I live in upstate NY. I am looking to buy a pelllet stove for my Tile Showroom., which is approx. 1400 sf with high ceilings and NO insulation between the walls! Cost me $900. a month last winter to heat the place and it was still FREEZING What would be a very Low maintence, easy to use pellet stove suggestion? I will be operating it myself (female) and want easy to use operation. No ornate trims just a stove to supplement the heat problem. Suggestions, please. I can get Quadra, Lopi & Avalon Stoves where I am.
