What temperature should I set my Vaillant ecoTEC boiler?

Your boiler controls explained
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. With a combi boiler, hot water is on demand.

Accordingly, what temperature should a Vaillant boiler be set at?

If the boiler is heating hot water then it will need to be set at least 5-6° above the target hot water temperature which is ideally set to 55° making the boiler need to be at least 60°.

Similarly, how do you know if your boiler is overheating? A build-up of limescale, sludge and other debris in the central heating system can be detected before the boiler will begin to overheat. If you've noticed that any strange sounds from your central heating system or that any radiators haven't been heating up properly, then they're strong indications of a blockage.

Also Know, what is the ideal temperature for a boiler?

180°F.
