The autonomous hot water supply system today is relevant not only for a summer residence or a country house, but also for a city apartment.
Interruptions in hot water and its summer shutdown, accidents and major repairs of networks deprive the already familiar comfort.
A flow-through water heater allows you to provide your home throughout the year with uninterrupted and high-quality hot water supply.
Rising electricity tariffs are tipping the scales in favor of gas-fired heaters as more economical.
Device
Column device (click to enlarge)
The gas column is a flow-through water heater, consisting of an ignition device, a gas burner, a heat exchanger, and a water-gas fittings.
All components of the device, together with the control and safety equipment, are enclosed in a compact and aesthetic housing. The ignition device ignites the main burner when the water tap is opened and the pressure in the system changes.
The gas burner ensures safe combustion of the gas by heating the water in the heat exchanger. When the water tap is closed, the gas flow is cut off and the main burner is automatically extinguished.
The ignition device can be piezoelectric or electric. At the push of a button, the piezoelectric element ignites the igniter, from which the main burner is subsequently ignited. In devices with an electric start, the spark source is energy from electric batteries.
Vega max
This modification is designed to replace the models 5502, 5505, 370, 371. All four versions have already been discontinued several years ago, but instead of them, as the previously installed equipment wears out, a new column can be installed without changing the connecting dimensions. Thanks to this, updating water heaters will be easy and simple. The geyser is wall-mounted, capable of developing a thermal power of 17.3 kW, providing up to 10 liters of heated water in 60 seconds. The following are used in the construction of this model:
- German fittings for water and gas Mertik;
- main and pilot burners, Czech-made heat exchanger;
- pipes with a wall of 0.1 cm.
The system automatically maintains the preset fluid temperature. There are two options - with piezoelectric ignition and with battery power. The entire range of safety devices has been installed.
The transfer of the gas valve to the open position is excluded when the water supply is turned off. Gaseous products will definitely not get out.
Instantaneous water heater
Mora Top geysers are assembled at their own production in the Czech Republic. These are reliable and high-tech units for the installation of a hot water supply system for an apartment or cottage.
Water heaters are characterized by high efficiency, the efficiency is 92%. Their operation is practically silent, which allows them to be installed anywhere. The fuel for them can be both natural and liquefied gas.
The mora speaker line consists of the following models:
- VEGA 10 (versions 10 E, 10 MAX, 10E MAX) - power 17.3 kW, water consumption 5 - 10 l / min. The series is produced as a more modern replacement for models 370, 371, 5502, 5505.
- VEGA 13 (variant 13 E) - power 22.6 kW, water consumption 6 - 13 l / min.
- VEGA 16 (version 16 E) - power 26.4 kW, water consumption 8 - 15.2 l / min.
The capacity of these water heaters is sufficient for the simultaneous operation of 1 - 3 water-folding devices. All models are available in compact wall-mounted enclosures. The difference in the variants of the models lies in the presence of electric ignition from the built-in batteries, letter "E" in the marking.
Possible malfunctions and ways to eliminate them
It is better to immediately contact the services of a service center if the warranty period has not yet expired. Representatives of the company from the Czech Republic work in almost all major cities. There are several problems that users encounter most often:
- The water does not heat up well. Most often this is due to incorrect settings. You need to look for special recommendations and tables. Usually the manufacturers themselves give the appropriate advice.
- The wick goes out when the heater is working normally.
A common cause is not enough traction. The condition of the chimney ducts is checked, first of all. The water heater is accurately installed with irregularities, if the pipe is clean, but the draft sensor still works. This means that there is not enough oxygen in the boiler room for normal operation. The problem can be solved by installing a supply and exhaust valve. The main thing is not to choose bad cheap counterparts.
- There is a leak.
Most likely, the rubber membrane at the water reducer has torn. Corrosion eats away at the heat exchanger. It is recommended to install copper coils in the place of leaks.
- The main burner does not start. Sometimes Torah models also suffer from this.
This usually happens when the batteries are low. Or due to poor water pressure, lack of oxygen inside the room in sufficient volumes.
Note!
A breakdown of the water unit reducer is also a common breakdown. There are rubber gaskets inside the block, which quickly break due to the pressure of water. On average, the membrane needs to be changed every 5-8 years.
Service centers, official stores are the best places to purchase spare parts for gas water heaters. Then there is no doubt about the quality of consumables.

The Czech company Mora Top has been present on the gas water heater market for many decades. All this time, she tries to produce flawless products that satisfy all the needs of consumers. At the same time, the company does not lag behind the requirements of technical progress. Consider the most popular models of geysers of this brand, their features, and also give valuable advice on operation.
Features of the
Instantaneous water heaters of the Vega series have a number of unique properties that have won the sympathy of buyers for these devices:
- All water heaters of the Vega series use fittings from the German company Mertik, which include a column at a flow rate of 2.5 l / min.
- Automatic maintenance of temperature when changing water consumption.
