Inserts are built into( under) a chimney , that is why they are called insert.
They are less efficient than a wood burning stove , that is in front of the chimney and connected to it by a pipe.

The inserts were modern in the seventies and eighties. Now that everybody has a nice huge flatscreen tv in the living room, these inserts are not too popular anymore. Two is a crowd. The modern wood stove is more efficient. Metal work, step by step: (1), (2), (3) |

Seeing the above post makes me think of the mistakes I made during our time at both our places before radically downsizing.

Great, a link to a discontinued item. Try this one instead. |

Does a flue for a wood burner need to reach a certain height in France? ie it cant just exit a wall at ground floor stove height and terminate there? No it can't , your stove wouldn't work either.
The pipe needs to be 40cm higher than the top of your roof , to get a good draw and be within the law.
Watch out , if you don't get it done by an acredited company , your insurance will not be valid . You don't have a chimney ?
We do have a chimney, one of the channels is used for the oil boiler flue, I have no idea if there is another channel as its all buried behind brick/stone etc, also its not necessarily where we want the log burner..... |

That would be the easiest solution , just pull a pipe down the chimney and connect your wood stove. Otherwise you will have to put in a complete new pipe to the top of the house .

stove fans on top (that generate their own electricity from the heat of the stove Do they actually generate electricity and use that to power the fans or do the fans rotate through the current of hot air? Looking at the image in the link with the heatsink I can't make my mind up which it is, if they do indeed convert heat into electricity and electricity into rotary motion then how do they do the first part? |

And I quote,"The Peltier device generates electricity by having one side hot and the other side cooler (known as a 'thermal difference'). This temperature difference creates a 'potential difference' (a voltage) in the circuit. This voltage powers the motor, which in turn drives the fan." |

Looking at the image in the link with the heatsink I can't make my mind up which it is, if they do indeed convert heat into electricity and electricity into rotary motion then how do they do the first part? Hi PCPA the original stove fans were powered by a small sterling piston engine but it took a lot of heat from the stove to get it moving and as dust would settle on it over time would slow down the moving parts. We have had the heat powered fans for some years now (we currently have 5), even places like Lidl sell them for €20-30 from time to time. I was always told it was a bi-metal reaction that generated the power, two different types of metal reacting differently when heated. |

It is called an Evergreen Holly stove, I don't think you can get it anymore, about 15 years ago I bought 3 of them over a year long period as I was so impressed, I paid between £399-£499 for them, I recently took one out of our holiday rental in Brittany (and I replaced it with an electric one and sealed the fireplace), I put it on Ebay last October and sold it on the auction for £520. www.debraefireplaces.co.uk/fireplaces.asp?s=stoves&t=MULTIFUEL%20STOVESIf that does not bring up the picture Google Evergreen Holly cast iron stove.# |

Did you have to push start the Stirling engine each time?
