Indirect |
| Indirect water heaters are heaters with no internal means built into them to independently produce hot water. Instead they rely on heated water piped to them by a boiler. The heated boiler water is circulated either through a coil in the tank or in a jacket surrounding the exterior surface of the tank unit containing cold water. The hot water produced by this process is then pumped through piping to wherever it is needed to be used as hot water or to provide heat in the spaces requiring it. | |
