Optimus Infrared Quartz Heater with Remote Control & LCD Display - Brown - Perfect for Bedroom, Office, and Living Room Heating

It's not winter yet but has been as cold as 32 overnight. I can't comment on the cost yet and will update when the energy bill arrives.I'm using this to supplement the heat on my second story colonial home. UNDERSTAND INFRARED TAKES TIME TO PENETRATE YOUR WALLS, FLOORS , FURNITURE AND YOU! IT DOES NOT HEAT THE AIR. This little unit is a very nice looking cherry stained cabinet that matches the furniture. It has a luminescent blue LED SCREEN like a high-end appliance. The heat is FAR FROM INSTANT. It takes hours to heat up BUT once it does after maybe 4-5 hours for my second story 2300 sq ft home it is a wonderful pleasant heat. Even the cold bathroom tile floor is pleasantly warm!I have yet to turn my furnace on but if this is energy-efficient when the bill comes, I will order a second for the downstairs . Infrared is a penetrating heat that will take the chill off. So far this is a thumbs-up unit! In addition I got it directly from amazon and it shipped overnight!
