable temperature in cold weather. When too high power the heat generation will be excessive, the boiler may overheat and even fail.

For effective use fuel, the heat generated by the boiler must correspond to the heat loss. Heat loss occurs through windows, doors, roofing, walls, floors, and ventilation systems.

Consequently, this indicator depends on the thermal conductivity of the materials from which they are made. Besides, great importance has a temperature outside. The lower it is, the more the room cools down.

For each material there is a certain indicator of heat transfer resistance. The higher it is, the better material retains heat. These indicators can be found in construction reference books. The calculation is made based on weather data.

Select the coldest week of the year in this region and calculate the average temperature. This will allow you to select a boiler power that will provide warmth in the house even at minimum temperatures. Based on the initial data, heat loss is calculated for each surface in the house.

Advice! The required boiler power must be calculated by a competent heating engineer. But you can calculate it approximately knowing that with a ceiling height of 2.7 m per 10 m2 there should be 1 kW.

To use fuel more economically, it is important to ensure high-quality thermal insulation at home. To reduce heat loss, it is necessary to insulate the walls, roof and floor, provide waterproofing, and install high-quality windows.

Installation and connection of the boiler

• Since electrical equipment is used, the boiler must be grounded.
• The coolant in the heating system can be either purified water or antifreeze (not containing ethylene glycol). The water undergoes special treatment to prevent the appearance of scale.
• The floor base must be prepared taking into account the weight of the boiler. To protect floor coverings made of flammable materials, it is necessary to cover an area of ​​the floor within a radius of at least 50 cm around the boiler with a protective steel sheet with an asbestos lining. If the subfloor is not stone, it is recommended to install a quarter-brick brick deck.
• The distances from the walls must be 500 mm, to the ceiling - 1200 mm, from the door side - 1250 mm.
• A safety valve must be installed at the boiler outlet.
• The heating system must provide for complete removal of air, as well as the possibility of completely draining the coolant.
• For the installation of a chimney, thermally insulated pipes made of of stainless steel. A brick chimney can be used.
• On systems with forced circulation the pump is placed in parallel in case of power failure.
• An expansion tank is located at the top point of the system (for open system) or a safety group consisting of a pressure gauge, safety valve and air vent (for a closed system).

Operating rules

To light the boiler, use paper, wood chips, and dry wood. Place them on the grate, set them on fire and let them burn. After this, you can cover the main fuel with a layer of 5-6 cm, and after 20 minutes add more. It is necessary to maintain a layer thickness of about 15 cm.

When the water in the system warms up to the desired level, you can reduce the air supply by closing the damper on the ash pan door. In order for the boiler to burn longer at night, the grate must be cleaned, ash and slag removed, after which the fuel is ignited and the draft is reduced by closing the damper.

Using a heating element will not allow the coolant temperature to drop to a critical level. The ash pan should be cleaned regularly throughout the day, which will help maintain the draft necessary for combustion.

Advice! While the boiler is operating, its surfaces may become hot. Be careful when adding fuel and protect your hands when opening and closing the loading door.

• Do not allow water to boil in the system. Its temperature should not exceed 85 °C at the boiler outlet.
• If a knock is heard in the system, it is necessary to urgently stop the boiler, for which all the coal is removed from the firebox. When the water in the system has cooled to 60 °C, you need to restore its quantity, after which you can light the boiler again.
• During frosts, if the heating system is not used, the water must be drained.

Solid fuel boilers Hephaestus, produced in Novosibirsk, with traditional way burning fuels have a low price and are available to the general population. They are quite reliable, economical and have an attractive appearance, as evidenced by consumer reviews. They can be used in water heating systems with natural or forced circulation.

Gefest-profi U boiler series- these are boilers for universal use, long burning. Designed to burn all types of solid fuels as efficiently as possible (which is important even with high humidity). Combustion is carried out thanks to direct pyrolysis, when air is distributed over the afterburning zones. The unique convective design ensures efficiency (90-93%) and, importantly, low flue gas temperatures (70-120) °C. 20% power reserve. The large loading chamber allows you to load the boiler with fuel 1-2 times within 24 hours. There is no equipment condensation when low temperatures coolant.

Boilers of the “Gefest-profi” type equipped with an inflatable fan and a microprocessor control unit, which allow you to control the boiler power and coolant speed. And they are representatives of a new generation of boilers with a patented convection system, with smoke channels located at different angles of attack.

