Hot water temperature issue

[Chris*****]

I have a hot water cylinder and a cold water tank in the loft. We have just had a new system boiler fitted, Viessmann Vitodens 100-w and the domestic hot water is hot but not as hot as before. I can’t see how I can turn this up, the boiler manual says to press on the touch screen until a tap icon is shown but there is no such icon. For reasons I’m not going into I can’t contact the installer so wondered if I could get help here.
Thanks in advance..

Surly you mean on your "YorkyShiire Estate" Sir?
We don't have humble abodes in Yorkshire - aka God's Own County!

Lol , you maybe right , when we moved in here my pal called it “ southfork “

So, Yorkshire's version of JR? Or is it Sue Ellen?😉

Any chance you can post a pic of your front panel - there are various different versions of the Vitodens 100, including a 4 pipe version that heats the hot water on a separate circuit (and doesn't need a cylinder stat).

I have a Vitodens 100 too but it's a heat only boiler with 2 pipes, a cyclinder stat (set at 65) and 3 port valve, and no touch screen - I'm just interested in how you have yours set up as I have to run mine at near max to get decent heating and hot water. Boiler temp runs at a steady 72 degrees when it's modulating so all's good, but just feels weird having to have the temp dial on max (it's actually off the scale!).
