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
- "Classical" heat pump: https://www.youtube.com/watch?v=MFEHFsO-XSI
- Cheaper & easier: AC heating / Heizen mit Klimaanlage
- Without installation (for tenants / Mieter)
- Heat blanket / Heizdecken
- Portable AC (?): https://www.youtube.com/watch?v=aYHQzQQwSn4
- Infra-red heating: https://www.youtube.com/watch?v=qw4X44h2Jk4
- 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)
