Endless Hot Water
Tankless units heat water on demand, so you do not run out during back-to-back showers, laundry, or dishwasher cycles.
Upgrade to endless hot water with professional tankless water heater installation, replacement, and repair in Memphis and surrounding Shelby County communities.

Tankless systems cost more upfront, but many Memphis-area homeowners choose them for endless hot water, efficiency, space savings, and a much longer service life.
Tankless units heat water on demand, so you do not run out during back-to-back showers, laundry, or dishwasher cycles.
Because there is no stored tank of hot water, tankless systems avoid standby heat loss and can reduce water-heating energy use.
Wall-mounted tankless units free up valuable floor space in garages, utility rooms, closets, and mechanical areas.
A well-maintained tankless unit can last 20 years or more, often outlasting a conventional tank by a wide margin.
Tankless systems are built from replaceable components, which can make long-term maintenance and repairs more practical.
They work especially well for households with high hot-water demand or homeowners who value efficiency and space savings.
Compare long-term ownership costs before deciding which system fits your home.
| Gas Tankless | Gas Tank | Heat Pump / Hybrid | |
|---|---|---|---|
| Installed Cost | $2,500–$6,500+ | $1,300–$2,000 | $2,500–$5,000+ |
| Monthly Cost | Varies | Varies | Lowest |
| Lifespan | 20+ yrs | 8–12 yrs | 13–15 yrs |
| Hot Water Supply | Continuous | Limited by tank | Limited by tank |
| Space Required | Very Low | Moderate | Moderate / High |
| Maintenance | Annual descaling | Periodic flushing | Filter / condensate care |
Operating cost varies with current utility rates, household hot-water usage, equipment efficiency, fuel type, and system size.
Tankless systems are sized by flow rate, not tank volume. Your plumber will calculate simultaneous fixture demand and incoming water temperature.
| Household / Demand | Recommended Flow | Typical Fit |
|---|---|---|
| 1 bathroom / 1–2 people | 4–6 GPM | Small condensing unit |
| 2 bathrooms / 3–4 people | 6–8 GPM | Most common Memphis installation |
| 3+ bathrooms / 5+ people | 8–11+ GPM | High-capacity gas tankless |
Memphis-area winters bring colder incoming water temperatures, so tankless units have to work harder than they do in warmer climates. Proper sizing is especially important if multiple showers or appliances may run at the same time.
A tankless conversion is more involved than a standard tank replacement. These are the main items your plumber evaluates.
Most whole-home gas tankless units require a larger gas line than a conventional tank. Your plumber will verify meter and line capacity before installation.
Condensing tankless units typically use PVC venting through an exterior wall or roof. Proper termination clearances are required.
High-efficiency condensing models produce acidic condensate that must be routed to an approved drain, often through a neutralizer.
Gas tankless systems still need 120V power for controls, ignition, freeze protection, and the internal fan.
Memphis-area water varies by community and source. Annual flushing helps protect the heat exchanger from mineral buildup and keeps performance and efficiency at their best.
Tankless conversions generally require plumbing permits and may involve gas, venting, and electrical inspection requirements.

A tankless water heater heats water only when you need it, so there is no standby energy loss from keeping a tank hot all day. For Memphis-area homeowners with high hot-water demand or limited space, tankless is often an excellent long-term investment — though the upfront cost is higher than a standard tank.
Gas tankless units ($2,500–$6,500+) deliver high flow rates and are the most common whole-home choice where natural gas service is available. Electric tankless units ($1,500–$4,000+) are compact and efficient but require 150–200 amp electrical service — many older Memphis-area homes have 100–150 amp panels and would need an upgrade first. Point-of-use electric tankless units can work well for a single fixture without a panel upgrade.
Both are high-efficiency upgrades, but they solve different problems. Tankless provides endless hot water on demand and frees up floor space. A heat-pump (hybrid) tank ($2,500–$5,000+) is the most efficient electric option and can offer the lowest operating cost for all-electric homes, with the added benefit of potential incentives. Eligible MLGW customers may currently qualify for a $900 TVA EnergyRight retail coupon toward select ENERGY STAR certified heat-pump water heaters at participating retailers. Eligibility, qualifying models, participating retailers, and incentive amounts can change, so confirm current program terms before purchase. Qualifying units may also be eligible for other utility, manufacturer, or state incentives. The right choice depends on your fuel availability, hot-water demand, and whether you prioritize endless flow or maximum efficiency.
Tankless units need annual descaling to flush mineral buildup from the heat exchanger. Memphis-area water hardness varies by community and source, but regular flushing still protects efficiency and extends the unit's 20+ year lifespan. Most manufacturers require documented annual maintenance to keep the warranty valid.
