Yes its a bit confusing for the layman like me to decode the boiler specs :) The install guide (linked below) mentions the following for the ecotec plus 832 (model in the tables is VUW 25/32): - Flow rate (ΔT = 35 K) = 13.0 l/min - Flow rate limiter = 10.4 l/min I didnt intially spot...

Thanks - if no luck with Vaillant engineer then will try removing to see if it makes a difference. Not sure if these are snake oil, but afaik its part of the compliance kit for the 10 yr warranty

Its connected: Mains ---> Main stop cock ---> boiler isolation valve ---> Cal mag scale inhibitor ---> boiler Yes thats what I saw also - 1.08l/sec = ~65l/min so that is much higher than the supply.

Measured both kitchen and utility taps (one floor below boiler). Both are about 4.8l/min tested individually

Good point on measuring the traditional way :) Will post back... Re filters the CH circuit has a magnaclean (pre-existing) + the vaillant mandated magnetic filter (obs not related to the DWH) The CW inlet to the boiler has a "Cal Mag" inline scale inhibitor between the isolation valve and boiler.

With just one tap it was 4.79l/m (kitchen tap) Cant measure anything else as I dont own a measure cup (was installer) not access to the installer menu on boiler. Thanks for the reply

Thanks for reply. Correct - 6.5l/m w shower on and 7.8l/m with shower + 2 hot taps measured on boiler display. (I assume D.036 is the vaillant code for that measurement?) We haver measured at tap using measure cup and was ~4-5l/m. Mains stopcock and valve on the boiler CW inlet are both fully...

Our 17+ year old Worcester Bosch GREENSTAR 24i Junior recently broke (again) so it got replaced with a Vallant Ecotec Plus 832 (facelift version with screen). This was upsized from the previous 24kw because of extensions in our home since the WB was fitted - 6 more rads and additional shower...
