Water heating is one of the biggest energy expenses in any home. In fact, for many households, it can account for up to 20% of your utility bills. Beyond cost, inefficient water heating wastes energy and can contribute to unnecessary carbon emissions.
The good news? There are practical ways to save energy, lower your bills, and extend the life of your water heater — without sacrificing comfort. Here are the energy-efficient water heating tips that every homeowner should know.
1. Lower Your Water Heater Temperature
Many homeowners keep their water heaters set to 140°F out of habit. However, most households only need 120°F for everyday tasks like showering and washing dishes.
✅ Benefits:
- Reduces energy use by up to 10%
- Slows mineral buildup in your tank
- Reduces risk of scalding
Most water heaters have an easy-to-adjust thermostat — check your owner’s manual for guidance.
2. Insulate Your Water Heater and Pipes
Heat loss from your water heater and the pipes leading to your taps is a major source of wasted energy.
✅ Tips:
- Wrap older tank water heaters in an insulating blanket
- Insulate hot water pipes with foam sleeves
- Focus on the first 6 feet of pipe coming out of the heater
This simple step can reduce heat loss and lower energy bills without any major investment.
3. Upgrade to a High-Efficiency Water Heater
If your water heater is more than 10–12 years old, it’s likely using far more energy than modern models.
✅ Options:
- Tankless (on-demand) water heaters — heat water only when needed
- Heat pump water heaters — highly efficient for homes in moderate climates
- Solar water heaters — great for sunny regions
Modern energy-efficient units can cut your water heating costs significantly over time.
4. Fix Leaks Promptly
Even a small leak from a faucet, showerhead, or the water heater itself wastes hot water — and energy — every day.
✅ Quick Tips:
- Check for dripping faucets and running toilets
- Inspect the tank for signs of corrosion or leaks
- Call a licensed plumber if you notice persistent leaks
Stopping leaks is one of the simplest ways to conserve water and energy.
5. Use Less Hot Water in Daily Routines
Small behavioral changes add up.
✅ Ideas:
- Take shorter showers or install a low-flow showerhead
- Run dishwashers and washing machines full loads only
- Wash clothes in cold or warm water instead of hot
These changes reduce energy use and water consumption without sacrificing convenience.
6. Consider a Water Heater Timer
If your household has predictable hot water needs, installing a timer on your water heater can cut unnecessary energy use during off-peak hours.
✅ Benefits:
- Automatically turns off the heater when it’s not needed
- Can save hundreds of dollars per year
- Works with both tank and tankless models
Conclusion
In conclusion, implementing energy-efficient water heating tips can significantly reduce your utility bills while also contributing to a more sustainable environment. From lowering your water heater temperature to upgrading to a high-efficiency model, each step you take not only optimizes energy usage but also enhances your overall comfort at home. It’s important to avoid an undersized water heater, which can be overworked and lead to higher energy costs. By making informed choices and being proactive about maintenance, you can enjoy the benefits of hot water without the hefty costs. Remember, every small change counts!

Frequently Asked Questions
Is it better to keep my water heater set to a lower temperature for energy savings?
Yes, it is highly recommended. Lowering your water heater thermostat from 140°F to 120°F can reduce your water heating costs significantly. This simple adjustment on your electric water heater saves energy, minimizes the risk of scalding, and slows down corrosion in your water heater tank and water heating system.
Are tankless water heaters more energy-efficient than traditional models?
Yes, tankless water heaters are more energy-efficient. Unlike conventional water heaters that constantly use energy to keep a water tank hot, tankless models heat water on demand. This eliminates standby heat loss, reducing energy consumption for water heating by 24% to 34% in homes with moderate hot water use.
How do energy-efficient water heaters help the environment?
A high-efficiency water heater, such as a heat pump water heater, consumes less energy to operate. This reduction in energy use, especially from fossil fuels, means fewer greenhouse gas emissions are released into the atmosphere. By lowering your home’s carbon footprint, you contribute to a cleaner, more sustainable environment.
Which ENERGY STAR water heater models save the most energy?
Among ENERGY STAR water heater models, heat pump water heaters typically offer the greatest energy savings, potentially using up to 60% less energy than a standard electric water heater. Gas-powered tankless water heaters are also highly efficient, providing significant savings by eliminating standby losses associated with water heating.
How much money can I expect to save each year by upgrading to an energy-efficient water heater?
Upgrading to an energy-efficient water heater can save you between $100 and $200 annually on your utility bills. Models like tankless water heaters can save between $70 and $80 per year, while heat pump systems can save even more, making it a wise long-term investment for your water heating system.
