Why does my 1500 watt heater consistently blow my 15 amp breaker fuse?

At 120 Volts your heater is drawing about 12.5 Amps. If your house only had 120 V then it would draw 13.6 Amps.
Problems could be
1.) Other devices on same circuit.
2.) Internal short in the heating element that reduced resistance and increased current.
3.) Faulty heater in that it really delivers more than 1500 watts because heating elements are less resistance than rating would require.
4.) Faulty breaker.
These are in order of likelihood. You are close enough to the limit of the breaker that it could be any of these things. Typically you should not exceed 80% of the breaker rating and that is just where you are operating.

A 1500-watt heater draws approximately 12.5 amps, which is close to the 15-amp capacity of the breaker. If there are other appliances drawing power on the same circuit, it could easily trip the breaker. You may need to run the heater on a circuit with fewer devices drawing power to prevent overloading the breaker.

WHY DOES MY blow heater keep tripping out your electrics?
Your blow heater may be drawing too much power, causing the circuit to overload and trip the breaker. It could also be a sign of a faulty electrical connection or a problem with the heater itself. We recommend having a qualified electrician inspect the heater and wiring to determine the exact cause of the issue.
Why will too many electrical devices operating at one time after blow a fuse or trip a circuit breaker?
The load exceeds the limit of the breaker or fuse. For example a 20 amp breaker on a 120 volt circuit will handle 2400 watts. Exceed that wattage and the breaker will trip or the fuse will blow.
Can you conect your dryer to a heater circuit?
Not advisable. Both units consume huge amounts of Amps (amperes = current) and the normal 20 or 30 amp breaker may not sustain prolonged operation of both. Where I live, we have two electric meters ... one just for the water heater, the other for the house and all it's electrical needs (except for the water heater).
Can too much current on a breaker cause it to blow up?
High current on a breaker can cause it to trip or cut off power to prevent overheating and potential fire hazards. If the current exceeds the breaker's capacity for an extended period, it may damage the internal components and cause the breaker to fail, but not "blow up" in the traditional sense.
Will your spa work with a 40 amp breaker even if it says 50 amp on the plate?
No, because if you switch a 50-amp load on, it will blow a 40-amp circuit breaker if the load exceeds 40 amps, which is likely.

Only if you leave the burners or elements on. -If water stops, close gas line or switch off breaker for tank.
Why does the heater not blow air?
The heater does not blow air because it emits infrared rays that have heat molecules within them, thus releasing heat, not blowing it. A heater does not blow air becasue there is no moving air source within the heater. The heater emits infrered rays that cause heat to slowly flow out of the heater.

What would cause a 98 dodge 1500 4x4 heater to blow luke warm air?
Any heater that only blows luke warm air isn't getting warm or hot water to the coil. This sounds like a problem with the thermostat not closing, and allowing the engine to heat the water properly for the heater.
