That massive spike of 50c/kWh at the left looks tiny compared to today even though that’s already insanely expensive
Bruh, a space heater is the least efficient way to heat a space, unless electricity somehow costs less per MWh than gas (that is insanely cheap and only true in a few key places in the world).
Also dehumidifiers… don’t do what you think they do? They are basically an A/C unit, that dump the hot air in the room they sit in. Literally worse than nothing.
*Re-*humidifiers have marginal benefits in (very) dry weather as evaporation is endothermic. As soon as the air is even somewhat humid though, they’re literally worse than nothing again.
It’s not inefficient if it makes you feel warm. Often you don’t really need to warm everything in a house to be comfortable. It might make sense to do so in a situation when electricity goes out/grid is unreliable and you don’t have a thermal battery to ride on for a few hours, or you want to keep your water pipes warm enough so they don’t freeze.
But I know a lot of people who choose to forego so much heating, keeping their space to like <15/59, and have a heated blanket or space heater/fireplace entertainment center.
Feel like this works best in a shared living situation though, like an apartment or town home. For detached situations, maybe it does make sense to keep things relatively warm in case of emergencies.
They were talking about consistently heating a whole room though. I guess there’s a case to be made if the thermostat for the central gas heating is in another room and can’t be moved… But you should probably organize your heating so that this is a corner case (which is why the thermostat is typically in the living room in detached living. Other rooms don’t usually need to be kept particularly warm).
Of course if you have a badly insulated house and no way to properly distribute the central heating or to pay to heat the whole space to 18 °C, use resistive if you must. But that goes against everything that central heating is supposed to be for.
Also you really should not let a building go under 15 °C. It depends on the specifics (insulation, ventilation), but you’re liable to get mold or other kinds of water damage due to condensation.
Good points. There are a variety of houses/buildings built during various periods of time according to various codes and standards, but if you’re within city limits (US/Canada) then your house was probably built after the 70s/80s and has decent insulation. If there is an issue with the central heating in that kind of home, I 100% agree that there’s an issue that you might want a GC to fix. If your house/building is old, or if landlords don’t want to fix shit (and complaints are too much of a hassle), then I can also see that space heating can be a reasonable bandaid: at least until you get out of that situation.
Condensation is something I also forgot. That’s important for you electrical system too. In my experience in electric distribution/collection, usually we’d want to keep termination points around 20/68, but thermostats could drop to as low as 10/50 before kicking in. Certainly keeping a house colder than 10/50 is a bad idea, but between that and normal 20/68 I’d think would be fine. You also have the risk though that your thermostat is a single point of measurement for the system. Other parts of a house might be cooler/warmer, so I’d agree with the advice to keeping your house warmer than 15/59, unless it supports multi-unit dwellings.
Good convo, cheers
