Easily I would think, appliances use a crapload of power so 1375w isn't all that much in a 4br. Shoot, my snake room uses that much by itself: you got all the heat sources for their thermoregulating needs, the lights for each cage(optional on nocturnal animals), climate controls(A/C, heat, humidity; all on thermo/hydrostats), 9cft freezer for the food, etc. That's just one of 4 br in the house and I've had that for years with no issues or suspicions.
