This Recoheat Airflow Heat Recovery flue insert is adjustable with a minimum height of 410mmm and maximum 480mm or 500mm at a pinch. We supply the system with 1 metre of heat-resistant black silicone tube, and 3 metres of standard tubing, plus connectors to the 60lpm pump.
When you're checking out, please make sure you select the colour Black or Silver, which is actually plain steel: you need to click on the Black option even though it looks as if it's pre-selected.
The Recoheat is a heat pump for wood burners and solid fuel stoves. It significantly increases the heat output of your stove and how long the stove delivers heat for, and reduces your fuel consumption - all at the cost of running the air pump - so similar to the cost of a light bulb.
Please check your flue size carefully - this is the 6" version: 5" versions are also available.
