Hi guys
I'm putting in a new toilet, rad and sink in my grandparents downstairs toilet. I've just fitted a full bathroom in my house so thought this would be easy. I've damn well fallen at the first hurdle. I've got a combi boiler and they have a conventional boiler with hot water tank upstairs. I'm totally confused still. Despite reading the FAQ I still can't see how this system is filled! Also, the FAQ mentioned about zones for draining the rad!
I need to drain the radiator so I can relocate it. Is the system closed, from what I have read it seems like I simply turn off the boiler, turn off the cold water supply (is this needed?) and then start draining the radiator! In the garage there are about 5 copper pipes all coming down with drain valves... I guess these are for the different zones I read about. How do you know which is which??
Also, when it comes to refilling, I don't see how to do this!! Is it simply a case of turning the boiler all back on and the auto valve will open to refill the rads....then just a case of bleeding them to run the water through?
I'm really sorry...I appreciate this is totally basic stuff but it all made perfect sense with the combi boiler in my house yet I can't get into my head how there system works!
I can turn off the hot water from the tank. There is a red round handled stop coming in from the cold water tank in the loft - this is what I've used to turn off the hot water
There is also a pipe coming from the bottom side of the boiler which is warm just going down into the floor boards and then there is another hot pipe coming from the bottom of the boiler which splits, one side going to the water pump and one side going to another red circular stop tap and then under the floor boards (what does that stop do?)
There is also another circular red stop on a pipe which looks to be going straight up into the ceiling - I presume this is the vent I read about?
I know these area basic questions but I just can't get my head around it! All I want to do is drain the rad and refill it!
Any help, advice or info would be much appreciated!!
