We often blame the AC for our sky-high electricity bills, but there’s another silent culprit that might be consuming even more energy — and most people don’t even realize it!
Your electric water heater (or boiler) is often the biggest energy hog in your house. Why?
Here’s why it quietly drains your electricity:
- It runs constantly. Unlike the AC, which turns off and on based on need, many water heaters maintain a hot water reserve 24/7 — even when you’re not using it.
- Old or uninsulated tanks lose heat rapidly, forcing the system to work harder to maintain temperature.
- Long hot showers, washing clothes with hot water, or even running the dishwasher on a hot cycle — all add up fast.
How much does it actually consume?
- A typical electric water heater can use 3,000 to 4,500 watts per hour.
- If left on all day, it can consume more electricity than running an AC for 6–8 hours.
Tips to reduce its impact:
- Turn it off when not in use, especially at night or when you’re away.
- Install a timer or smart plug to control when it runs.
- Use cold water for laundry when possible.
- Insulate the tank and pipes to reduce heat loss.
- Consider switching to an energy-efficient or tankless water heater.
Your wallet will thank you — and so will the planet.
Know your real energy hogs. It’s not always what you think!
