To quote my earlier comment with emphasis this time:
The only ways a space heater is more efficient is if either you’re spending a shitton of energy heating rooms you aren’t in or if your homes heating system is in bad need of repair/replacement
So you’ve already agreed with my original point, because you reduced power consumption by turning your HVAC down and using a space heater to heat just the room you’re in. Running a 4 kilowatt central heater will use more electricity as it runs than a 1 kilowatt space heater. But a 1 kilowatt space heater is still pulling down a kilowatt to run (which is a lot!)
Experience is better than theory, every time. I feel sorry for the people who will avoid saving money because of comments like yours.
YOU CAN LITERALLY CALCULATE THIS! Watts consumed by the heating source multiplied by number of hours per month it runs gives you the watt hours for power consumption, bigger number means bigger bill. In fact it’s important to calculate it first because electric bills will naturally fluctuate and be difficult to identify the changes in consumption due to being an aggregate of everything in your home combined with outside temperature fluctuations.
