his Recoheat Airflow Heat Recovery System is built to fit 6" stove flues with insulated twinwall flue pipes. It has extended inlet and outlet pipes so that the unit can be fitted with a cover to form a continuous line of flue. The cover, which must be sourced from your flue supplier, can then be drilled to allow the inlet and outlet pipes to pass through and connected up as normal.
Please note that we don't supply the units pre-fitted with twinwall because all the manufacturers have different connecting methods, so they're incompatible with each other. Our unit fits into the stove collar and the spigot of your twinwall flue will fit into this, with a cover as described.
The unit is supplied with a super-silent aquarium pump with an air flow rate of 3600 litres per hour (60l/m), 1 metre of heat-resistant black silicone tube, and 3 metres of standard tubing, plus connectors.
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 37-watt air pump - so similar to the cost of a light bulb.
Please check your flue size carefully - this is the 6" twinwall version for insulated flues: a 5" twinwall version is available.
