Pumped heating gravity hot water, I've only ever seen gravity hot water with 28mm pipe work though.
Yes Normal for grav. But don't think that boiler is designed for grav hw. It should be a fully pumped system i would just bosh in a two port and a bypass - gate vale
When you say having damp sorted not got the injection cowboys in has he? The solution is not injection it's ventilation.
Move the pump? Or turn boiler down low?
It should have been converted to fully pumped when that boiler was installed. Shocking that it was not.
