  1. If this really is the service you personally are carrying out then yes it's good value SHOULD ALL THOSE EXTRAS REQUIRE DOING. If no rads need replacing, if the system is fairly standard, and if the pump is fine, then it looks rather costly. My personal experience of BG powerflushes has involved the guy plumbing in the unit and sitting back with copious cups of tea for 3 -4 hours. I'm sorry to generalise, and I'm sure there are also good responsible engineers amongst BG's crew, but I'm rather cynical towards any firm that demands targets of their engineers that inevitably lead to short cuts.
  2. £666!!! That's way over the top!! Our company charge abouy £500 and that's expensive. Shop around for about £400, or find someone who'll do a foreigner. I'm doing one this weekend for £250.
  3. Look out for the following: A cold zone at the bottom of most rads when the heating is on, probably shaped like a hump (build up of sludge in the rad). Boiler whines, or bangs slightly, pressure builds past 2bar when boiler is fired up (if you have a gauge). Cold spots on the top of rads is air, just bleed them. A proper flush should involve banging of each rad to help shift the sludge.
  4. I'm a Heating Engineer. I think you've been sold a dud. A powerflush could help, as sludge in rads creates gasses, but I'd check for other reasons first as It's an expensive treatment. I'm willing to bet they didn't carry it out properly either. In simple terms, the guy should have spent about 4 hours with you, treating each rad in turn. There would have been some banging of each rad to dislodge sludge. Usually British Gas engineers just plug the equipment in and sit down for 3 hours.
