Comment on Price of electricity in Finland peaks at 2.35€/kWh today. Keeping my tiny granny cottage warm costs me over 50 euros for a single day. It's negative 25C (77F) outside.

  All space heaters operate at the same efficiency since they convert electricity to heat via resistance. You may have a small one and low electricity rates in your area to see a negligible change. Or maybe other uses went down and masked the increase from the space heater usage.

    Almost. Some are better at heating people, others are better at heating air

  Bruh I don’t think you understand how electricity consumption works.

  A space heater will pull a given wattage, say 1000 watts for a pretty common one. Electric heaters are 100% efficient meaning 100% of the energy going in is converted to heat, so running that 1000 watt space heater for 1 hour will consume 1000 watt-hours (or 1 kilowatt hour) and heat the space by exactly 1000 watts or 1 kilowatt (kilo meaning thousand)

  Plugging this into a electric bill calculator, at a common $0.15/kWh running that 1000 watt space heater 24/7 will cost about $100 per month

  If your space heater is so insanely awesome, please do tell me, what’s your electric rate and the wattage of the heater?

    Bruh, I don’t think you understand that heating a room is cheaper than heating your whole house.

    My electric bill is ~$160 when running the central heater. It’s ~$80 when I run my space heater.

    As always, I encourage people to see for themselves rather than trusting strangers on the internet.

    Experience is better than theory, every time.

      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.
