I was wondering if anyone else used this product to test heat exchangers.
H.E.A.T. (heat exchanger analyzer tester)
Basicly, for those not familiar with this product, you spray the product into the blower compartment opposite the blower for 45 seconds. If the heat exchanger has a hole in it, the spray will alter the flame pattern. Fairly simple I guess, I was just wondering if anyone else used this stuff.
