Because the system produces steam independently of furnace plenum heat, it is the premier choice for homes heated by variable-capacity heat pumps, radiant in-floor hydronic systems, large luxury floor plans up to 6,200 sq. ft., or structures with humidity-sensitive hardwood flooring and fine architectural millwork. Packaged with the Model 62 Automatic Digital Humidifier Control and exterior temperature sensor, the unit modulates moisture delivery 24\/7 to prevent window condensation throughout harsh Canadian winters.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrode steam technology\u003c\/strong\u003e — electric current passes through natural minerals in water to boil steam efficiently without exposed heating elements that foul or burn out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-voltage electrical flexibility\u003c\/strong\u003e — field-configurable for 120 VAC, 208 VAC, or 240 VAC supply power to deliver 11.5, 16.0, 20.5, 23.3, or 34.6 gallons per day.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndependent moisture delivery\u003c\/strong\u003e — introduces steam directly into the supply plenum regardless of furnace firing rate, ideal for heat pump and geothermal systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic digital humidity control\u003c\/strong\u003e — includes Model 62 digital controller and outdoor temperature sensor to dynamically modulate indoor humidity based on exterior winter temperatures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap water compatibility\u003c\/strong\u003e — operates on municipal or domestic well water between 3 and 36 grains per gallon; no reverse osmosis or water softening pre-filtration required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple annual maintenance\u003c\/strong\u003e — disposable Model 80 steam canister unplugs and replaces in minutes without mechanical scrubbing or acid descaling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSizing guide\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003e240V \/ 16.0A (34.6 GPD \/ 131.0 L\/day)\u003c\/th\u003e\n\u003ctd\u003eTight construction up to 6,200 sq. ft.
