Heating systems
Common uses:
Boiler/hydronic heating
Ground-source heat pumps
Radiant floor heating
Hydronic and fan-coil heating
Solar heating
Heat recovery/heat pumps
Pump types with cast iron pump housing are generally used for these applications, considered to be closed systems, for pumping water or water/glycol mixtures. However, when water conditions are not compatible with cast iron, we recommend the use of bronze or stainless steel.
Optional variable-speed and mixing-reset controls are available to customize heat output vs heat demand for increased comfort.
