Furnaces have become more energy-efficient over the years. A gas furnace made in the early 1970s typically has an AFUE of about 65 percent. The lowest efficiency allowed by law for new gas furnaces is 78 percent, and some new models achieve 97 percent--near-total efficiency.The price of a furnace generally rises in step with its fuel efficiency. A furnace with a 90 percent AFUE might cost $1,000 more than a similar size unit with an 80 percent AFUE.eplacing the old furnace in your central heating system with a new, more efficient model can offset volatile energy prices. Money aside, today's furnaces pollute less and boost comfort by producing heat more steadily than older furnaces. Gas is the most common heating fuel and this report focuses on gas furnaces.

Basophilic stippling is a term that refers to a specific appearance of a red blood cell under the microscope.It is an abnormal collection of nucleic acid in dots throughout the cell and indicates the presence of disease. The stippling is only obvious in the cell after it has been stained with a particular sort of dye.tippling is a word that means something looks like it is covered in dots. Basophilic means that the cells that show the stippling are stained with a basic dye. A basic dye is alkaline and interacts with the negatively charged molecules inside a cell to produce a coloration.
