What are the Benifits to Installing a Furnace Humidifier

One of the most common health issues that plague our society is dehydration. Most of the tissue in the body is composed of water. If it loses the water, the tissue dries up. It's elasticity goes, and with it function declines. Besides dry skin, the symptoms of dehydration include chronic joint and muscle pain, raspy throat, sore eyes and lack of mental concentration.

There are two ways to combat dehydration, and both are essential; drink a lot of water, and maintain the relative humidity in the home and office at comfortable levels with the use of a furnace humidifier.

How does humidity AFFECT our health?

Conditioning the amount of moisture in the air with a furnace humidifier is necessary for your family's health. Dry air in your home can make your throat feel dry, and cause or aggravate respiratory ailments.

Inadequate humidification during cold weather is one of the major causes of respiratory infections. The heating seasons causes people to begin having repeated attacks of winter colds. Winter is blamed for these problems, but the actual cause is dryness, which develops in the membranes of the nose, throat and bronchial tubes. Relative humidity also has a significant effect on controlling the occurrence of airborne infections.

The one thing we can do about alleviating some of the discomfort of colds, dry noses and dehydrated skin is to install a humdifier in the home, where we spend most of our time. Actually, for many, dry air is an air-quality issue. Dry air promotes the growth of some bacteria, viruses and respiratory irritants that in sensitive individuals cause conditions worse than dry skin. Adequate moisture enables the body's immune system to defend better against indoor respiratory pollutants and irritants.

How will a furnace humidifier affect your comfort?

Humidity in the home will affect your comfort. Since the air in your home is always trying to reach its saturation point, it will absorb water wherever it's found, that means it is stealing moisture from the bodies of you and your children, your pets, your furniture and even your house plants. By giving up moisture to the air, your skin, throat and nasal passages dry out and crack leading to various physical discomfort. That's why many doctors recommend furnace humidifiers for allergy and asthma sufferers.

How does humidity AFFECT my house?

Virtually everything in your home made from wood contains some moisture. As dry air sucks that moisture out, the wood shrinks and cracks. Hardwood floors separate at the seams, furniture shrinks and cracks, and doors warp and no longer fit their frames as the moisture is drawn off.

Also, perhaps the most annoying effect of dry indoor air is static shock. How many times have you shuffled across the carpet, only to be rudely surprised by the crackle of static as you reach for the light switch! It's no fun when it happens to you, and even less so when you reach out and "zap" a loved one. With the capacity to hold a static charge up to 20,000 volts, your body can also wreak havoc on home computers and other sensitive electronic devices. By maintaining indoor relative humidity at 35 percent or higher with the use of a humidifier, static shocks are greatly reduced.

Are there any other BENEFITS to installimg a furnace humidifier in the home?

Yes! Proper relative humidity helps you save energy costs. Warm, humid summer air feels hotter than it actually is because of the moisture it contains. That same principle applies to your home in the winter. By keeping the relative humidity inside your home at an ideal level, you can turn your thermostat down a few degrees and still feel comfortable. Dialing down your thermostat just three degrees can reduce your heating bill by as much as 5%.

Furnace Buying Tips

Choosing a furnace for your home is not difficult. The following list are features that you may want to look for when buying your furnace.

1. What type of furnace do you want? Will it be Gas or Electric?

The Gas Furnace

The gas furnace is always more affordable to use than the electric furnace where gas is readily available. On the downside, burning fuel generates fumes. In well-maintained gas furnaces, the fumes generated are enclosed in the exchanger and then exit the house through an exhaust vent.

Remember, a gas furnace must be checked by a qualified professional at least once a year. The professional would check the furnace for holes, leaks or cracks. A break or crack in the furnace lets carbon monoxide seep into your house or place of business.

The Electric Furnace

The electric furnace has a higher cost than a gas furnace. On the upside, since electric furnaces do not use flames, it does not generate any carbon monoxide. The electric furnace is cleaner and safer than a gas furnace.

2. The Quality of the Furnace

The quality of the furnace determines how long and how well it will perform. Choosing a brand of furnace that has a history of quality and reliability can be less costly in the long run. Ask your contractor about which brand will be optimal for your needs. A free estimate for the purchase and installation are available in some companies.

3. The Efficiency of the Furnace

The efficiency of gas furnaces are determined by the AFUE or Annual Fuel Utilization Efficiency ratings. The AFUE ratings identifies how efficiently is the fuel being consumed. In most cases, a higher AFUE rating means it takes less fuel to heat your home.

