How Tankless Water Heaters Work
A tankless water heater heats water as it is needed rather than storing a large supply of hot water in a tank. When a hot-water fixture is opened, water flows through the unit and is heated by a gas burner or electric heating element.
Because the system does not continually heat and reheat stored water, it can reduce standby energy loss. A properly sized tankless system can also continue producing hot water without running out in the way a traditional tank does. The amount of hot water it can provide at one time is still limited by the unit’s flow rate and the temperature of the incoming water.
The U.S. Department of Energy provides additional information about how tankless water heaters operate and how their efficiency compares with conventional systems.
Benefits of a Tankless Water Heater
Continuous Hot Water
A properly sized tankless water heater can provide a continuous supply of hot water. This can be useful for larger households, homes with soaking tubs, or families that frequently use several hot-water fixtures.
Continuous does not mean unlimited at every fixture simultaneously. The system must have enough capacity to meet the household’s peak demand. Proper sizing is one of the most important parts of a successful tankless installation.
Compact Design
Tankless water heaters are mounted on a wall and take up considerably less space than traditional tank-style units. Depending on the home’s layout and installation requirements, switching to tankless may free up part of a garage, basement, utility room, or closet.
Reduced Standby Energy Use
Traditional water heaters maintain a stored tank of hot water throughout the day. Tankless systems operate only when hot water is requested, which can reduce energy use. Actual savings vary based on household usage, fuel costs, equipment efficiency, and the condition of the existing water heater.
Long Service Life
A well-maintained tankless water heater can often last 20 years or longer. Actual lifespan depends on the quality of the equipment, installation, water quality, household demand, and maintenance history.
Tankless Water Heater Installation in Lilburn
A tankless installation involves more than removing a traditional water heater and mounting a smaller unit in its place. The new system must be matched to the household’s hot-water demand, fuel supply, venting requirements, plumbing layout, and installation location.
Aaron Services evaluates the complete setup before recommending equipment. Our goal is to install a system that can meet the home’s needs without paying for unnecessary capacity.
Proper Tankless Sizing
Tankless systems are sized according to flow rate and the amount of temperature rise required. We consider:
- The number of bathrooms and people in the home
- Fixtures that may use hot water at the same time
- Incoming groundwater temperature
- Desired hot-water temperature
- The home’s gas or electrical capacity
- Pipe layout and distance to frequently used fixtures
- Recirculation needs
An undersized unit may struggle when several fixtures are used at once. An oversized system may cost more than necessary without providing a meaningful benefit.
Gas, Propane, and Electric Options
Gas-powered tankless water heaters are commonly used for whole-home applications because they can provide higher flow rates. Before installation, the existing gas line must be evaluated to determine whether it can support the new unit. Venting, combustion air, condensate drainage, and electrical access must also be considered.
Propane tankless water heaters can provide similar performance when natural gas is unavailable, provided the propane supply and regulators are properly configured.
Whole-home electric tankless systems are available, but they may require substantial electrical capacity and dedicated circuits. We evaluate the home before recommending electric tankless equipment because an electrical panel upgrade may be necessary.
Navien and Rinnai Tankless Water Heaters
Aaron Services commonly recommends Navien and Rinnai tankless water heaters. Both are established manufacturers with professional-grade equipment, replacement parts, warranty support, and a range of models for different household needs.
The best choice depends on the home rather than the brand name alone. We compare capacity, efficiency, recirculation options, installation requirements, available support, and budget before recommending a particular model.
Professional Installation Matters
Many tankless performance problems can be traced to improper sizing or installation. A gas line that is too small, incorrect venting, improper condensate drainage, restricted water flow, or incorrect system settings can lead to recurring error codes and unreliable operation.
Our plumbers evaluate the installation requirements, account for applicable codes and permits, test the completed system, and explain how to operate and maintain the equipment.
Tankless Water Heater Repair in Lilburn
Tankless water heaters are reliable, but they can still develop problems with age, mineral buildup, heavy use, worn components, or installation defects. An error code may identify the general area of concern, but proper testing is often needed to determine what is actually causing the problem.
Aaron Services provides tankless water heater repair in Lilburn for Navien, Rinnai, and other major brands. We inspect the system, explain our findings, and review repair options before work begins.
Common Tankless Water Heater Problems
Contact a plumber if you notice:
- No hot water
- Water that alternates between hot and cold
- Reduced hot-water flow
- A recurring error code
- Delayed ignition
- Frequent system shutdowns
- Unusual noises during operation
- Water leaking from or around the unit
- Hot water that does not reach certain fixtures
- A unit that regularly needs to be reset
Some problems may be caused by a clogged filter, mineral buildup, or overdue maintenance. Others may involve the igniter, flow sensor, heat exchanger, control board, gas supply, venting, or recirculation system.
Because several issues can produce similar symptoms, replacing a part based only on an error code may not solve the underlying problem. A complete diagnosis should consider the unit’s condition, installation, maintenance history, and current operation.
Why Tankless Water Temperature Fluctuates
Changes in water temperature can result from low or inconsistent flow, scale buildup, dirty filters, incorrect settings, recirculation problems, or failing internal components. The issue may also occur when the household’s hot-water demand exceeds the unit’s capacity.
Our plumbers test the system and look for the source of the temperature change before recommending repairs.
Repair or Replace?
A tankless problem does not automatically mean the unit needs to be replaced. Maintenance, adjustments, or replacement of an individual component may restore normal operation.
Repair may be the practical choice when:
- The unit is otherwise in good condition
- The necessary parts are available
- The repair cost is reasonable
- The system is properly sized and installed
- The problem is isolated rather than recurring
Replacement may make more sense when:
- The system is nearing the end of its expected life
- Major components have failed
- Replacement parts are unavailable
- The unit has required repeated repairs
- The system was improperly sized
- Correcting installation problems would require extensive work
We explain both options when appropriate so you can make an informed decision.
Tankless Water Heater Maintenance in Lilburn
Tankless water heaters require routine maintenance to control mineral buildup and maintain proper operation. Most systems should be inspected and flushed approximately once a year, although water quality, household usage, and manufacturer requirements may call for a different schedule.
Homes with hard water or heavy hot-water use may need more frequent maintenance. Following the manufacturer’s maintenance instructions may also be necessary to maintain warranty coverage.
What Tankless Maintenance Includes
Tankless water heater maintenance may include:
- Flushing the heat exchanger to remove mineral deposits
- Cleaning the water inlet filter
- Inspecting the air intake and exhaust venting
- Checking water, gas, electrical, and condensate connections
- Looking for leaks or corrosion
- Reviewing stored and active error codes
- Testing water flow and temperature
- Inspecting recirculation components when applicable
- Confirming normal system operation
The exact service depends on the unit’s brand, model, age, condition, and installation.
Signs Your Tankless System May Be Overdue for Service
Schedule maintenance if:
- You do not know when the unit was last flushed
- Hot-water flow has become weaker
- Temperatures are less consistent
- The unit has become louder
- Error codes appear more often
- The system takes longer to respond
- Routine maintenance has been delayed for more than a year
You do not need to wait for a performance problem before scheduling service. Removing buildup before it restricts the heat exchanger can help protect the equipment and reduce avoidable repairs.
