Great for RV

 from NV– Verified Buyer– Top 100 Reviewer

If you fulltime in an RV, you know about cold days & nights. Maybe you want to warm the bedroom before showering, or maybe you want to warm your tootsies while watching DWTS. This Portable Buddy will do the trick for short bursts of heat.

 from Fort Wayne, IN

Great to have if you ever have to go without heat. This model in particular really kicks out the heat. We live in a drafty old farm house & this big buddy heats up the whole downstairs in a matter of 10 minutes. The little propane tanks are reasonably priced and last a long time.
The only downer for this product, if you choose to hook up a cylinder tank, it can't be inside because of the fumes.
I highly recommend this product. What if you had to go without your furnace?

Manufacturer Details
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.
