8.2 EC 25HS Compact
The ‘HS’ range are higher specification.
With its 4 x 15mm connections it offers a
low temperature output, typically 55
O
C, for
under-floor heating or a fixed/variable
temperature output for connection to
radiators.

Despite the low boiler flow
temperatures feature ALL low temperature
under floor installations require an
obligatory mixing valve or high temperature
cut out thermostat installing as part of the
system controls.
Flow temperature to hot water cylinder can
be set as required (max. 85
O
C)
The unit has a variable capacity of 32 to
100%, while the maximum capacity can be
set and adapted to the capacity of the CH
system.
Hot water cylinders must be double feed
indirect and to aid efficiency and fast
recovery times (all appliances are hot water
priority) should be of the high recovery type.
Recommended minimum coil capacity
25kW.
