We've not long been in possession of our new house and i'm trying to get my head round some of the plumbing.
The heating system is only a couple of years old and seems quite noisy. I'm used to a virtually silent system but there is some definite pump noise that you can hear in the rooms adjacent to the airing cupboard where the megaflo and heating system pump are located.
The first thing i noticed is that there is a gate valve fitted in the return to the boiler from the megaflo coil. The valve seems to be about half open.
Any reason why this should be there and why it shouldn't be fully open? I can find no reference to the requirement for a gate valve in the megaflo fitting instructions and can only assume its been fitted to slow down the water flow through the megaflo.
