@@TheTortoise Thanks Gabe, makes me wonder about our stove, it has a 7 metre liner, we are on the side of a hill, and it smokes back into the room at every opportunity, seriously consider a bottom draught system from outside which should help.
I've just done a talk on the PM2.5 issue. My conclusions included that modern ecodesign stoves, being used properly, emit very little particulate pollution. Also to be taken into consideration is that the atmosphere contains both primary particulates and secondary particulates. The secondary ones are formed from gases typically given off by cars, some time after the car (or industrial process) has emitted the gases. Woodstoves are definitely not the cause of the majority of the PM2.5 pollution. Also, over the past decade, the levels of PM2.5 have gone down significantly, and they are currently low!
It would be really interesting to see the baseline PM2.5 in your room and then how this varies when the stove is first lit, to when it is burning at its optimal temperature, then following reloading, and finally levels when shut down low for an overnighter. I suspect it will remain in the safe zone, but curious to see the fluctuations above.
I did do a bit of this type of testing in our PM2.5 video, so that may be worth looking at. ruclips.net/video/hsi07iYETnc/видео.htmlsi=oui1LX4FEPVqGtGK
@ will do! Your video on particulates was very good, the context of other contributors in the home put the effect into perspective. I would imagine the levels driving around or in town would be consistently high. I’ll get my stove thermometer from you - there’s a fair lead time on the Dik Guerts log store model so bit of a wait yet!
I used a 5kw Eco stove and a slightly larger 6kw non Eco stove. Chimney is only about 4-5m tall. The efficiencies of the stoves is: Morsø Ø6 75% Clock Blithfield compact 84.3%
Been curious about the emissions for a while now, I’d heard the thing about so many hgvs of emissions but I take hgvs to mot test and it’s rare they ever give any particulate reading at all , even 20 year old trucks blow zero 🤷♂️
@ yep, it winds the vosa mot testers up as pre covid they never bothered and now they have to go through a 5 minute routine to return a 0.00 result every time 🤷♂️ Cars interestingly do return a result on every test I’ve done although a euro 6 is often very near zero
I bought one of your stoves the Woodford Lowry 5x and honestly very disappointed in the crap vermiculite board and 2 months in and the sides are crumbling and the top brick is split in two I understand it’s a consumable part but say If you fit new tyres and they last 2 months or break pads etc it’s not right and the cost of them is ridiculous £189 and you won’t do anything about it
My Morsø Badger is still on its original firebricks after 11 years. The only thing I've had to do to it, except an annual sweep, was new door rope at 9 years. Morsø stoves are not cheap nowadays, though.
Bricks is always a tricky subject. Generally the time they last is directly controlled by the user, so every manufacturer operates in the same way, and 95% use the same material (vermiculite board). In the same way that doing wheel spins will destroy tyres, bumping bricks with logs will cause the issues you’ve described. We sell the bricks, but we’re simply drop shipping them from Woodford themselves, so we have no control over their warranty procedures, though what you’ve described is standard to all manufacturers I’ve encountered. Shame, that it’s not worked perfectly in this case, but hopefully the description of the cause will prevent a repeat of the same issue.
If the bricks are crumbling after only a couple of months it might suggest to much glue in the bricks, years ago I worked for a manufacturer of stoves and this happened that manufacturer replaced the bricks free of charge. Obviously can’t speak for your manufacturer.
I find the alarmist approach laughable when you look at city centre pollution from coal in the early 1900s…. A wood stove in winter is not going to expose anyone to very much given people do not go outdoors near homes very much in the heating season.
It's a problem in big cities, where stoves aren't really a good idea anyway. Out in the sticks, they're more useful as wood is more easily found and your oil tank might run empty.
@ we are told it’s a problem but as this video demonstrates the measurements are very low. Additionally the standard of the stove and the flue are important to ensure complete combustion AND a flue that discharges hot flue gases that then rise in cold air and disperse. Well seasoned wood makes combustion relatively clean. The idea of a sterile environment is contrary to natures balance and some wood smoke I find a very pleasant odour especially pine.
Interesting. Looking forward to seeing the results with the cowl. 👍
Yea it’s a fantastic product!
Have you tested in the room, when you open the door?
We did some testing in this video, but it honestly changes every day:

yea always worth trying to fix things before adding powered flues, that way you can trust things even in a powercut.

Interesting stuff. Thanks for the comment, I didn’t know about primary and secondary particulates.

@@TheTortoise I’ll check that out thank you, great channel you have. About to order a Dik Guerts Ivar 5 with external twin wall system.
That’s an exciting purchase. Let us know how you get on, it’s a great stove!

Be interesting to check particularly in towns.
It’s almost more exciting, waiting for a bit. It’s a great stove.
Lived in hong kong. Average was 80-120 daily pm2.5. We have nothing to worry about here 😂
Flippin heck!!
Too right, we’ve got a bit of a storm in a tea cup here! 😅
How tall/high is your chimney? What is the kw rating and efficiency numbers? Interested to know what you are trying to test.
I used a 5kw Eco stove and a slightly larger 6kw non Eco stove. Chimney is only about 4-5m tall. The efficiencies of the stoves is:
Morsø Ø6 75%
Clock Blithfield compact 84.3%

Really???
All exhausts that I’ve tested have plenty of particulates coming out 🤷♂️
@ yep, it winds the vosa mot testers up as pre covid they never bothered and now they have to go through a 5 minute routine to return a 0.00 result every time 🤷♂️

That’s amazing!😅
Ooh, a New Toy. . . . Gimme Gimme
Is that a BTMETER. . . BT5800D. . . ?
One of those would be Handy
Only trouble is you can look a bit of a lunatic, running round testing things, particularly with a camera 😅

Hello from Flushing, better stoves here in holland😂. Joke
😅 well I’m a fan of the Dik Geurts stoves!
