EWR・EWS series

last updated:Mar 11, 2026

  • Official site

A wall-mounted electric water heater (open type) with a proven track record in a wide range of applications from serving tea to washing dishes in office buildings and kitchens.

Of course, it can be used in office break rooms and kitchens, and thanks to the high-temperature boiling characteristic of an open design, it can provide a generous amount of hot water for a wide range of applications. The EWR series, with its rich lineup, is our standard type at a reasonable price. We offer a variety of models to accommodate a wide range of installation sites. The EWS series is a slim model with a depth of only 190mm, making it much thinner than typical wall cabinets, so it does not create a sense of pressure even when installed in narrow spaces. Our electric water heaters achieve a high boiling temperature that is safe for drinking. When not in use on weekends, you can use the timer to save energy smartly, and on the following Monday, you can replace the water with clean, fresh water before coming to the office, with the automatic water supply and drainage function completing the boiling process. (The EWS series comes standard with the automatic water supply and drainage function.) They are widely adopted in office building break rooms and kitchens, among other applications. The EWR can also be equipped with a faucet that dispenses hot water when the tap is turned. We also accommodate other specification changes. There is a rich lineup of power specifications and heater capacities. Please consider according to the number of users and other factors.
