Is a Tankless Water Heater Right for Your Home?
Tankless water heaters heat water when it is needed rather than storing heated water inside a tank.
They may be suitable for homeowners looking for:
- A compact water-heating system
- An alternative to a traditional storage tank
- A system sized for current hot-water demand
- Replacement of an older tankless unit
- More flexible installation options in qualifying properties
A tankless unit must be selected carefully. Performance depends on the required flow rate, incoming water temperature, number of fixtures used at the same time, and the property’s available gas or electrical capacity.
ENERGY STAR recommends evaluating flow rate, gas supply, electrical service, and venting before choosing a whole-home unit. Review the official ENERGY STAR tankless water heater guidance before purchasing a system.
New Installations and Tank-to-Tankless Conversions
Installing a tankless water heater is not always a direct replacement for a traditional tank-style unit.
A conversion may require changes to:
- Water-line locations
- Gas supply or electrical service
- Venting
- Mounting location
- Shutoff valves
- Condensate drainage
- Existing plumbing connections
Watson Plumbing Company can inspect the current setup and explain which updates may be required before approved installation work begins.
Avoid buying a unit based only on its physical size or advertised output. An undersized system may struggle when several fixtures require hot water at the same time.

Tankless Water Heater Replacement
An existing tankless system may need replacement when it no longer performs reliably, cannot meet current household demand, or is no longer economical to repair.
Replacement may be considered when:
- The unit repeatedly shuts down
- Hot-water temperatures are inconsistent
- Error codes continue to return
- Water leaks from the unit or connections
- Corrosion or physical damage is visible
- Suitable repair parts are unavailable
- The existing system was incorrectly sized
A recurring issue does not automatically mean the entire unit must be replaced. The system should first be evaluated to determine whether repair, maintenance, or replacement is appropriate.
When a replacement is recommended, the new unit should be selected according to current household demand and property conditions rather than assuming the previous model was correctly sized.
What Installation May Include
The exact process depends on the property and chosen system, but qualifying installation may include:
- Inspecting the existing heater and accessible connections
- Determining the required capacity and flow rate
- Removing the old unit when necessary
- Installing and connecting the approved tankless system
- Checking water, fuel, electrical, venting, and drainage connections
- Testing the unit for leaks and proper operation
Additional work may be needed when the system requires a different gas supply, electrical circuit, venting configuration, mounting position, or plumbing arrangement.
Tankless Water Heater Maintenance
Maintenance requirements vary according to the manufacturer, household usage, and local water conditions.
Arrange an inspection if you notice:
- Reduced hot-water flow
- Unstable water temperature
- Repeated error messages
- Unusual operating noises
- Leaks around the unit
- Frequent shutdowns
Mineral buildup may affect some systems over time, particularly in properties with hard-water concerns. Follow the manufacturer’s recommended maintenance schedule rather than relying on a single schedule for every model.
Why Hire a Licensed Plumbing Professional?
Tankless installation may involve water lines, gas piping, electrical service, pressure controls, venting, and drainage. Incorrect sizing or installation can reduce performance and may require expensive corrective work.
Illinois regulates plumbing professionals. Property owners can review the Illinois Department of Public Health plumbing information before approving plumbing work.
A plumber should explain the recommended unit capacity, whether existing connections are suitable, and which property updates may be required.
Frequently Asked Questions About Tankless Water Heater Installation Gillespie IL
Can a tank-style heater be replaced with a tankless unit?
A conversion may be possible, but the property must first be evaluated for hot-water demand, gas or electrical capacity, venting, plumbing connections, and installation space.
How is a tankless water heater sized?
Sizing is based on required flow rate and temperature rise. The assessment should consider how many showers, faucets, and appliances may use hot water simultaneously.
Can you replace an existing tankless water heater?
Qualifying replacement services may be available. The new unit should be compatible with current demand, installation conditions, and available connections.
Does a tankless system provide unlimited hot water?
It can continue heating water while operating within its rated capacity. Performance may decline when simultaneous demand exceeds the unit’s output.
How much does installation cost?
Cost depends on the selected unit, required capacity, existing system, accessibility, venting, fuel or electrical requirements, and necessary plumbing changes.
