Baxi Multifit In Flue Outdoor Sensor - Ridge Tile (IFOS)
Optimise boiler efficiency and comfort with the Baxi Multifit In Flue Outdoor Sensor - Ridge Tile, a smart weather compensation solution designed specifically for Baxi and Potterton boilers. This discreet IFOS kit fits directly into the ridge tile flue terminal, allowing the boiler to automatically adjust its flow temperature according to outdoor conditions for lower running costs, improved energy efficiency, and full compliance with current UK building and Boiler Plus regulations.
Why buy?
Installing the Baxi Multifit In Flue Outdoor Sensor helps reduce your annual heating bills by fine tuning the boiler’s output to match the outside temperature, so your home stays comfortable without over running. The sensor is pre installed in the ridge tile terminal, so you avoid drilling through walls, messy external cabling, and additional work at height, saving time and minimising disruption on new build or retrofit projects.
The kit also includes a comfort accessory that allows you to raise radiator temperatures when a higher level of comfort is required, giving you flexible control over your heating system. With few parts and a simple two wire connection routed through the flue air duct, this is one of the most straightforward weather compensation solutions on the market, ideal for both homeowners seeking efficiency and trade installers completing compliant installations.
Suitable for
This IFOS kit is suitable for use with a range of Baxi Assure and Potterton system and combi boilers that require outdoor temperature compensation to meet Building Regulations and Boiler Plus requirements. It is specifically designed for installations where the flue terminates in a ridge tile or vertical flue termination kit, and works just as effectively on horizontal flue systems up to approximately 4 metres in length, or up to 5 metres when combined with an optional extension cable.
The sensor is ideal for:
- Domestic properties seeking weather compensation control.
- New build housing developments where SAP related efficiency benefits are required.
- Homeowners who want more responsive, efficient heating without visible external sensor units.
- Professional installers looking for a quick, code compliant weather compensation solution.
Key features
- Pre fitted in flue outdoor sensor (IFOS) within the Baxi Multifit ridge tile terminal kit for neat, out of sight installation.
- Weather compensation control that automatically adjusts boiler flow temperature based on outdoor temperature, helping to reduce energy consumption and lower gas bills.
- Comfort accessory included to allow higher radiator temperatures when greater warmth is needed.
- Sensor sits under the air duct of the flue terminal, protected from direct sunlight so there is no need to position the flue on a north or north west facing wall.
- Free flow air design delivers accurate outdoor temperature sensing for more stable and efficient boiler operation.
- Simple two wire cable connection routed down the flue air duct, eliminating the need for drilling or external wiring.
- Minimal parts and straightforward installation, reducing job time and complexity for professional installers.
- Helps meet UK Boiler Plus and Building Regulations requirements on new and replacement boiler installations.
