Nobody likes a cold shower, especially during a chilly Pacific Northwest morning. But keeping your water heater running efficiently while managing your energy bills can be a delicate balance. The good news is, you don’t have to give up comfort to save money.
With a few smart habits and some simple maintenance, you can make your water heater last longer, waste less energy, and still enjoy that perfect hot shower. Whether you have a traditional tank model or one of the newer tankless water heaters, these tips can help keep your system performing its best.
Tip#1: Adjust the Temperature Setting
Most hot water heaters are set to a factory default temperature of around 140 degrees Fahrenheit, but in most homes, that’s hotter than necessary. By lowering the temperature to about 120 degrees, you can significantly reduce your energy use without noticing a difference in comfort.
Why does this matter? Heating water accounts for nearly 20% of the average home’s energy bill. Reducing the temperature means your unit doesn’t have to work as hard to keep gallons of water hot all day long. Plus, lower settings help slow mineral buildup and corrosion, extending your unit’s lifespan.
When you adjust the thermostat:
- Check both thermostats if you have an electric unit—one near the top, one near the bottom.
- Avoid going below 120°F, which could allow bacteria to grow inside the tank.
- Test the temperature at a faucet after making the change to make sure it’s comfortable.
A small tweak like this can lead to steady monthly savings and safer, more consistent water temperatures.
Tip#2: Flush Your Water Heater Regularly
If you’ve never drained or flushed your unit before, you’re not alone. Many Oregon and Washington homeowners overlook this simple maintenance task, but it’s one of the most effective ways to keep your system efficient. Over time, sediment and minerals, especially in areas with hard water, settle at the bottom of the tank. That buildup forces the heating element to work harder, wasting energy and shortening the heater’s life.
Here’s how to maintain your tank properly:
- Turn off power or gas before starting.
- Attach a hose to the drain valve at the bottom of the tank.
- Let the water flow out until it runs clear of debris.
- Close the valve and refill the tank before turning it back on.
Experts recommend flushing your water heater once or twice a year, depending on your water quality. For tankless water heaters, the process is slightly different, involving descaling to remove mineral deposits. If you’re not sure how to do it safely, you can always call Henco for professional water heater services.
Tip#3: Insulate the Tank and Pipes
If you’ve ever touched the side of your traditional water heater and felt it radiating warmth, that’s heat loss—and it’s costing you money. Adding an insulating jacket or blanket around the tank can reduce standby heat loss by up to 45%, depending on the model and age of your unit.
In addition, insulating the first few feet of hot water pipes that come out of the heater helps maintain higher water temperatures for longer, reducing how often the heater needs to cycle on.
When insulating:
- Use fiberglass or foam insulation rated for high temperatures.
- Avoid covering thermostats or burner areas.
- Wrap exposed pipes, especially in unheated basements or garages.
- Secure insulation with tape or zip ties to keep it snug.
These small upgrades are inexpensive, easy to do, and can lead to noticeable savings, particularly during colder months.
Tip#4: Repair Leaks and Drips Quickly
A slow drip from your faucet might not seem like a big deal, but over time it adds up, both in wasted water and wasted energy. Even a tiny leak in a hot water line means your heater has to keep reheating water that’s constantly being lost.
Common sources of leaks include corroded fittings, loose pipe connections, or worn seals. The most serious leaks often occur around the tank itself, which can indicate rust or internal failure.
Here’s how to stay ahead of the problem:
- Inspect visible pipes and connections every few months.
- Check the pressure relief valve for moisture or small leaks.
- Listen for hissing or dripping around the tank or floor drain.
- Schedule professional water heater repair or replacement if you notice ongoing issues.
Fixing leaks right away keeps your heater efficient and helps you avoid costly water damage later on.
Tip#5: Consider Your Type of Water Heater
Not all water heaters are created equal, and your model has a big impact on both efficiency and comfort. If your current system is more than 10 to 12 years old, upgrading to a newer or more efficient design could cut your water heating costs dramatically.
Here’s a quick breakdown of your main options:
- Traditional water heaters (tank models): Store and heat a set amount of water. Reliable, but less efficient over time.
- Tankless water heaters: Heat water on demand for endless hot water and lower energy use. Great for smaller households or efficiency-minded owners.
- Gas or electric water heaters: Each has pros and cons depending on your utility rates and home setup.
If you’re constantly running out of hot water, or if your unit seems to run nonstop, it might be time for an upgrade. The team at Henco can help you choose an efficient water heater that fits your home, budget, and comfort needs.
Tip#6: Schedule Professional Maintenance
Even the best-kept systems need a tune-up from time to time. Scheduling annual maintenance for your water heater is one of the easiest ways to keep it efficient, safe, and reliable. A professional plumber can catch problems early, like worn parts, loose connections, or small leaks—that you might not notice until they cause a breakdown.
During a maintenance visit, technicians typically:
- Inspect heating elements or burners for efficiency and safety.
- Check the anode rod (which prevents corrosion in the tank).
- Test thermostat accuracy and water pressure.
- Clean sediment buildup or flush the system if needed.
Routine maintenance can extend the life of your unit by several years. Whether you have a newer tankless model or an older storage-style heater, keeping it serviced regularly ensures it runs efficiently and safely through every season.
Tip#7: Use Hot Water Wisely
Even if your system is running perfectly, you can still save money with a few smart habits around the house. Reducing hot water demand lowers both your energy and water bills without affecting your comfort.
Try these simple changes:
- Install low-flow showerheads and faucets to reduce usage without changing water pressure.
- Run full loads in your dishwasher and laundry machines.
- Fix leaky taps as soon as possible.
- Use cold water for washing clothes whenever possible.
- Turn off water when brushing teeth or shaving.
These small daily habits can add up to big savings over the course of a year—and they make your household more sustainable, too.
Tip#8: Know When to Replace Your Water Heater
Every water heater eventually reaches the end of its life. When repairs start becoming frequent, or if your system struggles to maintain consistent temperature, it’s often more cost-effective to replace it entirely.
Signs it might be time for replacement include:
- Rust-colored water coming from your taps.
- Rumbling or popping sounds from the tank.
- Leaks or moisture collecting around the base.
- High energy bills with no clear cause.
Newer efficient water heaters use better insulation, smarter heating elements, and advanced designs to minimize waste and maximize comfort. Whether you’re considering gas, electric, or tankless options, upgrading can provide better performance while lowering your energy costs.
