Hot water Temperature

[plastic_peanut]

Evening all,

Hoping for a bit of help if you can. Our viessmann vitodens 100 boiler appears to be functioning fine however the temperature of the bath water appears to be noticeably cooler of late.

The temperature of the separate shower’s water is plenty hot enough but not the bath. Can anyone make any suggestions as to what could be the cause please?
It is being run in Eco rather than comfort and the temperature is showing as around 54 degC.
In a previous house we had issues with a thermostatic valve causing issues but our house doesn’t have a hot water cylinder.

Any suggestions would be appreciated.

Cheers

At full flow boiler is designed to raise water temperature by 35 degrees. As incoming water temperature has dropped due to the weather you will need to limit the flow a little to get the desired temp

Thanks for this, I assume you mean limit the flow with the tap?
It isn’t particularly fast running anyway but will give it a go.

Cheers
