- Price, the warranty and what a link pays us stay out of it.

“I was torn on this review as I had a technical issue with one of the two heaters that I purchased. One worked flawlessly and the other would blow breakers when running on high. Fortunately, Thermomate came through and is replacing the bad unit at no cost about 6 months after purchase. It is a nice product (when working) and pumps out good heat. I'll update this review after I get a few months use out of it (has only been turned on twice) and if the second unit works well, I'll upgrade this review to 5 stars. More shortly!”— SteveinMA, Amazon · Verified owner
