7.2 Preliminary work for
incremental heating test
Carry out an incremental heating test to check
the correct function of the surface temperature
balance.
NOTICE
Damage to the screed as a re-
sult of incorrect temperatures!
f Carry out incremental heating tests
of concrete and calcium sulphate
screed according to DIN EN 1264-
4.
f Observe the instructions
of the screed manufacturer.
f Adapt the flow temperature to the
surface temperature balance.
f Do not exceed the screed tem-
peratures near the heating pipes
specified as per DIN EN 1264-4.
Apply screed suitable for heating systems after
plastering.
Start the incremental heating test at the earli-
est:
• 21 days after laying of concrete screed
• 7 days after laying of calcium sulphate
screed
