An improved in-line tankless electrical resistance water heater includes removable brass bottom and top flanges to form an internal chamber in a tubular body. The top brass flange has a cold water inlet and a hot water outlet for connection to a hot water line. The water heater includes an internal passageway through which cold water travels into a flow sensing/heat element activating device and then into the internal chamber. An enlarged double-coiled heating element passes through the bottom flange and a bracket holds sealing elements firmly against connecting ends of the heating element to seal the connecting ends and firmly hold the heating element in place.