The design of the boiler allows the use of any type of fuel: Staub, coal, peat, wood. The use of a distributed air supply system to the combustion zone allows you to effectively control the combustion process various types fuel, and also allows you to control the process of fuel combustion during various modes boiler operation.

The boiler is equipped with a heat exchanger of certified steel 4-6 mm thick, a welded structure, closed from the inside with a water jacket, reinforced with pins and surrounded by sheets of steel. The boiler heat exchanger is a multi-stage design of smoke channels.

The boiler firebox is a filling chamber equipped with steel water-filled grates. There is an ash pan under the heat exchanger. The placement of filling doors, scoop doors, and the ash pan door allows quick access to the firebox for cleaning or ignition.

Wide, angled filling doors make loading fuel easier. Additionally, there are cleaning doors that allow cleaning the boiler smoke channels.

The air necessary for the correct combustion process is supplied by a fan thanks to a system of inflatable channels located directly in the area of ​​​​the loaded fuel.

The microprocessor controller constantly measures the temperature of the water in the boiler and sets the fan pressure accordingly, regulating the amount of air required for the combustion process.

In boilers "Gefest-profi" The regulator controls the boiler temperature based on the PID algorithm. (PID = VO means “proportional = proportional”, “integral = integral”, “derivative = differential”. These three parameters describe the simplest elements of a PID controller. Each of these elements performs its own task and has its own specific effect on the functioning of the system. In In a typical PID controller, these elements operate with a combination of both input control parameters and feedback signals from the controlled device (the control object, hereinafter simply the device). The outputs of these elements add up and form a control signal for the device.)

The microprocessor ensures constant operation of the boiler at the specified temperature of 85 ° C. The maximum water temperature in the boiler is 90 ° C. If this temperature is exceeded, the regulator turns off the air blowing.

Hot gases pass through a steel heat exchanger where, having given off heat, they are cooled. Cooled gases exit the boiler and are connected to the smoke pipe through a chimney. A draft control valve is installed in the smoke pipe, designed to reduce the chimney draft if necessary. The space between the boiler heat exchanger and its body is filled with non-flammable heat-insulating material - mineral wool 40-45mm thick. The temperature of the water in the boiler can be monitored using a thermometer installed on the boiler.

A simple scheme, but it significantly improves the operation of the boiler. It is equipped with a mixing circuit and taps, with the help of which the amount of coolant entering the feeding circuit is regulated. This scheme eliminates the possibility of condensation forming on the walls of the boiler. The advantage of this connection scheme is that the coolant temperature is heating devices may be significantly lower than the temperature of the coolant in the boiler.

Gefest boiler maintenance

Repair and maintenance of the heating system is carried out by the owner of the property or a service company. The boiler requires periodic cleaning and storage.

Cleaning the surface of the furnace walls and secondary air nozzles is carried out through the hatch. 8.2. Cleaning the surface of the grate pipes is carried out through the slag removal hatch (screw hatch). 8.3. Cleaning the walls of the heat exchanger and chimney is carried out through the upper hatches for cleaning the channels. 8.4. Slag removal, after cleaning the walls of the heat exchanger, is carried out through the lower side hatches. 25 8.5. It is also necessary to periodically clean the fan and measuring and control devices to prevent dust from accumulating on these boiler elements. After the end of the heating season, there is no need to drain the water from the boiler, but the firebox and smoke channels should be thoroughly cleaned. In the future, all work related to checking, cleaning and repairing the gas duct must be carried out only by the production and operational organization. To extend the life of the boiler, it is recommended to keep the boiler open during downtime to allow air to enter the boiler, and during storage it is recommended to dry it.

Introduction Choosing a boiler The boiler power required to heat a house is determined based on the size of the house, the thickness and material of the walls, the size and number of windows, winter temperature and other factors. Exact calculations are made by heating system designers.

Approximate calculation: for every 10 meters of square area of ​​the house, with a ceiling height of 2.7 meters, 1 kW of power is required. (For example, a house with an area of ​​100 square meters requires a boiler with a power of 100/10=10 kW, and a house with an area of ​​300 square meters requires a boiler with a power of 300/10=30 kW.) Attention! An approximate calculation is provided for preliminary assessment and is a recommendation. The approximate power calculation is based on statistical experimental data, but has a fairly high degree of reliability.

This operating manual is intended to familiarize you with the design, purpose and methods of safe use of a steel heating boiler (hereinafter referred to as the boiler) and applies to heating boilers.