Gas furnaces with higher ratings cost more than those with lower ratings but may save you more money down the road. A minimum rating of 78% is established by the government in 1992. Many furnaces have an efficiency rating of about 60% prior to 1992.

a. The Mid-Efficiency Furnaces

The mid-efficiency furnaces are also called ?induces draft furnaces? or ?non-condensing furnaces?. The mid-efficiency furnace offers the bare minimum of 78% efficiency up to about 80%.

b. The High-Efficiency Furnaces

The high-efficiency furnaces are also known as ?condensing furnaces? or ?sealed combustion furnaces?. The high-efficiency furnaces has an AFUE rating as high as 96%. Some furnaces use a two-stage valve and an efficient variable-speed motor to raise comfort and effectiveness.

4. The Comfort features of furnaces

Several furnaces provide features that increases comfort and efficiency.

a. The features of the two-speed furnace

The furnace can function at low speed for most of the time. It allows for a more quieter operation for a longer amount of time compared to a ?single-speed furnace?. The longer run periods allow for fewer start/stop cycles, less drafts, and very little temperature variance.

The temperature swing is limited to about two degrees compared to the four degree variance of the single-speed units. The two-speed unit gives better circulation which prevents warmer air from rising and the cooler air from settling down. The two-speed unit gives a more consistent temperature in the house.

b. The features of variable-capacity furnaces

Furnaces with variable capacity provide a combination of efficiency and comfort. The variable-capacity has a motor that regulates your needs by automatically adjusting air volume and speed. The var-cap furnace provides the most efficient heating and cooling.

A fan comes with the var-cap furnace. The fan will reduce your cost during summer. If the fan is used throughout summer, the central air conditioning unit increases in efficiency.

5. The furnace noise level

Unfortunately, all furnaces do not come with a standard rating system for sound unlike heat pumps and air conditioners. Although, two-speed units and var-cap units generally operate at a low noise levels.

The two-speed and var-cap furnaces run for longer periods and lower sounds than the standard unit. Certain var-cap units has features that prevent ?creaking? of the ducts due to expansion and contraction caused by changing temperature. The temperature differential is reduced so that the creaking noise is also almost eliminated.For more great furnace information and resources check out: http://www.furnaceadvisor.info

TLC For Your Furnace - Avoiding Premature Failure of Heat Exchangers

Ever notice how your car seems to run better right after an oil change, especially if you wash and wax it? Well, it's the same for your furnace... don't laugh, I'm serious!

The main component of heating units, both forced air and hot water, is the heat exchanger. This component takes the heat produced by burning fuel and transfers it to the water or air for distribution throughout the house. In a hot water system this component is usually concealed from view, and in a forced air unit only 10 to 25% (sometimes it's completely hidden) of this component is typically visible without disassembly.

Cut-away view of a modern forced-air gas furnaceModern forced-air gas furnace:

1. Solid-state furnace control (Fan assembly visible at lower rear)

2. Draft inducer (fan-forced exhaust)

3. Igniter and flame sensor

4. Gas valve and manifold

5. Gas burners

6. Heat exchanger(s)

7. Air filters

(Configuration will vary between models)

What usually makes heat exchangers inoperative is developing a hole or a crack that allows the hot water to escape, or exhaust from the combustion fuel to escape into the interior air of the home. Constant heating and cooling from years of use will eventually cause a heat exchanger to crack, however some last longer than others. Under ideal conditions, many survive well beyond their predicted life spans.

It seems regular cleaning and maintenance play a factor in life expectancy, as does the environment surrounding the unit. Damp environments tend to assist the build-up of rust on the heat exchanger, shortening its life, while dry, clean environments tend to increase the life span of most furnaces.

Reduced airflow...

Dirty air filters and fan blades, dirty ductwork and obstructed air vents can all contribute to wear on fan motors, reduced efficiency and even premature failure of heat exchangers. Fuel-fired forced-air furnaces are prone to overheating due to obstructions to airflow. Modern furnaces are designed to shut down if temperatures become dangerously high... however, moderately elevated internal temperatures caused by dirt, dust and debris may not be high enough to switch off a furnace, while remaining high enough to cause metal fatigue over extended periods of time.

An annual internal inspection by a licensed burner mechanic or gas fitter, including cleaning and testing for exhaust leaks, should cost between $50 and $100. Considering the implications, I'd say that's a real bargain! Why not have your furnace inspected, and treat yourself to some peace of mind? For those of you with gas furnaces or wood stoves, a carbon monoxide (CO) detector ($30-$45) is an inexpensive means of protection against the possibility of exhaust leaks, between inspections.
