Steam-Fired Instantaneous Water Heater

SQ2/SQ4/SQ6

Plentiful hot water ready in moments

With a short warm-up period, flip a switch and hot water at the desired temperature will be supplied in just 30 to 40 seconds. The hot water temperature will be maintained even if there are fluctuations in load during operation.

Current operation details are shown on the touch panel. The panel features a full range of functions including set temperature adjustment, abnormal temperature alarms, and alarm history review.

Thanks to the indirect heating method, steam and water never mix, and since stainless steel is used for the cover, frame, base, and all wetted parts, the hot water supply remains free of rust and foreign material. Clean potable water can be heated and supplied as is, without contamination. SteamAqua is certified to conform to the Water Supply Law in Japan.
