Wood burner in thatch house
This website has never failed to provide some great advice and perspective so hope to get some on this subject.

Our farmhouse has two open fires but one of the chimneys has been condemned. HEATAS engineer says wood burner would be safer but there is a lot of conflicting information on the internet on this, much of which comes from the fact that wood burners haven’t been installed correctly or had the flue cleaned.

Just wonder what others views might be on this? Any experience would be appreciated.

Thanks

I'm no expert but to my thinking wood burners burn much more efficiently than open fires and therefore you're far less likely to get embers floating out the chimney?

I'd speak with your insurers, I'm sure they'll have an opinion. James

I’d check with your insurer, but I think the opposite is true; you’re far less likely to get embers with an open fire.

I’ve heard of some horror stores where insurers have refused to cover, increased the premium significantly following the installation of a log burner. 2011 CSW XS 90

Probably a good question for Clayton our resident thatcher! James

We work on two different thatched cottages/houses.
Both have wood burning stoves. One, it’s insurer never questions anything about the chimney. The other seems to make requests and requirements with regards the chimney. The most recent one, was a minimum requirement for the flue of the stove to be 2.1 metres above the thatch ridge. Most years on renewal it decides to bowl the owner a new challenge.
So definitely seek in writing what they require.

I understand that a common cause of fires is a failure in the structure of the chimney which allows heat through onto the thatch which then ignites. Many companies will be out there with specialist advice but i would have said that a wood burner with a liner installed in the chimney would be better than a std fire.

Built my house about 12 years ago and as well as having a fire barrier, mains linked smoke detectors, fire extinguishers and an elec inspection every year the chimney had to be 1.8m above ridge height. This was all following the 'Dorset Model' of fire prevention/protection

And insurers insist on no bonfires within 100m of the house Sad

Agree with Chugga90, they raised the height from the thatch ridge to the top of the chimney / flue from 1.8m to 2.1m so a lot of chimney flue making firms have started to make them taller so you don't have to build your chimney up higher. The other item to think about is if your roof has wire netting on one side or all over, some insurer's are ok with the netting on and some don't like it on at all, this is the same if you have a spark arrester on top of the flue, you must check this as it will be another excuse for them not to pay out.
bodstruck is right as well with NO fires within 100m of the thatched roof Thumbs Up

A wood burner would be safer than an open fire as it's the pointing between the bricks that deuterate over the years and then start leaking into the thatch, we have come across a few thatched property's that were still lucky to have the thatch on as we found evidence ( what we call " blackened thatch " ) when stripping the coats of reed off for re-thatching, if you have a chimney that has been re-pointed / rebuild from where it starts to the top then you will be good to have a open fire. 1996 Golf Blue 300Tdi 110 Pick up.

I work in two thatched properties that have stoves installed. They have had to have the chimney stack increased in height, which is a pain due to access, and also requires a fair amount of messing about with getting council, parish, and listing approval. They both require sensors in the chimney, yearly camera surveys, and swept at least once a year. They have two different tops to the chimneys as rules changed. I also know of at least four thatched houses that have burnt down due to their own fires all with slightly different outcomes all down to how insurance / rules were interpreted or complied to.

That last statement is a bit strange. I get that bonfires can cause sparks and cause a thatch fire. But what your insurance is basically saying your neighbours can't have a bonfire either. How can they insist on this? If you have a neighbour from hell, how could you enforce the no fire rule. 110 D250 SE HT

Ask them how they are going to fund the rebuilding of your house if their bonfire is found to be responsible?

In a civil court it would be 51% ~ The balance of probability standard means that a court is satisfied an event occurred if the court considers that, on the evidence, the occurrence of the event was more likely than not.
