Installations which have a long pipe run to the final hot water tap or shower may suffer from excessive

draw-off (and therefore wastage) of water that has cooled in the pipe, before the required hot water

is available. A secondary hot water circuit with circulating pump will overcome the problem, ensuring

that no water is wasted, because hot water is immediately available even from the tap furthest from

the storage point. A standard pump would fail prematurely in this application; the pump body is

bronze so that it does not react with the regularly replenished (and therefore oxygenated) water.

The bronze pump should be installed in a return loop added to the hot water supply plumbing after

the furthest tap in the circuit. The return tapping should be into the upper third of the hot water

storage tank (in order to avoid de-stratifying the tank contents). Control methods include:

  • Run the secondary re-circulation pump from the timer / programmer hot water output (least


  • Run the secondary re-circulation pump on a cycle timer for short periods at intervals during

programmed hot water output times.

  • Run the secondary re-circulation pump from the timer / programmer hot water output, in

series with a pipe thermostat fitted to the re-circulation loop, after the last tap. The pipe

thermostat should be adjusted to 50C below the main hot water tank thermostat. (Highest


All pipes should be well insulated in order to minimise heat loss.
