Gas boilers from Protherm

Protherm was founded in 1991 in Slovakia.

Today it is part of the same holding with the recognized flagship - Vaillant, which allows us to confidently talk about powerful technological and consulting support... This condition has a positive effect on products - with an average price range designed for a mass buyer, the quality of equipment is not inferior to other representatives of this direction.

Gas boilers are one of the types of heating equipment manufactured by Protherm for export. All units are being adapted to the technological conditions of the area where they will be operated.

They are able to withstand fluctuations in power supply, operate at low pressures of water and gas.

Combined boilers Protherm - Proterm

Views

Protherm gas boilers are available in different design and model options and can be divided into several groups that have certain characteristics.

For example, according to the type of installation, boilers are:

• Wall (hinged).
• Outdoor.

By the number of contours:

• Single-circuit (produce only heating of the coolant for the heating system).
• Double-circuit (provide the room with hot water in parallel with the preparation of the heat carrier).

In addition, they differ in the way they are heated.:

• Convection. Heat transfer takes place only in a heat exchanger heated by the flame of a gas burner.
• Condensing. Preheating is carried out in a condensation chamber, where the precipitation of water vapor from the extracted smoke and exhaust gases is carried out.

By type of combustion chamber:

• Atmospheric or open. Combustion and smoke extraction are carried out by natural draft.
• Turbocharged or closed. For the process to proceed correctly, a fan is used to supply air to the burner and ensure that the smoke is removed.

NOTE!

Such an abundance of options creates an extremely rich assortment, allowing you to choose the right sample for any conditions and needs.

Floor series

The most popular option is "Bear". The heater itself and the heat exchanger are made of cast iron.A chimney draft monitoring system has been installed. If the thrust is lost, the burner goes out. All models have two circuits. There is an electric ignition and a smooth power control. You can connect a fan - to forcibly remove the combustion products.

All floor-standing versions of Protherm have an open hearth. There are "Bears" marked:

• PLO - piezo ignition. Two stage burner.
• KLZ - similar to the previous one, but with a 110 liter boiler.
• TLO are non-volatile. Atmospheric burner.

"Bison" and "Beaver" are also floor versions. They can operate on gas, solid and liquid fuels, therefore they have a large combustion chamber volume. All floor-standing modifications are capable of operating as part of a cascade. The cascade scheme involves the installation of boilers in a certain sequence - in order to increase the total power. It happens that one device is not enough to heat a large cottage, then a second one is added to it - with the same or less power.

Series

Protherm products are divided into series and model lines, which are united by a common name and design features.

For simplicity, the series are named after animals - for example, wall-mounted cauldrons belong to the "cat" group and consist of the following series:

• Jaguar. Basic, low-cost, convection-action two-circuit model with a power range from 11 to 24 kW.
• Lynx. Convection, later - a condensing apparatus with two circuits. Available in 11, 24 and 28 kW models.
• Panther. consists of 4 models with a capacity of 12, 25, 30 and 35 kW. There are single and double-circuit versions with atmospheric and turbocharged burners.
• Cheetah. Two models with a capacity of 12 and 23 kW. Compact and budget units with record low noise level.
• Leopard. The entire series is represented by one 24 kW dual-circuit model.
• Tiger... One of the most recent models. Combined with a built-in storage boiler. Power 12 and 24 kW.

Floor standing boilers:

• Wolf. Non-volatile single-circuit boiler that does not need to be connected to the network. one of the cheapest and most reliable models.
• Bear. A series of several lines with different design features, among which there is a piezo ignition of the burner, the presence of one or two circuits, etc. Model power from 17 to 49 kW.
• Grizzly. A series of devices with increased power from 65 to 150 kW. They are used in large residential buildings, can be installed in shops or public buildings.
• Buffalo... A series of universal floor-standing boilers capable of operating both on gas and on fuel oil or diesel fuel. can be assembled in a cascade with a high power of industrial value.

The series and model lines of Protherm boilers are constantly expanding, new devices are being developed and existing devices are being improved.

Technologies are moving forward, allowing to create more advanced models of heating equipment.

Wall series

The most popular option among apartment owners. They are economical and compact and can be installed directly in the kitchen. The Protherm wall-mounted boiler has the following features:

• Frost protection.
• The power is infinitely variable - 3,500-11,000 kW and 9,500-23,000 kW.
• The circulation pump is protected against seizure.
• The control unit has a display showing the current information about the work. There is a microprocessor.
• Self-diagnosis function.
• Overheating protection.
• Separate power control for heating and DHW.
• Built-in boiler for 25 liters.
• Electronic system SPIN - to monitor the temperature and rate of heating water.

Specifications

General specifications are easier to study in the form of a table:

Error codes and how to fix them

Thanks to the self-diagnosis function, modern boilers themselves determine malfunctions, and information in the form of digital or alphanumeric codes is displayed on an electronic display. Having understood what is hidden under this or that code, you can from the table posted in the installation and operating instructions.

