BAXI 105E Boiler water problem

[JFD7000]

I have a Baxi 105e boiler that came with the house.

When we moved in everything worked fine.

Now the heating is working ok but the water is not very hot. Were is used to rise to 80 degrees C , it only goes to 70.

Any ideas

Passing divertor valve,
Faulty thermistors,
Poor gas pressures,
clogged up heat exchangers

or simply

Winter temperature cold mains!

Combi's always decrease the water temp in winter as the water coming into the house is so much colder.

Run the tap slower to see if that helps
