If you open a bath hall (single room above 10), what kind of boiler is used and what is the principle? (For example, the pressure of cold water and hot water.

1, as you said, a small atmospheric hot water boiler is enough (0. 17MW is enough).

2. If the coal-fired boiler is allowed in that place, it is better to use this special boiler for bathing made in Linyi, which is more energy-saving. The principle is multiple round trips and high thermal efficiency.

3. If you can't use a coal-fired boiler, you'd better use a gas-fired boiler, that is, the gas charge is higher.

Nowadays, most of the bath halls are hot water pipes, so that the water boiled by the boiler is directly placed in the hot water tank at about 42 degrees, and then transmitted to the shower head through natural pressure.

5. If cold water pipes and hot water pipes are designed, there are the following connections:

(1) The hot and cold water tanks are all equipped with variable frequency pumps, so that the pressure of hot and cold water is consistent and the effect is the best. The water tanks do not need to be placed on the roof (generally used in high-end hotels).

(2) The two hot and cold water tanks are the same size and placed on the roof. Try to keep the same water level, so as to balance the pressure (this can save the cost of the water pump, but the water level is not easy to control).

(3) Add a water pump with the same flow and lift to each of the two hot and cold water tanks, and then set a return pipe to return to their respective water tanks (this will save the cost of the inverter than (1), but increase the return pipe, and the power consumption of the water pump will be more).
