This page collects discussion on practical heating / energy saving advice, including controversial issues.

Heating by electricity

  • Generally, generation of electricity has only 30-50% efficiency.
  • However, using electrical device on well-defined time slices can be more efficient than heating an entire room.

Shall I use an electrical radiator / convector?

  • overall electrical energy available: 830W as per 582000000000000KWh/80000000/24/365/h
  • Question: can it be connected to a smart grid?

Electrical heating graded by efficiency

  • With installation
  • Without installation (for tenants / Mieter)
    • Heat blanket / Heizdecken
    • Portable AC (?): https://www.youtube.com/watch?v=aYHQzQQwSn4
    • Radiators (more efficient, because in addition to heat they also convey energy via radiation)
    • Convectors
    • Heat fan / Heizlüfter
    • in principle, electrical heatings cannot be inefficient, as every use of electricity generates heat (e.g. you also could mine bitcoins, or alternative, support writing this wiki on your computer)
