Appliances
9.1
EC 16,23,31 and 38 H
The ‘H’ model is suitable for a central
heating system with hot water output
controlled using a 3 way divertor valve
(spring return to heating).
The appliance produces a low temperature
output for under-floor heating or a
fixed/variable temperature output for
connection to radiators. Flow temperature
to hot water cylinder can be set as required
(max. 85
O
C)
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.
The unit has a variable capacity of 20 to
100%, while the maximum capacity can be
set and adapted to the capacity of the CH
system.
9.2
EC 16,23,31 and 38 HS
The ‘HS’ range are higher specification.
With its 4 x 22mm 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.
Dsspite the low boiler flow
temperatures feature ALL low temperature
under floor installations require an
obligatory mixing valve 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 20 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.
9.3
EC 16,23,31 and 38 S
This unit has a built-in heat primary heat
exchanger and Hot water production is
continuous.
The unit has a variable capacity of 20 to
100%, while the maximum capacity can be
set and adapted to the capacity of the CH
system.
EC38S Combi with integral 10Litre store
This appliance requires an expansion
vessel and a 3 bar pressure relied valve
fitting to the system
