Running a dehumidifier can often reduce heating costs because dry air warms up faster and holds heat better. This leads many people to ask which option is cheaper.
Cost comparison
- Typical dehumidifier: six to twelve pence per hour.
- Central heating: much higher depending on boiler and gas rates.
Why a dehumidifier can save money
- Dry air heats more efficiently.
- Rooms feel warmer at the same thermostat setting.
- Condensation reduces, preventing heat loss through windows.
Best way to use both together
Run the dehumidifier for one to two hours in the morning or during laundry drying. Then reduce the heating slightly. Most homes do not need to run both at the same time for long.
Dehumidifiers are not a replacement for heating, but they often reduce how much heating you need.
