Want to know more about the principle of central water heater, etc.
The principle of the central water heater is:1. Use high power heater to heat the boiler and supply water while heating. Direct heating water supply. Many are used in relatively small water supply places.2, the use of high-power heaters, heating boilers, water heating, stored in large thermal insulation water tank, to reach the temperature, automatically stop heating, after the temperature is reduced, automatically start heating. A booster pump is installed at the water outlet end of the heat insulating water tank, and then hot water is returned to the heat preservation water tank after each water outlet (water point) so as to achieve hot water outflow when the hot water outlet is opened. More used in large water supply sites. Factories such as tens of thousands of people are heating in this way. But there is no return water device, because there is backwater device, it is easy to heat loss. But it's less comfortable to use.

The central water heater, heating device, coal-fired boiler, boiler diesel, heavy oil boiler, gas boiler, electric boiler, heat pump water heater, solar thermal engineering, also has a large central air-conditioning, central air-conditioning can also be equipped with heat recovery device in high temperature season, can be "free" the hot water.Coal, diesel oil, heavy oil, natural gas, use of non renewable energy, the development in the future will be less and less, but their advantage is that you can easily achieve high power, high water content, high calorific value of them. Electric boiler, heat pump water heater, belonging to water heaters, electric heating is stable, is not affected by the weather and environment (heat pump water heater, except when the weather is too cold, can't use, such as in the north is rarely used, is currently mainly in the South); solar central heating engineering, solar central heating project is relatively easy the weather in the process of using (rainy days, snow) effect, more so in the process of application and other coal-fired boilers, diesel boiler, oil boiler, gas boiler, hot water boiler and heating stability using collocation.
