The Mr. Heater® name is known and trusted by millions of people. This trust has been earned through years of hard work and integrity.

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 grew to be one of the most complete in the industry. The business grew, but has never drifted from their original roots and values.

Today about 100 people work in Mr. Heater's modern headquarters facility. This 150,000 square foot facility is the primary manufacturing and distribution center, and also houses business offices and their engineering and quality departments. Mr. Heater also selectively imports products from Europe and Asia to meet their customers' needs. All of these products are designed in Cleveland and inspected to meet Mr. Heater's requirements and quality standards.
