The Worcester Condensesure Auxiliary Siphon - Worcester Greenstar 12Ri Technical Information

The Worcester CondenseSure
auxiliary siphon
With climate change and extreme weather variations
becoming increasingly common, and very cold winters with
temperatures as low as -20°C being experienced, practices
such as externally run condensate discharge pipework are
now being questioned.
The CondenseSure auxiliary siphon has been designed to
allow a more flexible approach to boiler siting.
Tested to extreme temperatures
The CondenseSure has been extensively tested under
simulated extreme weather conditions and proved 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 efficiency 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 is every 15 to 20 minutes, resulting in:
•
Increased velocity and flow rate
•
With only 3 to 4 siphonic actions per hour,
the condensate pipework is empty for longer
•
Significantly decreased or even eliminated
freezing potential.

The CondenseSure insulating jacket helps to retain the temperature
of the condensate.
A universal fitting for new and existing installations
Although developed specifically for Worcester Greenstar
gas- and oil-fired boilers, the Worcester CondenseSure
has the added advantage of being able to be fitted to
any make of condensing boiler for both new and retrofit
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 fitted to existing installations to provide peace of
mind in extreme weather conditions.
