Practical Energy Savings Tips

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

• Heizdecken
• radiators are more efficient, because in addition to heat they also convey energy via radiation
• convectors
• 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)
