How to heat the hotel water heater?

The hotel's water heater uses a high-power heater to heat the boiler and supply water while heating. It is called direct hot water supply. Mostly used in relatively small water supply places.

Hotel central hot water-the principle of hotel central hot water

The boiler is heated by a high-power heater, and the water is stored in a large heat preservation water tank after heating. Stop heating automatically when the temperature is reached, and start heating automatically when the temperature is lowered. A booster pump is installed at the water outlet end of the heat preservation water tank, and hot water flows back to the heat preservation water tank after passing through various water outlets (water consumption points), so that the hot water flows out when the hot water outlet is opened.

Widely used in large water supply places. For example, factories with tens of thousands of people provide heat in this way. But there are also those without backwater devices, because it is easy to dissipate heat after having backwater devices. But it is not so comfortable to use.

Hotel central hot water-hotel central hot water equipment

The central hot water and heating equipment of the hotel include: coal-fired boiler, diesel boiler, heavy oil boiler, natural gas boiler, electric boiler, heat pump water heater, solar heat collection project, etc. In addition, where there is a large central air conditioner, the central air conditioner can also be equipped with a waste heat recovery device, so that "free" hot water can be obtained in high temperature season.

Coal, diesel, heavy oil and natural gas are all non-renewable energy sources, which will be less and less in the future development. However, they have the advantages of high power, large amount of water supply and high calorific value. Both electric boilers and heat pump water heaters are electrically heated water heaters, which work stably and are not affected by the weather environment (except heat pump water heaters, which can't be used when the weather is too cold, for example, they are rarely used in the north and are mainly used in the south at present).

Solar central heating project, which is easily affected by the weather (rainy day and snowy day) during use, is often used in conjunction with other coal-fired boilers, diesel boilers, heavy oil boilers, natural gas boilers, electric boilers and other hot water boilers with stable heating.
