Worcester boiler

[Steveohim]

Does anyone know why my boiler will only produce warm water in the winter?
The rest of the year is fine

Assuming combi boiler, the cold water coming in is at a lower temperature and only being heated the same amount so the temp coming out of taps will be slightly lower
You may have to turn the temp up on the boiler to compensate through the colder months

As above, try running the tap slower too

This is why 24kW combis aren't a good idea.
