At present, the best solution in public places is direct drinking water equipment, which saves money, saves energy, is healthy and convenient.

Secondly: the choice of direct drinking machine depends not only on the brand, but also on whether the product configuration meets the needs of the place. Let me give you a suggestion:

1, whether the hot water output of the machine can meet the uninterrupted water supply of many people; (depending on heater, heating technology and heating power)

2. Water treatment: Reverse osmosis is the best choice to improve the taste. If tap water is directly boiled, the experience of members will be greatly reduced. For reverse osmosis wastewater, if it is municipal water, the current wastewater ratio of reverse osmosis technology can reach 1: 1, or even lower (if it is groundwater, just adjust the pretreatment), even if there is wastewater, it will not cost much (one ton).

3, the appearance of the machine, the plastic shell will fade after a long time, which will inevitably affect the appearance. It is recommended to paint the fuselage in a stainless steel room.

4. Energy-saving technology: The heating technology of direct drinking machine can be divided into boiling type, stepping type and instant heating type. At present, all the direct drinking machines with plastic shells on the market are boiling, which has the defect of energy consumption of yin and yang water and boiling water. According to your budget, the latter two heating technologies are recommended.

5. Construction: Under the premise of not damaging the beauty of the site, the water source is taken nearby, and it is no problem to send the wastewater to the roof or go to the geosyncline.

To sum up, it is recommended to use the direct drinking machine, 304 stainless steel liner, 20 liters in places with 50-80 people, and the boiling water flow per hour is more than 30 liters, so as to meet the demand of uninterrupted water supply for 50 people.
