This was a boiler service job I did for a customer recently in Sheffield S11. The boiler was a Vaillant ecoTEC Exclusive 832 Combi boiler. They got in touch with me because of the experience I have with Vaillant boilers and decided I was the best person for the job.
The Vaillant ecoTEC Exclusive is available as the 832 and the 838. Its a bit of a weird boiler because it is not a proper ECOTEC model in my opinion. The Exclusive is actually based on the old Vaillant ecoMAX design which they stopped manufacturing around 2005 I believe.
Relative to the other ECOTEC boilers it is a bit of an antiquated design, and a much larger boiler. The primary heat exchanger is the same that was used in the Glowworm cxi, sxi and hxi, and the same one found in the ecomax Pro and ecomax Combi boilers. It was also used in ecoMAX light commercial boilers.
On this boiler it is mostly the same as the ecoMAX but they have upgraded the domestic hot water flow sensor to an ecoTEC version and added a pressure sensor instead of a pressure switch(ecoMAX 835 didn’t have either). The only other thing that is different is the pump, printed circuit board and the user display printed circuit board, aside from these components the boiler is an ecoMAX.
I just think it’s a bit of a strange hybrid model based on an obsolete design and I’m not sure why they manufactured it. I just thought I would mention this as I don’t carry many parts for the older ecoMAX, most of the parts carry are for the ecoTEC which Exclusive isn’t despite its name.

This was a complete strip down of the boiler at the customers request. The bottom rubber seal on the burner door always fails at some point and they typically last around five years before they need to be replaced.
The service on this boiler included replacing the graphite and rubber burner door seals, recharging the expansion vessel to the correct pressure, cleaning the condensate trap and testing the pressure sensor accuracy to mention just a few things.
