Ferroli gas water heater electrical circuit. We repair the gas column ourselves. The gas water heater does not heat the water well

Today we will consider the types of gas heaters of the Italian manufacturer Ferroli. So, there are two types of Ferroli boilers: wall and floor. Units that are suspended are also divided into two groups - conventional and condensing. The latter are characterized by high efficiency.

Ferroli wall mounted gas boilers

Wall heater Italian company Ferroli.

Ferroli wall-mounted boilers are available in different configurations and capacities, so you can choose a unit according to your requirements and budget. The first characteristic is the number of circuits. So, heaters can work not only to heat water in the heating system, but also simultaneously supply the house with hot water. Accordingly, single-circuit and double-circuit boilers are distinguished.

The second aspect is the type of combustion chamber and its configuration. The combustion chamber may be open or sealed. Open combustion chambers, like a conventional stove burner, burn the air out of the room (there is no fire without oxygen). Sealed chambers draw in air from the street through a special chimney called.

A heat exchanger (one or two) is installed in the combustion chamber. One heat exchanger (bithermic) is a pipe in a pipe, into which pipes are cut for separate smoke removal. The heat exchanger is made of copper. If there are two heat exchangers, then they are separated from each other. The primary is made of copper and the secondary is made of stainless steel.

The richer the equipment, the more expensive the repair of Ferroli gas boilers.

Complete set of Ferroli gas boilers according to the instructions:

• heat exchanger (one or two);
• gas valve - Siemens or HoneyWell;
• three-speed Wilo;
• branch pipes for smoke removal - separate smoke exhaust system;
• Control block.

There are models with and without LCD display. The display shows information about the parameters of the heater and errors that occur during operation. The display lights up blue. The DivaTop 60 model is available with a built-in 60 liter boiler.

The efficiency of the Ferroli wall-mounted heating boiler of any model is approximately 93%. The minimum power is 7.2 kW, the maximum is 40 kW. The heat carrier for high-temperature heating systems, the unit heats up to 85 degrees, and water for hot water supply - up to 55 degrees. Boilers operate on natural and liquefied gas. The nominal energy consumption is indicated in the passport for each model. The inlet gas pressure must be at least 20 mbar for natural gas and 37 mbar for liquefied gas.

Floor heaters Ferroli

Inflatable burner must be purchased separately.

Floor cast-iron boilers are available with a built-in and with a removable (inflatable) burner. To begin with, consider models with a built-in burner. The equipment of the simplest boilers (up to 1 thousand Euros) is very modest:

• single stage burner;
• cast iron heat exchanger;
• gas valve HoneyWell or Sit;
• connectors for additional equipment (pump, thermostat).

Boilers priced from 1 thousand euros, in addition to the standard set, are equipped with a display, connectors for connecting a three-way valve, a boiler pump, outdoor temperature sensors, and boiler sensors. Thanks to this set of options, the heater itself can control the degree of heating of the coolant according to weather conditions. The complete set of each model is indicated in the instruction manual for the Ferroli boiler.

Units over 2 thousand Euros, for example Pegasus-DK, have a built-in boiler for 130 liters and a 12 liter expander, two pumps, a magnesium anode is installed in the boiler. A magnesium anode is needed so that the boiler tank does not rust. This is a consumable material, the anode must be changed periodically (as it splits). Heaters for 3 thousand Euros (Pegasus 2S and PegasusF3 N2S) have the same equipment as the cheapest models, with the exception of the burner - in expensive units it is two-stage. This allows you to expand the range of boiler power adjustment.

If any problems arise during the operation of the Ferroli gas boiler, a fault code is displayed on the liquid crystal display.

The peculiarity of boilers with a removable inflatable heater is that they can operate on both gas and diesel fuel, it depends on the type of burner:

• for gas - Sun M;
• for diesel - Sun G.

In the Atlas heater it is possible to connect an internal one or two-stage gas burner instead of an external air burner. In a rich configuration, for example, Atlas DK, there is a built-in 10 l expansion tank and a 100 or 130 l boiler, two pumps, and a liquid crystal display. The external inflatable burner is not included and is supplied separately.

Ferroli condensing boilers

All condensing boilers with closed combustion chamber.

If you look through the operating instructions for the Ferroli gas boiler, then among the condensing units there are the following differences:

• the number of heat exchangers - one or two;
• heat exchanger material - stainless steel or aluminum;
• burner material - ceramic or steel;
• the presence of a boiler;
• the presence of an air separator.

