Your water heater is one of the biggest energy users in your home, accounting for up to 30% of utility costs. Old, inefficient models can really drive up your energy bills. By optimizing your water heater settings and maintenance, you can maximize efficiency and savings.
Follow these 10 tips:
1. Lower the Temperature Setting
Turn down your water heater's temperature setting to 120°F or lower. This prevents excessive heating beyond what's needed for comfortable use. For each 10°F reduction, you can save up to 5% on water heating costs.
2. Use a Water Heater Blanket
Insulating your water heater with a water heater blanket reduces standby heat loss, allowing it to operate more efficiently. Ensure it fits snugly and covers the top and sides. DIY kits start around $20. Proper installation is key.
3. Drain Sediment Regularly

Drain a quart of water from the tank's bottom valve annually to flush sediment that impedes heat transfer and traps heat. Instructions are in your manual. Doing this extends your water heater’s life.
4. Install Heat Traps
Installing heat trap fittings on the hot and cold supply lines prevents convection heat loss up the pipes.
5. Insulate Pipes
Insulating exposed hot water pipes with pre-split foam tubing maintains water heat as it travels to fixtures. This reduces the amount of re-heating needed.
6. Use Flow Restrictors

Installing low-flow showerheads and faucet aerators reduces the amount of hot water used. Less water used means less energy needed for heating. Look for WaterSense certified models.
7. Fix Dripping Faucets
Just one dripping faucet can waste hundreds of gallons monthly requiring constant heating. Fixing leaks saves water and the energy to reheat more.
8. Shorten Showers
Taking shorter showers saves gallons of hot water and the energy needed to heat more. Just shaving 1-2 minutes can make a difference.
9. Wash Full Loads
Run full loads in your dishwasher and clothes washer to maximize the hot water used per cycle. That means more efficient water heating rather than heating water for partial loads spread out.
10. Upgrade If Old
If your water heater is more than 10 years old, replace it with a new energy-efficient model to reap savings on your utility bill. Each unit has an expected lifespan.
With some simple adjustments, maintenance, and everyday usage habits, you can operate your water heater in the most efficient, cost-effective way possible. Be diligent to maximize savings.
How Your Water Heater Works
To understand how to optimize efficiency, it helps to know the basic operation of home water heaters:
Water heaters have a storage tank that is constantly filled with pressurized water from your home's main cold water supply line. Inside the tank, gas burners or electric heating elements heat the water.
A thermostat and thermometer regulate temperature. As hot water leaves the tank when you use a fixture, cold supply water enters to re-fill the tank and be heated. This cycle continues 24/7 to ensure hot water is ready when needed.
Losing heat from the tank, pipes, or usage waste makes your heater work harder, using more energy. Optimizing efficiency minimizes this waste.
Water Heater Types and Efficiency Comparison

Two main types of water heaters include:
Conventional Storage Tank
An insulated tank constantly maintains a set volume of hot water ready for use. Natural gas or electric heating.
Tankless On-Demand
Heats water only as demanded. More energy efficient but endless hot water has tradeoffs.
Here is how the efficiencies of different models compare:
- Electric storage tank - 90%+ efficient
- Natural gas storage tank - 65-80% efficient
- Tankless gas condensing - Up to 98% efficient
- Tankless electric - 99% efficient
While tankless models are most efficient, proper maintenance optimizes any hot water heater.
Checklist to Diagnose Water Heater Inefficiencies
Notice any of these signs? Your water heater may be operating inefficiently:
- High energy bills from increased gas or electric use
- Hot water runs out quickly during showers or use
- Rumbling, popping, or percolating sounds
- Drips or leaks from tank, valves or pipes
- Long wait times for hot water at fixtures
- Discolored/stained water
- Rust accumulation on exterior or from taps
Don't ignore inefficiency symptoms. A service checkup can identify underlying issues.
Protect Components That Impact Efficiency

Key water heater parts that impact efficient operation include:
Insulation – Retains heat. Ensure jacket insulation is dry and fully surrounding tank.
Burner/Heating Elements – Transfer energy efficiently into the water. Replace if corroded or mineral-caked.
Thermostat – Maintains optimal temperature. Calibrate or replace if readings are off.
Relief Valve – Releases excess pressure. Must be rated to tank temperature/pressure.
Anodes – Curb corrosion. Inspect and replace magnesium/aluminum anode rod when depleted.
Gaskets – Seal in heat. Replace cracked inlet/outlet gaskets allowing heat loss.
Take proactive steps to maintain components that directly influence efficiency.
Be Smart About Water Heater Location
Where you install your water heater impacts efficiency:
- Centrally located near water use points to minimize pipe distances and heat loss.
- Install in conditioned indoor spaces, not outside rooms subject to elements.
- Ensure adequate clearance for ventilation, servicing and insulation access.
- Keep the area clean and dry to prevent corrosion and insulation mold.
Take the location into account when installing a new unit or considering relocating your existing heater. This small factor makes a difference.
New Efficient Water Heater Options
When buying a new water heater, look for energy-saving features:
- Heat pump models extract heat from surrounding air.
- Hybrid heat pump + storage tanks balance efficiency and hot water capacity.
- Condensing technology recycles heat exhaust.
- Integrated mixing valves for tempering hot water as needed.
- Improved insulation like foam covers.
- Larger tanks store more pre-heated water.
