Best value good quality, fast shipping. Highly recommended
Bought a used Hardy wood furnace that came with two exchangers. Unfortunately both were left in the cold and cracked rendering useless. We purchased this unit due to the best price out there and free shipping, not expecting much when it arrived it looked exactly like the one we needed, installed it the next day and it works spectacular. 2 days in use and blowing serious heat. Time came quickly and priced right Cardinal Classics NE-AR

Good quality unit
I connected this to our wood boiler heater lines and I mounted a 20" box fan behind it, controlled by a thermostat controller, and use it to heat our 15'x25' greenhouse. Works great and the greenhouse stays toasty warm all winter!

Good replacement.
I needed to modify my casing for the unit, but worked out great. I heat a 32x40 pole barn well insulated. I have no complaints about the unit.
