Mother in Law had a visit from BG 3* cover people....

Her radiators upstairs are getting hot even though the CH is most
certainly off.  Hw is on for a couple of hours in the AM and PM.

I was there for their visit - but they told her she urgently needs a
system flush and something about an "anti-gravity" valve........and the
cost for the "repair"........599 +VAT.

I had BG telling me I needed a system flush - but I did it myself after
hiring the necessary equipment for 100.  Do the experts amongst you
agree that hot radiators upstairs is down to this - sounds fishy to me
(but I really am not an expert!!!!)

Grateful for some advice please
