Breaker trips when using two space heaters in different rooms at same time

According to the Panel box, two of my upstairs bedrooms feed into the same circuit, i.e., same breaker switch control the power for both. This hasn't really been an issue until we recently discovered that if an electric space heater is in use in both rooms (i.e., 2 concurrently running), the circuit breaker would always trips The trip actually would not blow right away, just sometime in the middle of the night. Is there anything that I (or an electrician) can do for this problem?

Yep, run a new circuit to one of the rooms.

One space heater can pull most of the available current from a 15 amp circuit. Many heaters on high are 1'500 watts. The working capacity of a 15 amp circuit is about 1'440 watts (which is 80% of 15 amps) which limits you to one heater per circuit.

You might try turning the heater down to the lowest setting temporarily. Normally there is a full 1500W and a half power setting.

I agree though, if this will be an ongoing thing or the heaters need to be on high all the time, dedicated lines are called for.

I have to say this...you should never run any sort of portable heater when people are sleeping. Most have tip-over controls and such...but it's still not safe.

You really need dedicated circuit. General purpose receptacles are daisy chained. When you pull high amps like a heater a poor connection can start a fire if the breaker doesn't trip in any of the receptacles not just the one your using. That could be a room you seldom enter. The fire could be well established before you even realize it.

I would get rid of the electric heaters and use the central furnace.

As stated you need dedicated circuits. Better would be hard wired baseboard heater.

Thanks all. I'll leave the circuits alone.

Also, we do rely on the central furnace, however, we also wanted (at least one of) these rooms to be slightly warmer than the rest of the house hence the space heaters.

Do you have two available spots on your panel to have an electrician add a 20 amp circuit to each room?
I like having the extra warmth control in a room as well. There are plenty of safe devices to use in a room. The important thing is to have the room powered properly to support those devices.
If you have the space in your panel or if you just don't know; definitely consider asking an electrician to check it out, get advice.
Be as comfortable as you wish to be. That's what our homes are for. Just be sure to have it done right.

Good Luck! Stay warm and cozy.
