Baxi Multifit IFOS Weather Compensation Kit for Combi Boilers

The Baxi Multifit IFOS Weather Compensation Kit provides a simple and cost-effective way to add weather compensation to compatible Baxi and Potterton combi boilers. Designed for straightforward installation, the in-flue outdoor sensor detects external weather conditions and allows the boiler to automatically adjust its operation to maintain efficient performance. By responding to changes in outdoor temperature, the system can help the boiler operate more efficiently and may help reduce unnecessary energy use and heating costs.

Simple In-Flue Weather Compensation

Unlike conventional outdoor sensors that require a separate sensor to be mounted on an external wall, the IFOS sensor clips directly onto the air duct of the flue terminal. This keeps the installation neat while allowing the sensor to detect the surrounding outdoor temperature. Air flows freely over the sensor, helping provide more accurate temperature readings so the boiler can respond appropriately to changing weather conditions.

Quick and Easy Installation

The kit has been designed with installers in mind and requires minimal components. The sensor connects back to the boiler using a simple two-wire cable, which runs down the flue air duct. This means there is no need for drilling through external walls or carrying out unnecessary disruption during installation. The kit now includes sensor clips for both horizontal and vertical flue terminals, providing greater flexibility for different boiler installations.

Comfort Accessory Included

A comfort accessory is also included, giving users the option of having hotter radiators when required. This provides additional control over heating comfort while retaining the benefits of the weather compensation system.

Efficient and Practical Design

The IFOS kit uses very few components, making it a straightforward alternative to more complex external weather sensors. Its discreet in-flue design keeps the sensor neatly positioned within the flue terminal while allowing it to accurately monitor outdoor conditions.
