I have an electric heater connected to the same plug extension as my computer, but when my computer goes to sleep, when i turn my heater on and off it wakes my computer from sleep, is this normal?

Go into Windows' Device Manager, find your mouse and check if it is enabled as a wake-up source. Your computer might be coming out of standby due to mouse movement from vibrations when the fan starts.

But as Poprin said, you shouldn't plug high-powered appliances like heaters into extensions. If you absolutely have to, make sure it is a genuine UL-listed one with #14 gauge real copper wires from a reputable brand. If you buy dollar store extensions, you may end up with cables marked #14 that are actually #16 or even #18 copper-clad aluminum which can be fire hazards.

You shouldn't really plug things like electric heaters into multi-plug mains adapters. They pull way too much wattage. It's clearly not normal behaviour, as you turn the heater on it's clearly causing a power drop which is more likely causing your computer to loose power. If in BIOS your machine is set to reboot on power loss it's actually more likely that the machine is temporarily loosing power, crashing and rebooting rather than simply turning itself back on.
