    Internal layout of a three-pass fire-tube boiler. Package boilers are commonly called water or fire tube Boilers.

    Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

    erosion of a boiler's plates from the internal water space, particularly where there is a step inside the shell.

In later years it was a problem for the non-circular water drums of Yarrow boilers. Handhole
