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.

Works as advertised. Great heater %26 value.

Works as advertised. Great heater %26 value. I own three which were purchased for two bedrooms and a living room. Our HVAC heating unit failed in mid-January 2026 during the big freeze, snow %26 ice storm and these heaters were lifesavers. They are nice to have around in case of emergency. I like these so much that I also purchased three for my daughter to use as emergency heating back-up at her home.

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.
