Worcester Condensure Siphon

Worcester CondenseSure Siphon

The Worcester CondenseSure Siphon (Part No. 7716192746) is a clever, passive condensate management device designed to stop condensate pipes from freezing during cold weather. Suitable for all gas and oil-fired condensing boilers, including the entire Worcester Greenstar range, it provides a simple yet highly effective way to keep your heating system running smoothly even in harsh winter conditions. Unlike traditional solutions, CondenseSure requires no electrical power, has no moving parts, and doesn’t rely on external pipe insulation. Instead, it uses a smart siphon design that attaches directly to the 22mm flow pipework. By harnessing the natural residual heat from the boiler, it gently warms the condensate and ensures it continues to flow and discharge correctly — even in freezing weather. Installation is flexible too. The unit can be fitted neatly under the boiler or wall-mounted elsewhere, making it suitable for a wide range of boiler setups. Having been tested to withstand temperatures as low as –15°C for sustained periods, CondenseSure offers reliable protection and complete peace of mind during the coldest months.

FAQs

Do I still need to insulate my condensate pipe if I use CondenseSure?

No — the CondenseSure Siphon eliminates the need for external pipe insulation by warming the condensate naturally using heat from the boiler’s flow pipework.

Does the CondenseSure Siphon require electricity to operate?

No — it is a fully passive device with no electrical connections or running costs, making it highly reliable and maintenance-free.

Is the CondenseSure compatible with my Worcester Bosch boiler?

Yes — it works with all Worcester Greenstar boilers, as well as other gas- and oil-fired condensing models. Always check with your installer to confirm suitability for your specific setup.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
