Outdoor water piping insulation
NOTICE
Outside piping. Make sure the outside piping is insulated
as instructed to protect against hazards.
For piping in free air, it is recommended to use the insulation
thickness as shown in below table as a minimum (with λ=0.039 W/
mK).
Piping length (m)
<20
20~30
30~40
40~50
For other cases the minimum insulation thickness can be determined
using the Hydronic Piping Calculation tool.
The Hydronic Piping Calculation tool also calculates the maximum
hydronic piping length from the indoor unit to the outdoor unit based
on the emitter pressure drop or the other way around.
The Hydronic Piping Calculation tool is part of the Heating Solutions
Navigator which can
professional.standbyme.daikin.eu.
Please contact your dealer if you have no access to Heating
Solutions Navigator.
This recommendation ensures good operation of the unit, however,
local regulations may differ and shall be followed.
