Get a Free Water Heater Estimate and Next-Day Installation
When your water heater fails, everyday tasks like showering, washing clothes, and cleaning dishes become difficult. Logan Services makes replacement easier with a clear process designed to restore your hot water quickly while protecting your home with careful planning, quality workmanship, and complete safety checks.
We offer free, same-day estimates when appointments are available. Once you approve your new system and installation plan, next-day installation may be available on a first-come, first-served basis.
Before work begins, your plumber will explain:
- Which Navien or State system is recommended
- How the system meets your household’s hot water needs
- Whether your home needs plumbing, gas, electrical, venting, or drainage changes
- What work is included with the installation
- Your upfront project price
- When the installation is expected to be completed
What Is Included With Tankless Installation Service?
A tankless water heater must do more than fit on the wall. It needs to provide enough hot water for your household and connect safely to your home’s water, fuel, electrical, venting, and drainage systems.
Your installation may include:
- Inspecting the existing water heater and installation area
- Calculating simultaneous hot water demand and temperature rise
- Confirming whether natural gas or liquid propane is available
- Evaluating the gas service, electrical connection, plumbing, and venting path
- Removing and hauling away the existing water heater
- Mounting the new Navien or State unit
- Installing approved water, gas, electrical, venting, and condensate connections
- Adding required isolation valves, check valves, shutoff valves, and a pressure relief valve
- Testing gas and water connections for leaks
- Verifying combustion, temperature, flow, venting, and safety controls
- Explaining the controls, temperature settings, heater status, and error codes
- Registering the manufacturer’s warranty on your behalf
- Cleaning the work area before we leave
Every home is different, so the exact work depends on the system you choose and the connections already in place. Your Logan Services plumber will explain any required changes, optional accessories, and costs before you approve the installation.
How Logan Services Installs a Tankless Water Heater
1. Evaluate Your Home and Hot Water Needs
Your plumber starts by looking at the existing water heater, available installation space, plumbing, fuel supply, electrical service, and venting options. We also ask how your household uses hot water, including which showers, appliances, and fixtures may run at the same time.
2. Size the System for Ohio Conditions
Choosing the right size involves more than counting bathrooms. Your plumber considers how much hot water your family may use at once and how hard the system must work to heat Ohio’s colder groundwater.
We use those details to recommend a system that can maintain the expected temperature during busy mornings, back-to-back showers, and other periods of high demand.
3. Recommend a Navien or State System
Logan Services installs tankless water heaters from Navien and State. Your plumber will narrow the options based on your home’s fuel source, hot water needs, available space, desired features, and budget.
We explain the differences in plain language so you can choose a system with confidence. You will not be expected to compare technical specifications on your own.
4. Prepare the Installation Area
Replacing a tank water heater with a tankless system may require changes to the gas line, water lines, electrical connection, venting, or condensate drain. We identify those needs during the estimate and safely disconnect the existing equipment before installation begins.
Gas models need approved venting through a sidewall or roof unless the selected unit is designed for outdoor installation. They also commonly require a dedicated 120V outlet for the ignition, controls, and other internal components.
5. Install and Test the New System
Our plumbers protect the work area and complete the approved installation according to manufacturer instructions and applicable local codes. Before turning the system on, we test the gas and water connections for leaks. We then confirm that the unit heats properly, vents safely, and delivers the expected water temperature and flow.
Before leaving, we show you how to adjust the temperature, read the controls, locate the shutoff valves, and recognize when the system may need service. We also clean the work area and answer your questions.
Can Logan Services Replace a Tank Water Heater With a Tankless System?
Many traditional tank water heaters can be replaced with tankless systems. Depending on the home, the conversion may require new venting, a larger gas line, a dedicated outlet, condensate drainage, plumbing changes, or a different installation location.
During your free estimate, a Logan Services plumber checks these requirements before you choose the equipment. You receive a complete plan and upfront price before the project begins.
Navien and State Tankless Water Heater Features
Features vary by model, but you do not need to sort through every specification alone. We explain how each option may affect comfort, maintenance, energy use, and cost in your home.
Energy Efficiency and Heat Exchangers
Select ENERGY STAR® models use condensing technology and durable stainless steel heat exchangers to capture more heat and support long-term performance.
