As pointed out a stirling engine fans and ecofans for wood burners are positioned on top of the wood burning stove and rely wholly on the heat from the wood burner stove to work.
Do wood burner fans work.
By now everyone who has a wood or multi fuel burning stove has heard of stove fans.
You know the handy fan that sits on your stove top or attaches to the flue pipe or even to the stove door and promises to distribute the hot air around your room and saves you money.
You don t need to connect to the electric power or buy batteries.
The heat differential between the base of the unit and the top of the fan drives the motor which in turn drives the blades around while the cooling fans at the rear help keep the top of the fan at a much lower temperature making sure the fan spins maintains constant revolutions.
Wood burning stoves have become trendy.
However you may still be on the fence about whether they genuinely work or if its just another one of those gimmicky gadgets that are a way of helping you spend your hard earned cash.
