Fits well.
Fits Vaillant ecoTEC plus 832 perfectly and solved my problem for much cheaper than the original. No need for a plumber for this job.

This is an OE product. Excellent quality
This is a Zilmet unit, exactly the same that Vaillant fit into their boilers. Mine failed and actually started leaking water and it left us without heating or hot water. Called a couple of local plumbers merchants who wanted an obscene amount of money for one of these. Amazon to the rescue, and it came from Unvented Components who I have used before. This fitted in literally five minutes and the boiler is back up and working again. The expansion vessels have a life or around 10 years, so check your serial number of your boiler to see when it was installed before it fails on you. The second two digits are the year your boiler was made. It caused the F.75 error on the boiler and in my case I had to replace the pressure sensor as well.

Passt wunderbar
Ein erfolgreicher Austausch hier. Sieht genauso aus, wie das defekte Teil. Einfache Installation- vorher Heizung drucklos machen. Warum das Original über 270 Euro kosten muss, weiß ich nicht. Eventuell weiß ich es nach 5 Jahren, glaube ich aber nicht
