Course overview – summary of sessions
This course is split into 9 sessions:
• Today’s session, Session A, introduces you to the course.
• Sessions 1 to 6 cover core learning.
• Sessions B and C focus upon revision.
• Session D is the final multiple choice assessment.
To complete the course you are expected to attend every
session, with every session giving valuable learning to help
you in work and to prepare for the end of course assessment.
Sessions will include a mix of activities including listening,
research and self-assessment exercises.

Session A – course introduction
Course overview – revision and assessment
The course will finish with a multiple choice assessment.
To prepare you for this session two essential interactive revision focused
sessions will reflect on your learning throughout the course and help you to
assess and address areas of knowledge and types of calculations that you need
particular help with.
Session B This session will:
• explain the purpose and structure of the end of course assessment
• review core learning from all course sessions
Session C This session will include practice multiple choice questions and
further revision.
Session D The end of course assessment will be completed during this session.

Session A – course introduction
Self assessment exercise
Students should work individually to complete the self
assessment exercise.
Answers are shown on the following slides.
The purpose of this activity is to help you and your tutor see
what knowledge you have at the start of the course.
It is expected that students will be starting with a range of
knowledge.

Solutions
Question 1
Solar, heat pumps and biomass are the 3 renewable
technologies most commonly used in UK domestic heating
and water (in 2013).
Questions 2 and 3
It is expected that students will be starting with a range of
experience, qualifications and training and may learn from
each other through informal and formal discussions as you
progress through the course.

Question 4
If you replace a conventional gas fired boiler in a domestic style
property built since 1 April 2005 you would normally install a
condensing boiler.
Question 5
You would not usually install an immersion heater in a house
with a combination boiler, although a separate hot water storage
tank and immersion may be installed in certain circumstances
e.g. with solar water heating.

Question 6
An oil boiler should be maintained by somehow who is OFTEC
registered.
Question 7
In dwellings with a total usable floor area up to 150m2 should
be divided into at least two space heating zones with
independent temperature control, one of which is assigned to
the living area

Question 8
Vented copper hot water cylinders should comply with BS
1566: 2002 part 1.
Question 9
According to the “Domestic Building Services Compliance
Guide” an oil combination boiler installed in a new dwelling
should have an (2009 SEDBUK) efficiency not less than 88%.
Question 10
A boiler interlock can improve efficiency by preventing the
pump from running and the boiler from firing when there is no
demand for heating or hot water.

Question 11
An acceptable position for a boiler terminal according to the
“Guide to condensing boiler assessment procedure for
dwellings” would be a flue terminal (not a vertical flue pipe)
visible from the front of the building.
The following would not be acceptable positions for a boiler
terminal:
• A wall terminal that discharges under the roof of a car port
• A wall terminal less than 2.1m above the ground that
discharges across a public footpath
• A flue that passes through another dwelling, another building
in different ownership or another fire compartment

fully pumped.
Replacement gas or oil fired heating and hot water systems
should be fully pumped.
The system should be converted to fully pumped when
replacing gas or oil fired heating boilers.
