Vaillant Combination Boiler / Not sure of model number
Basically, last night I decided I would run the central heating system for the first time in a good few months (summer and all that). It proved to be a huge success with all radiators warming up nicely, heating the house as expected.
However, I wake up this morning ready to shower and get out of the house only to find that I am void of any hot water. The hot water simply wasn't flowing as it should be.
Now, I'm pretty confident that this has something to do with the heating going back on.
Can anyone help shed some light on this situation?
