Water heaters are a crucial part of everyday life, but at Benitez Plumbing, we know they can quietly push monthly energy costs higher than they need to be, especially in Rockville Centre’s cool-weather climate, where units cycle longer and mineral scale forms faster. The good news is that small changes can deliver big savings. That is why we assembled this friendly guide filled with 10 practical water heater tips ranging from quick habit tweaks to smart equipment upgrades, giving you clear, actionable ways to cut waste, boost efficiency, and enjoy reliable hot water all year.
Understanding Your Water Heater and Local Conditions
Quick Overview of the Types of Water Heaters
Before diving into our 10-tips list, it helps to know the type of water heater you have. Most Rockville Centre homes rely on one of two main styles: traditional storage tanks or modern on-demand (tankless) units. Each behaves a little differently regarding energy use, lifespan, and upkeep, and understanding these basics will make the following tips much easier to apply.
Tank Water Heaters
A tank heater is the big metal cylinder you often see in basements or closets. It holds 30 to 80 gallons of water and keeps it hot all day with gas, propane, or electricity. Because it reheats water even when no one is using it, some energy is wasted while the water just sits there, making it a less energy-efficient option compared to tankless heaters.
Tankless Water Heaters
On the other hand, a tankless (on-demand) heater is a compact box mounted on a wall. It stays off until you open a tap and then quickly heats water as it flows through, so there’s no storage tank and almost no standby energy loss. However, the flow can slow down if too many fixtures run at once.
When you compare the two side by side, tankless units usually win on three factors: they waste less standby heat, cost less to run month after month, and have a greater lifespan than a standard tank. Conventional storage tanks, on the other hand, win on upfront price, capacity, and flow rate.

Local Conditions in Rockville Centre, NY
It is also important to know how local conditions impact efficiency and your water heater system’s lifespan. Rockville Centre’s municipal water comes from Long Island’s sandy aquifers, picking up natural minerals (like calcium, magnesium, and iron) on the way to your tap. As a result, the local water is moderately hard, which means mineral scale buildup is a common issue.
These local conditions affect both conventional tank and tankless water heaters (whether gas or electric). In tank-style heaters, hard water minerals tend to settle and form sediment layers at the bottom of the tank or on the electric heating elements. This rock-like scale insulates the water from the heat source, forcing the heater to work harder and longer to reach the set temperature, increasing water heating costs.
Tankless systems are not immune to hard water issues either—in fact, they require just as much attention. A tankless heater has narrow passageways in its heat exchanger coil, which heat the water on demand. Hard water minerals can accumulate as limescale on the heat exchange coils or even clog the flow sensors and narrow ports.
Our Top 10 Tips to Save Money and Energy
1. Reduce Your Overall Use of Hot Water
While this might seem obvious, reducing the overall use of hot water is the easiest energy and water-heater-saving tip. You can take shorter showers, consider switching to water-sensing faucets, run full loads in your dishwasher, and even decide to use cold water in your washing machine, as it is unnecessary for the laundry to come completely clean.
2. Lower Your Water Heater Temperature
Many heaters ship at 140°F, but most homes do well at 120°F. That setting helps prevent scalds and reduces energy use. It can also slow mineral buildup, which shortens equipment life. Lowering the dial earns a big percentage in annual water-heating savings, making this one of the simplest water heater efficiency tips around.
3. Don’t Skip Your Water Heater Maintenance
A monthly five-minute visual check can catch rust, drips, or a stuck temperature-and-pressure (T&P) valve, giving you time to schedule professional repair before disaster strikes. For tankless units, routine descaling keeps flow rates strong, which is especially important in hard-water neighborhoods.
4. Schedule Yearly Plumbing Inspections
An annual visit lets a licensed plumber spot early issues before they become emergencies. It’s also the moment to confirm your thermostat setting, review hot-water demand, and match your equipment to your household’s size and routines.
5. Drain Your Tank Yearly
Sediment accumulates at the bottom of tank-type heaters. That layer forces the burner or elements to work harder, raising energy bills and wear. Flushing the tank once a year clears the gunk so heat transfers efficiently and the tank runs quieter. If your home has hard water, ask whether a six-month flush makes sense.
6. Repair Leaks Immediately
Even “tiny” drips add up. A hot-water leak wastes both water and the energy you paid to heat it. Fixing leaks, replacing worn washers, and addressing running fixtures can make a visible difference on your utility bill.
7. Be Mindful of Your Water Heater’s Lifespan—and Consider Replacing It
If your tank is nudging ten years old, it’s time to plan to replace it. Corrosion risk, reduced efficiency, and surprise floods all spike after the decade mark. Budgeting ahead lets you choose an efficient replacement on your schedule and not in a midnight emergency.
8. Replace Old Appliances
Old washers and dishwashers can waste a lot of hot water, increasing energy bills. If you’re upgrading appliances, this is one of the easiest water heater saving tips that doesn’t even touch the heater itself.
9. Insulate Your Tank
Add a water-heater blanket or insulation system if your electric tank feels warm to the touch. Upgrading tank insulation can cut standby heat loss by roughly 25–45% and save about 7–16% on water-heating costs.
10. Consider Switching to a Tankless Water Heater
Tankless heaters only warm water when needed, so you avoid paying to keep a tank hot all day. That design can reduce energy use and deliver “endless” hot water within the unit’s flow limits. If your existing tank is aging or undersized, a tankless upgrade is worth a look.
