The purpose of this installer training is to give candidates an entry level qualification to build upon current heating or plumbing trade knowledge in order to extend their work scope to include the installation of Solar Thermal Domestic Hot Water Systems.

  • Duration: 4 Days
  • Accreditation: Logic
  • Cost: £795 +VAT
  • Entry Requirements: Plumbers with relevant certification and experience; Hot Water Systems & Safety , Water Regulations/Water Byelaws, Energy Efficiency for Domestic Heating
  • Course Type: Classroom / Practical

This solar thermal installer course covers the predominant North European fluid filled, indirect heating systems. The course does not cover all possible variants of this subject and in many cases the support and guidance of the manufacturer would be required upon fitting the equipment. The course covers the following main types of system collector types:

  • Fully filled sealed solar thermal systems
  • Drain back solar thermal systems
  • Flat plate solar thermal collector
  • Evacuated tube solar thermal collector
  • Direct flow evacuated tube solar thermal collector

Course Outline

Whilst this course is aimed at practicing heating or plumbing operatives, it may also be of benefit to building service engineers, designers, structural engineers, energy solution consultants and architects. The full qualification will only apply to candidates who meet the requirements of the awarding bodies accreditation scheme. The course will cover the following topics:

  • Market insight and background to solar thermal
  • Regulations and Standards
  • Solar heated storage types (storage cylinders)
  • Solar primary system types
  • Basic system design and integration
  • External and Internal site survey, Installation methods and materials
  • Filling and commissioning

Note this course does not include roof work in detail but does cover the legislative requirements and working at height requirements.


The final assessment for the course is in the form of a written assessment. There is also a practical assessment associated with this certification.

Candidate Entry Requirements

It is essential that the candidate is experienced in the installation of domestic hot and cold water systems and will hold a G3 certificate in Unvented Hot Water Systems. It is also essential that the trainee holds one recognised competency in a conventional fuels i.e. gas, oil, or solid fuel: or for those in the plumbing field with and NVQ 2 or equivalent and/or experience. Experience in basic electrical practice would also be desirable. A basic knowledge of the water (fittings) regulations is also desirable, as is a current WRAS certificate.

Candidates should note that if they do not possess either, both the G3 Unvented and WRAS and Energy Efficiency courses can be completed at Narec Distributed Energy.
