The only saving grace with Kestons is that they have one of the most helpful helpdesks I've encountered. A helpful helpdesk??? Some irony in there somewhere!!
Are you sure? I found them useless but this was Ideal that I spoke to so not sure how long they had taken them over for. All I asked was does the heat exchanger come with all gaskets etc needed for fitting. The answer was yes. The real answer was no not a thing just a heat exchanger.