Description and operation Purpose The steel heating boiler is intended for heating individual residential buildings and buildings for public utility purposes with a total area of ​​up to 200 m2 with a ceiling height of about 2.7 m, equipped with water heating systems with natural or forced circulation.

The principle of operation of the boiler is based on the transfer of thermal energy released during fuel combustion to the coolant - water. As a result of combustion, the walls, lid and partly the bottom of the firebox and the surfaces of the pipes heat up and transfer heat to the water circulating in the water jacket and inside the pipes, which exits through the supply pipe at the top of the boiler. Return water enters the boiler through the return pipe in the lower part of the side wall.

Fuel combustion occurs in a firebox inside the housing. Air enters the combustion zone through the grate.

The amount of air is adjustable:

Manually using the handle 11, tightening or unscrewing, thereby changing the tilt of the damper 9;

Automatically using a draft regulator (the draft regulator is not included in the boiler package) The draft regulator is installed in pipe 15 at the outlet of the boiler body and performs the following functions - reading the water temperature in the heating system and, if necessary, adjusting the supply of primary air for combustion under the boiler grate, while opening or closing the damper. Thus, it became possible to regulate the combustion intensity by the position of the control valve. The temperature regulator is connected to the damper 9 by a special chain attached to the lever of the damper 10 of the ash pan door 12 in such a way that it is possible to adjust its tension.

The boiler design provides for the installation of a 4 kW heating element unit. It can be used to heat water in the heating system, both when burning fuel in the boiler, and independently. The heating element in the block is powered separately to a 220 V network.

The heating element unit must be connected using a cable with a cross-section copper wire not less than 4 mm2 and 30 A circuit breakers.

Attention: the boiler body must be grounded!

Chimney installation

For a solid fuel boiler, it is allowed to use a brick chimney with a smoke channel cross-section of 150 cm2; the smoke channel must have a constant cross-section along its entire length.

The height of the chimney, counting from the grate, should be at least 5 m.

The height of the chimneys.

Placed at a distance equal to or greater than the height of a solid structure protruding above the roof, the following should be taken:

At least 500mm above a flat roof;

At least 500 mm above the roof ridge or parapet - when the pipe is located at a distance of up to 1.5 meters from them;

Not lower than the ridge of the roof or parapet - when the pipe is located from them at a distance of 1.5 to 3 meters;

Not lower than a line drawn from the ridge downwards at an angle of 100 to the horizon when the pipe is located at a distance of more than 3 m from it.

When a chimney passes through interfloor ceilings, the distance from the outer surfaces of the pipe to wooden structures not less than 380mm.

You cannot embed a chimney into concrete and brick structures. Fill the gap between the sleeve and the structure with thermal insulation (expanded clay, silica wool...). Holes in the walls must not be used as part of the chimney (the chimney liner must pass through).

Heating system installation

For piping a heating system boiler with a circulation pump, use pipes with a cross-section of at least DN 32 (1 1/4), for wiring - at least DN 20 (). The circulation pump must be installed on a parallel line to ensure natural circulation during a power outage. The outlet manifold must have a cross-section of DN 32 mm (1 1/4) to the safety device of the open expansion tank or safety valve.

As a rule, it rises vertically above the heating system; at the top point, an open expansion tank is installed (or a safety group for a closed system) and the coolant is dismantled after passing the top point.

Provide air bleed valves from the heating system.

To piping a boiler with natural circulation (Fig. 4), use pipes with a cross-section of DN 32 mm (1 1/4), and assemble the system with slopes that ensure complete drainage of water through the drain valve on the return pipe, and expulsion of air from the system when filling it water from bottom to top.

Threaded connections are sealed with winding: threads impregnated with TangitUniLock, Loctite@55 or sanitary flax, applied to the surface of the winding and the inner surface of the boiler threaded fitting, plumbing silicone gel or special paste.

In order to prevent scale formation on the heated surfaces of the boiler jacket, it is necessary to carry out chemical treatment water. The choice of water treatment method for feeding boilers and heating systems should be made by a specialized (design, commissioning) organization.

Water for feeding open heating supply systems must meet the requirements of GOST 2874 - Drinking water.

Attention:

1) Operation of boilers without pre-boiler or intra-boiler water treatment is prohibited.

2) The boiler does not work alone, but as part of the heating system, and the operation of the boiler depends on how the heating system is installed.

PREPARATION OF THE HEATING SYSTEM AND BOILER

1. The boiler must only be operated connected to a heating system filled with coolant. GOST 2874 water with a water hardness of up to 5 mg-eq/l and antifreeze based on non-toxic propylene glycol can be used as a coolant.

