The course covers:

Benefits of the Unvented Hot Water Course:

With this course you can install Unvented Hot Water Systems with a capacity up to 500 litres and 45kW power input. As well as this you will understand how to design safe systems around Unvented Cylinders, fault finding, and the maintenance involved in the industry.

Perfect for plumbers looking to up skill and progress in industry. We also highly recommend this if you are planning and getting into the renewables sector and Heat Pump installing.

This means

  • Great next step for Gas Engineers and Plumbers
  • Creates a new sector of revenue for qualified trade people
  • Great add on when moving into the renewables sector
  • Allows you to work on G3 Unvented Cylinders

System & Safety Requirements & Qualifications:

Put simply, you need no formal qualifications to undertake the course unless you are planning on becoming Microgeneration Certification Scheme (MCS) registered. If this IS something you are interested in; candidates should already be experienced in installing domestic cold and hot water systems. Heating engineers should hold a competency in a conventional fuel i.e. gas, oil or solid fuel, recognised by the Department for Communities and Local Government (DCLG). Plumbers need to hold the equivalent of an NVQ Level 2. Basic knowledge of the WRAS Water Regulations is also desirable but not required for all candidates.

To find out what this means for you, please get in touch with us at 0800 6123177.

Unvented Hot Water Training Location:

This Course is based in our Halifax Training centre located close to the M62 with great access from all over the country.

Our purpose built centre offers state of the art classrooms and workshops where you can put into practice the principles you will learn about, getting in-centre experience working on actual boilers and appliances. Our facilities have multiple unvented cylinders plumbed in so trainees can gain an understanding of the systems in situ.

We find our students love our facilities so much they are one of the main reasons they keep coming back for further training.

To start the Hot Water Systems & Safety course you only require prerequisites if you are wanting to become Microgeneration Certification Scheme (MCS) registered. If this is the case candidates should already be experienced in the installation of domestic cold and hot water systems. Heating engineers hold competency in a conventional fluid recognised by the DCLG. Plumbers need to hold the equivalent of an NVQ Level 2.

Of course, you will just need to enter their details above or when you get in touch with us. We will require to speak to the individual trainee(s) before the course starts to complete our informal assessment.

You don’t need anything to start the course. All we recommend is you bring some steel toe-cap boots and work trousers as there is a small practical element to the Unvented (HWSS) course.

This course is not an extension of scope and will not change/increase your ACS qualification codes. It is a stand alone qualification which enables the installation and servicing of G3 unvented cylinders.

Just recently completed a fault finding course with the ever knowledgeable Roy Fugler.I honestly cannot rate this training centre and Roy highly enough!I completed my ACS training with them over two years ago and they were my number one choice when I decided to expand my knowledge around the inner workings of a boiler and how to diagnose the issues that often arise.I will have to re-sit my ACS again in a few years and there’s only one place I’ll be going. It’s VIVA all the way!
