I just went on the Northern Tool website to check some specs. on the Heatstar 75K heater I just ordered. To my surprise, website says unit is no longer available. Not sure how I feel about not even having a product delivered yet that has been discontinued.
Called Enerco, maker of Mr. Heater Big Max, and Heatstar, and they say they are discontinuing the 75K models and replacing them with 80K models. Not sure what the reasoning would be for that.
Anybody wanting a 75K model had better hurry, since there are still a few Mr Heaters on Northern's website, but at a higher price. That may be why they were running a special to move the Heatstar 75K's, and I got the last one
