Even when one tips it into a metal bin, it's better that the ashes should be at 200 than at 600 degrees C. The hotter the ash, the more volatile it is, so it will generate more dust whilst in transit to the bucket. Also, the hotter it is, and the more you tip into the metal bucket (especially when it is empty), the bucket itself can get hot enough to make melt/burn marks on the floor. My ash buckets have a double/false bottom - so are highly unlikely to char the floor. |

I am merely trying to record a balanced view in the discussion from my own experiences, & ISTR I have concurred on a number of aspects from other posters. .. Should you wish to stop reading this thread now then that is also *your* choice....;) Jim K |

My ash buckets have a double/false bottom - so are highly unlikely to char the floor. My bucket's bottom is held clear of the floor by 2-3cm by a rim. But the rim itself is just a continuation of the sides, and I'm concerned that heat conduction along this rim may suffice to melt the lino. |

Tim..- Hide quoted text - - Show quoted text - Thanks, and thanks everyone for the information in amost interesting thread. Does anyone have any experience of Stovax stoves, and the Sheraton in particular? This is the one I might have available for refurbishment. Can anyone suggest what would be a fair price to pay for one in used condition, needing a new top plate, for bricks and rope? With reasons for your price ;-) Cheers Richard |

Firelighters are seldom needed as a few sheets of scrunched up newspaper are usually enough to light dry logs - even oak. A local tree surgeon tells me that he is getting a good price for chipped wood at the moment because there is a shortage of wood for power stations to burn. I think he mentioned around £55 per tonne, collected from his storage field. John |

I have never used firelighters. If you build the fire right it will always catch from newspaper unless your wood is too damp. Friends have a dual fuel burner and when moving into the property was told it was very difficult to light. The chimney sweep told them that it was a common problem because the first time after being left without a fire for a lengthy period the metal flue liner (in a traditional chimney stack) was too cold and had more of a down-draft rather than an up-draft. He advised using firelighters for the first lighting. The advice was ignored at first and the fire was lit with newspaper, small dry sticks etc. and it refused to catch or stay alight for more than a few minutes. Firelighters were obtained and these kept the flames going long enough for the flue liner to heat up and then there was a transformation with air being drawn up through the system. Subsequent lightings were no problem probably because the latent heat from the brick chimney stack kept the flue warm enough. Mine is a Charnwood with a back boiler. You don't get as much heat directly into the room but it can supply hot water and power the central heating system too except in the coldest weather. The stove mentioned above did not heat water nor support CH but pushed out a great deal of heat when wood/coal consumption was high (air vents fully open and a roaring fire). Wood could not be stored beside the stove because after around an hour it started smoking! I suggest not an ideal heating method if you have small children around. You get a fair bit more power out of it when burning coal. To keep it going overnight it isn't a bad idea to put a couple of pieces of dense smokeless fuel in even when the grate is configured for burning wood. Mine quite often gets relit from the embers in the late afternoon. If coal was used overnight and the stove turned it down it could relight logs from the embers in the morning, if required. The stove (in a kitchen) is somewhat redundant now that oil CH has been installed. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

The only time it can be difficult to light is when the fire has been laid but not lit for weeks and then is needed on a particularly cold evening. Even so opening the door a crack usually gets it going. advice was ignored at first and the fire was lit with newspaper, small dry sticks etc. and it refused to catch or stay alight for more than a few minutes.

Subsequent lightings were no problem probably because the latent heat from the brick chimney stack kept the flue warm enough. Never had any problems with the draw on the chimney. That is unless the baffle needs cleaning which is weekly routine maintenance in season. Mine is a Charnwood with a back boiler.

Mine has one of the TEC powered fans on top which moves the trapped warm air out of the fireplace enclosure into the main room. They make quite a difference.
