Is it better to use circulating machine or direct heating machine for hotel central hot water heat pump?

It is best to use a direct-heating air energy water heater with circulation function in hotel places.

When hot water is urgently needed, the hot water loop is switched to direct heating, and the hot water heated to the set temperature is directly used at the hot water user end; When hot water is not needed urgently, switch to hot water circulation mode and heat the water slowly.

According to the scale of the hotel, the hot water heating system should be equipped with a hot water storage tank with sufficient capacity and good thermal insulation performance, and the hot water should be heated and stored in the storage tank for standby when it is not in urgent need.