2. Fill the open heating system with coolant until it emerges from the overflow pipe of the expansion tank.

3. Filling and replenishing the open heating system with water from the water supply system, in order to avoid damage to the boiler, is done through a pressure reducer that reduces the water pressure to 2.5 kgf/cm2. Fill an open heating system with water from a water supply without a pressure reducer through an expansion tank, after which make sure there are no air pockets.

4. When the heating system is filled with coolant, the convective surfaces of the chimney acquire a slightly convex shape. Bending of surfaces is not a malfunction, does not interfere with the use of the heating apparatus for its intended purpose, and does not affect the tightness, technical parameters and characteristics of the apparatus.

Boiler operation

1. When operating the heating system, the coolant level in the open expansion tank should not fall below its height and must be maintained by periodically adding coolant.

2. It is prohibited to use water from the heating system for household needs, as this may cause the water level to drop and the circulation to stop.

3. Check whether the tap on the return line of the heating system is open and check for the presence of draft.

4. Ignition:

Open the door flap.

Fill the boiler firebox with kindling material (paper, dry wood chips, firewood), placing it on the grate.

Ignite the kindling material.

When normal combustion of the kindling material is achieved, pour a layer of main fuel 50-60 mm thick onto the burning firewood through the loading hatch.

Attention! It is prohibited to open and close the loading hatch without special hand protection.

Add another portion of fuel (after 10-20 minutes) when the first layer of main fuel flares up. For the boiler to operate in nominal mode, it is necessary to maintain a layer of fuel on the grate of about 150 mm. It is possible to force the furnace (that is, increase the air supply) only after the formation of a small slag cushion.

To prevent smoke from escaping into the room through the loading hatch during the process of adding successive portions of the main fuel, it is necessary to close the ash pan door damper. After loading a portion of fuel, open the door damper.

5.Operation:

After reaching the desired heating water temperature, it is recommended to reduce the amount of air supplied. Fine adjustment of power is carried out using the ash pan door flap, with the help of which the air supply under the grate is regulated manually or using installed regulator traction.

Depending on the heat demand and combustion intensity, the boiler must be refilled with fuel. Add fuel so that the layer height is uniform throughout the entire depth of the boiler.

For long-term burning at night, it is necessary to clean the grate, ignite the added fuel well, and then reduce the power of the boiler by reducing the draft using the damper of the chimney pipe (attention! It is not recommended to completely close the damper during combustion) and by closing the air supply damper.

In the morning, update the boiler operation by opening the smoke damper, and poke through the grate with the ash door open.

Ash from the ash pan must be removed during boiler operation several times a day, depending on the fuel used, since a filled ash pan prevents the correct distribution of combustion air under the fuel and contributes to uneven heating of the fuel on the grate. All residues in the firebox, primarily slag, are removed before each new kindling and when updating the boiler operation.

Ash must be placed in non-flammable containers with a lid. During work, you must use protective equipment and maintain personal safety.

When burning coke or anthracite, it is necessary to regularly clean the boiler walls inside the firebox, the boiler chimneys and the smoke pipe once a month.

When burning coal, clean it once a week.

When using fuel with a high yield of volatile components, tar deposits may occur on the walls of the boiler, which must be removed by scraping or burning with dry wood (or coke) when the boiler is operating at maximum operating temperature.

ATTENTION! When the boiler is ignited for the first time, water (usually black) may flow from under the ash drawer.

Most often, this manifests itself when the heating system is first started, when moisture from the air and fuel condenses on the cold walls of an unheated boiler and stops after the heating system, boiler walls and chimney walls have warmed up.

It may take several days of boiler operation to completely stop the formation of condensation.

Boiling of the coolant in the boiler and heating system is not allowed.

When operating the boiler, the temperature of the coolant at the outlet should not exceed 850C. If there is a knock in the system (hydraulic shock due to steam formation), it is necessary immediately! Remove unburned coal (heat) from the firebox, allow the coolant to cool to a temperature of 60-700C, then replenish the system with coolant and heat the boiler again. IT IS PROHIBITED to extinguish fuel with water, because this leads to the destruction of the grate.

IN winter time, if you need to stop firing a boiler that is not equipped with a heating element unit for more than a day, it is necessary, in order to avoid freezing, to completely empty the heating and hot water supply system of water.

