The Worcester Condensesure Siphon - Bosch WORCESTER Greenstar CDi Classic Series Technical Information

The Worcester
CondenseSure siphon
With temperatures as low as -20ºC being experienced
in very cold winters, practices such as externally run
condensate discharge pipework are now being questioned.
The Worcester CondenseSure siphon has been designed to
allow a more flexible approach to boiler siting.
Tested to extreme temperatures
The Worcester CondenseSure siphon has been extensively
tested under simulated extreme weather conditions, proving
its effectiveness in preventing frozen condensate at -15ºC
for a sustained period of 48 hours.
CondenseSure principle of operation
Within most condensing boilers, there is an internal siphon
which holds around 100ml of condensate before being
released down the condensate discharge pipe. A typical
high-effi ciency condensing boiler will generate up to 2
litres of condensate an hour (dependant on output and
temperature) and this will result in the in-built siphon
discharging approximately every 3 minutes. With this
frequency of discharge, it is unlikely that the condensate
pipework is ever empty of condensate, consequently
increasing the potential for freezing of the pipework in
prolonged sub-zero temperatures.
The CondenseSure siphon connects to the boiler
condensate discharge outlet and collects the condensate
into a larger volume before releasing it into the
discharge pipe.
With this expanded siphonic operation, the discharge from
the CondenseSure increases to every 15 to 20 minutes,
resulting in:
•
Increased velocity and fl ow rate
•
Only 3 to 4 siphonic actions per hour, meaning the
condensate pipework is empty for longer
•
Signifi cantly decreased or even eliminated
freezing potential.

The CondenseSure insulating jacket helps to retain the temperature
of the condensate.
A universal fi tting for new and existing installations
Although developed specifi cally for Worcester Greenstar
gas- and oil-fi red boilers, the Worcester CondenseSure
can also be fi tted to any make of condensing boiler for
both new and retrofi t installations. The CondenseSure
can provide a simple solution which eliminates the need
for re-siting both the new boiler and the system pipework
when replacing an existing non-condensing appliance. The
CondenseSure can easily be fi tted to existing installations
to provide peace of mind in extreme weather conditions.
