A hot water circulating pump and check valve are installed on the return line and controlled by a timer or an Aquastat. The timer turns on the pump at preset intervals, usually during peak use periods in the early morning and late afternoon. An optional Aquastat operates the pump to keep hot water in the line within a set range (95°F–115°F). All supply and return lines should be insulated for maximum energy savings.
