Heated towel rail fitted to combi system

[tortoise^123]

Our towel rail is very hot at the bottom and almost cold from about the last 3/4 rails to the top.
I have looked everywhere but all I can see are the two valves at the bottom attatched to the in and out pipes but I cant see a bleed valve, at the top of the two main struts there are like round what might be caps on there but they are fixed tight and I am not sure if they come off or not so I am reluctant to try and remove them.
This was fitted by a professional so I didnt think to ask about this but I really think it does need bleeding,
any ideas.

hi, can you put a pic up of the top ? does sound like it needs bleeding. 🙂

Hi,
Sorry mate, I cant do a picture.

Pull the covers off on top of the rad to access the bleed nipple. They are normally only plastic chrome effect and need a bit of force to get off.

As Blake says, try to remove the caps to get at a bleed valve!

Thanks for all the help guys but they look pretty solid and they are going to take some force to come off but I will try later.
Cheers

I had this on mine, turned out i must have had an airlock. Following some bleed procedure I found on the web resolved our issue.

Hi,
To everyone who has been helping me to bleed the towel rail, I have done it now as they said I removed the cap on the top right hand side main strut, just got a blade under it and there was the bleed valve, there was quite a lot of air in it so I have topped up the boiler to required level and all seems ok there you go I am 60 years old and I learn something new every day.
Thanks again guys.
