What Makes a High Efficient Furnace So Efficient?
What Makes a High Efficient Furnace So Efficient? by Mike Meincke
With today's rising energy demands, volatile financial & housing markets and a constant potential of increased living costs looming over our shoulders, catching a financial break anywhere we can as a consumer should be of keen interest to everybody. 90%+ Annual Fuel Utilization Efficiency (AFUE) furnaces may easily provide the solution and can easily off set a household bill or two with all of the energy being saved by this furnace in contrast to the conventional 60-80% AFUE furnace that is more than likely currently in your home even as you read this article. 90%+ AFUE furnaces have a 2 heat exchanger design to avoid wasting heat, in the past the product was problematic when it was first developed in the 90's, but has since been improved to near perfection today by most manufacturers to be a very reliable product and if sized properly and installed properly will save an incredible amount of money on the utility bill that you can capitalize on year in and year out.
The two heat exchanger design is the key feature that allows a 90%+ AFUE furnace to operate so efficiently. A primary heat exchanger handles the ignition of the furnace and the natural gas fire (propane, kerosene, heating oil or what ever the furnace burns) of the furnace burners. As the burners are engaged inside of the heat exchanger, the heat exchanger gets hot so that when the furnace blower turns on, forced air travels over the hot heat exchanger to allow for heat transfer to occur, sending warm air through your air ducts and to ultimately heat the air in your home. With a conventional 60-80% AFUE furnace that is all that is present for a heat exchanger, but through brilliant engineering furnace manufacturers realized that flue gases always creates hot moisture that is typically wasted out of the flue pipe and so they decided to capture this free energy by designing a better product. So engineers went to work to produce the two heat exchanger furnace and incorporated a secondary heat exchanger that looks like a coil to capture the hot flue gas moisture to re use this heat in a more efficient appliance, rather than wasting this heat out of the flue pipe.
Remarkably after 70 years of relatively little change in the heating market in terms of how a furnace basically operated, a vastly more efficient appliance emerged on the market. Two stage technology emerged as well, where engineers realized that a furnace did not necessarily have to high fire gas at all times to effectively heat your home, due to varying weather outside of your home. The two stage gas valve emerged to where a low fire predominately occurs on temperate (less cold) winter days saving an additional 25-35% on gas consumption and then when the weather gets real cold outside the furnace can engage a high fire to ensure that the appliance can keep up with heating your home only when high fire is truly needed, to ensure that the homeowner gets the best of both worlds; saving money and staying comfortable.
A conventional furnace is missing these features, because the conventional furnace can only fire in one stage and just wastes flue gas moisture out of the flue pipe. The venting of a 90%+ AFUE furnace is typically done with PVC piping material and most often is vented to the exterior side of a home. The 90%+ AFUE furnace burns and exhausts vastly more cleaner gases than a conventional furnace effectively lowering emissions as well, so you can feel good about doing your part in the environment when you have a 90%+ AFUE furnace installed in your home.
Some contractors are afraid to install a 90%+ AFUE furnace in your home due to lack of training and an inability to successfully repair furnaces in the first place. One legitimate complaint and or criticism that was true in the past, that these contractors would make, is that parts were more expensive on a 90%+ AFUE furnace and why on earth would you want an expensive repair bill they would ask. That all came to an end when Rheem manufacturing designed their new line of 95% AFUE 2 stage furnaces. All parts selected to make the Rheem 95% AFUE 2 stage furnace work are of quality durable design, but cost effective to repair after the furnace warranty expires.
This would not be the case with the expensive Carrier induced draft motors and chip boards or the expensive chip boards used by Trane and American Standard or all parts by Lennox being of higher expense in their product lines of 90%+ AFUE furnaces. Furthermore, Rheem realized that the primary heat exchanger was the most expensive part of the furnace, so they decided to make a primary heat exchanger tougher than any other manufacturers primary heat exchanger.
The Rheem primary heat exchanger is constructed of stainless steel and is of a tubular design with virtually no seam points present on the part, kind of like a car tail pipe, which rarely breaks. Eliminating seam points on the heat exchanger increases the life span of the part. On the contrary, the Lennox, Carrier, Trane and American Standard heat exchangers are a cheaper clam shell design that is no where near as strong as the tubular designed heat exchanger. The clam shell designed heat exchanger is designed to last a certain amount of years, but once enough time goes by these heat exchangers typically fail due to 4 sides of crimped seams separating the heat exchanger, leading to part failure.
