Q: Are electric heaters cost-effective in Bangladesh winters?
A: Electric heaters are expensive (৳3,000-6,000/month). Use passive heating: solar gain during day, thermal clothing, hot water bottles (৳50-100/month), and insulation. You can save 80-90% on heating costs with smart alternatives.
Q: When should I run major appliances to save money?
A: Use time-of-use pricing: run washing machines, dishwashers, and water heaters during off-peak hours (11 PM-6 AM) for 20-30% savings. Avoid peak hours (6-10 PM) when electricity rates are highest.
Q: How often should I maintain my AC during different seasons?
A: Summer: Clean filters every 2 weeks, check for leaks monthly. Monsoon: Weekly filter cleaning, inspect for water damage. Winter: Monthly check, annual professional servicing. Proper maintenance improves efficiency by 15-25%.
Q: What's the most effective way to manage load shedding?
A: Pre-cool rooms to 24°C before cuts, close doors to trap cool air, use battery fans, prepare ice blocks for cooling. Invest in UPS systems (৳8,000-15,000) for essential appliances. Plan cooking and other activities around load shedding schedules.
