The DNM mini instantaneous water heater is designed for supplying a single draw-off point where hot water is required infrequently and in small volumes. It heats the water very quickly at a DHW output of up to two and a half litres per minute. Its small dimensions enable flexible installation even in the tightest of spaces. The DNM is suitable for oversink or undersink installation. The installation requires special taps for mini instantaneous water heaters.
