Is it more economical to keep the global temperature lower like 18° C and use space heaters to boost that where its immediately needed to be warmer? (lemmy.world)

EDIT- My heating/ac is all electric so i cant do anything about that or gas and i cannot install a heat pump most likely because i rent and probably cant change large aspects like that

I'd like to have two space heaters (one i already have as a floater between bedroom and living room, its a small apartment)

Is it possibly more efficient and cost-saving to keep a minimum temperature to keep the "pipes" from freezing in winter but be able to surgically modulate the temperature using seperate slace heaters like if i stay in either room all day just use that room's sh to get it comfortable but let the other room just chill at the min temp

If your regular heating is electric anyway, then yes obviously.

Electrically heating a small space uses less energy than electrically heating a big space, that's fairly trivial.

How much less energy depends on how big your entire home is vs. the areas you'd heat with space heaters.

The most efficient solution would probably be IR heaters, as those heat you directly, as opposed to the air, meaning you can keep them off and let the room cool when you're not using it, and turn them on to make you feel warm almost immediate when entering a room, without the need to heat/keep warm the entire room, but that only works when you're staying in more or less the same spot for long periods of time, if you're moving around a lot an IR heater won't do much.
