Heat Pump Dryer Running Cost Calculator
Heat-pump tumble dryers can use less electricity per completed load than many condenser or vented models, but the size of that saving depends on the exact appliance, programme and load. If your dryer shows a kWh-per-cycle figure on its energy label, use that when comparing models rather than relying on generic wattage ranges.
Use the power for your appliance and the time it actually runs. This estimates a continuous draw; use measured kWh when you have it.
Cost per hour£0.26
Cost per session£0.66
Energy per session2.50 kWh
Weekly£2.63
Monthly£11.41
Annual£136.86
Formula: watts ÷ 1,000 × hours × electricity rate. The rate is in pence, and results are shown in pounds. Monthly = weekly × 52 ÷ 12; annual = weekly × 52. Standing charges are excluded.
What the result means
- Heat-pump dryers often use longer, lower-temperature cycles, so rated wattage alone does not tell you completed-cycle energy use.
- Energy-label or measured kWh-per-cycle data is the better basis for comparing specific dryers when available.
- Cycle duration varies by load size, fabric type and selected programme.
- The calculation covers electricity use only and excludes purchase price, maintenance and other ownership costs.