- The design of the heat exchanger provides a heating rate 15% higher than analogs.
- The diameter of the tubes is 18mm and special turbulators on their inner surfaces prevent scale settling.
- Diameter of the gas duct neck from 115 mm.
- The heat exchanger is protected by a water temperature limiter that prevents overheating.
- Backdraft fuse, prevents combustion products from entering the building. This allows you to install the water heater in any room.
- The flame fuse monitors the burners.
- Dry-start fuse - the burner will not ignite without water.
The price of Mora top gas water heaters does not exceed analogues, the same Hayes. Market value from 16 thousand rubles. Compared to analogs of Mora, they have higher consumer properties.
Model Vega 10
This is another promising model from a Czech firm. Its characteristic advantages are, in addition to its brilliant design, compact dimensions and technological excellence. The nominal thermal generation is 17.3 kW, and the spread in the amount of water produced (when heated to 25 degrees) is from 5 to 10 liters. The device is capable of operating in an automated mode and consumes 10% less gas than other products of comparable power. Efficiency up to 92%, as well as smooth power control, also cause positive feedback from customers.
Combined fittings from Germany are able to turn on the column even at a pressure of 2.5 liters in 1 minute. Other constructions of the same kind do not provide this possibility. Importantly, the German developers also made sure that the strictly set temperature was maintained. This allows you to extinguish the negative effect associated with pressure surges. The refusal of moving parts to work in water prevents the drawback of most columns - a high risk of leakage at the intersection of the water and gas fittings.
Installation of instantaneous water heater
Before installing the column, you need to decide on the room and place of installation. The room must have ventilation, and the wall must be made of non-combustible material.... Installing a column is usually straightforward and consists of the following steps:
- fixing the device to the wall. Standard brackets from the delivery set are used. Pay attention to the strength of the wall and its flammability;
- supply of pipes for cold and hot water. It is advisable to install shut-off valves before the inlet pipes;
- chimney connection. The chimney is connected with pipes with a diameter not less than the outlet of the device. The chimney material must be resistant to combustion products and high temperatures, its length must be minimal;
- connection of main gas. It is better to entrust this procedure to the professionals involved in the installation and operation of gas equipment.
The water part of the gas column: basic malfunctions
Often, problems with the operation of the column relate to malfunctions in the gas-water unit system.In order, if necessary, to be able to troubleshoot on your own, you need to know how the water part of the column works.
So, the gas-water column block consists of:
- Membrane and disc;
- Water temperature regulator;
- Water supply regulator with open and closed mixer;
- Venturi nozzle;
- Strainer at the inlet to the unit.
Malfunctions in the unit can arise both under the influence of external factors (for example, due to damage to the speaker case, power cable), and due to wear and tear of equipment. Most often, the incorrect operation of water heating gas equipment is associated with the low quality of tap water, low water and gas pressure, and clogged ventilation pipes.
The most common internal breakdowns of Mohr's gas columns are:
- Clogged inlet water filter of the water intake unit;
- Deformation or clogging of the membrane of the gas-water unit;
- Blockages in the heat exchanger pipes.
In addition, often, the reason for the incorrect operation of the electric column is the discharge of the supply elements (batteries).
A little about the company
MORA-TOP began its 185-year history as a subsidiary of MORA MORAVIA AS. And only in 2003 it became independent. In the spring of the following year, the construction of a plant began in the Czech town of Unicov. The capacity took 5,000 "squares" and was built in less than a year, so that in the spring of 2005 the world saw the first Mora instantaneous gas water heater, produced at the new factory.
Today, the company has a fully established technological chain of manufacturing equipment, including:
- Technology for processing copper and manufacturing heat exchangers, as well as stamping, degreasing, soldering and painting.
- Manufacture of thermoelements of construction.
- Assembly of finished products within the assembly line.
- Mandatory testing of devices.
Reviews of the speaker model MORA-TOP Sirius PK20KK
Mora Tor is a gas water heater that has excellent functionality and unique features. Consumers highlight the power-on indicator, flame modulation, auto-ignition and thermometer. All this makes the operation convenient and simple. As features, it is worth highlighting the possibility of connecting external control, the presence of a display, as well as connecting a warm floor.
As buyers emphasize, the column is very durable, because the maximum water pressure in the heating circuit can reach 3 bar, while in the hot water supply circuit this figure can be 6 bar. Hot water performance is also very popular with customers. At a temperature of 35 ° C, this parameter will be 8.4 liters per minute. If the temperature is lowered to 30 ° C, in one minute you can get 9.8 liters. At 25 ° C, productivity will increase to 11.8 liters per minute.
The Mora top gas water heater consumes 2.39 m 3 of natural gas per hour. Natural gas has a nominal pressure of 13 mbar. Consumers quite often write reviews about this model, after reading which, you can find out that the kit has a built-in expansion tank, the volume of which is 7 liters.
