Understanding Electricity Consumption
Before we dive into the topic of whether a space heater uses more electricity than central heat, it’s essential to understand electricity consumption and how it is measured. Electricity consumption is the amount of energy used by an electrical appliance in a given amount of time. The unit of measurement for electricity consumption is watts, and the time it is used is measured in hours. Therefore, the unit of measurement for electricity consumption is watt-hours (Wh).
- Watts (W): A unit of measurement of electrical power that measures how fast energy is being used.
- Kilowatts (kW): A unit of measurement that represents 1000 watts.
- Kilowatt-hours (kWh): A unit of measurement that represents the energy used by a 1000-watt appliance for one hour.
It’s important to note that the cost of electricity is measured in kWh. Therefore, the more electricity consumed by an appliance, the more expensive it is to run.
Factors That Affect Electricity Consumption
Several factors affect electricity consumption, including:
- The power rating of the appliance: The higher the power rating of an appliance, the more electricity it consumes.
- The duration of use: The longer an appliance is used, the more electricity it consumes.
- The frequency of use: The more often an appliance is used, the more electricity it consumes.
- The efficiency of the appliance: The more efficient an appliance, the less electricity it consumes.
When considering the electricity consumption of heating systems like space heaters and central heating, several factors come into play that can affect energy consumption.
Comparison of Space Heaters and Central Heating Electricity Consumption