All heaters have a display, a bypass and a built-in modulating or three-speed circulation pump (except for the Energy Top W model, which does not have a pump). Condensing boilers have an efficiency of 109%. The minimum power is 2.1 kW, and the maximum is 79.5 kW. Prices range from 730 to 3000 Euros.

Ferroli F24 DOMIproject

Ferroli boiler has a modern design. It is produced using modern technologies, differs from others in workmanship and reliability. This is a high efficiency gas heat generator, made for heating, running on both natural gas and petroleum gas. Produces hot water.

The boiler body has a copper plate heat exchanger. It provides excellent heat transfer regardless of operating conditions. The housing also includes an electronic burner that is electrically ignited and an ionization system that controls the flame.

The operation of the boiler is automated with the help of microprocessor control and control of the diagnostic system. For hot water supply, the DHW system is controlled automatically and without interruption.

To obtain the desired room air and hot water temperature, these parameters must be adjusted automatically. The boiler operates year-round with a regulating system and control.

The boiler has a display, which gives all the information about the functioning of the unit. Faults in operation are shown on the display and can be automatically corrected.

Control Panel

The control panel has a button with many functions, two knobs, a display with three lights: green, yellow, red. With their help, information about the operation of the Ferroli is displayed. The lights indicate a fault code, which in most cases restart automatically.

Enable and disable

Using the instructions, it is possible to familiarize yourself with how the gas unit starts and turns off. The gas cock located in front of the boiler must be opened. The air that is in the gas pipes must come out. After that, the ferroli is connected to the network, and the knobs of the regulators are set to a certain heating or hot water mode. After a certain request, ferroli will start its work. To turn off, turn the knobs to the minimum position. In this case, the electronic board is not disconnected from the voltage. The frost protection system is active. It ceases to function in the event of a power outage.

Using the remote control instruction, the temperature in the system will be at a certain level and controlled by the room thermostat.

The temperature of the heating system can be from 30°C to 85°C. But the operation of ferroli at temperatures below 45 ° C is not recommended.

The temperature of hot water supply can vary from 40°C to 55°C. By turning the knob, the desired temperature is set. When a remote control is connected, the hot water is adjusted from the remote control.

ECO/COMFORT setting mode

The ferroli has a special device that produces a high speed of sanitary water. In this mode, domestic hot water is supplied to the hot water system without delay.

Maintenance

The ferroli boiler must be systematically maintained. At least once a year. To clean the boiler, use a damp soft cloth and soapy water. Detergents and solvents are not recommended.

Installation

The gas boiler must be installed by professionals who follow the instructions. The water in the boiler is heated to the boiling point, it is connected to the heating system.

The gas boiler has an open combustion chamber. Installation and operation is carried out in well-ventilated rooms, which must comply with UNI-CIG 7129 standards. Considering that the boiler power does not have 34.8 kW, its installation is allowed in any well-ventilated room. The unit is hung on the wall.

Connection types

In order to function perfectly and have a long service life, the hydraulic system of the boiler must be sized to meet the standards of the manual and ensure proper operation and uninterrupted flow of water.

To connect the gas connections, it is necessary to clean the gas pipes. Connection takes place strictly according to current regulations.

In addition, the boiler has an electrical connection, in which it is necessary to correctly connect to the ground loop.

The boiler must be put into operation by highly qualified specialists.

Such a complex device as a geyser serves for quite a long time, maintenance and operation is carried out according to the instructions attached to this unit. But all things deteriorate and sometimes minor or major repairs of gas water heaters or their prevention are necessary. As well as the replacement of some components of the gas column.

Machine description

The internal structure of flow-type gas water heaters is the same and almost does not differ from different manufacturers. The main difference may be in the additional options (display, automatic gas ignition, second temperature sensor, etc.), in the appearance of the device or in the design.

A heat exchanger is installed inside - a finned copper tube through which the water flow moves. The burner standing under the heat exchanger heats the tube and the water passing inside it heats up. With a small pressure of water or its absence, the incoming flow is blocked by a valve (curtain), to which a spark ignition switch is attached. This is for fire safety.

Call the master or repair it yourself

We call the master

To repair a faulty geyser or prevent a gas leak (if you smell), you need to call a gas geyser repairman. But if you decide to call Gorgaz workers, then do not think that they will come right away, sometimes they refuse to come, arguing that the repair should be carried out by the company (or store) that installed the gas water heater.

Attention! Use only companies that have the necessary certifications to work with this equipment.

Now divorced a lot of "left" firms and house calls of workers of such organizations bring a number of other problems. Many craftsmen, seeing your incompetence in this area, find non-existent malfunctions of the geyser or deliberately inflate prices.

