“I haven’t had Rational out to descale the steam ovens since we re-opened, we used to have to call them every month to do a full descale so the system is working really well. The dishwashers are also all keeping free from scale. I have noticed a difference in the limescale build-up, it’s virtually non-existent since installing the technology. They have caused a few leaks though, where the limescale has been eaten away round joints and valves, but that was to be expected and is a good thing because it identified issues we would never have seen and enabled us to repair them before they caused too much damage.”
