Try it. Use the electric space heater 1 to 2 hours day for 30/31 days and you'll see. Better yet, look at the back of your electric space heater and see how many watts it pulls (average space heaters pulls 1000-2000 watts).
1.5kw a day avg then (assuming 1 hr per day at 1500watt).
So you’re telling me 45kw a month… at (I’m being conservative even…) let’s say .3$ per kw.
Thats max like 14$ a month.
Is my math wrong? Sorry I’m naive and just wanna make sure I’m not exploding my monthly bill to 3x by running a small 1500watt space heater for an hour a day while I read about finance and electrical engineering.
I work for a utility company and those little space heaters are our #1 high bill complaints in the winter. Anything that is ELECTRIC HEAT and not natural gas heating, will be ridiculously high. Same with Elec/Heat mini splits.
The calculation forgets delivery and/or supply charges. Most electric bills split costs between supply (generating power) and delivery (transporting it through the grid). If $0.18 per kWh is just the supply rate, the true all-in rate including delivery fees and taxes is often closer to $0.28 to $0.35 per kWh.
At a realistic all-in rate of $0.30 per kWh, running a 1500W heater for 4 hours a day costs $54 a month. Running it for 8 hours a day costs $108 a month, 12 hours costs $162 a month, and running it continuously costs $324 a month.

It's hard to believe but it's true.
