Consider the main components and the principle of operation of Gefest gas condensing boilers. The device is produced in two models Star and Econom. There are several models of different power in the line: Hephaestus 26, 20, 32 and 16 kW.
Outside, the gas boiler is closed with a protective white enamelled metal casing. In the lower part there is a control panel with a display, a temperature regulator, buttons for switching on and controlling the device and a pressure gauge. The cover is removed without the help of screwdrivers, it is fixed with latches.
Heating pipes, as well as hot water supply and gas pipes are supplied from below. The purpose of each is signed on the bottom cover. There is also a cable for connecting to the mains with a residual current device.
The gas enters a stainless steel burner, which consists of a base, tube, nozzles and burner rows. It is ignited by piezoelectric elements, the fuel burns out and heat is released, which is transferred to the primary heat exchanger.
The boiler has two circuits - for heating and providing DHW. The primary heat exchanger is a coil-shaped copper tube to which fins in the form of copper plates are soldered. The hot water heat exchanger consists of a large number plates that are soldered together. It is also made of copper, has good thermal conductivity and a large heat exchange area.
Closed combustion chamber. Therefore, a fan is additionally installed that removes combustion products through a coaxial chimney. Due to the pressure created inside the combustion chamber, the air necessary for combustion enters it. Modulating fan with speed control. The chimney pipe is made of stainless steel.
At the bottom right there is a circulation pump with three operating speeds. It pumps the coolant through pipes and radiators. Additionally, the pump is equipped with an automatic air vent, which removes air from the coolant at startup and during operation.
An expansion tank with a volume of six liters is located on the rear wall. It compensates for the increase in the volume of the coolant with an increase in its temperature. Inside, it is divided into two parts with an elastic membrane between them. The first part is filled with nitrogen, and the second with a coolant. Compressing, nitrogen compensates for the additional volume of the coolant when heated.
The boiler is fully equipped with all necessary safety devices. The proportional gas valve smoothly ignites the boiler at minimum gas pressure and maintains the set heating capacity of the equipment, receiving signals from the control panel. In the event of a damping or a power outage, it immediately shuts off the gas supply. Installed protection against overheating, low water pressure and defrosting.
Major error codes
e1
Error e1 means that the coolant pressure in the circulation system is too low. This can be caused by 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 tap, clean the pipes. Use a screwdriver to turn the pump shaft 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 on the solenoid valve. Also, the ignition device, ignition electrode 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 removal system. The fan may be defective or not receiving electricity. Causes an error that the chimney is clogged or is too long. In this case, it is necessary to check the fan wiring 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 sensor overheating of the coolant is triggered. The fault is in the sensor itself or in its control circuits. Also, the control board or one of the temperature sensors may be inoperative.
Gas boiler temperature sensor
The heat carrier also overheats due to the fact that too small a cross-section of pipes is used in the pipeline or the area of the heated room is less than the power of the 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 the wrong set of numbers. It is necessary to re-enter.
Other malfunctions
In addition to the fact that the Hephaestus boiler displays error codes on the display, breakdowns are possible that are diagnosed in other ways.
After a long period of inactivity of the equipment, the circulation pump may not start. In this case, the anti-blocking function was not performed. Unscrew the plug on the pump, use a screwdriver to turn the shaft several times clockwise and counterclockwise.
Over time, scale builds up in the hot water heat exchanger, which leads to a decrease in the pressure of hot water. The rate of formation of deposits is influenced by the hardness of the water and too high a heating temperature.
Gas boiler heat exchangers
It is advised to heat the water to 45 degrees, this is enough for household use and extends the operating time of the device. To fix the malfunction, we disassemble the boiler, disconnect and take out the heat exchanger. Next, fill it with a hot solution of water with citric acid or vinegar and leave it for a day. After that, we actively rinse.

The device and principle of operation of the boiler Gefest-2.5-95TLPH (KVm-2.5KB)
Boiler Gefest-2.5-95TLPH (KVm-2.5KB) is a structure, the main elements of which are a boiler block and a mechanical furnace. The boilers operate with a balanced draft, which is provided by a VDN blower fan, KZG-280-AK54-02 fan and a smoke exhauster.
The boiler block Gefest-2.5-95TLPH (KVm-2.5KB), assembled on a support frame, is a gas-tight welded structure, consisting of a pipe system with a convective heating surface, and has a frame with thermal insulation and removable decorative sheathing.
The combustion chamber of the boiler Gefest-2.5-95TLPH (KVm-2.5KB) (except for the hearth) is completely shielded by gas-tight panels welded from pipes with a diameter of 51x2.5mm with a pitch of 80mm and spacers (fins).
