How to Adjust the Water Temperature of a Hot Water Boiler

The water should be a minimum of 120 degrees Fahrenheit. If it is less, adjust your hot water boiler upwards. If the temperature is well above 120 degrees, you can safely adjust your hot water heater downward slightly before testing again to be sure you maintain the recommended minimum temperature at the tap.

Boiler Pressure Too High, Low, Keeps Rising, Dropping

Combi boiler pressure increases when the heating is on as your boiler uses fuel (gas, oil etc) to heat the water - this increase in pressure is natural. If your boiler is behaving as it should, the pressure will stabilise again once the system is switched off and cooled down.
