Book ServiceWhat Is a Tankless Water Heater?
A tankless water heater, sometimes called an on-demand water heater, heats water only when you need it. When you turn on a hot water tap, cold water flows into the unit, where a gas burner or electric element heats it instantly as it passes through a heat exchanger. Because there’s no storage tank, there’s no reservoir to run out and no energy wasted keeping 50 gallons hot around the clock. Tankless units mount on a wall and take up a fraction of the space of a traditional tank. They also last longer, often 20 years or more with proper maintenance. Over the last decade, many Loganville homeowners have moved from tank to tankless for these reasons.

Benefits of a Tankless Water Heater
With a tankless water heater, the last person in line for a shower gets the same hot water as the first. You can run the dishwasher, start a load of laundry, and fill the tub without planning around a tank that’s running low. And because the unit heats water only when you use it, you’re not paying to keep a big tank of water hot while you sleep or travel. It’s an upgrade that pays off in comfort, space, and savings for years:
- Continuous hot water that doesn’t run out, even during busy mornings
- Lower energy use, since there’s no standby heat loss from a storage tank
- A much longer lifespan, often 20 years or more compared to 8 to 12 for a tank
- Space savings from a compact, wall-mounted unit
- No risk of a tank rupturing and flooding your garage or attic
- Steady water temperature without the fluctuations of an aging tank
Types of Tankless Water Heaters and How to Choose
The right tankless system depends on your fuel source, how much hot water you use at once, and your home’s setup. Here’s what we look at:
- Gas tankless water heaters: higher flow rates for whole-home use, ideal for homes with natural gas or propane
- Electric tankless water heaters: simpler venting needs, but they may require an electrical panel upgrade
- Condensing models: capture extra heat from exhaust gases for higher efficiency
- Non-condensing models: lower upfront cost with traditional venting
- Whole-home units: supply hot water to every fixture in the house
- Point-of-use units: small units that serve a single bathroom or sink far from the main water heater
We size your system by flow rate, measured in gallons per minute, based on how many showers, sinks, and appliances run at the same time. An undersized unit is the most common reason people feel disappointed with tankless, so we take time to get it right.

Should You Switch From Tank to Tankless?
If your tank water heater is still in good shape and meeting your needs, there’s no rush to replace it. But when your tank is 10 years old or more, leaking, or regularly running out of hot water, it’s a great time to consider tankless. Switching at replacement time means you’re only paying the difference in upgrade cost, not replacing a working unit.
For existing tankless units, repair usually makes sense when the issue is a sensor, igniter, or scale buildup. Replacement is worth considering when a unit is near 20 years old or the heat exchanger has failed. Either way, we’ll lay out the costs of each option so you can choose what works for your home.
Tankless Water Heater Considerations in Loganville Homes
Loganville homes come in all ages and layouts, and each one has its own needs when it comes to going tankless. Older homes were built around tank water heaters, so a conversion often involves a few upgrades. Winter cold snaps also bring colder incoming water, which affects how much hot water a unit can deliver at once. Here’s what we commonly address:
- Gas lines that are too small to supply a tankless unit’s fuel demand
- Venting that needs to be replaced or rerouted for a gas tankless unit
- Electrical panels that need an upgrade for an electric tankless system, handled by our electrical team
- Scale buildup in the heat exchanger when maintenance is skipped
- Circuit boards damaged by storm-related power surges
- Units sized too small to keep up with colder winter water temperatures
