One of the most frequent questions Singapore homeowners ask before upgrading is: “Will an automated smart laundry rack cause a spike in my monthly SP Group electricity bill?” The direct answer is no—smart racks are remarkably energy-efficient compared to traditional tumble dryers.
Energy Consumption Breakdown by Mode
Smart racks utilize efficient DC motors and low-wattage LED lights. Power consumption varies depending on which features you run:
| Function / Feature | Power Wattage | Average Cycle | Est. Cost Per Cycle* |
|---|---|---|---|
| Lifting Motor (Up/Down) | 50 Watt | 30 seconds | < S$0.01 |
| Tri-Tone LED Light | 24 Watt | 4 hours/day | S$0.03 |
| Twin Fan Blowers | 35 Watt | 2 hour timer | S$0.02 |
| Dual Thermal Heat Drying | 450 Watt | 2 hour timer | S$0.28 |
*Calculated using standard Singapore electricity tariff rates (~S$0.31 per kWh).
Smart Rack vs. Tumble Dryer Monthly Comparison
Assuming a family runs 4 heavy washing loads per week (16 drying cycles per month):
- Conventional Tumble Clothes Dryer (~2500W): Approx. S$25.00 – S$38.00 monthly.
- Smart Automated Laundry Rack (~450W Heat): Approx. S$3.50 – S$6.50 monthly.
The Verdict
Upgrading to a smart laundry system delivers over 75% in electricity savings compared to a tumble dryer, while avoiding heat shrinkage and fabric wear!
