Heizung
In short
A heating system provides warmth to a building by transferring thermal energy to the indoor air or surfaces.
In plain words
It is a way to keep a house or office warm during cold weather. Most systems use electricity, gas, or oil to heat water or air, which then flows through pipes or vents.
A simple example
A central heating system uses a boiler to heat water. This hot water travels through radiators in every room to release warmth.
Why it matters
Reliable heating is essential for human health and comfort in cold climates. Modern systems also focus on being energy-efficient to save money and protect the environment.
Easy to mix up
Do not confuse a heater, which warms a single small area, with a heating system, which warms an entire building.
