Hot water supply in hotels such as Home Inns, Seven Days, Jinjiang Inn and Super 8 (high score)

For small hotels, I suggest you use a commercial positive displacement gas water heater. Why use gas? Because the operating cost of electricity consumption is higher than that of gas consumption, (American) water heaters do not need to add additional water tanks, reducing the daily heat loss of water tanks, and the operating cost of 40 rooms can be reduced by 3000-5000 a year; Moreover, the installation does not occupy space, and a single installation can be installed in any small corner of 1- 1.5 square meters; The weight is not heavy, and the weight of a single unit plus water is about 400 kg, regardless of the bearing capacity of the floor; When it is running, the sound is very low, even if it is next to the room, it can be used online by one or more people. If it is installed in the future, you can add one to the hotel in case of insufficient hot water.
