Wattage of the heater ÷ 110v = Amps Needed
(example 1250 watt heater ÷ 110v = 11.36 amps) so one 1250 watt heater on a 15 amp circuit.

It depends on the heaters and on the circuit. A 15 amp circuit can support a total of 1800 watts. A 20 amp circuit can handle 2400 watts. Look on the heaters for the rating. And don't forget, anything else already on the circuit must be figured in.
Forget that 80% rule, it does not apply to your general use receptacle outlet circuits.

Take the total wattage and divide it by the voltage used will give you the amps needed to run the heaters. On a 20 amp circuit you can only use 16 amps and on a 30 amp circuit you can only use 24 amps. You are only allowed to use 80% of the circuit breaker.

Check the AMP limit of the circuit and AMP draw of the heaters

Check AMP limit - usually heaters are 20 AMP - 30 AMP and most of the residential breakers are not more then 20 AMPS so its safe just to have one.
Get an electrician.
