    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!

    Steven from Midland, NC– Verified Buyer

    The heater was installed in place, tested and operational withing 2 hours from the start of the installation. It fired right up as the directions indicated it would and has been able to maintain a constant heat throughout my greenhouse by itself and one additinal circulation fan. No longer am I getting up every four hours to check the wood stove and the wild swings in the heat from the refiring of the wood stove to the burn down. I am getting sleep this winter! GREAT PRODUCT!

    A decent heater

    warmer in NJ from EHT, NJ

    Replaced a propane open flame heater in a 500sf basement room with this NG heater. Heats room in around 30-45 minutes from 60 to 70 deg. Used as a suplement heater. Fan is a bit noisy but can be shut off. Produces a little odor but not as bad as that propane heater. Customer service from Mr. heater was good as I emailed them with a question and they responded wihth 2 days.
