Also if it was gasses how long would it take them to build up again so how long roughly would the rad need bled again you talking weeks or months I’m not sure I want to continually spend the winter touching radiators lol

Ok thanks everyone seems a bit more complex than I had hoped I was hoping it may just be air from refil??
Next time you bleed, check to see if the gas coming out will burn.
What does the control prove? If the rad water shows no rust on the test, it's OK, if it shows rust, need to add inhibitor. Whatever the tap water test does.This test needs two separate samples of water in sealed containers. One from the heating system and one from the kitchen tap to act as a control.
Please yourself, but it's not exactly a Wehrmacht WW2 flamethrower! I've done it a few times. It's only a flame about 20mm long. You could let it burn until water starts coming out, when it will go out, or put your thumb over it to put it out. Obviously you'll make sure there are no curtains etc hanging near, or you might set them alight with your match, irrespective of any burning gas!Yeh I’m not sure I want to start fires from gasses in my house to be honest unless it’s my hob

OK fair enough, knowing how long the tap water sample takes to go rusty gives useful information. If the rad water test is OK at that point I would put it to one side and check it every week or so for several weeks, to make sure.It's to show that the nail has been in the water long enough for a noticeable amount of corrosion to occur in untreated water.
Strictly speaking, one should drive the nail through a couple of cm of copper pipe and use that that as the test sample.
