Review on UK-15 Infrared Patio Heater - Wall, Ceiling, or Optional Stand Mount, Remote Control, Electric, 1500-Watt, Bronze Color, Energy Efficient by Tricia Rosinski

I use it to heat a 10' x 13' greenhouse that is 12' tall at its tallest point. Although these are my first few days of using the UFO, it works well. It keeps the ambient temperature around 72 when the outside temperature is 44. It has the performance I need at a decent price. It's quiet and the light from the heater is minimal. I hope the hype is true and my energy consumption will be much lower than a traditional forced air heat pump. Cons: It doesn't have a programmable thermostat and the manual isn't very helpful.
