About Us

Jim Langley,
Owner/ Operator

I have been an electronic engineer for over 40 years getting my experience working on a diverse spectrum of electronics in silicon valley, california. I enjoy fishing, boating and electronics. My father told me in high school 'get into electronics, jim-that's the future of america!' he was so right too, look how electronics has truly made our lives easier.



Now retired, I started heatwave electronics when a friend called me saying: "Jim, my mom's pellet stove is dead and I can't afford to buy her a new one and they no longer repair or offer any replacement parts for her antique stove...Please help me!!!" I repaired her 'stove computer' in my garage, at no charge, and suddenly by word of mouth his friends with pellet stoves and their friends became my friends. True story.

Customers Review


I had a hard time finding a controller for my Whitfield pellet stove. Everyone wanted 500.00 or more to replace the board. I sent the controller to Heatwave and had it back in days and they not only fixed the problem but replaced a switch that was hard to turn. I could not have been happier with their work. 150.00 and the stove is better than ever. I highly recommend this company to anyone that needs work done to their board/controller. Any work that I may need in the future will start at this company.

Quality Service

The control panel arrived here about a week ago and the Whitfield has been cranking out BTUs ever since. Thank You for the quality service.

Jim, just wanted to let you know our little Whitfield is humming away and finally making HEAT. I was pretty sure I had an electrical connection or sensor problem and, after reading Jim’s email and through the literature he sent me, I started tracing down the various leads and discovered that the repair tech had not replaced the low-temp switch and the auger power connection in the proper location on the terminal block. It never occurred to me that he would have done that wrong.

– Thanks again, Ted

Thanks Again

I just wanted to drop you a line and say thanks again. I attached a couple of pics of the 1995 Whitfield Cascade stove I rebuilt, before and after. It worked out fine as you can see by the couch couger in the second pic. I referred you to the parts manager at my local stove dealer, they are a pretty big outfit and he was happy to have your contact info and also a few friends who have board issues and I will continue to pop up.

– Thanks, Dan
