Boiler & Cylinder Installations

If you notice water dripping or running into the tundish from your unvented hot water cylinder, it’s not a random fault — it’s a safety device doing something for a reason. In this video, we explain how to correctly diagnose the real cause of tundish discharge on an unvented system. In most cases, the problem will be one of the following: • A failed or flat expansion vessel• A faulty or passing pressure relief valve (PRV)• A lifting temperature and pressure relief valve (TPRV) Each of these faults has a different root cause, a different test method, and a different repair process. Simply changing valves without proper diagnosis often leads to repeat failures and unnecessary costs. We also explain why tundish discharge should never be ignored, and why unvented hot water systems must only be worked on by G3-qualified engineers under UK Building Regulations.

How to Convert a Vented Hot Water Cylinder to a Mains-Pressurised Unvented System In this video, we show how a traditional vented cylinder is removed and replaced with a fully unvented, mains-pressure hot water system, including the installation of a digital programmer for accurate control, improved efficiency, and consistent hot water performance throughout the property. #hotwatercylinder #gasengineer #heatingengineer #plumber
