Switching to a Tankless Water Heater in East Memphis (Is It Worth the Investment?)
If you live in East Memphis and your water heater is over 10 years old, you are probably paying for hot water you never use. Tankless water heaters heat water only when you need it which means no more wasted energy keeping 40 or 50 gallons hot 24/7. In East Memphis where many homes range from 1960s ranch styles to newer builds, the switch can free up closet space and cut utility bills by 20 to 30 percent. The real question is whether the higher upfront cost makes sense for your home and your family’s hot water needs..

East Memphis homes built before the 1980s often have 4000 to 5000-watt electrical panels that cannot handle the 27000-watt load a whole-house electric tankless requires. Gas models need a dedicated 3/4-inch gas line and proper venting to the outside. If your home runs on a 1/2-inch line you will need a line upgrade. Shelby County Code Enforcement requires a permit for any water heater replacement and the unit must meet Energy Star efficiency standards. MLGW offers rebates up to $450 for qualifying gas tankless models but only if installed by a licensed plumber who pulls the permit. MLGW rebate program.
Hard water in Memphis means tankless units need annual descaling to prevent mineral buildup in the heat exchanger. Without maintenance, efficiency drops and the unit can fail in as little as five years. A water softener can extend the life of your investment but adds another $1200 to $1800 to the project cost. For a family of four in a 2000-square-foot East Memphis home, a tankless system providing 8 to 10 gallons per minute is usually enough to run two showers plus a dishwasher at the same time..

Why Tankless Works for East Memphis Homes
East Memphis has hard water with high mineral content that builds up in traditional tank heaters causing them to lose efficiency in just a few years. Tankless units avoid this by heating water instantly through a small heat exchanger. Because there is no storage tank, you never run out of hot water during a long shower or when the washing machine is running. For older ranch homes with limited utility space, a wall-mounted tankless can free up 16 to 20 square feet of floor space..

Local water pressure in East Memphis averages 45 to 65 psi which is ideal for tankless performance. If your home has older galvanized pipes, pressure drops can occur. A plumber can test your flow rate with a simple GPM gauge to confirm your home can support a tankless system.

Installation Requirements and Local Codes
Shelby County requires a permit for any water heater replacement. The permit ensures the unit meets National Fuel Gas Code requirements for gas models or National Electrical Code for electric units. Venting must extend at least 12 inches beyond the building exterior and terminate away from windows and doors. Condensate from condensing units must drain to an approved waste line or exterior drain.
MLGW inspects gas lines for leaks before service is restored. If your home has a 1/2-inch gas line and the new unit requires 3/4 inch, the plumber must run new pipe from the meter. This can add $500 to $1000 to the project. Electric tankless units need a dedicated 240-volt circuit with breakers sized to the unit’s amperage draw. Older East Memphis homes may need a service panel upgrade.
Call (901) 640-3313 before you buy. We will confirm your home meets all code requirements and handle the permit process for you.

Energy Savings and Rebates for Memphis Homeowners
Tankless units rated by Energy Star use 27 to 50 percent less energy than standard tanks. In Memphis where electricity costs average 11 cents per kilowatt-hour, a family using 60 gallons of hot water per day can save $150 to $200 per year. MLGW offers rebates up to $450 for qualifying natural gas tankless models installed in 2026. You must submit the rebate form within 90 days of installation.
Federal tax credits for Energy Star water heaters expired at the end of 2023 but may return in 2026 under new legislation. Keep your receipt and the model’s Energy Guide label in case credits become available again. Some tankless brands also offer their own instant rebates through local distributors.
Call (901) 640-3313 to find out if your home qualifies for MLGW rebates and to get a free energy savings estimate.
Choosing the Right Size for Your Home
Gallons per minute flow rate determines the size you need. A typical East Memphis bathroom faucet uses 1 to 1.5 GPM while a shower head uses 2 to 2.5 GPM. A washing machine adds 2 GPM and a dishwasher 1.5 GPM. Add up the fixtures you might run at the same time to find your peak demand.
For a family of four in a 2000-square-foot home, an 8 to 10 GPM gas unit or a 27 kW electric unit usually handles two showers plus a dishwasher. If you have a large soaking tub or plan to run multiple showers during morning rush hour, step up to a 10 to 11 GPM model. Undersized units cause lukewarm water when demand spikes.
Call (901) 640-3313 and we will calculate your exact GPM needs based on your home’s fixtures and usage patterns.
Maintenance Tips to Protect Your Investment
Tankless units need annual descaling in Memphis due to hard water. A plumber uses a food-grade citric acid solution to flush the heat exchanger and remove mineral buildup. Skipping this step can reduce efficiency by 30 percent and shorten the unit’s life to five years instead of 15. Some homeowners install an inline water filter to reduce sediment before it reaches the heater.
Clean the inlet screen every six months to prevent clogs. Check the vent cap for debris and ensure the condensate drain is clear. If you notice fluctuating water temperature, it may be time for a professional flush. Most manufacturers require proof of annual maintenance to keep the warranty valid.
Call (901) 640-3313 to schedule your annual tankless maintenance and keep your warranty in force.

The higher upfront cost pays for itself through lower utility bills, space savings, and longer unit life.

Frequently Asked Questions
How long does tankless installation take in East Memphis?
Most installations are completed in one day. The plumber will mount the unit, run new gas or electrical lines, install venting, and test the system. If gas line or electrical upgrades are needed, the project may take two days.
Do I need a water softener with a tankless heater?
Not required but highly recommended in Memphis due to hard water. A softener prevents mineral buildup in the heat exchanger and can extend the unit’s life by five to ten years.
Can I install a tankless unit myself?
No. Tennessee law requires a licensed plumber to install any water heater. DIY installation voids the warranty and can create safety hazards with gas or electrical connections.
What if my home has a septic system?
Tankless units produce minimal condensate, usually less than one gallon per hour. The condensate can drain into your septic system without issue. If local code requires it, we can run a separate drain line to the yard.
Will a tankless unit work during a power outage?
Gas tankless units need electricity for the control board and ignition. Without power, they will not operate. You can add a small battery backup for the control board if power outages are common in your area.
