The main advantage of the gas water heater over an electric one is its economy.
Usually, tariffs on electricity are higher than on gas. For the rest, a gas water heater has practically no difference in its consumer properties from an electric heater. Because unit heaters are different, repair the equipment would be different too. For example if the water heater will run. Gas water heaters vary in power consuming. If you do not need to use both a shower and, for example, wash dishes in the kitchen at the same time heater consuming 18-19 kW is quite suitable; but if you'd like to use the shower and some water in the kitchen at the same time, it is necessary to choose water heater consuming 24 kW. Properties of the gas tank: • no need in electricity • cost-effectiveness • requires gas supply to the location of the heater, that’s why the price is significantly higher comparing to the cost of electric water heater. Gas water heaters are divided into two groups: tanks with piezoelectric and tanks with electronic ignition. Gas column, which is fueled with matches, is currently out of date. In a heater with piezo ignition a burner is igniter, and flame is kept all the time. Activation of the igniter is done by pressing the button of the piezoelectric element, which serves as a source of electrical current, allowing sparks that can ignite the flame appear. Flaming ignition flame is an indicator of the standby mode. To start the gas heater one needs just open the tap of water supply. Tanks with electronic ignition work in other way. In the standby mode the flame ignition isn’t lit and, consequently, there is no gas consumption. The device is switched on with turning the regulator on the outside of the unit on the power consumption required. Once the hot water tap is opened, the electronic ignition instantly ignites the flame and the main burner after that. When hot water stops running, tank is automatically disconnected from the gas line and goes into standby mode. Leaking water in heater [more] happens quite often in case of improper use. If your water heater is running, than take into account that there is only one spare part that contains a rubber or paronite stopwater. It’s a tan. To replace the stopwater remove plastic protection near thermostat, block the cold water, drain water from the water heater (formerly preparing the hoses reaching the sewage system), disconnect the pipe of the water heater, and connect the hose instead. After the complete draining of water unscrew the tan counterclockwise, and change the gasket. Assemble in reverse order. Water heaters with dry heating elements make an exception. There heating elements don’t contact with water. In these water heaters there is a inspection cover under a plastic layer. It has a contact with water as well as tan in the preceding description, but the first one is secured with six screws. In all cases when water is running not because of malfunction of a stopwater the tank needs replacing, or repair that is very time-consuming and costly. Therefore, it’s better to look for professionals to repair water heaters and pick a good company that sells and installs water heaters. The more so is because the gas equipment is easily damaged or set incorrectly, that would cause more expensive repairs. In any case, gas water heater will last a long time, if you will promptly take care of him and monitor its condition.
