Recommended Hot Water Temperature

[newboy99]

Hi Guys
We live in a hard water area and when we moved in we were advised to have the hot water cylinder thermostat set to 55 degrees.
But it's an indirect system so I'm thinking that it should (in theory) never fur up inside.
Would you agree and if so, is 60 degrees a sensible temperature to select.
Many thanks

60 will be OK with the cyl stat fitted one third up from the bottom of the cylinder

the cylinder `stat is there to sense the amount of stored hot water more than the actual temperature at the top of the cylinder. There is always a temperature gradient from top to bottom, so the temperature at the draw-off will be higher than the `stat setting.

Set the `stat to whatever gives enough hot water in the cylinder for your needs. The actual water temperature may approach the heating water temperature set on the boiler.

Set the cylinder stat too high, and it will never be satisfied, and never shut off the boiler.

Immersion heater stats are normally factory-set at 60°C.
