How to Adjust the Water Temperature of a Hot Water Boiler Test your tap water temperature. Allow the water to run until it is fully hot and fill up a tall glass. Adjust the thermostat. Turn the knob on the side of the tank. Rotate the thermostat control.
Can you control temperature on a boiler?
Adjusting the temperature of water from a combi boiler You will have two separate controls: tap and radiator. Adjusting one should not affect the other. Turn the temperature of the tap control down a touch, then perform the thermometer test again.
What is the ideal temperature for a boiler?
Setting the boiler temperature As a rule, setting your heating control to 75 degrees should be sufficient to give you a perfectly warm house, while also allowing your boiler to run as economically as possible. Once this is set, you shouldn’t need to adjust it.
How do you adjust the temperature on a combi boiler?
First and foremost, locate the two dials and the digital display on the front of your combi boiler. These control the output temperature for the radiators and the hot water temperature. To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees.
Why is my boiler temperature low?
Low boiler pressure can be caused by issues such as a system leak, recently bled radiators or a failed component or seal. To help identify the issue, you could firstly look for visible signs of a leak, but you should not attempt to remove any casings from the boiler.
What temperature should a boiler be set at UK?
