What temperature should the hot water cylinder be set to?
60-65ºC
A domestic hot water cylinder thermostat should be set at 60-65ºC. This is high enough to kill off harmful bacteria such as Legionella. If you set the thermostat much higher than this the water that comes out of the taps will be too hot and there’ll be a risk of scalding.

How long does it take for hot water cylinder to heat up?
A hot water cylinder heated by a boiler can be re-heated from cold, usually within 30 to 45 minutes, depending on the type of boiler and size of hot water cylinder.
How to increase hot water temp in cylinder safe?
Look for temperature control in here and turn up by 5 degrees. Replace cap. Re-instate electrics. Turn off electrical supplies to immersion heaters. Remove cap from lower immersion.

Is there a way to increase hot water temp?
Yes, you would get more “hot water” because you would be using less from the cylinder and more from the cold to mix it down.

How can I change the temperature of my hot water heater?
If your hot water isn’t the right temperature, you can adjust it in a few minutes. For gas heaters, all you need to do is twist the temperature dial at bottom of the heater. For electric heaters, you’ll need to remove the access panel and insulation covering to access the temperature dial.
Why does hot water rise to the top of the cylinder?

How does the pressure in a hot water heater increase?
Hot water pressure increase in a water heater. A 40 gallon water heater with 80 PSI line pressure will build to a pressure of 145 PSI with a temperature increase of 16°F. (Brandford White 2019) That’s a 65 psi increase occurring from a 16°F temperature increase, or roughly 4 psi increase for every 1°F of temperature increase.
