Master and Slave Fan Convector Units

What is a fan convector?

Fan convectors have for many years been acknowledged to be one of the simplest and most cost-effective ways of heating a room quickly with the added benefit of subtle air ventilation. With minimal maintenance requirements, fan convectors rapidly distribute heat throughout a room whilst occupying much less wall space than a radiator of equivalent output. That's what makes our Forceflow Fan Convectors such a popular choice, when it comes to heating and ventilation.


There are many benefits for choosing to use a fan convector unit for your HVAC requirements. Some of these advantages include:

Better Connectivity

Our expert designers are always looking for new ways to improve the efficiency and cost effectiveness of our units. That’s why we have designed a system that allows multiple fan convector units to be connected, with only the need for one unit to house controls. This way you can have units located across your room, all working together for heating and a ventilation system.

Saves Time and Energy

Nobody wants to enter a building and then travel around clicking on each fan convector unit one at a time, checking they are at the correct settings. Linking units together puts a stop to this. As only one unit has the control, it isn’t possible for someone to lower the temperature on one unit and make the other units work harder – as soon as the master unit is switched on, so are all the others.

Linked fan convector units

So why not ask our teams about connecting your units together, saving you time and energy?
