A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

If a machine is never 100% efficient transforming energy into work because part of the energy is converted into heat, does it mean an electric heater is 100% efficient? [@showerthoughts@lemmy.world](h (social.graves.cl)

But there's a flip side to that as well - if you've got heat pump heating your whole home but you only really need to heat 1 room, you may be "wasting" a good chunk of that bonus efficiency.

If you dont want certain rooms heated you close the doors to those rooms. And place the heater such that the airflow goes trough the rooms you want heated.

Also the house should be heated evenly unless you have really poor isolation and that should be addressed way before the minutia of heat pumps gets discussed.
