Retail chain stores offer large number of gas water heaters. Generally they flowing type, i.e. traditional geysers. They have simple design which is known to trifles long ago: blowpipe which provides heating of the water passing through the heat exchanger, and the control unit (automatic equipment). When choosing it is necessary to pay attention to parameters and functions of the last as safety depends on it.
Instruction
1. Stop the choice on the flowing gas heater with automatic start of heating of flowing water at the time of opening of tapping cock. It differs from old columns of the Soviet sample radically. As a last resort choose the device where it is necessary only for turning on of the water heater to press piezo or electroignition.
2. Turn when choosing the gas heater on safety automatic equipment. The device has to be protected from interruptions in giving both water, and gas. In any of these cases, automatic equipment has to disconnect independently. Also let there will be protection of the gas water heater against overheating. Besides, the device has to have system against carbon monoxide poisoning. To reduce risk in this question, put the sensor of lack of draft. At emergence emergency the situation, automatic equipment of the water heater has to switch off the device.
3. Define what system of removal of products of burning of gas from the water heater suits you on the project of the apartment - with the closed or open combustion chamber. The last - classical flues when carbon monoxide goes beyond the account of natural draft. This design is simple and has small cost. But, there are both difficulties when mounting and obtaining permission to arrangement of flue. The gas water heaters having the closed combustion chamber i.e. bezdymokhodny, are more expensive. They carry out conclusion of waste of gas-burning outside of the room through special opening in wall which is located in the place of its fastening, through it there is also air intake. The special electric turbine is for this purpose provided. It is minus of the similar equipment as depends on electricity. But, in difference from the previous design, the owner does not need to coordinate the flue device with appropriate authorities.
