Anyone had luck removing air from a system with a Vaillant stackable 30l buffer tank ?
This has no air vents and all pipes enter half way up.

Has your buffer tank not got an outlet at the top you could loosen off gently and bleed the air out.
I have a 27 litre volumizer with an automatic air vent screwed into the top.
Hi Keith. Unfortunately not.
The buffer tank is designed to fit under the hot water tank without a gap. There is nowhere for an air vent on the top.
There is a picture on Vaillant website if you are interested and search for unistor plus slimline.
Cheers,
Nick
