Temperature settings: The 5-minute fix that saves $200+ yearly
Why 120°F is the magic number
Most water heaters come factory-set at 140°F, but most households never need water that hot for any daily activity. Lowering your setting to 120°F reduces energy consumption by 6-10% while still providing perfectly comfortable hot water for showers, dishes, and laundry.
Here’s the math: A typical Sandy household spending $40 monthly on water heating can save $4-8 monthly just from this temperature adjustment. That’s $48-96 yearly for a 5-minute change that most homeowners never make.
We recently helped a West Jordan family who was surprised to discover their water heater was set at 150°F – hot enough to cause scalding injuries. Reducing it to 120°F cut their gas bill by $23 monthly while actually making their hot water safer for their young children.
How to adjust your water heater temperature safely
For electric units, you’ll typically find two thermostats behind removable panels. Always turn off the circuit breaker before removing these panels – you’re working with 240-volt electricity that can be dangerous.
Gas water heaters usually have a simple dial near the bottom of the unit. Look for temperature markings and turn to 120°F or the “medium” setting if specific temperatures aren’t marked.
After adjusting, wait 24 hours before testing water temperature at your fixtures. Hot water should feel comfortably warm but not scalding. If it’s not hot enough for your preferences, you can adjust upward slightly, but each degree costs money.
Insulation upgrades that pay for themselves in months
Small upgrades like insulation blankets and pipe wraps can dramatically improve your water heater’s efficiency. These low-cost improvements pay for themselves in just months while helping your system deliver hot water faster and use less energy every day.
A Draper family added simple pipe insulation in their basement, cutting heat loss and improving delivery time. Hot water reached their upstairs bathroom 15 seconds faster, and they noticed lower gas costs on their very next bill—proof that affordable efficiency upgrades can create instant savings.
Water heater blankets: $30 investment, $100+ yearly savings
Older water heaters lose significant heat through their tank walls, especially units manufactured before 2004. Adding an insulation blanket reduces this standby heat loss by 25-45% on older units.
You can buy water heater blankets at any hardware store for $20-30. Installation takes about 30 minutes and requires no special tools – just wrap it around the tank and secure with the provided tape or straps.
Be careful around gas units – never cover the top, control panel, or any venting components. Electric units can be wrapped more completely but should leave access to heating element panels for future service.
Pipe insulation: The overlooked efficiency booster
Insulating the first 6 feet of both hot and cold water pipes reduces heat loss during water transport and can improve hot water delivery time. This is especially effective in unheated basements or garages where pipes lose heat to cold air.
Foam pipe insulation costs about $1 per foot and slips right over existing pipes. Focus on hot water pipes first, but insulating cold water pipes prevents condensation and slightly reduces the work your water heater does by delivering warmer incoming water.
A Draper family saw immediate improvement after insulating their basement pipes. Hot water reached their upstairs bathroom 15 seconds faster, and they noticed the improvement on their very next gas bill.
Smart usage strategies that compound your savings
Smart adjustments in how you use hot water can multiply your savings without sacrificing comfort. From timing appliance use during off-peak hours to installing efficient low-flow fixtures, these simple strategies reduce energy costs, lower water bills, and often pay for themselves in just months.
Timing hot water activities strategically
If you have time-of-use electricity rates, running hot water appliances during off-peak hours saves money. Many utility companies charge 50% less for electricity used overnight or during mid-day periods.
Consider running dishwashers and washing machines in the evening or early morning when possible. Even with standard rates, concentrating hot water usage helps tankless systems operate more efficiently and reduces standby losses for tank systems.
Low-flow fixtures: Comfort without waste
Modern low-flow showerheads and faucet aerators maintain excellent water pressure while reducing hot water consumption by 30-50%. The EPA’s WaterSense program certifies fixtures that meet performance standards while saving water and energy.
These upgrades typically cost $15-40 per fixture and install in minutes with basic tools. The water savings translate directly to energy savings since you’re heating less water for the same daily activities.
We helped a Sandy family replace their old showerheads with efficient models, and they immediately noticed the difference on their utility bill. The $60 investment in new fixtures paid for itself in less than three months.
Maintenance habits that preserve efficiency
Annual sediment flushing: Essential in Utah’s hard water
Sandy’s mineral-rich water creates sediment deposits that insulate heating elements from direct water contact. This buildup forces your water heater to work harder and consume more energy to achieve the same heating results.
Annual sediment flushing removes these deposits and restores efficient heat transfer. For most homeowners, this is a job for professionals since it requires shutting off power/gas, draining the tank, and potentially removing stubborn buildup.
However, you can minimize sediment buildup by occasionally running hot water at your fixtures until it’s steaming hot. This stirring action helps prevent settled minerals from hardening into efficiency-robbing layers.

Upgrade opportunities that maximize efficiency
Heat pump water heaters: 60% efficiency improvement
If you’re ready for a major efficiency upgrade, heat pump water heaters use ambient air temperature to help heat water, reducing energy consumption by 50-60% compared to traditional electric units.
These systems cost more upfront but qualify for significant utility rebates in Utah. The energy savings often pay back the investment in 3-4 years while providing the same reliable hot water you’re used to.
Drain water heat recovery: Capture waste heat
These systems capture heat from shower and washing machine drain water to preheat incoming cold water. In homes with frequent hot water use, drain heat recovery can improve overall efficiency by 10-15%.
Installation requires plumbing modifications and professional expertise, but the energy savings continue for decades. This upgrade makes most sense during bathroom remodels or new construction when drain lines are already being modified.

When efficiency improvements aren’t enough
Signs your water heater needs professional attention
Steadily rising bills despite efficiency efforts
If your utility costs keep climbing even after implementing efficiency measures, internal problems like sediment buildup or failing components need professional diagnosis.
Longer recovery times
When your water heater takes increasingly longer to provide hot water after heavy usage, efficiency-robbing problems are developing that maintenance can often resolve.
Age-related efficiency decline
Water heaters naturally become less efficient as they age, especially units over 8-10 years old. If efficiency improvements don’t restore reasonable performance, replacement might be more economical than continued operation.

Advanced efficiency strategies
Smart water heater controls
Programmable controls let you reduce water heater temperature during times when hot water isn’t needed, like overnight or during work hours. These systems can reduce energy consumption by 10-15% in households with predictable usage patterns.
Some smart controls learn your family’s usage patterns and automatically adjust temperature settings to minimize energy waste while ensuring hot water is available when needed.
Solar pre-heating systems
In Utah’s sunny climate, solar water heating systems can provide 50-80% of your hot water needs during peak sunshine months. These systems work alongside your existing water heater, reducing the work your primary system needs to do.
While solar installation requires significant upfront investment, federal and state incentives can offset much of the cost, and the energy savings continue for decades.
Recirculation systems with timers
Hot water recirculation systems eliminate the wait for hot water at distant fixtures, but they can waste energy if they run continuously. Timer-controlled systems provide instant hot water when you need it without constant energy consumption.
These systems work particularly well in larger homes where hot water travel time is significant. The convenience factor often justifies the modest energy cost, especially when controlled by smart timers that learn your usage patterns.
