Mainstay has the best oil filled radiator heaters I have purchased of any brand, I always check the heat out put with a heat gun and Mainstay brand is the only brand I've found that actually puts out the amount of heat they are supposed to on the high setting.

Kept our home warm, saved our plumbing

Our HVAC blower fan motor went out right before Thanksgiving. It was going to be 5 weeks before a new motor would be delivered. We purchased four of these heaters and placed them strategically throughout our 2300 sq ft home. We had several nights that the outdoor temperature was below freezing. We were able to keep our home between 66°-68°. This type of heater radiates heat slowly, but very consistently. It puts out a lot of heat and is designed for large rooms.

Warms very well. Completely reliable.

Six years ago, I bought a Mainstays oil filled heater from Walmart. It has worked wonderfully. I found myself needing a second one in our two-story house and immediately I remembered how well ours has worked. It has been reliable and warms very well. It is so simple to operate.