Uniform Energy Factor, or UEF, helps compare water heater efficiency. Your plumber will also explain the venting, drainage, and installation differences between condensing and non-condensing systems because efficiency is only one part of the decision.
Select models also comply with Ultra-Low NOx regulations designed to limit nitrogen oxide emissions.
Recirculation and Controls
Compatible Navien models use ComfortFlow® technology with a built-in recirculation pump, buffer tank, and controls to help reduce the wait for hot water. Select State models also include an integrated recirculation pump.
Depending on the equipment and optional kits, homeowners may be able to:
- Set a pump timer
- Program up to two recirculating schedules
- Manage temperature settings
- Check heater status and error codes
- Activate the heater or recirculation pump remotely
Scale Prevention Protection
Minerals in the water can collect inside the heat exchanger and affect performance. Select State models include X3® Scale Prevention Technology, while other systems can use compatible scale-protection accessories.
X3® technology is designed to protect the heat exchanger from scale buildup and help the unit maintain performance. Your plumber will explain what maintenance and scale protection are appropriate for your system and local water conditions.
Multiple Water Heaters for Larger Applications
One correctly sized unit can meet the needs of many households. Larger homes or high-demand applications may need multiple units connected so they can work together as hot water use increases.
Navien’s Ready-Link® technology allows compatible units to work together in larger applications. Most homes will not need multiple systems, but your plumber can identify when one unit may not provide enough capacity.
Cascade requirements vary by model and quantity. A communication cable may be required; it may be included with certain equipment, while other components are purchased separately.
Does Tankless Installation Require a Permit?
Tankless water heater projects require a plumbing permit and inspection. Gas, electrical, mechanical, or building permits may also be needed when the installation changes fuel lines, wiring, venting, or the structure of the home.
Logan Services identifies the permits required for the approved work and coordinates the inspection process. You will not be left to navigate the requirements alone.
Why Professional Water Heater Installation Matters
Improper installation can lead to gas leaks, unsafe venting, electrical problems, water damage, or incorrect water temperatures. It may also affect the manufacturer’s warranty.
Professional water heater installation helps confirm that:
- The water heater is sized for household demand and Ohio groundwater temperatures
- The gas line can support the unit’s BTU requirements
- Venting and combustion air meet manufacturer and code requirements
- Electrical connections and safety disconnects are completed correctly
- Water and gas connections pass leak testing
- Pressure relief and condensate components are properly installed
- The system is started, tested, and configured correctly
Logan Services plumbers follow applicable codes and manufacturer instructions throughout the project. Safety checks are built into our process from the initial evaluation through final testing.
How Much Does Tankless Installation Cost?
Tankless water heaters usually cost more upfront than traditional tank models. The final price depends on the system you choose and the changes required to install it safely in your home.
Converting from a tank system can cost more than replacing an existing tankless unit because the home may need new venting, gas piping, electrical work, plumbing, or condensate drainage. Your free estimate accounts for the complete project instead of only the price of the equipment.
Logan Services provides the approved project price before work begins. Financing options are available for qualified homeowners who prefer to divide the purchase into monthly payments. Approval and promotional terms are subject to lender requirements.
How Long Does a Tankless Water Heater Last?
A properly installed and maintained tankless water heater can last 20 years or more. Water quality, daily use, maintenance, and installation conditions all affect how long the system lasts.
Because the system does not store a large tank of hot water, it reduces the risk of flooding caused by a ruptured tank. Tankless units and their connections can still leak, so professional installation and routine inspection remain important.
Tankless Water Heater Maintenance
Routine water heater maintenance helps prevent mineral buildup, protect water flow, and keep the system working efficiently. The right service schedule depends on the model, local water quality, household use, and manufacturer requirements.
Water throughout Dayton, Columbus, and Cincinnati contains minerals that can collect inside a water heater over time. Your plumber can explain how local water conditions affect the selected system and whether additional scale protection may help.
Maintenance may include:
- Flushing or descaling the heat exchanger when required
- Cleaning inlet water filters and screens
- Inspecting venting, plumbing, and electrical connections
- Checking combustion and system performance
- Testing safety components
- Reviewing stored error codes
- Maintaining compatible scale-prevention equipment
If the water temperature changes, flow drops, or an error code appears, contact Logan Services. Our plumbers can diagnose the problem without requiring you to open or adjust the unit yourself.
