Underfloor Heating System
Start-up & Pre-Commissioning
Procedure
Issue 2 - Jan 2005
With reference to British Standard EN 1264 and CIBSE Recommendations
BS EN 1264 requires the leak test and initial heat up to be recorded and documented. This form is
designed for this purpose and will also act as quality checking devise to assist in any future queries.

B. Testing for leaks
All heating pipe circuits of the underfloor system are to be hydraulically wet tested for water leaks
before screeding is allowed to commence (BSEN 1264 :part 4 Para 4.3).
Testing should be completed in 2 stages. Firstly at 2 Bar for 10 minutes following by 10 Bar for a further
10 minutes. This testing, combined with visual and other relevant checks, should reveal installation
problems and is regarded as good plumbing practice.
It is important that all pipe circuits remain under pressure (normally 3-6 bar) during the screed laying
and curing process and every effort should be made to protect the pipework from damage
(BSEN1264 Part 4 Para 4.3).

Were any leaks present ? (if yes, please state action taken)
C. Heating-Up Conditions of the Floor Heating System (EN 1264 Part 4, Para 4.4)
This function has to be carried out on all heated floors. For Solid Floors with Cement screeds this must wait
until 21 days have elapsed after the screed has been laid. In the case of Anhydrite or Calcium Sulphate
screeds the elapsed time shall be only 7 days from the date of laying.
(Confirm this using the screed manufacturers’ information).

Check manufacturers’ specifications for information,
which could affect the maximum temperature
(e.g. for floating floors etc).