The convective heating surface (CC) consists of packages that can be easily dismantled if necessary. In the lower part of the convection block there is an ash bin with a manhole for cleaning ash deposits and inspecting the pipes of the convective bundle.
The gases are vented through a flue in the upper part of the rear wall of the boiler.
To control the operation of the Gefest-2.5-95TLPH (KVm-2.5KB) boiler, to ensure the design operating modes and safe operating conditions, the boiler is equipped with the necessary safety and shut-off valves, instrumentation and safety devices, which are installed according to the valve layout.
The shut-off valves are used to drain water from the Gefest-2.5-95TLPH boiler (KVm-2.5KB) into the heating network, supply return water to the boiler, drain water from the boiler, for periodic blowdown and removal of sludge. Control and measuring devices (thermometers and manometers) measure pressure and temperature at the inlet and outlet of water from the boiler. Safety devices ensure that the fuel supply is cut off when the temperature and pressure limits of the water in the boiler are reached. Tubes with valves DN15 are used to remove air from the boiler.
The boiler block Gefest-2.5-95TLPH (KVm-2.5KB) is installed on the furnace frame (TLPH). The firebox is mounted before the unit is installed.
Mechanical furnace with a belt grate for forward running (TLPH) consists of a coal box, a frame with a drive, driving and driven shafts moving the belt grate, consisting of three types of grates: extreme, leading and driven. The fuel is supplied by a coal feed conveyor and through the coal box it flows by gravity onto the grate, where it is burned in a layer of 100-200 mm. A certain thickness of the fuel layer on the grate is maintained by means of a layer regulator in the carbon box and is produced manually by means of flywheels through worm gears. Chambers (zones) are arranged under the grate, where the necessary combustion air is supplied. The air supply must be continuous (otherwise the layer is sintered and the grates are burned out) and is regulated by the opening value of the air dampers. Air under the grate is supplied from the VDN fan. Secondary blast air is supplied to the upper front and lower rear parts of the furnace from the KZG-280-AK54-02 fan.
The removal of slag from the grate is due to the movement of the grate, which is set in motion by a drive. Slag removal from the slag channel is carried out by the ash removal conveyor.
The firebox has its own frame, independent of the boiler. The firebox frame consists of two cheeks connected by transverse beams. The frame is mounted on shoes and has free expansion in the longitudinal and transverse (from the drive) directions. For lifting the combustion block with lifting means, there are load brackets, which are cut off after installation.
Boiler block Gefest-2.5-95TLPH (KVm-2.5KB), firebox, fans are delivered in separate cargo items. Automation set, accessories are delivered packed in a box.
At the request of the Customer (under an additional agreement), the boilers are completed with auxiliary equipment for the boiler room (smoke exhauster, pump group, ash collector or cyclone, coal supply conveyor and ash removal line).
Transportation of boilers can be carried out by all types of transport.

Boilers type "Gefest-profi" equipped with an inflatable fan and a microprocessor control unit, which allow you to control the boiler power and the speed of the coolant. 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 of various types of fuel, and also allows you to control the fuel combustion process under various operating modes of the boiler.
The boiler is equipped with a heat exchanger of certified steel with a thickness of 4-6 mm, a welded structure, closed from the inside by a water jacket, reinforced with pins and surrounded by steel sheets. The boiler heat exchanger is a multi-stage design of the flue ducts.
The boiler furnace is a charging chamber equipped with steel water-filled grates. There is an ash pan under the heat exchanger. The location of the filling, skimming doors, and the ash pan door allows quick access to the firebox for cleaning or lighting.
Wide, angled loading doors facilitate fuel loading. Additionally, there are cleaning doors that allow cleaning the boiler flue channels.
The air necessary for the correct combustion process is supplied by a fan thanks to a system of inflatable ducts located directly in the area of the loaded fuel.
The microprocessor controller constantly measures the temperature of the water in the boiler and accordingly sets the fan blowing force, regulating the amount of air required for the combustion process.
In boilers "Gefest-profi" regulator, controls the boiler temperature based on the PID algorithm. (PID = BO stands for "proportional = proportional", "integral = integral", "derivative = differential." In a typical PID controller, these elements operate with a combination of both input control parameters and feedback signals from a controlled device (a control object, hereinafter simply a device.) The outputs of these elements are added together and form a control signal for the device.)
The microprocessor ensures the constant operation of the boiler at the specified temperature of 85 ° C. The maximum temperature of the water in the boiler is 90 ° C. When this temperature is exceeded, the regulator turns off the air supply.
Hot gases pass through a steel heat exchanger where, after giving off heat, they are cooled. The cooled gases leave the boiler and are connected to the flue pipe through the chimney. A draft control valve is installed in the chimney, designed to reduce the chimney draft if necessary. The space between the boiler heat exchanger and its body is filled with non-combustible 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.