Do-it-yourself geyser repair

To improve the safety of the population, it is prescribed that malfunctions associated with gas equipment be eliminated by employees of the relevant service. But there are some problems that you can fix yourself. If you know how to hold the tool in your hands, you can repair the gas column with your own hands.

This is not very difficult if you know the typical problems of these water heaters. Below we will talk about the most common of them and show you how to fix this or that breakdown. And let's start with setting up the unit.

Burner flame height adjustment - the closer to the maximum, the hot water.
Adjusting the water flow - the closer to the maximum, the greater the flow, therefore, the water is colder.
Winter / Summer - the mode of using the column in different seasons. More power in winter than in summer.

Not all craftsmen know how to properly set up a geyser and simply do not do it, leaving it as it is (by default). But we do not recommend leaving the factory settings and adjusting yourself.

Temperature setting

• Set the gas and water supply knob on the heater to minimum.
• Open the gas and water supply valves on the pipelines.
• Open the hot water tap and adjust the water pressure you need using the knob on the gas water heater.
• Wait 1-2 minutes and take the temperature. Using the gas supply knob on the column, increase the flame, thereby raising the water temperature to the desired one.
• When the water temperature is comfortable, you can leave all adjustments alone and use the water.

In the future, you can adjust the temperature with another knob (supply of heated water).

Pressure setting

When adjusting the column, sometimes unpleasant moments arise. A new column either turns on at a very low pressure, or does not want to start at all. It depends on the increased or reduced pressure of water in the pipeline and is eliminated in the following ways.

With our water quality, heat exchangers in gas water heaters become clogged with scale quite quickly and very much, which reduces their thermal conductivity and increases gas consumption.

The longest, in time, process is cleaning the main tube(radiator) from deposits arising from the heating of tap water. If you turn the gas knob to the end, and the water coming out is barely warm, then this indicates that the heat exchanger is clogged with ordinary scale, which does not transfer heat well.

This happens quite often if the geyser is without auto-ignition (with an igniter). Also, scale is formed if you set the water heating temperature too high. The unit overheats, the tube (radiator) heats up to 80-850, which contributes to the rapid (a little over an hour) scale formation. Isn't it better to just turn off the column in time? Then there will be no problems, because 40-600 is enough for all washing and washing processes.

Before starting work on the heat exchanger, check the inlet cock or valve. Maybe the whole reason is in their clogging. But if they are serviceable, it is necessary to get rid of deposits in the tube.

There are two ways to solve the problem with scale. We will consider both options.

Auto

The Cillit KalkEx cleaning system does the job pretty well. With its help, you can quickly clean any boilers from scale. Unfortunately, it is not very accessible to ordinary users of gas water heaters.

This is an expensive method using a special device(Cillit KalkEx) and a set of special preparations for flushing. Your column does not even need to be removed from the wall. Just need to disconnect the water hoses for water (inlet/outlet).

The cleaning device is connected to the column, and it drives the heated reagents in a closed cycle (in a circle). Scale under their action decomposes, is washed out and merges.

Manual

Cheap but long and laborious process. For its implementation, it is necessary to disassemble the water heater almost completely and then rinse it manually.

The following materials and tools will help us with this:

• wrenches (set);
• screwdrivers (phillips and regular);
• paronite gaskets (set);
• rubber hose;
• vinegar essence or antiscale agent.

Disassembly of the gas apparatus

To remove the heat exchanger proceed as follows:

• first block the access of cold water;
• then we remove the external elements that prevent disassembly (knobs of switches, regulators);
• remove the casing, and for this we unscrew the screws located on the rear wall of the unit, lift and remove the cover;
• open the "hot" tap;
• unscrew the supply tube from the heat exchanger and move it away;

Flushing the system

After the water has completely drained, we put the hose on the heat exchanger tube and raise it above the level of the column. Slowly pour the solution we prepared into the hose and leave the column for 4-6 hours.

Next, you need to slightly open the water supply tap and observe the water that will come out of the column, if you saw a lot of scale, then our work was not in vain - we got rid of it. If there is no scale in the outgoing water, then we repeat the whole process again.

The gas stove does not ignite

1. A water heater failure can occur for many reasons. We list the most likely ones:
2. The simplest reason for this trouble is the lack of normal draft in the chimney. If the chimney is clogged and there is no “draught” in it, then the column may not ignite.
3. To check for a malfunction, you can bring a piece of newspaper, a napkin, or a lit match to the chimney. If they tremble, then the thrust is in order. Otherwise, you will need to clean the chimney.
4. If the device (only in units with auto-ignition from batteries or the mains) does not ignite, then the battery is discharged or the wires or the igniter unit are to blame. Eliminated by inserting batteries or checking the electric ignition system.

