Excuse me, how to design the gas-fired boiler in Room l28 of the hotel to provide domestic hot water?

a water storage tank with a capacity of more than 1 tons is set, and the boiler is connected with a circulating pump through a circulating pipeline, which is fully controlled. For example, when the water temperature in the water storage tank is lower than 45 degrees, the circulating water pump will start, and the boiler will automatically work at the same time. When the water temperature in the water storage tank reaches 6 degrees, the boiler will stop working, and the water pump will stop circulating for 2 minutes. This step has completed the hot water reserve, and then hot water will be used. Laying a main circulating pipeline through each room, connecting the circulating pipeline with a rear circulating pump, and connecting the water points of each room from the circulating pipeline; Fully automatic control, when the water temperature of the circulating pipeline is lower than 4 degrees, the rear circulating pump starts, and stops when it approaches the water temperature of the water storage tank, which really supplies water all day, that is, it is ready to use.
