The structure and internal design of Czech gas boilers Mora Top made it possible to create a new generation of heating equipment that optimally complies with European and domestic standards.

The Mora manufacturer's line includes mounted and floor-mounted units, differing in different technical characteristics, operating principles and performance.

Review of Mora floor standing boilers

Mora Top floor-standing gas heating boilers are presented in more than ten modifications, the main difference of which is the type of burner and combustion chamber used.
To increase performance and heat transfer, it is recommended to use antifreeze. The heat exchanger and internal structure are designed taking into account the use of this liquid as a coolant.

As practice shows, the Czech water-heating energy-independent floor-mounted instantaneous gas heating boiler Mora Top is the optimal solution for heating country houses. The absence of complex automation, electricity-dependent components, high productivity - all this distinguishes the equipment of this series.

Carrying out installation work

Mora gas appliances are designed in such a way that installation and maintenance of boilers are as simple and easy as possible.
All volatile models have a self-diagnosis function. Information about all violations is displayed on the LCD display. The boilers are equipped with Mora equipment. As a result, automation, burner and other components ensure stable and long-term operation. Commissioning and adjustment of the boiler is carried out as follows:

• Volatile boilers are connected to the network. The self-diagnosis function starts automatically. The controller checks the presence of pressure in the heating system and gas pipeline. When deviations are found, a signal is issued in the form of a digital value. After troubleshooting, the boiler starts up.
• Non-volatile units do not have self-diagnosis functions, automatic flame ignition, etc. Therefore, before starting up and putting the equipment into operation, the company representative must ensure that all installation recommendations are followed. It is mandatory to install a water treatment system and a safety group; you may need to connect an expansion tank and a circulation pump.

Czech Mora gas boilers generally start up without any difficulties, but there are exceptions, mainly related to transportation or installation problems.

One of the common malfunctions of a double-circuit boiler is the failure of the thermocouple. After replacement, the functionality of the equipment is fully restored.

Why you should buy a Mora boiler

Mora's boilers have something that other manufacturers often miss - an understanding of the complexities and peculiarities of working in domestic conditions.
A potential buyer is also attracted by the possibility of choosing a suitable model. A huge range of models is presented: from 15 to 750 kW. You can choose a fully automatic installation and a classic boiler without complex automation. Simple operating rules also ensure the popularity of Czech Mora models.

The company Mora Top sro acquired characteristics close to its modern form in 2000 as a subsidiary of a joint stock company with a similar name - Mora Moravia. But at the beginning of the last century, one of the boilers of the above-mentioned enterprise was manufactured in the amount of hundreds of thousands of units per year. By the way, it was the Meteor boiler that became the first heating equipment in the world, the manufacture of which took place abroad under a license agreement. In 1924, the Soviet government decided to produce this type of boiler in St. Petersburg (then Petrograd).

In 2003 it gained independence, which was strengthened in 2004 with the start of construction of a new plant. In the spring of 2006, the production and technical base of the Mora Top enterprise acquired the shape of today. But the plans of the company’s management include the commissioning of additional production lines, which will lead to an increase in the number of products produced by more than three times. However, already now the plant’s production capacity allows it to produce about one hundred thousand water heaters and about fifty thousand gas boilers per year.

The quantity of products and their quality indicators determine the fact that Mora Top heating equipment is distributed not only in the Czech Republic, but is also exported to Romania, Bulgaria, Poland, Slovakia and the countries that once made up the Soviet Union.

The product range of the enterprise consists of the following categories: gas wall-mounted boilers - Titan (can be equipped with additional equipment, has an operating power of 14.8 kW, is immune to power surges, equipped with safety systems that ensure complete operational safety); electric boilers - Electra 8 (smart electric boiler, which is controlled by a microprocessor panel and can operate in more than ten functional modes; power from 2.5 to 7.5 kW); indirectly heated storage water heaters - 100 NTR (they are a water heating addition to heating boilers); combined storage water heaters - E 100 NTR (in addition to the ability to receive hot water from the energy of a heating boiler, they can heat it using a built-in electric element); wall-mounted instantaneous gas water heaters - Vega (very compact, available with power from 17.3 to 26.4 kW); floor-standing gas boilers with atmospheric burner - SA 20–60 (Classic series, fourteen different types with power from 15 to 50 kW); floor-standing boilers with forced-air burner - VL100 - VL750 (sixteen types with power from 103 to 750 kW).

Modern gas boilers are quite complex technological equipment. With proper care and proper handling, the gas boiler will serve for a long time without any failures. However, even the most expensive and functional equipment has its resource, after which various types of malfunctions begin to appear.

Knowing the main causes of problems and the procedure for eliminating them, you will be able to repair your gas boiler yourself. This is a very painstaking, responsible, but in most cases relatively uncomplicated work.

