Viessmann Combi
A friend (as in the Flue question) has had a combi fitted upstairs (new flue
through roof). The fitter did a great job, but the electrician needs to come
in 2 weeks after my friend returns from holiday - therefore it is running
without a room stat at present.
He is concerned about the noise and some of his family have switched it off
at the spur unit. My instinct is that this is a bad idea as it could upset
the pump or fan control. However, what is the noise - is it a fan?
