The following training and assessment packages are certificated by Logic Certification Ltd to industry led standards

Title Content type
Code: HSD1
Expiry: 5 years
Guided Learning Hours: 2 - 3 days

The Foundation certificate in heating and hot water design course is aimed at installers who have recently entered the industry or have little or no experience in the area of heating system design. The course is particularly useful for candidates moving in to the renewables industry, in particular the  installation of ground and air source heat pumps, or for underfloor heating industry where accurate heat loss calculations are of paramount importance.

The course will provide a good level of understanding for the design and specification of basic domestic heating systems, as well as size hot water storage cylinders. In addition, heating and hot water design will act as a stepping stone for operatives who wish to go on and complete the IDHEE full diploma. The course is accepted by IDHEE as a unit credit and will save two days attendance on the full diploma course.

The course is based upon the CIBSE Domestic Heating Design Guide (DHDG) 2007 ISBN 1 903287 40 5

Learners will:

Be trained and assessed in the following areas:

  • Comfort conditions and basic heating and hot water principles
  • Basic system types
  • Heat-loss calculations
  • System design
  • System specification and selection including emitters, pipe work, boilers and pump sizing
  • Sizing and selection of hot water systems

While training covers pipe-sizing and pump-settings etc in theory, they are not part of the practical work. There are questions regarding these in the written assessment. Candidates wishing to progress to more advanced levels should apply for the IDHEE diploma course.



Learners should have basic knowledge in the installation of heating and hot water systems.
