Transform Your Home’s Hot Water System with Smart Technology

Tankless water heater installation provides Longview, TX homeowners with an energy-efficient solution that ends the frustration of running out of hot water. Unlike traditional tanks that constantly reheat stored water, tankless units heat water on-demand. This delivers endless hot water and can reduce energy consumption by up to 30%.

Quick Installation Overview:

1. Remove old tank water heater: Drain, disconnect, and safely dispose of the existing unit.
2. Upgrade infrastructure: Install larger gas lines or electrical circuits as needed.
3. Mount new unit: Secure the tankless heater to the wall with proper clearances.
4. Connect utilities: Hook up water lines, gas/electric, and venting systems.
5. Test and calibrate: Bleed air, check for leaks, and set temperature controls.

The compact design of a tankless water heater frees up valuable space and can last up to 20 years with proper maintenance—nearly twice as long as traditional models. However, the process involves specialized plumbing, electrical work, and adherence to local building codes, making professional installation the safest choice. For Longview homeowners, this technology is a smart long-term investment that eliminates standby heat loss and ensures reliable, endless hot water.

Is a Tankless Water Heater Right for Your Home?

Switching to a tankless water heater is a smart home improvement for many in Longview, TX. But it’s important to ensure it fits your family’s needs.

Key Advantages Over Traditional Tanks

Imagine never running out of hot water, even when the shower, dishwasher, and laundry are all running. With a tankless system, that’s a reality. These units heat water instantly as it flows, providing an endless supply whenever you need it.

• Energy Efficiency: Traditional tanks waste energy constantly reheating stored water. Tankless systems eliminate this “standby heat loss,” cutting energy consumption by up to 30-40% and lowering your utility bills.
• Space-Saving Design: These compact units mount on a wall, freeing up the floor space once occupied by a bulky tank.
• Durability: A well-maintained tankless unit can last up to 20 years, nearly double the 10-13 year lifespan of a traditional tank.
• Cleaner Water: With no tank, there’s no place for rust and sediment to accumulate, providing fresher water.

Choosing Your Unit: Gas vs. Electric

Both gas and electric models work well, but they have distinct advantages.

Gas units typically heat water faster and support higher flow rates, making them ideal for larger families, though their installation is more involved. Electric models are a great alternative where natural gas isn’t available or for smaller households.

Sizing and Efficiency: Understanding GPM and UEF Ratings

Proper sizing is about flow rate and temperature rise, not tank capacity.

• Flow Rate (GPM): This is the number of gallons per minute (GPM) the unit can heat. To find your peak demand, add the GPM of appliances you might use at once (e.g., shower at 2.5 GPM, kitchen sink at 1.5 GPM). Most Longview homes need a unit that can handle 6-8 GPM.

• Temperature Rise: This is the difference between the incoming cold water temperature and your desired hot water output (e.g., from 50°F to 120°F is a 70-degree rise). A higher temperature rise requires more power, which can affect the maximum flow rate.

• Uniform Energy Factor (UEF): This rating measures overall efficiency. A higher UEF means lower operating costs. Look for ENERGY STAR certified models with a UEF of 0.90 or higher for maximum savings.

Preparing for Your Tankless Water Heater Installation

While we recommend professional installation for safety and reliability, understanding the process helps you appreciate the specialized work involved.

Essential Tools and Materials

A professional tankless water heater installation requires an arsenal of specialized equipment. This includes pipe wrenches, cutters, soldering torches, pressure test gauges for gas lines, and multi-meters for electrical work. The extensive list of tools and materials—from specific pipe fittings and valves to correct venting materials and wiring—underscores why this is a job for experienced technicians, not a typical DIY project.

Critical Infrastructure Upgrades

Many homes require infrastructure upgrades to support a powerful tankless unit. These systems have much higher demands than traditional water heaters.

• Gas Line Sizing: A tankless unit can demand over 100,000 BTU/H, far more than an old tank heater. This often means upgrading your standard 1/2-inch gas line to a 3/4-inch or 1-inch pipe to ensure the unit receives enough fuel to operate effectively. Without this, you’ll experience inconsistent temperatures and poor performance.

• Electrical Requirements: Electric tankless heaters have significant power needs, often requiring multiple dedicated circuits and sometimes a full electrical panel upgrade. Even gas units need a dedicated circuit for their electronic controls. An undersized electrical system is a fire hazard and must be addressed by a certified electrician.

