The Boiler Buoy Condensate Bypass Valve is an inexpensive and simple to install, easy to use solution to the costly problem of external condensate pipes freezing in very cold weather.

The Boiler Buoy eliminates the need for expensive call-out costs and possible damage to your boiler – not to mention being without heating at the very time it’s needed most.

During recent winters the UK has experienced prolonged spells of extremely cold weather – down to minus 20oC and below in many areas. This resulted in a significant increase in the number of calls to boiler manufacturers and heating engineers from householders with condensing (high efficiency) boilers where the condensate drainage pipe had frozen and become blocked with ice, causing the boiler to shut down. In the vast majority of cases such problems occur where the condensate drainage pipe is located externally to the building for some part of its length.
