Hot Water Systems and Safety (Unvented Cylinders) Course
Skills Training Group’s Hot Water Systems and Safety (HWSS) course supersedes the unvented cylinders course and now covers all hot water systems.
The HWSS curriculum has been updated due to the G3 Building Regulation being revised. The HWSS course includes content from the old qualification as well as new content from the new HWSS course.
Very positive feedback from all staff who were on the training, great trainers and they made the topic interesting and easy to understand.
Frequently Asked Questions
What is an unvented hot water system?
An unvented hot water system has no cold water feed tank, instead relying on direct mains pressure to operate a sealed (unvented) hot water cylinder. The unvented cylinder maintains pressure from an incoming water supply.
Because unvented systems are "sealed/closed," they need additional equipment, such as an expansion vessel, to manage the pressure fluctuations within the system as the water inside heats up.
What are the benefits of an unvented system?
Because there is no need for a separate cold water feed tank — and the piping that connects the tank to the cylinder — it takes less room. This also means they are easier and faster to install in a big commercial system.
The pressure in an unvented system is derived from the mains feed, which means it's usually greater. This means that with an unvented system, the outlet pressure is superior and taps and showers function more effectively.
What is an unvented cylinder course?
An unvented cylinder course is a training program for heating engineers who want to expand their knowledge and skills in hot water systems. The course covers a range of topics about hot water storage and systems for storing hot water at home. The focus is on important parts of hot water systems, like safety controls and hot water expansion.
Who is the hot water storage systems course for?
The hot water storage systems course is ideal for plumbing professionals who want to specialise in hot water systems. It teaches in-depth knowledge and practical skills in hot water storage systems, as well as how to properly install and maintain domestic hot water storage systems.
Who can undertake the hot water cylinders course?
Candidates must either have an ACS certificate, hold a formal qualification in plumbing, or have a trade qualification in conventional heating engineering to enroll in the course. Successful candidates will receive a certificate of competence recognised by the Building Control department and the Department for Communities and Local Government.
