I noted with interest that there were a few central heating engineers on the site and I was wondering if any of you could give me some advice.
I have a worcester combi 28 cdi and 10 radiators in my 3 bed semi.
I have a problem with the big double rad in the front room. It only gets hot at the top and the bottom is cool so it's probably sludged up.
Ideally I would like a powerflush but there are two things stopping me.
1. I got quoted £400 from a local firm.
2. The other rads seem fine.
The way I see it, there are two possible options.
A) Take the double rad off the wall and blast the rubbish out
B) Use Sentinel x.400 in the system for a few weeks followed by a flush and then refill with x.100 rust inhibitor.
What do you guys think is best?
