Steam Humidifiers

Thermolec Acu-Steam Humidifiers

Thermolec Acu-Steam humidifiers are the most dependable and easiest to maintain steam humidifiers on the market. Acu-Steam will tolerate a variety of water conditions. Its unique design includes self-cleaning elements enclosed in a quick-release stainless steel tank, eliminating the need to buy costly replacement tanks. Element and tank carry a 10 year warranty. A pressure switch is included as a standard feature, assuring that steam is not introduced into the ductwork if the system fan has failed. Three sizes cover from 13 to 37 gallons per day.

Thermolec Split-Steam Humidifiers

Split-Steam Humidifiers are specifically designed for applications without ductwork. An Acu-steam unit is paired with a wall mounted, fan powered steam distribution module providing an effective way to maintain humidity in ductless applications. The distribution module’s low profile faceplate is all that’s exposed on the finished wall. This 13 gallon per day unit can be located anywhere that there’s electricity, water and a drain.

Why Install a Steam Humidifier?

Proper humidification is one of the most critical indoor air quality considerations in any home. Ideal humidification (generally accepted to be between 35-40%) means a healthier indoor environment for people. It keeps furnishings such as wood flooring, furniture, musical instruments, paintings and collectibles from self-destruction. Steam humidifiers lower heating bills(the set temperature can be 2 degrees cooler to attain the same level of comfort). The steam humidifiers also cut down on dust and eliminate static electricity. Standard flow-through humidifiers have major shortcomings such as significant water waste (up to 50 gals a day!), require a heat call from the furnace in order to activate and are viewed by many in the industry as ineffective performers. Flow-through humidifiers have pads that water and air flow through and are contaminant traps for mold, bacteria and viruses which eventually get dispersed into a home via the HVAC system. Conversely, steam humidifiers humidify with sterile steam, are available in larger capacities, effectively humidify more quickly and do not require a call for heat to activate. They have minimal water waste and effectively humidify with lower temperature output heat pumps. Bottom line, it’s like comparing apples and oranges on the basis of which makes the best apple juice!
