What should the target flow temp be on a Vaillant boiler?
What should the target flow temp be on a Vaillant boiler?
To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Once you’ve got your boiler running at the optimal temperature, you’ll want to set the timer for when you need heating the most.
What happens when an expansion vessel fails?
If the expansion tank is missing or not operating properly, pressure in the system may cause the boiler’s pressure relief valve to vent water. Or, air bubbles being released by the heating water may gather somewhere else in the system, causing a blockage that stops the flow of hot water.
What number should the boiler be on?
When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure.

The book says that the built in filling loops are only on the Ecotec PLUS models. Although of course books often get it wrong! The taps are light grey, and are definitely the ones supplied as part of the boiler, which is an Ecotec plus 831. They are both in the closed position.