For more on these requirements, see our guide: More info on Water Heater Installation in Tyler, TX.

Understanding Venting and Code Requirements

Gas tankless water heaters need specialized venting that cannot use an existing chimney. Direct-vent systems, which pull combustion air from outside and exhaust gases through dedicated pipes, are the standard for safety and efficiency.

• Venting Materials: The material depends on the unit. Non-condensing units have hotter exhaust and require stainless steel vents. Highly efficient condensing units have cooler, corrosive exhaust and require special PVC or polypropylene venting.

• Local Building Codes: Longview, TX has specific regulations for gas lines, electrical work, venting, and clearances. These are legal requirements for your family’s safety. Attempting a DIY installation without proper permits and knowledge of these codes can lead to dangerous situations, voided warranties, and costly fines. Our team handles all permits and ensures every aspect of the installation is fully compliant.

The Step-by-Step Installation Process (A Professional’s Guide)

While our NATE-certified technicians handle every detail, here is a look at the careful process we follow to install your new tankless water heater safely and efficiently.

Step 1: Safely Removing the Old Water Heater

Removing an old water heater requires precision to prevent water damage or safety hazards.

We begin by shutting off the main water supply, gas line, and electrical circuit breaker. Next, we connect a hose to the drain valve and carefully empty the tank. Once drained, we disconnect the water, gas, and electrical lines. Finally, we remove the bulky old unit and ensure it is disposed of responsibly.

Step 2: Mounting the New Unit and Connecting Water Lines

With the old tank gone, we install your new, compact tankless unit. We select the best location for efficiency and maintenance access, then securely mount it to the wall with heavy-duty brackets, ensuring it is perfectly level. We then connect the cold water inlet and hot water outlet, installing isolation valves that are essential for future maintenance like descaling. For copper piping, we solder each joint to create durable, leak-free connections. You can learn more about our comprehensive services at Water Heater Installation.

Step 3: Finalizing Utility and Vent Connections

This stage requires specialized expertise, particularly for gas units and their venting systems.

• Gas Line: We connect the gas line with a dedicated shut-off valve and a sediment trap to protect the unit’s internal components. Every connection is sealed and tested.
• Electrical: We wire the unit according to manufacturer specifications and local codes, ensuring proper grounding and dedicated circuits for safe operation.
• Venting: For gas units, we install the vent pipes (stainless steel or PVC, depending on the model) with correct slope and weatherproof seals where they exit the home.

Step 4: Testing, Bleeding, and Final Checks

The final step ensures your system operates perfectly from day one. We start by bleeding all air from the pipes by running hot water at fixtures throughout your home. We then conduct a meticulous leak inspection on every water and gas connection. After confirming everything is secure, we fire up the unit following the manufacturer’s startup procedure and calibrate the temperature to your preference. We test multiple faucets to verify consistent temperature and flow before walking you through your new system’s operation.

Post-Installation: Maintenance and Long-Term Care

Your new tankless water heater is a reliable appliance, but a little TLC will ensure it performs at its best for years to come. Proper maintenance is an investment in your comfort and your wallet.

Creating a Maintenance Schedule

Regular maintenance is straightforward and pays off in efficiency and longevity, especially in Longview, TX, where the water can be hard.

• Annual Flushing and Descaling: Minerals in our water (calcium and magnesium) can build up in the heat exchanger, forcing the unit to work harder. During our annual service, we flush the system with a descaling solution to dissolve these deposits and restore peak efficiency.
• Water Filter Cleaning: Most units have a built-in filter to catch sediment. We check and clean this filter during service visits to protect your investment.
• Air Intake Screen Cleaning: For gas units, we clean the air intake screen to ensure proper airflow for efficient combustion.

With proper care, your unit can easily exceed its 20-year lifespan. Learn more in our guide on The Importance of Tankless Water Heater Maintenance.

Signs Your Water Heater Needs Service

Your tankless unit will often signal when it needs attention. Recognizing these signs can prevent bigger issues.

• Inconsistent Temperatures: If your shower water fluctuates between hot and cold, it’s time for a service call.
• Error Codes: The digital display will show error codes when it detects a problem. Don’t ignore these messages.
• Low Water Pressure: A sudden drop in hot water pressure can indicate a clogged filter or mineral buildup.
• Strange Noises: Rumbling or banging sounds are not normal and could indicate internal issues that need professional attention.
• Visible Leaks: Any sign of water where it shouldn’t be requires immediate inspection.
