What to do if the heating system of my Vaillant ecoTEC pro 28 is not full of water?
- AAnthony TuckerAug 25, 2025
If your Vaillant Boiler's heating system isn't full of water or charged correctly, make sure the heating system is full of water and charged to between 1 and 1.5 bar. If it's not, refill and vent the system.
