With climate change and extreme weather variations

becoming increasingly common, and with very cold winters

with temperatures as low as -20°C being experienced,

practices such as externally run condensate discharge

pipework are now being questioned.

In these conditions the condensate pipe on a condensing

oil-ﬁ red boiler can freeze. This can lead to a blocked

condensate pipe, which will cause condensate to drain

back into the boiler leading to corrosion of mild steel

components and leakage of condensate. This can result

in premature component failure, damage to property and

burner failure.

The CondenseSure auxiliary siphon has been designed to

allow a more ﬂ exible approach to boiler siting.

Tested to extreme temperatures

The CondenseSure auxiliary 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

Most oil-ﬁ red condensing boilers have a trap which

releases condensate as it is formed. A typical A-rated

condensing boiler will generate up to 2 litres of

condensate an hour (dependent on output and

temperature) which is discharged as a continuous

trickle. With this frequency of discharge, the condensate

pipework is never 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 Worcester CondenseSure

The CondenseSure

insulating jacket

helps to retain the

temperature of the

condensate.

Features Benefits

No power consumption

No electrical wiring

connection or supply needed,

meaning zero running costs

No moving parts No failure of components

Can be installed on new or

existing installations

Suitable for any gas- or

oil-fired condensing boilers

Can be attached to 22mm

heating flow pipework

(gas-fired boiler)

Uses ‘free’ energy from the

pipe to heat the condensate

Under boiler or remote

installation

Flexibility

No electrical connections No electrician needed

No pipe insulation needed

Cost saving and aesthetically

pleasing

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.

CondenseSure can easily be ﬁ tted to an existing

condensing boiler to provide peace of mind in extreme

weather conditions.
