Portable Heater Honeywell Wave

We used to have a Honeywell Ceramic Wave heater, and it went out at the end of last winter. In seeking a new one, I came across the Honeywell Wave that has 1500 watts. Can we use this in a 30 amp motorhome, or should we just buy the same one we had with lower watts? Anyone know the difference between the regular model and this one? Thanks so much for any help.

1,500 watts is 12.5 amps . So, yes you can use it in a 30 amp RV. However, it will use over a third of your available amperage when running full blast.

As bentjm says, a 1500 watt heater is a big chunk of your available power (30A - 3600 watts). If you run that heater on High, that is. It probably has a low heat mode that is 800-1000 watts that you could use.

The potential problem is that you leave other appliances in electric mode. If those appliances have a thermostat, you may not realize they are switching on/off all the time and thus randomly will cause a circuit breaker trip if the heater is also on. Refrigerator and water heater are the man worries, but you can put those in LP gas mode to reduce the electrical load.

Not positive but I bet the OP's old ceramic heater was rated at 1500 watts when set on high. The same is probably true for the newer heater that the OP is looking at. As said, it will run on a 30 amp circuit. A person just has to be careful not to turn too much other stuff on at the same time.

Gary mentioned the thermostat on the heater,, Yes, wife had the microwave going when the thermostat on the heater called for heat. Those 2 things, along with probably the 450 watt water heating element cycling on at the wrong time, caused the circuit breaker to trip. You just have to be mindful of what all's running.
