WHY USE STEAM?


Steam humidifiers are by far the best humidifier system, they are superior in maintaining relative humidity in homes. The output is not limited to or tied to the furnace heating cycle and homeowners can maintain RH in the space regardless of where the thermostat has been set day or night. If the consumer is concerned about their IAQ in the home and wants to preserve their valuables steam is the answer.

GeneralAire’s Elite Steam Humidifiers are electrode steam humidifiers and do not use an electric element; rather they use electrode plates to pass current thru the water.

The electrode type unit uses the mineral laden water as a conductor to pass electrical current from one electrode to another. The transfer of the current through the water generates resistance, creates an amp draw, and produces heat.

The heat generated will increase the temperature of the water to a boil creating steam. Electrode systems are also referred to as replacement canister steam humidifiers because the electrodes are housed in a plastic canister and when the system can not longer reach a targeted amp draw the canister will need to be replaced. The replacement time of the canister will vary due to water conditions and output demand on the humidifier.

Electrode technology has been available for over 30 years and is commonly used in commercial applications. Electrode humidifiers have advanced controllers because they are not just energizing an element to heat the water they are monitoring the activity in the canister based on electrical amp draw. Since all water varies with mineral content and water conductivity every unit will have to adjust to the conditions it is being operated in.

The adjustments come from how much water to put in the canister to reach targeted amp draw (humidity output) by exposing more or less electrode, as well as draining and filling based on activity in the canister. Our systems have programmed logic to activate an alarm when the canister is exhausted and can no longer meet the target amp draw. This will require the canister to be replaced by a qualified HVAC technician.

Electrode humidifiers are steam generating units that mount near the HVAC system and distribute the steam to the duct work using steam hose and distribution nozzle. Electrode steam humidifiers allow manufacturers to build larger capacities while still maintaining a small footprint.

INDOOR AIR QUALITY

When cold, dry air enters your home and is warmed to room temperature, the relative humidity in the average house can drop to as little as 5%. Compare that to the average 25% relative humidity of the Sahara Desert and you can understand why the air inside your home can seriously affect your health and comfort. Since various studies have estimated that most people spend as much as 90% of their time at home indoors, there’s reason to be concerned about indoor air quality.

How does humidity AFFECT my 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 discomforts. That’s why many doctors recommend humidifiers for allergy and asthma sufferers.

Research has shown that 30% – 60% relative humidity is ideal. Outside this range, bacteria, fungi, viruses and mites thrive and multiply. As these creatures increase in number, so does your risk of being adversely affected.

Are there any other BENEFITS to properly conditioned air?

Yes, it can help you save energy! 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%.

Humidity Control For Your Comfort, Health and Protection



Research has shown that 35% to 60% relative humidity is ideal for today’s homes.

Outside this range, bacteria, fungi, viruses and mites thrive. Proper relative humidity provides a comfortable environment for your woodwork, your furniture, your plants, your pets and especially you and your family.


Humidity Load and Your Home!

Humidification is necessary to protect and stabilize wood floors, trim, cabinets, and other furnishings in your home. A humidity load for your home is crucial to meet proper expectations of performance for your new humidifier. Gallons Per Day (GPD) is based on performance output at 120 degree air temperature, 24 hours continuous per day. One must estimate the run cycle time of their furnace. Then determine actual output any humidifier may deliver to meet your home’s humidity load requirements.

Air quality is only a concern outdoors, isn’t it?
Not true! The air inside your home can be even more of a concern to your health and comfort, especially in the winter.

Breathing dry air is a potential health hazard which can cause such respiratory ailments as asthma, bronchitis, sinusitis, and nosebleeds, or general dehydration since body fluids are depleted during respiration.
