Exhausto chimney fans are useful in certain situations where it just isn't possible to get a good enough draw on a chimney to make the fireplace or stove work properly. Commonly this is to do with chimney height, but there are also other factors that aren't easily remedied.
So when all else fails the solution is an
Exhausto Chimney Fan. These robust units are easily fitted to the top of the chimney with a set of controls positioned near the stove or fire that allow the fan to be adjusted to the desired speed.
There are two types of Exhausto Fan:

the RSV range, which comes in five different sizes and the RS range, which comes in six different sizes.
The Exhausto fans can be used with gas, oil or solid fuel appliances and can withstand continuous flue gas temperatures of up to 250*C. They are hinged to provide easy access for maintenance and come with a two year warranty.
To decide exactly which fan is needed for your chimney all you have to do is fill out the
appraisal form and email, fax or post it to us (you can find our contact details on our
contact page) and we will come straight back with all the information you need. You will then be able to choose which type of control you would like for your exhausto fan.
Exhausto Fan Electronic Speed Controls
The two main types of control used for the Exhausto Chimney Fans are the EFC 16, which turns the unit on and off and gives you infinite variation of the fan speed, and the temperature sensitive EFC 18, which will start when it detects temperatures over 40* C and stop when the fire goes out.
All controls carry the two year warranty.
