This is Old news : Open fires are worse than stoves. They haven’t even mentioned that.
Stoves are better than open fires. The Clean Air Act research had proved that, and the new modern stoves are even better still. They are only just behind oil fired boilers in terms of efficiency and cleanliness.
Pm2.5 is produced at higher levels when the stove is started, slumbering (low temperature for a long time) or going out.
Running it within its optional temperature range dramatically reduced the amount of pm2.5 it produces over all as it combusts the fuel efficiently.
Over all, the whole point of the Clean Air Act and all these little studies is that we will have to move away from burning at home completely. Probably in our lifetime too.
News on all the sweeping forums is that studies have found that the new clean air act hasn’t had the affect on air quality that the government wanted to see. This is primarily due to people still burning “wet” wood collected themselves or wood above the recommended %.
Combine that with the amount of dodgy installations, the amount of broken, not serviced and old stoves and finally, those who don’t sweep their chimneys regularly, this is why it amount of pm2.5 hasn’t dropped as predicted.
The next move, within the next 2-3 years will be to get sweeps to report all none compliant stoves they see to councils who will serve cease and desist notices on the owners forcing them to either buy a new efficient stove or probably because of the price, stop burning at all.