Uncomplicated scheme, but significantly improves the operation of the boiler. It provides for a mixing circuit and taps, with the help of which the amount of coolant entering the flue gas circuit is regulated. This scheme excludes the possibility of condensation formation on the boiler walls. The advantage with such a connection scheme is that the temperature of the coolant in the heating devices can be significantly lower than the temperature of the coolant in the boiler.
Boiler service Gefest
The heating system is repaired and maintained by the home owner or service company. The boiler needs regular cleaning and storage. This is essential for proper operation and efficient combustion of fuel. It is allowed to start cleaning the boiler only after it has completely stopped (see section 6.4. Stopping the boiler). 8.1. Cleaning of the surface of the furnace walls and secondary air nozzles is carried out through the hatch. 8.2. The surface of the grate pipes is cleaned through the slag removal hatch (shurovka hatch). 8.3. The walls of the heat exchanger and the chimney are cleaned through the upper channel cleaning hatches. 8.4. Removal of slag, 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 in order to prevent the accumulation of dust on these elements of the boiler. After the end of the heating season, it is not necessary to drain the water from the boiler, but the furnace and flue ducts must be thoroughly cleaned. In the future, all work related to checking, cleaning and repairing the gas duct should be carried out only by the production and operating 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 it is recommended to dry it during storage.
If just a few decades ago it was believed that there was no worthy competitive replacement for European heating equipment, today the domestic manufacturer is gradually gaining its positions. Gas boilers Hephaestus convincingly prove that water heating units manufactured at Russian factories are no worse than their foreign counterparts.
Types of gas boilers from Gefest
The equipment of the Hephaestus company meets all the requirements that apply to heating equipment:- Reliability - trouble-free operation is ensured by Italian gas automatics.
- Simplicity of design- since the number of additional units is minimized, breakdowns are practically excluded.
- Easy to operate and maintain- all the necessary components can be easily purchased at the nearest heating equipment store.
- Wall mounted boilers- save space, in most cases they have two circuits and are dependent on the availability of electricity.
- Floor standing boilers- the most productive heating equipment of the Hephaestus company, the main purpose of which is to heat the coolant. The DHW circuit is either provided in the basic configuration or manufactured additionally, using a built-in or remote indirect heating boiler.
All Hephaestus boilers, regardless of the configuration, are equipped with sensitive Italian automation that continues to work even when the gas pressure drops to 4 mbar.
Wall mounted boilers
The company focuses on the manufacture of powerful floor-standing units, therefore mounted boilers are presented in only a few modifications. Among them are:
Installation of the Hephaestus mounted boiler is carried out using the anchor bolts included in the package. For connection, taps for two heating circuits (central and "warm floors") and hot water supply are provided.
Floor equipment Hephaestus
Floor-standing units (in comparison with mounted boilers), although they do not have most of the functionality, are distinguished by high performance and reliability. The following modifications are popular:
The technical characteristics of the Hephaestus floor-standing boiler imply connection to a classic chimney. Traditionally, an open combustion chamber and an atmospheric burner are used. Household gas floor boiler Hephaestus flow-through type can be used exclusively for the needs of hot water supply.
Operational Features
As already noted, boiler maintenance does not require a large investment of funds and efforts. It is carried out quickly due to the simplicity of the design and free access to the nodes. Service may be required in the following cases:
In non-flue boilers, reverse draft sensors are installed to prevent the spontaneous extinction of the flame; other monitoring equipment is also used.
A drop in gas pressure or a decrease in the volume of the coolant can cause the automatic operation and an emergency stop signal. The solenoid valve of the boiler shuts off the gas supply and thus prevents the accumulation of explosive substances in the room.
The duration of the operation of the boilers largely depends on the installed hydrogroup of the boiler. Softening water and removing coarse particles and calcium deposits protects the heat exchanger from overheating and extends its life.
Why the Hephaestus floor boiler goes out
One of the most common problems of the owners of Hephaestus boilers, judging by the reviews, remains a malfunction, due to which the flame goes out. What could be the cause of the attenuation?- Violation of the technology for installing a coaxial chimney- the consequence of non-compliance with the requirements is an increased volume of flue gases accumulating in the chimney, which leads to spontaneous attenuation as a result of the automatic operation.
- Wind - boilers with a closed combustion chamber cannot be extinguished even from a strong gust of wind, since a gas reverse draft valve is provided in the design. For heat generators with an open combustion chamber, such a sensor is not provided (can be purchased and installed separately).
- Violation of operating conditions- if the igniter goes out, the reason does not always lie in a malfunction of the automation, probably a problem with power surges or gas supply. For volatile models, it is recommended to install a UPS and a pressure stabilizer.
