Different preheat levels for inner and peripheral walls limit vapor in the intermediate collector and prevent steam tube overheating.
A restricted air supply opening and partition plate layout suppress pressure fluctuation, oscillating combustion, and noise in compact water heaters.
A perforated core and spacer layout spreads dry vapor steam evenly over sensitive instruments, improving sanitization speed without heat damage.