An example of an electronic display of a Panther boiler with three digital blocks. The two lower digital displays show error codes for heating and hot water systems

The Proterm brand produces many modifications under different series, and the error codes for different models may not coincide. To clarify the meaning, be sure to study the documentation for your unit.

Consider the errors of gas boilers "Proterm", which are most common in popular models.

Models "Jaguar 11" and "Jaguar 24"

The main problems faced by users relate to either sensor breakdowns, or changes in performance indicators to critical ones. Consider the errors of the Proterm Jaguar gas boiler, represented by two popular models with a capacity of 11 kW and 24 kW.

For example, when the coolant overheats to + 98 ° C, the boiler stops its operation, and an error is displayed on the display F01.

Functioning often improves when the temperature returns to acceptable operating parameters. To resume activity, you need to restart the boiler by pressing the "reset" or "start" button

Ignition often does not take place, and when trying to ignite the flame again, an error appears F04... There can be two reasons: breakage of the ionization electrode or interruption of gas supply.

The easiest way is to check if the gas cock is open. If everything is fine with the fuel supply, the point is in the ionization system, which not everyone can repair on their own. The manufacturer recommends contacting the service center.

A blocked chimney of a gas boiler is signaled by a code F05... If the air supply is restored, the unit will continue to operate. The same error indicates changes in voltage: if it falls below 165 V, the boiler stops working until the operating parameters stabilize.

Codes F02, F03, F09 notify about malfunction of various sensors.

If, when the hot water sensor breaks down, the device is still working, then the failure of the remaining sensors will stop its functioning.

Replacing elements requires skill and experience - and if you do not have them, we recommend contacting a service center.

An error appears quite often on the display F10associated with pressure. One of the reasons is the breakdown of the pressure sensor, the replacement of which is better to entrust to gas workers with whom a contract for service and gas supply has been concluded. But if the matter is in changing the pressure parameters, the situation can be corrected independently.

The working pressure range is 1-2 bar. If the value falls below 0.3 bar or rises above 2.7 bar, the unit stops. To return it to work, you need to return the operating parameters.

How it's done:

• find the make-up valve in the lower part of the boiler, near the contour pipes;
• turn it counterclockwise until the pressure returns to normal;
• close the valve by turning it clockwise - when not closed, the pressure will continue to rise.

It is better to aim for the 1.5 bar indicator - the positive results of the actions will immediately be reflected on the display. If you overdo it and raise the pressure to 2.5 bar, the boiler will stop working again. During make-up, you must not block the branch pipes to which the DHW and heating pipes are connected.

Floor-standing boiler "Bear"

Most of the malfunctions of the "Bear" gas boiler are eliminated in two ways:

• automatically, after elimination of the cause (for example, F.10 - short circuit of the temperature sensor in the water supply circuit, F.73 - short circuit on the body or disconnection of the hydraulic pressure switch, etc.);
• by pressing the fault clearing button located on the control panel (for example, F.20 - signal from the temperature limiter, F.28 - lack of ignition at the 1st start, etc.).

Some breakdowns or malfunctions can be adjusted / repaired manually without contacting the representatives of the gas supply and service company.

If the boiler refuses to turn on and work, does not heat the water, there are many reasons for this "behavior".

Perhaps the gas tap is simply closed or the power supply is turned off - then it is enough to turn the handle of the tap or resume the power supply, and then repeat the ignition procedure

Sometimes the boiler “protests” due to incorrect temperature settings - it is necessary to adjust the flow temperature, as well as the hot water temperature. If there is not enough pressure, you need to add water, and if there are air locks, release air from the radiators.

The situation changes if one of the functions remains in effect and the other fails. For example, the unit heats water in the DHW circuit, but refuses to heat the house. Most likely, the program settings have gone astray and the boiler "thinks" that the room is already warm enough. It is necessary to adjust the calculated temperature value in the house, and the heating circuit will start.

If, on the contrary, the heating is normal and cold water flows from the hot water tap, it is necessary to increase the temperature of the hot water.

One of the most alarming signals is water under or near the unit. This indicates a violation of the tightness. Most likely, you cannot cope on your own, and specialists will be required to solve the problem

If the boiler turns off unexpectedly and the display shows the code F.20, the manufacturer recommends unlocking the high limit safety cut-out.

Procedure:

• Wait for the unit to cool down.
• Using the device diagram, remove the front casing from the body.
• Find the fuse under the junction box.
• Turn and remove the cap.
• Press in the pin as deeply as possible.
• Press the fault clearing key.
• After making sure that the boiler is working, replace the front panel.

If the problem recurs regularly, it is better to contact the service.

Wall-mounted boiler "Cheetah"

Error codes and recommendations for correcting them are similar for all Proterm wall-mounted boilers, but there are slight differences, since the technical characteristics also differ.

For example, the operating pressure range is from 0.8 bar to 2 bar, therefore, only after the reading drops below 0.8 bar, the unit will generate an error. To make the device work again, you need to add water to the heating system.

