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.
Now, hereâs the difference between standard-efficiency and high-efficiency models. In gas furnaces, there is a component called a heat exchanger. This is where natural or propane gas is converted into heat energy and byproducts produced from the combustion process are vented through the flue system. Well, in a condensing gas furnace, there is more than one heat exchanger. The secondary heat exchanger removes more heat from the combustion gases, which then condense to produce water vapor. Then, cooled flue gas is vented out of the flue system.
