Abstract
A water heater has a hot gas conduit forming a heat transfer wall enclosed by a water jacket. A series of baffles within the conduit direct jets of hot gases to impinge upon the heat transfer wall. The baffles thermally expand during operation to engage the heat transfer wall, but are removable as a unit for servicing when the heater is cool.
