It's easy to see why Vanguard has earned its reputation as the name to trust in zone heating. Our heating and hearth products let you have it all: unmatched comfort, stylish beauty and dramatic energy savings. Vent-free gas heating saves you money too, thanks to a simple concept called "zone-heating." By providing extra heat to a zone-family room, dining room, den or other area-you can set your main thermostat lower, that way you're not heating the entire house therefore producing remarkable energy savings!
