Modine's hot dawg - Great heater!

We’ve had this a couple of years now. It’s great when the temperature is freezing out and you want to work in the garage. Or, if you want to warm up your car a little, only done that a couple of times with sub-zero temperatures.

Reznor, I love it !

Very nice, well built,looks good, works great! a+++. When first got thought fan looked small compared to other units, but worked very well & more quiet then thought. Nice product!

Happy with my hot dawg

Works like a champ. Heats my shop in about 13 minutes and cycles with t-stat to keep temperature.

- Santellano

Great heater for years. No problems at all

Has worked great for many years with zero problems. I installed this into a garage and it really works great, heats the garage quickly and is very efficient on fuel. Bought it from and had it installed by a long time professional heating contractor who has installed lots of these and says they never have a problem if installed correctly. You really need to have someone who understands how these heaters work and can install them correctly.
