charnwood multi-fuel stove

martythepiper

Hi Folks,

I have just had a Charnwood 16b multi-fuel stove installed. It is in a newly built house with new chimney liner and linked to the oil-fired heating system. I have spent all day with it burning a mixture of logs that have been seasoned for 2+ years and factory compressed peat. The oil heating has been off. It houses a roaring fire behind the glass which leaves the chimney breast almost white hot (and has put a lovely crack the whole way down my freshly rendered chimney breast) but throws little or no heat into the room. The unit, while hot, is just not what I had expected and the heat in the chimney breast is worrying.

Any help would be much appreciated.

Thanks in advance.

open the doors on it.

Parents have a Charnwood CW40B - if you want the edge taking off, leave it closed, adjust the flap valve and secondary intakes to suit. For more heat in the "stove room", open the doors on it.

Is yours linked into the CH?

I've had the 40B overheat before when it's been forgotten and the top left shut wiith the ashpan open..like an uncontrolled blast furnace. Vibrating chimney stack, boiling in the CH piping etc..if you find it's roaring and over-producing heat, check the seals on the doors, the air valve adjustments etc.

Most of the time, mums sits with a nice banked red glow and does a nice job of keeping the room with it in warm, along with the upstairs radiators. It'd do the downstairs ones quite well, if I could be hassled to change the pump 'stat so that it cut in at some point below meltdown..

Contact the installer/supplier.

Once you've had the installation checked and have got the hang of controlling the 'roaring fire' to a more gentle burn then you could consider one of these .....

Should spread the heat about a bit without using any electricity!

Is it in the inglenook or proud of the wall?

Thanks everyone for the help. I have got to the bottom of the problem and it may be of interest to other woodburners. There is too much "draw" in my chimney which is pulling the heat up. The flue pipe at the top of the stove needs to be fitted with a damper. This is a circular piece of cast metal which fits into the interior of the flue pipe with a mechanism for adjusting on the exterior of the flue pipe. It is manually adjusted until the correct draw is established. Although relatively inexpensive at £10.99 the downside is that local stockists are out and it will take up to 6 weeks to get me one. I spent 5 hours on the phone and the internet before arriving at the solution. 10 minutes after finally resolving the problem a joiner arrived at the house to adjust some of the internal doors and matter-of-fact told me exaxtly what the problem was, how to fix it and how common an issue it is in this part of Ireland!

Thanks again to everyone for their help

Make sure you dont use the damper too much it can cause a build up of condensates in the flueway if you have it turned down a lot.
