Boiler overview
If you decide to purchase gas boiler equipment from, then you must be prepared for the fact that all models of this supplier are floor standing. Their dimensions are quite large, and the outer casing has a protective enamel. Additional characteristics include 3-mm steel at the base of the case, as well as the ability of the equipment to maintain the desired temperature regime.
The efficiency of the units reaches 90%. They are non-volatile and presented for sale in several modifications. Some models have the ability to prepare hot water for consumption. The units can be of thermohydraulic type automation or SIT system. The first option deals with non-volatile devices. The shutdown and fuel supply is controlled by a thermostat. When the temperature near the device reaches a certain parameter, gas stops flowing to the main burner, this allows you to maintain the required temperature regime.
Gas boilers "Conord", reviews of which you can read in the article, are well adapted for operation in conditions of not only severe, but also warm winter. They maintain the set temperature with the correct power calculation. The burner is installed with good quality, due to which good productivity is achieved, an optimal gas-air mixture is created and thermal insulation is provided. Due to these features, the gross volume of heat is spent on heating water.
Security systems
Floor standing gas boilers "Conord" are safe and have several systems responsible for this. Among others, a smoke exhaust sensor should be highlighted, which is triggered in the absence of draft, it turns off the gas supply to the burner, as well as if a short-term reverse draft occurs. Such conditions can occur with intense gusts of wind.
The flame on the burner is constantly monitored. If not, then the gas supply is suspended. The temperature in the heating circuit is monitored. Heating of the coolant stops when the temperature reaches a certain value. The described devices function perfectly even at low fuel pressure.
Operation of the gas boiler "Conord"
On the Internet, you can find many reviews about the acceptable cost and reliability of the Conord gas boiler. But you can also see negative reviews, which are most often associated with the extinction of the boiler for no reason. This problem can arise for several reasons:
- There is not enough air for normal operation of the pilot burner. In order to fix this, it is necessary to clean the air supply nozzles, and also check the ventilation in the room;
- Burner dirty. In this case, the air and gas nozzle must be cleaned. This can be done with a brush or vacuum cleaner;
- Defective flame sensor or draft sensor;
- The thermostat contacts have oxidized. With such a problem, you should stir or clean the contacts;
- Most problems can be fixed on your own, while in other cases you will have to use the help of a specialist.
The temperature of the heat carrier in the system may drop significantly. To eliminate this problem, turn the thermostat switch to the maximum position, and then increase the gas flow to the burner. This can be done if it is indicated in the instructions for the gas boiler.
During the summer period, it is necessary to perform some actions for the boiler to work. To turn off the heating circuit, turn off the tap on the water supply.When the pilot burner is operating, the water will heat up to 60 degrees within 1 hour. After the boiler has warmed up, it can be turned off if an active flow of warm water is not needed. Otherwise, the water may boil and the boiler will be damaged.
Overview of marking and its decoding
You can find out about some technical characteristics of the boiler if you pay attention to the marking. It may look as follows: KSC-G-10S or KSC-GV-12. The letter "K" stands for "boiler". The fact that it is made of steel is indicated by the letter "C". If the design of the firebox is cylindrical, then you can find out about it by the letter "C".
Gas boiler equipment is designated by the supplier with the letter "G". If in front of you is a boiler that provides the function of hot water supply, then you can find out about this by two letters - "GV". After the letter designation, you will see numbers. They indicate the maximum power level.
In order to determine the required power when buying a boiler, the area of the room is taken into account. For every 10 m2, 1 kW of power will be needed. This is true if the ceiling height is 2.5 m. It is important to take into account that this choice is relevant for an average level of heat loss.
