1. Čeprav ima tip takojšnjega ogrevanja veliko moč, je čas ogrevanja kratek in vroča voda se hitro proizvede. Na primer, trenutni električni grelnik vode ANTO lahko proizvede toplo vodo v samo 3 sekundah. Nasprotno, čeprav je moč električnega grelnika vode "velik cilinder" majhna, traja od 40 minute do 1,5 ure za pripravo tople vode. Električni grelnik vode ANTO brez rezervoarja lahko samodejno prilagodi moč ogrevanja glede na temperaturo vstopne vode. Spomladi, jeseni in poleti lahko le 1-3KW izpolni zahteve glede temperature vode za kopanje. Povprečni čas kopanja je okoli 0,6 juana na osebo.

2. Whether the instant water heater costs electricity is not based on the power, but depends on whether the electric energy used is wasted. Instant electric water heaters do not need to be preheated, do not need to store hot water, and consume as much electric energy as they use, saving water without any waste of electric energy. However, in traditional storage-type electric water heaters, if you want to use hot water at any time, you need to power on for 24 hours for heat preservation, and heat preservation will lead to heat dissipation. Taken together, about 2 kilowatt-hours of electricity is wasted a day.
