well, it's not unsafe, if it was the boiler would have been plastered in health and safety labels and cut of with written letters and all sorts. As for the "red thingy" that is a little ambiguous as there can be many "red thingy's" in some boilers, but it is hard to decipher with...

it could be the pump maybe faulty, or cold feed may be blocked, but it probably is just one of those jobs that i would have to see before making a judgement

hard to say, some have a lever on the pressure reducing valve, others it is a separate isolation tap. It may not even be the isolation valve, could be that the pressure reducing valve is alittle clogged up.

if the leak is sufficient, it could be enough to activate the boiler to come on briefly on dhw mode. Best thing to do is get a gas safe eng round to have a look, as it can be quite hard to say online. I'm not aware of any particular faults on the greenstar that can cause those symptoms. I know there...

i would agree, if it isn't broken don't fix it, but seeing as it will likely break sooner rather then later, we can all be in the unique position of all having different opinions and still all being correct. Besides parts for ferrolli tend be be expensive, so while they are available, it probably wo...

you don't always have to bleed a pump, only if it is air-locked and squeals after you refill the system. A less effective way is to start and stop the pump several times in quick succession, that can sometimes clear a minor airlock, but having the pump under the floorboard is a pretty daft place to ...