How to fill the heating system:

1. Open the thermostatic valves.
2. Open the filling device.
3. Slowly pour in water until the network pressure reaches the operating parameters.
4. Remove air from radiators.
5. Close the filling device.

During the procedure, do not forget to monitor the changes in pressure values ​​on the display.

The maximum threshold upon reaching which the boiler stops is 2.8 bar. If this happens, the pressure must be reduced by draining the water through the safety valve.

One of the most common mistakes is the failure of the gas pressure regulating valve (error F.28-29), so we will analyze how to fix the Proterm gas valve on our own.

Disconnect the inlet gas supply and power supply. Then remove the front metal panel, find the gas valve for repair and carefully unscrew it.

The gas valve is a complex part, consisting of several small parts - some of them can be removed for cleaning or replacement

If the valve is simply clogged with poor quality fuel, you need to disassemble it and wipe all the elements, being careful. If the blockage is due to wear and tear of parts, the valve must be replaced. Most often, plastic elements break, which can be simply changed.

The reason may also be hidden not in the valve itself, but in the power supply system - you need to check all the contacts and make sure that the power supply is stable.

To correct the errors of the Proterm Gepard gas boiler, you need to refer to the technical documentation, which contains the manufacturer's advice. If the sensors of the gas boiler and other elements fail, they must be replaced.

If you are unable to replace the temperature sensors, electronic board, fittings on your own, it is better to contact the service center. While the unit is under warranty, you also cannot repair yourself.

• F10 / F11 - short circuit in the system of temperature sensors at the supply and return of the coolant.
• F13 - DHW temperature sensor is faulty.
• F20 - overheating in the heating circuit. There is no circulation, the circulation pump is faulty.
• F22 - lack of coolant in the system.
• F23 - a high temperature difference in the supply and return of the coolant in the heating network, it will be necessary to adjust the gas boiler and check the temperature sensor.
• F24 - leakage in the heating circuit.
• F25 there is no vacuum in the furnace, the chimney is clogged, a draft sensor must be installed.
• F26 - there is no voltage in the stepper motor valve system, boiler adjustment is required.
• F27 - failure in the flame control system in the combustion chamber, a check of the control unit will be required.
• F28 - there is no flame on the burner during the boiler firing up.

What kind of premises is it suitable for?

The vast majority of Protherm devices are designed to work in private homes or similar premises (public, office, retail).

It is possible to select the most successful modification, providing only heating of the heating system, or also performing DHW preparation.

When choosing the best option, one should be guided by functional indicators, as well as monitor the correspondence of the power and area of ​​the room.

Major malfunctions

All possible malfunctions are immediately detected by the sensor system and displayed as an alphanumeric code.

Aggregate errors
arise for various reasons, among which are:

• Open or short circuit of a sensor.
• Lack of flame.
• Lack of water.
• Stopping the smoke output.
• Failure of the circulation pump.
• Fan stop, etc.

Most errors cause immediate shutdown of the boiler for safety reasons. Situations are possible when there is no one in the house, there is no one to respond promptly to the appearance of signals.

NOTE!

Therefore, the security system produces an emergency lock, which is reset by the owner upon restart. A complete list of error codes is available in the user manual.

It is a rather lengthy list, and there is no point in listing it entirely.

Owner reviews

We find out what the owners themselves, who are not interested in promoting or creating anti-advertising for boilers, say about Protherm gas units:

No recall found! Please insert a valid revocation ID

Complaints about the poor organization of service are heard from everywhere, from the first days of the start of deliveries. Protherm should have been worrying about the state of the repair service for a long time, since the demand and popularity of boilers depends on it.... So far, reviews on the quality of the technicians' work are extremely negative.

Testimonials

• Andrey G.“I have built a house, winter is on the way, we need to heat it with something. I wandered on the Internet, read reviews, and decided to buy a boiler from the Slovak company Proterm. I chose the wall option based on the area of ​​the house. The boiler with the beautiful name Cheetah Model 23 MTV came up best. What can I say? It is very simple to operate with three buttons. The instruction is very intelligible and explains everything in detail. It makes a little noise, but does not interfere with falling asleep. Very compact. Maintenance is very simple - it is enough to occasionally clean the dirt filter and wipe the dust from the boiler. It performs its functions without problems. I did not notice any shortcomings. I recommend".
• Vasily V. “I decided to change my old gas water heater. And since in extreme frosts the heat from the stove is often not enough, I decided to install a modern gas boiler with the ability to heat water. The choice was determined only by price. I took an inexpensive Jaguar 11 JTV from Proterm. The boiler turned out to be surprisingly quiet, with a beautiful design. For 2 years I have never broken. There are no shortcomings. "
• Vladimir U. “I have been working for 11 years in a service center for the maintenance of heating boilers, including gas boilers. During this time, I had to install and repair all types of boilers of all firms that are sold in our stores. I can't say anything bad about Proterm gas boilers. With proper installation and proper setup, they work like a clock. But if the service specialists have neither the skills nor the experience, or the owners have adjusted something on their own, then problems in their work are inevitable and, as a result, bad reviews.
