Glow-Worm 20040796 Outdoor Sensor

Product Type

Product Description

The Glow-worm Outdoor Sensor provides an added level of intelligence to the central heating system by monitoring the external temperature to the home and adjusting the heating output to better maintain the ideal internal temperature. The weather compensation allows the outdoor temperature to be communicated back to the central heating system and adjusting the flow temperature to the radiators to meet the users heating demands. The Outdoor Sensor can significantly help users to reduce their boilers fuel consumption by ensuring that the home is not over heated when the outside temperature increases and affects the internal temperature of the home. This ensures that low annual gas bills are maintained and the homes carbon emissions are reduced.

  • Simple and discreet


At Boilers2go we recommend the Glow-worm Outdoor Sensor for use with all Glow-worm gas boiler models for increased energy efficiency and reduced gas bills and carbon emissions. Plus with the Outdoor Sensor the homes desired central heating requirements can be better maintained for improved comfort.
