Review of Charnwood C 5 stove

Charnwood 5 woodburner

Ever since start up the stove has burned too much wood, even with the single damper control pushed fully in.

Stove expert replied: You say that you are burning too much wood - by this do you mean that the stove is working hard, with vigorous flames continuously but not producing much heat? This seems opposite to the dirty glass that is being experienced, one indicative of an over drawing flue the other being lack of air for complete combustion and or wet fuel. Received from the manufacturer the following information: The reasons why the glass is blackening up can be various. - The C-Five is a DEFRA exempted appliance, therefore it is designed to not shut down fully. But as not everybody live in a smokeless zone, we gave the option to unscrew the stopping device so that the rod could close a bit more. But pushing the rod fully in will shut down all air vents, and as a result no air feed for the combustion, the stove "suffocates", creates creosote and suits up the appliance. - logs been slightly too damp still. An easy test would be to buy a bag of compressed log briquettes (less that 10% humidity), and make a test. - A lack of draught in the chimney/flue will slow down the oxygen feed to the fuel, resulting in it to not burn correctly. - A house that is too airtight will reduce the feeding of oxygen too. You can fit an external air kit that will take the air from the outside world. The heat output of the stove will be affected, of course, by the lack of combustion of the fuel.