Let's look at the main components and operating principles of Gefest gas condensing boilers. Two models of the device, Star and Econom, are produced. There are several models of different power in the line: Hephaestus 26, 20, 32 and 16 kW.

From the outside, the gas boiler is covered with a protective white enameled metal casing. At the bottom there is a control panel with a display, temperature regulator, buttons for turning on and controlling the device and a pressure gauge. The casing can be removed without the help of screwdrivers; it is secured with latches.

Heating pipes, as well as hot water supply and gas, are supplied from below. The purpose of each is signed on the bottom cover. There is also a cable connecting to the electrical network with a residual current device.

The gas enters a stainless steel burner, which consists of a base, a tube, nozzles and burner rows. It is ignited by piezoelectric elements, the fuel burns and at the same time heat is released, which is transferred to the primary heat exchanger.

The boiler has two circuits - for heating and providing hot water. The primary heat exchanger is a coil-shaped copper pipe to which fins in the form of copper plates are soldered. The hot water heat exchanger consists of a large number of plates that are soldered together. It is also made of copper, has good thermal conductivity and large area heat exchange.

The combustion chamber is closed type. Therefore, a fan is additionally installed, which removes combustion products through a coaxial chimney. Due to the pressure created inside the combustion chamber, the air necessary for combustion enters it. The fan is modulated with rotation speed adjustment. The chimney pipe is made of stainless steel.

Stainless steel chimney

At the bottom right there is a circulation pump with three operating speeds. It pumps coolant through pipes and radiators. Additionally the pump is equipped automatic air vent, which removes air from the coolant during startup and during operation.

An expansion tank with a capacity of six liters is located on the rear wall. It compensates for the increase in coolant volume as its temperature rises. Inside, it is divided into two parts with an elastic membrane between them. The first part is filled with nitrogen, and the second with coolant. Nitrogen, compressing, compensates for the additional volume of coolant when heated.

The boiler is fully equipped with all necessary safety devices. The gas proportional valve smoothly ignites the boiler at minimum gas pressure and maintains the set heating output of the equipment, receiving signals from the control panel. When the power goes out or goes out, it immediately shuts off the gas supply. Protection against overheating, low water pressure and defrosting is installed.

Basic error codes

e1

Error e1 means that in circulation system coolant pressure too low. The reason for this may be a blockage in the pipes, insufficient water, problems with the circulation pump or poor contact in the connecting wires.

Gas boiler circulation pump

It is necessary to open the make-up valve and clean the pipes. Using a screwdriver, turn the pump axis several times in different directions. Check the quality of the contacts of the connecting wires and, if necessary, restore the connection.

e2

Error e2 indicates problems in the operation of the combustion and ignition system. Most likely, the control unit has stopped working or there is no voltage at the solenoid valve. The ignition device, ignition electrode may also fail, or the gas valve may be faulty. The error can be corrected by replacing the control unit, ignition device or gas valve.

e6

Error e6 means a breakdown of the combustion products exhaust system. The fan may be faulty or not receiving electricity. An error occurs if the exhaust pipe is clogged or is too long. In this case, you need to check the wiring of the fan and its serviceability and, if necessary, replace it. And also check the draft in the chimney and its cleanliness.

e7

Error e7 lights up when the coolant overheating protection sensor is triggered. The malfunction is in the sensor itself or its control circuits. The control board or one of the temperature sensors may also be inoperative.

Gas boiler temperature sensor

The coolant also overheats because the pipeline uses too small a cross-section of pipes or the area of ​​the heated room less power boiler It is necessary to check the operation of the sensor, circuit and control board. If necessary, increase the diameter of the pipes and adjust the power.

ee

Error ee means incorrect digits. You need to re-enter.

Other faults

In addition to the fact that the Hephaestus boiler displays error codes on the display, breakdowns are possible that can be diagnosed in other ways.

After a long period of equipment downtime, the circulation pump may not start. In this case, the anti-blocking function was not performed. Unscrew the plug on the pump and use a screwdriver to turn the shaft several times clockwise and counterclockwise.

Over time, scale accumulates in the hot water heat exchanger, which leads to a decrease in pressure hot water. The rate at which deposits appear is affected by water hardness and too high a heating temperature.

Gas boiler heat exchangers

It is recommended to heat the water to 45 degrees, this is enough for household use and extends the operating time of the device. To correct the problem, we disassemble the boiler, disconnect and remove the heat exchanger. Next, fill it with a hot solution of water with citric acid or vinegar and leave it for a day. After this, we actively rinse.