Not only is the Rheem 90%+ AFUE line of furnaces tougher and built with cost effective parts in mind, but they even went as far as ensuring that all Rheem furnaces operate at a vastly lower decibal range making the Rheem furnace the quietest class of furnaces in the residential market today. Carrier, Trane, American Standard and Lennox furnaces will work and if sized and installed properly will last for many years, however when they break, you will surly pay a pretty penny to get them fixed.
When you call out an HVAC company or contractor to perform an in home estimate to install your 90%+ AFUE furnace, make sure that they are evaluating your whole house. Proper furnace sizing will involve an estimator to evaluate wall insulation type, attic insulation type, home exposure, window type, slab type, outdoor landscape, fire places present, duct sizing, how many people occupies the space as well as a few other factors too.
Be leery of the estimator that is in and out of your home in 30 minutes or less, because getting it right during the estimate phase will have a huge effect on achieving maximum efficiency of the furnace and your over all indoor comfort for many years to come. Most of the estimates that reputable heating and air conditioning companies perform may require between 1-2 hours to gather all necessary data, answer customer questions and to write an up front price to do the work.
There are many like minded good companies and contractors out there that conduct themselves that way as well. Your best bet would be to just call out an ACCA member company to perform the estimate, because an ACCA member company will operate professionally, follow higher HVAC standards and receives accredited support in training, up to date trade information and will be up to date with new techniques and standards in the HVAC field. and use the contractor zip code locator to find an ACCA member company near you.

Pop, Popper Your Popcorn Maker
Pop, Popper Your Popcorn Maker by David H. Urmann
Popcorn maker that is also called popcorn machine is a device used to pop popcorn. It was usually found in movie theaters, amusement parks and carnivals.
During early years there were no popcorn makers, Indians made popcorn by heating sand in a pan and then they put the kernels on the heated sand. Many years later, Charles Creators was the first person to invent the mobile popcorn machine, which is also known as the popcorn maker cart in 1893 in Chicago, Illinois. This machine made it easy for the people to sell the popcorn on the streets and on the amusements parks, which spurred the popularity of popcorn.
The first popcorn maker was steam driven which The Food Service Equipment Division patented in 1885. It allowed the popcorn to be popped in oil, and then later, they had a gas powered popcorn vendors. People began selling popcorn using this machine on the streets, in front of the amusement parks, stores and theaters to attract people to buy popcorn. Percy Spencer from the Raytheon Manufacturing found a way to mass-produce magnetrons to produce microwaves and with this technology, it gave Spencer the idea to make a microwave oven and he used kernels for his experiments. In 1940's, it allowed the people to make popcorn in their own homes using the microwave; you can enjoy eating popcorn even if you are not on the amusement parks or in cinemas. The Food Processing System divisions grant the exclusive right to market the hot air fluidized bed oven to produce high amounts of popcorn that in 1967.
Today, people are buying old-fashioned popcorn makers to cook delicious popcorn in social events or for one's own pleasure at the comfort of one's home. People want to purchase popcorn maker because they may need to make more than cooking a few bags of microwave popcorn. Owning a popcorn machine would be fun for a family and friends to spend some quality time together while watching your favorite programs on TV or movies. Popcorn makers have different types and brands but today, most popcorn makers were run by gas or electricity. Most people usually buy red popcorn machine because it gives out an old fashioned and traditional look to the first ones that were made in the late 1890's and 1900's. Popcorn makers have different range of prices depending on the amount of popcorn the machine can produce and if they have cart. There are two types of popcorn makers available for home use, hot air poppers that allow you to make fat and salt free popcorn that is the healthiest way of making popcorn and oil poppers that uses heated oil to cook the popcorn.
You can also check it out your hand at the stovetop popper; this is the long-standing method of popping corn that is still used today and also the most complicated to use because most of the time it might overcook the popcorn you are cooking. There are other models that use electricity and sit on the counter top, which allow you to control the amount of toppings that go into a batch of popcorn, just as you can with an air popper. The popcorn and popcorn makers have become popular that there is a museum of popcorn. This museum is called Wyandot Popcorn Museum, which has many refurbished antique popcorn machines that was invented in the late 1890's and 1900's. The Wyandot Popcorn Museum is situated in Marion, Ohio, which unwrapped to the public in September of 1982. W. Hoover Brown and the only popcorn museum in the world founded the museum.
