Additional Features
A unique and patented corrosion resistant
stainless steel condensate heat exchanger.
Integral sensors (NTC) for monitoring flow
and return water temperatures.
3 way switching valve and facilities for
connection to an eco hometec DHW storage
module or similar.

4. Description
of
Appliances
4.1
EC 25 H Compact
The ‘H’ model is suitable for a central
heating system with hot water and heating
circuit(s) controlled using two or more zone
valves.
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 32 to
100%, while the maximum capacity can be
set and adapted to the capacity of the CH
system.
4.2
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.
4.3
EC EC 25S Compact
This unit has a built-in heat primary heat
exchanger and hot water production is
continuous.
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. The S (combi) range of eco
hometec boilers are all solar compatible and
can be installed directly as part of a solar
heating and hot water system. If you would
like more information on the eco hometec
solar heating systems and equipment
please call or e.mail or sales department.
All appliances are designed for sealed
system installation only and require a
suitably sized expansion vessel fitting to the
system.
