DHW Recirculation/ Boiler Mounting

Domestic Hot Water Recirculation

DHW recirculation lines increase the level of comfort and

convenience of the domestic hot water supply and reduce

water consumption.

These advantages directly derive from the immediate

availability of domestic hot water at all draw points.

Poor insulation of the DHW recirculation line, however,

can result in considerable heat loss. Viessmann therefore

recommends that effective insulation be provided and

used for DHW recirculation lines of 23 ft. (7 m) in length

or longer.