Failure of the igniter system may occur due to poor pressure water. Open any faucet with cold water and check the pressure, if it is weak, then you can call the housing office and find out what the problem is.

If the column does not ignite when water is supplied or turns on only at very high pressure, then the problem is most likely in the membrane, which, due to wear, does not respond well to the water passing through it. In this case, it must be replaced.

The geyser spontaneously turns off

A temperature sensor is installed on each geyser, which ensures that the geyser does not overheat in case of failure column may spontaneously turn off during operation. It usually looks like this:

After normal operation, for some time, the heater "stalls" for 20 minutes. After this time, it can be turned on for the same period of time. The malfunction, as a rule, is seasonal and appears only in summer or winter with the windows closed.

The device turns off when it wants to and then does not light up. This can happen when the sensor wire is shorted to the ground. Check the wires to make sure they are intact and well insulated.

In order to check the sensor itself for operability, you should remove two contacts from it and short-circuit it with a needle, a paper clip, or a piece of tin. If the gas appliance turns on and works, the sensor must be changed.

Water heater is leaking

If you see similar spots on your column, then be sure that it is leaking and needs repair.

This malfunction can occur mainly in geysers that have been operating for a long time. The two main reasons for leakage are:

Radiator leaked.

Cracked pipes (bends) or gaskets in the joints.
Replacing a radiator or taps is quite expensive. Therefore, there is a reason to repair the gas column on your own. For repair you need:

• screwdrivers (cross and regular);
• wrenches (set);
• solder with rosin;
• vacuum cleaner;
• solvent;
• "skin".

Hole sealing

Due to harsh working conditions, the radiator or taps can burn out and holes appear on them. If you have determined where the leak is, then you can repair a small hole with an ordinary soldering iron.

Preparing a geyser for repair

• Drain all liquid from the system - open only the hot water tap, unscrew the nut on the cold water inlet pipe, and most of the water will flow out;
• Remove the radiator completely;
• Examine the entire tube. - if you see "green" - clean and inspect these places for cracks.

When you find leaks, you need to do the following:

• clean the holes found with a “sandpaper” and immediately wipe with a cloth with a solvent (this will remove the remnants of fat, soot and dirt);
• using rosin with solder, tin this place with a 100-watt sanding iron (for lack of rosin, use aspirin);
• rub the crack or hole with solder, and after it cools, add more tin (the layer should be 1-2 mm).

Attention! In some cases, with holes of about 5 cm, the craftsmen apply a “temporary” overlay made of copper or aluminum plate, securing it with thick wire or metal tape. But as a rule, such a “temporary” solution remains for a long time. We recommend replacing the radiator completely and forget about its leaks.

Faulty gaskets and tubes

Replacing flexible hoses of this type does not require special skills, it can be done by anyone with a wrench.

Very often, leaks form at the points where the taps are connected to the heater from the outside or to the internal nodes of the dispenser. All connections are made by "American" with gaskets inside.

Due to constant heating/cooling, the rubberized liners either melt or lose their properties and harden. Cracks appear in them, through which water flows.
If you notice a gas column leak in such connections, then replace the gaskets. Using a wrench (mainly 24), unscrew the nut and replace.

It also happens that the flanges on the tubes crack over time - in this case, you need to replace the entire tube.

The geyser turns on with pops

Be sure to change the batteries in the gas column in time, because if they are dead, your column will start to make pops when turned on. Also, due to dead batteries, the column may spontaneously turn off.

These sounds when turned on and during operation indicate the following points:

• due to the low gas pressure, a little air got into the system (into the burner), which gave rise to a microexplosion;
• the flame breaks down due to the high pressure of the gas;
• jet blockage;
• small ventilation draft;
• the batteries have run out.

On your own, you can only eliminate the malfunctions described in the last two paragraphs.

The gas water heater does not heat the water well

This can happen for several reasons.

• The simplest reason is incorrectly selected gas column. You saved money and bought a low wattage heater unable to meet your hot water needs.
• The second reason is the low gas pressure in the pipes (in the apartment). Call the gasman to check the system.
• The third reason is the usual blockage (jet, filters, scale, hoses, etc.), some of which are described above. You can check this by the color of the fire, which changes from time to time. This is also evidenced by the presence of soot.

You can only adjust the temperature and clean the column yourself.

Remember! Self-adjusting the gas column and troubleshooting requires special care. With poor-quality work, not only you, but also completely innocent people can suffer. At the slightest lack of self-confidence, it is worth contacting the professionals of the gas service.
