    About the Manufacturer

    Mr. Heater's parent company, Enerco Group Inc., is a Cleveland, Ohio company. The business began as a side business venture for a large manufacturer of plastic extrusion equipment. At the time, Al Haire was an outside sales representative for Enerco's overhead radiant heaters. He saw great potential in the business, and when the original owners decided to spin off the Enerco business in 1982, Al bought the company.

    In 1986 Enerco launched Mr.Heater to bring portable radiant heaters to the consumer markets. Over the next 20 years the Mr.Heater product line has grown to be one of the most complete in the industry. The business grew… but they have never drifted from their roots and values.

    Today about 100 people work in their modern headquarters facility. This 150,000 square foot facility is our primary manufacturing and distribution center, and also houses our business offices and our engineering and quality departments.

    In additional to product innovation and quality manufacturing, Mr. Heater has built a reputation on after-sale support and sincere customer service. Every customer phone call and e-mail received is answered by a trained employee. From choosing a product, to maintenance procedures and parts… their team is there to support the people who support them!

    Great heating unit.

    Rogue from Calgary, AB

    It's being used in a 14' x 24' insulated detached garage, and even on the lowest setting it's able to keep it more than warm enough on a cold winter day. It's quite easy to use, and nice to have this winter. The blue flame is the best way to go for this application.
