Problems that often happen in communal services and lead to a lack of hot water stimulate us to buy water heaters. And if you still have to look for a place for a boiler, then the running water heater is a compact device (some models can even be called miniature). For such a device, you can find a place even in the smallest room. Main plus
instantaneous water heaters is their small size and quick heating of an unlimited amount of water. This is really convenient: immediately after turning on the device, get warm or hot water at the outlet.
Types of running water heaters
By the type of heating element, these devices are gas or electric. A gas-fired running water heater is the most economical option: gas costs less than electricity. And the heating efficiency in units of this type is higher: the water is heated in a heat exchanger pipe, which is heated by a gas burner. Modern models of gas columns have the function of electric ignition, and many allow you to set the temperature of the outlet water. This is convenient if you intend to use a flowing water heater for a shower. To ensure safety, there is a "Gas Control" function: when the gas disappears, the column is automatically turned off. There are also sensors that monitor the temperature of the water: if it approaches the boiling point, the flame is extinguished, the column remains in working condition.
Electric flowing
water heaters have long and firmly “taken root” in dachas and in country houses, in apartments where there is no natural gas. Most often they have a large capacity, which allows you to quickly heat large volumes of water. But a lot of power leads to the need to conduct a separate power line (if it was not previously provided). A separate line is a guarantee of safety, and you should not neglect this requirement. In addition, if the power exceeds 10kW, a three-phase power supply is required. If this is a problem, choose a less powerful model.
The device of an electric instantaneous water heater
Water heating in a device of this type occurs in a flask in which a heater or a spiral is placed. If your water is hard, it is advisable to choose a flowing water heater with a spiral: the design of this heating element prevents scale formation, which significantly prolongs the life of the device. The maximum heating temperature is 55-57 ° C, this is enough to take a shower or wash the dishes.
Price policy
The price of a running water heater depends on its capacity, manufacturer and technical specifications. The most budget option can be purchased for $ 45-50. But its service life (even under normal operating conditions) does not exceed two years. With the increase in price, the working resource also grows. There are models that cost thousands of dollars, but these models have a built-in microcomputer that controls the temperature of the water with great accuracy.
