Water heater - lifesaver for residents of apartments. Regardless of the time of year or the whims of communal services, you maintain a high level of comfort. For owners of private homes - this is the only way to get hot water. A wide range of speakers is not difficult to get confused. In this publication, we will talk in detail about the Demrad gas column - its features, as well as the most common problems.
What the brand Demrad offers
The products of the manufacturer "Demrad" are well known in 48 countries, including Russia. Although some users are probably the first to hear the name of the company. The Turkish company was founded in 1954. Initially, it was a factory for the manufacture of radiators and boilers. But today the company produces speakers, convectors, air conditioners.
Turkish geysers heat water for domestic needs in a flowing way. The technique is presented in three series:
- Demrad Compact range without chimney. Mechanical control with the help of regulators. Power reaches 10.4 kW. The unit is connected to the main and liquefied fuel. Coefficient of performance (COP) 84%. Includes protective sensors for flow, flame, traction, gas control.
- Chimney flow columns are also represented by Compact models. Their power is 24 kW. In general, the characteristics are similar to the first option.
- Turbocharged devices are equipped with a closed combustion chamber. Smoke is forced off by a fan. Ignition occurs automatically and due to the piezoelectric element. There is a system of protection against gas leakage, flame extinguishing, lack of traction, overheating.
The lineup is fully adapted for operation in Russian conditions. A modulated burner allows you to adjust the gas flow rate and maintain a constant temperature.

When I finally got tired of seasonal shutdowns of hot water, I decided to install a column. Since it was 6 years ago, there was not much choice. For its price and design, I liked the Turkish Demrad-C 150 S. The main thing is that it has a compact size, because I have a small kitchen.
Performance is enough to wash in the shower, wash the dishes. There are problems with the bathtub set, it takes a long time to wait. In general, for domestic needs an excellent option. I was thinking about buying more powerful equipment, but this one has been serving for 6 years without breakdowns - it's a pity to change. Moreover, it works for me constantly, I do not turn it off at night.
Regarding management. Initially set a comfortable temperature, the regulator is in the middle position. Therefore, I do not dilute the water, it immediately comes out warm. The torch is ignited with piezo ignition, which does not always work. The protective functions are excellent. If the wick goes out, the device automatically turns off.
Of the minuses: it does not start at low pressure, which often happens in the summer. Anyway, I recommend to buy, this is a time-tested technique.
Demrad C-350 F
The flow heater is designed for a capacity of 14 l / min. Power at heating 29 kW. It has a closed combustion chamber, connected to a coaxial chimney, which is displayed on the street through the wall. Combustion products are vented by a fan.
The burner is equipped with smooth electronic ignition and flame modulation. The column operates at a system pressure of 0.50–10 bar. Security system includes:
- Flame detector that fires when extinguished by turning off the appliance.
- Water flow control.
- Pressure sensor that works when the readings deviate from the norm.
- Thermosensor - captures the temperature in the circuit.
- Traction sensor - blocks operation in the absence of air flow.
- Gas control.

Demrad C-125 B
Chimneyless model with a turbocharged burner. The closed combustion unit is connected to a coaxial chimney. The outlet for the outlet pipe can be arranged anywhere, which is suitable for both apartments and private houses.
A productivity of 5 l / min is enough for showering or household needs. Power is 10.40 kW. When the main gas is turned off, the unit switches to fuel in cylinders. The launch is carried out using piezo ignition.
The device protects the fuse from overheating. There is also built-in protection against high pressure, running without water.

I bought Demrad C-125 B at the cottage. A great option for the summer, and performance is enough. He was engaged in the installation himself - no problems. The case is easily hung, the installation of the chimney is not required. For the winter I clean so that the equipment does not freeze and does not deteriorate. I noticed only one drawback when connecting - it is inconvenient to get to the terminals, they are near the back wall.
Failures of columns "Demrad"
Water heaters are also prone to breakdowns. The manufacturer equipped them with a self-diagnosis system. In the event of a breakdown, an error code is displayed. Its decoding is in the instructions. The value indicates the cause and location of the malfunction.
But not all problems are accompanied by errors. You may notice some during operation. We will tell you in which cases it is possible to carry out repairs, and in which - it is better to call the master.
Most often, users complain that the wick does not light in the Demrad technique. What's the matter:
- Ignitor is clogged. This happens when soot and dust accumulate. You can clean the element with fine-grained sandpaper. Turn off the gas valve before starting work. After cleaning, open the supply and check the ignition.
- Thermocouple does not work. This element consists of two types of metal and serves to start or stop the supply of fuel. If the thermocouple does not work and gas does not flow, then the wick does not light up. The item cannot be repaired; replacement is required.
- Traction problems. A draft is a stream of air that provides a stable flame in a burner. For ignition problems, check for traction. Light a match and bring to the control window or ventilation. With normal air flow, the flame will deviate to the side. If it burns smoothly, clean the chimney shaft. The coaxial pipe also needs to be cleaned. Condensation often accumulates inside.
- Filter clogging. Most speakers will not turn on without normal water pressure. A clogged inlet filter may obstruct the flow. Shut off the water supply, dismantle and rinse the filter. If the net is very clogged, leave it to soak in a solution of citric acid. Replace if worn.
- Diaphragm (membrane) problems. This element helps to open the gas valve. When the flow of water increases, it creates pressure on the membrane. It bends, the valve opens, fuel enters the burner. To check, remove the column cover. The membrane is part of the water block. If worn, deformed, install a new part.
- Solenoid valve malfunction. He is responsible for supplying fuel to the burner. If the valve does not open, repair or replace.
- Air supply problems. Strong draft contributes to quenching of the wick. In atmospheric devices, the lack of air circulation prevents fire. Provide good ventilation in the room.
- Traction sensor out of order. Call him a tester. Attach the probes to the sensor terminals. A working part will show infinity. In another case, connection of a working element is required.
- Batteries in electronic devices are dead. Open the unit (the cover is attached to the latches or screw). Take out the old batteries and put in new ones.
- Check if the gas valve is open.
- The microswitch or its rod is defective. Diagnose, if broken, replace.
Having appreciated the advantages and disadvantages of the heating equipment "Demrad", you will make the right choice. The equipment cannot last forever, but if it needs to be repaired and spare parts are easily found in your city, then this is another factor in favor of acquiring a model.
