There are cumulative and running gas water heaters. A flowing water heater is a gas column that functions due to gas supply. Gas speakers, as a rule, consist of a metal case and burner, the task of which is to heat water, which is supplied through the heat exchanger. In modern columns, automation also functions. It provides safe operation of the gas column and protects it from boiling. The gas enters the burner when opening a tap with water. Since the valve for its supply opens simultaneously with water. All gas combustion products go through the chimney, which is located in the upper part of the box, and hot water is already supplied through the pipe. There are two options for the ignition of the burner – electric and pyzo. The gas column equipped with a pusher. Когда колонка отключена – горит только запальный фитиль. When opening a tap with water, the wick brushes again.
The speakers with electric ignition turn on automatically. This is due to the electric spark from the batteries. Such columns are considered economical. After all, they do not have a faint on which the wick should constantly burn.
Modern speakers are equipped with a special protection system in case of emergency. They automatically turn off when the flame is extinction, the absence of water in the heat exchanger, with overheating, gas leak, with a weak chimney thrust. Due to their compactness, such columns are widely used by the population. A big plus of these gas stems is their performance. The volume of hot water supply is about 10-17 l/min and this is at water pressure 0.1- 1.0 atm. and capacities 17-30 kW.
Regarding gas storage water heaters. The scope of their use is slightly limited due to large dimensions. But if the area allows, it is better to install such water heaters. Such devices consist of a heat -insulated tank of a cylindrical shape. At the top of this tank a chimney is bred, there is a burner below.
The accumulative gas water heater, like gas columns, has a control and protection system: a thermometer that controls the temperature of the water heating, thermostat of both the main and duplicate and the heating indicator. These water heaters have a sufficient volume of 150 liters and are equipped with a powerful gas burner (7-26 kW). Such technical capabilities allow you to stock up on hot water for a certain time and provide about four points of water.
