There seem to be several problems with the stated specs.

First, either the power rating (1450 watts) is wrong, or the stated current (12.5 amps) is wrong. The formula is Volts x Amps = Watts. If the heater really draws a current of 12.5 amps, then the correct wattage is 120 x 12.5 = 1500 watts. Or if the heater power is really 1450 watts, then the actual current would be 1450/120 = 12.08 amps.

Second, a given heater does not have output rated in BTU (British Thermal Units). The correct rating is BTU/hour. So the stated spec of 6500 BTU has to be wrong... it's the wrong units.

Third, what's the actual heat output? The correct formula is: watts x 3.412 = BTU/hour. If the actual wattage is 1450 watts as stated, then the correct heat output is 4947 BTU/hour. Or if the wattage is 120 volts x 12.5 amps = 1500 watts, then the heat output would be 1500 x 3.412 = 5118 BTU/hour.

In NO case is the heat output 6500 BTU/hour!

And there is NO SUCH UNIT as "Heat Units." This whole ad is BOGUS!