First of all, it is necessary to establish why any malfunctions may occur in the operation of gas heating boilers. A number of different factors can lead to problems.

Electricity

Modern gas boilers are equipped with various automation equipment. These products, in turn, are powered by electricity. And, despite the fact that it is already the 21st century and systems for the use of alternative energy sources are being actively developed all over the world, the problem of the stability of power grids remains relevant for many regions, especially for remote villages and all kinds of holiday villages.

A sudden shutdown or a strong surge in electricity is one of the main enemies of any modern gas boiler.

To avoid all the associated troubles, buy a high-quality stabilizer in advance. Do not spare money to purchase this device - cheap models are of little use, so it is better to immediately allocate funds to purchase a good stabilizer from a well-known manufacturer. Rest assured, if the automation breaks down, you will spend much more money on its repair and replacement.

Water

At home, wall-mounted models of gas boilers are often used. Such devices are simultaneously responsible for heating the premises and preparing hot water.

The design of wall-mounted boilers includes a flow-through heat exchanger. Low-quality hard water with various inclusions is the main enemy of the gas boiler heat exchanger. Moreover, under the influence of low-quality water, the heat exchanger can fail in just one season.

To prevent such damage, install special filters. The best option is a complete water purification system. With it, your boiler will work for as long as possible, and using purified water is much safer for your health.

Installation errors

Any knowledgeable person will tell you: the installation and piping of gas heating equipment should be carried out exclusively by qualified specialists.

Even the slightest errors at the stages of installation and connection of equipment can lead to irreversible consequences. For example, incorrectly performed piping in the case of a cast-iron gas boiler with a power of more than 50 kW will lead to the fact that the unit will simply crack at low temperatures.

Therefore, if you are not an experienced gas installer, entrust the installation of the boiler to professionals - this way you will save yourself from many problems in the future.

Weather

Adverse atmospheric conditions can also lead to many different problems. During frosty winters, people turn on the heating at almost full power. This leads to a significant decrease in pressure in the gas pipeline system. As a result, boilers cannot reach their full potential.

You won’t be able to solve this problem on your own - you still won’t be able to explain to your neighbors that their actions are only aggravating the situation. As a solution to the problem, you can install an additional boiler that runs on a different fuel.

Is it worth repairing the boiler yourself?

A modern gas boiler is a complex and potentially dangerous system. The main danger of such units is the risk of a gas explosion in case of improper handling of the equipment or untimely elimination of various problems.

Various types of automation are responsible for maintaining the operation of the gas boiler at an optimal level. An inexperienced user is often unable to understand its structure. Therefore, to resolve serious problems, it is better to immediately invite specialists.

On your own, you can try to eliminate only visible damage and various contaminants that have led to the failure of the pipe, chimney and other parts of the boiler.

There are a number of typical problems that, in most cases, you can fix yourself. Problems will also be listed, in the event of which you can only protect yourself until a specialist arrives.

If there is a distinct smell of gas or smoke in the room, immediately turn off the boiler and leave the room, opening it for ventilation.

Call a specialist immediately. Trying to solve a gas leak problem on your own without the necessary skills is extremely dangerous and unwise.

Flame sensor failure

If the combustion sensor or gas supply pipe is broken, turn off the boiler, close all gas valves and allow the unit to cool completely.

After some time, return to the room to check for the smell of gas. If everything is fine with the draft, try turning the boiler on again. If there is no traction, immediately call a repairman.

Boiler overheating

Overheating is one of the most common problems with modern gas boilers. The reason for this may be a malfunction of automation equipment or a clogged heat exchanger.

Automation repairs cannot be handled without the appropriate knowledge.

You can clean the heat exchanger yourself. The most common materials for the manufacture of heat exchangers are copper and stainless steel. Cleaning them usually isn't a problem, but still be careful.

To clean the heat exchanger, simply remove it and thoroughly clean it with a wire brush. In the case of a copper heat exchanger, it is better to replace the brush with a metal sponge used for washing dishes.

Charge fan malfunctions

The problem with fans is their bearings. If your boiler fan stops developing the set number of revolutions, try to fix the problem as soon as possible.

To do this, remove the back of the fan, remove the stator and lubricate the bearings. Machine oil is perfect for lubrication, but if possible it is better to use a higher quality carbon composition with heat-resistant properties for this purpose.

An interturn short circuit can also cause problems with the fan. Only a specialist can cope with troubleshooting this problem. Submit the stator for repair to replace the winding, or immediately replace the faulty unit with a new device.

Chimney problems

Often, various problems in the operation of a gas heating boiler are caused by excessive clogging of the coaxial chimney.

Remove the chimney and thoroughly clean all its components of soot. This way you will not only return the previous level of efficiency of the unit, but also significantly increase the efficiency of the boiler.
