Exercise is next, which elevates your heart rate and respiration which starts the process of activating the release of stored body fat to be used as fuel for much needed additional energy. This is a critical part of the fat burning process. If however, you are only burning sugar it will be very difficult to reduce your body fat levels. Your objective is to raise your heart rate just a little higher than when it is at rest and to keep it there for a minimum of twenty minutes and building up to one hour or more at a time. Try to do this this at least five times per week by walking, bike riding or any form of aerobic exercise that you enjoy.

Lean Muscles is the furnace that keeps your metabolism running on high. Whenever someone says their metabolism is slow it is usually someone who is not doing any strength training or only does the bare minimum. Increasing this metabolic furnace is a must to keep the body fat from escalating. Almost everyone can benefit by training with some basic bodybuilding principles. Performing muscle building exercises for all of the muscle groups on your body a minimum of two times per week, three or four is better depending on your experience and fitness level. If you are not strength training you are not doing all you can to achieve your fat loss goals.

The old days:

In the old days when a service man (politically correct term today is "service tech" this term started about 21 years ago) when out on a "clean and check," he had all kinds of things to do. First he pulled out all the burners and blew them out with co2, then he checked the heat exchanger for cracks using a mirror, then vacuumed up any dirt he found. He also changed the "thermocouple" (on a standing pilot, where the pilot flame burns all the time, the thermocouple tells the gas valve there is a pilot light, and it's ok to open, and start the heat sequence) on the "pilot light" and blew out the pilot light assembly to make sure it would burn clean and that the pilot flame was positioned correctly on the thermocouple, and on the burner pilot runner.

After that he pulled the blower, and if it was a belt drive blower, oiled the squirrel cage bearings, motor bearings, and checked the belt for cracks .
On a "direct drive blower" all he had to do was just oil the bearings on the motor.

Now all the burners are cleaned and the heat exchanger has been checked for cracks and everything is back in place, including the blower.On to the next step.

Now, if the service man was worth his salt, he checks the most important part of the furnace, the "limit switch". There's a limit switch in every; gas, oil, electric, or propane furnace, or boiler.
It's main function is to turn on the blower (usually 200') and shut it off (around 110 or 100' any cooler, and you would feel like there was a draft) and the most important job it has is to tell the "gas valve" to shut down the burners incase the blower fails. It keeps the furnace or boiler (boilers also have a "safety relief valve" like hot water heaters) from over heating and starting a fire.

What the better guys did was pull the blower wire off the limit switch and start the furnace burners. With the blower wire pulled off the limit switch, the blower can't start, and when the furnaces gets to about 200 degrees, the burners should shut off and not relight again until the furnaces cools and lowers it's temperature to about 140 degrees. Some guys just checked the limit switch by rotating the dial on the limit switch and blower settings until the burners shut off. I liked taking the wire off the limit switch and testing it that way because it was more real life working conditions in the event of blower failure.

One of the last things, and just as important as checking the limit switch, was to check the "flue pipe" to make sure it, or the chimney, hasn't been blocked by soot or birds.
It wasn't uncommon to find dead birds in the flue. Some even made it into people's basements. This doesn't happen anymore with the new furnaces.
And the very last thing that was done was to check for gas leaks.

Furnaces 10 years ago to the present:

Today's furnaces and boilers don't need the kind of attention from the service man like furnaces of the past did. On most modern furnaces all that needs to be checked is the "flame sensor". The furnaces of today pretty much watch themselves. The burners almost never get dirty now a days because they are working in a mostly closed (80 plus furnaces are not, but the 90's are) environment. The blower, gas valve, and all the safety controls (including the "limit switch" and "blower switch") are run by a circuit board. The blowers are all sealed now too. They don't even need to be oiled!

So how often do we want our furnaces and boilers checked?

That's a tough question. It all depends on the environment your furnace is running in. It your furnace or boiler is running in an environment that has a lot of dust or animal hair, then it mite be worth it to have your furnace checked once a year. If your furnace is running in a relatively clean environment, you can probably get away with 2 or 3 years of not having to have to spend the money to have a clean furnace checked.

Don't forget that these new furnaces shut down when they spot the slightest problem. Some tech guys feel the only real time for home owners to have their furnaces ( don't forget where're talking new furnaces not the old clunkers) checked, is when they don't start. They don't think the cost justifies what your getting in return.

But in the end, it's the choice of the home owner to decide how often they have their heating equipment checked.

Fall is here and winter is not far behind. It's time to think about how you're going to keep warm this winter without breaking the bank.

The main thing is to have your furnace checked and tuned. Whether electric, propane, gas or a heat pump.

Do this early before the cold spells hit. If you wait until your area's first arctic blast you may have to wait several weeks, yes weeks until there is a technician able come out to your home.

Your heating equipment has been sitting dormant for several months and by having your equipment tuned up before you actually need it you can save hundreds (yes hundreds) in unnecessary repair calls.

Many people that wait until the cold hits find that their equipment fails at the most crucial time. A tune up can prevent the failure of your equipment and catch many other problems which can result in expensive repairs.

Also having your furnace tuned up and checked before you use it could prevent things like a crack developing in your heat exchanger in a gas or propane furnace which results in carbon monoxide being pumped into your home. A dangerous occurrence that happens much too frequently due to furnace neglect.

A break in your electrical elements in your electrical furnace could cause a fire.

A leak in your heat pump could lead to a break down in your compressor and reversing valve which could destroy the most important and expensive parts of your unit.

There are two main reasons for this, and they're pretty obvious. One, inefficient energy use costs more money. It's safe to say we're all looking to lower our bills and switching to energy efficient appliances is a big step in that direction. The other reason to use high efficiency appliances is the understanding that many of our energy sources are finite. In other words, eventually we'll run out.

One of the biggest users of energy in our homes and workplaces are the heating units. Just like most other major household products, gas furnaces have become more efficient than ever before. Natural gas is an economical method for home heating and now you can find all sorts of high efficiency gas furnaces on the market.

High efficiency gas furnaces tend to cost more than conventional gas furnaces. This is for a couple reasons. They're not yet produced on the same scale as conventional furnaces so there are still cost factors to overcome which have to be passed on to the consumer. Secondly, high efficiency gas furnaces employ the latest technologies, which, as we all know, always kicks up the cost of a product. Innovation isn't free. However, keep in mind, that this is just an initial start-up cost. Sure, you may be laying down more money at the outset, but the money you'll save with a high efficiency gas furnace will soon make up the difference and even pay for itself in the end.

Investing in a high efficiency natural gas furnace is well worth it, and let's not forget the environment. An energy efficient furnace will use less fuel, which means using less natural resources, and which means releasing less greenhouse gases into our fragile atmosphere. That's a cost that can't be calculated in dollars.

These days, gas furnaces have stickers on them which gives their AFUE number. AFUE stands for Annual Fuel Utilization Efficiency. A high efficiency natural gas furnace will have a AFUE number ranging from the high 80's to the high 90's. Furnaces with AFUE's below that range are considered medium efficiency. Such furnaces cost less but will also save you less in bills.

Another thing to look for when shopping for a high efficiency natural gas furnace is an Energy Star sticker. If it has an Energy Star label, that means its AFUE rating is in the 90's.

Remember, no matter how energy efficient your furnace is, you need to maintain it properly and keep it, along with your vents clean. A dirty or poorly maintained furnace will cause a drop in efficiency and increases in cost and fuel consumption.

There is plenty of helpful information available online and from your local furnace dealers. High efficiency natural gas furnaces may cost more at first, but the money you save and the benefit to the environment makes them a wise investment.
