Green tea, as well as Oolong tea & Black tea, are produced from the herb Camellia Sinensis. They all contain the same amount of caffeine. Caffeine content in a cup of tea is 2.5% to 4%, which is about a third of that in coffee. It is claimed that 80% of the caffeine in tea remains unabsorbed by the human body.
Wood Stove Flue. It is critical to control the air moving in and out of your wood stove. Improper ventilation can cause health issues and be a fire hazard.The wood stove flue helps control this. A flue pipe is a vital part of the exhaust system of the wood stove installation. The flue gases which are released as a result of combustion of wood fuel are hotter than the normal temperature and automatically go upward so it is preferred to install the wood stove flue and chimney in the upward direction.
Note: Some stoves (Ekol 5 and 8 for example) CANNOT be swept through the stove so you will need to have a sweep-door in the pipe between the stove and the closure plate (in an elbow or in a straight section of steel vitreous pipe). Also see: Air gap above stove. This black steel vitreous flue does not have an offset. The pipe is passing through a sealing plate (available from our store). Note the A1-fire-rated Hardiebacker lining board within the recess.
