Table 2. Jaguar boiler recommended pump models for domestic hot water tank piping.

Notes:

*This is the minimum flow rate recommended for Jaguar boiler.

**Domestic water tank piping head is based on 1” inside diameter piping and full port valves.

***Refer to the DHW Tank Manufacturer’s water flow rate requirements and associated pressure drop head loss, to select the appropriate circulator.

▲If 2 circulators are specified, they must be piped in series in order to provide the head capacity shown. Power to circulator(s) must be supplied through an appropriate relay to protect the boiler control’s fuse.
