Why Homeowners Choose Tankless Water Heaters
Tankless water heaters offer major advantages, but they are not the right fit for every home. Before recommending a new system, we evaluate the factors that matter most.
Endless Hot Water
Tankless systems heat water on demand instead of storing it in a tank. This means you do not have to worry about running out of hot water in the middle of a shower or while multiple fixtures are running.
Improved Energy Efficiency
Because a tankless unit only heats water when needed, it avoids the standby heat loss that happens with standard tank systems. This can reduce monthly energy costs over time.
Longer Lifespan
A traditional tank water heater often lasts 8 to 12 years. A properly maintained tankless unit can often last 15 to 20 years or more.
Space-Saving Design
Tankless systems are mounted on the wall and take up much less space than a standard storage tank water heater.
Lower Long-Term Ownership Costs
While the upfront investment is higher, many homeowners benefit from lower energy bills, longer system life, and reduced risk of tank failure and flooding.
Is Tankless Right for Your Home?
Tankless water heaters are a strong option for many homeowners in Plano, Collin County, and North Dallas, but not every home is an ideal match. We evaluate several important factors before recommending a conversion.
Household Size and Hot Water Demand
Tankless works especially well in homes with high daily hot water use or where hot water demand is spread throughout the day. If your household often runs out of hot water with a traditional tank, tankless may be a great solution.
Existing Fuel Source
If your current water heater already uses gas, switching to a gas tankless unit is often simpler. If your home does not have gas service, we can evaluate whether adding a gas line or installing an electric tankless unit makes more sense.
North Texas Hard Water
Hard water is a major factor in this area. Collin County and North Dallas water commonly measures 15 to 20+ grains per gallon, which can cause mineral scale to build up inside the heat exchanger. We help homeowners understand the maintenance requirements before installation.
Budget and Long-Term Goals
Tankless systems cost more upfront, but many homeowners recover that investment over time through longer lifespan and improved energy efficiency. During your consultation, we provide a realistic cost comparison based on your specific situation.
When Tankless May Not Be the Best Choice
We do not recommend tankless to every homeowner. There are situations where a standard tank water heater may be the better option.
A traditional system may make more sense if keeping the upfront cost as low as possible is your top priority. It may also be the better fit if your home would require major gas line work, electrical panel upgrades, or complex venting changes that significantly increase installation cost.
For homes with very low hot water usage, the long-term energy savings may not justify the higher initial investment. If you plan to sell your home soon, a new standard tank water heater may be the more practical solution. Our goal is to recommend the option that actually makes sense for your home, not simply push an upgrade.
Gas vs Electric Tankless Water Heaters
We install both gas and electric tankless water heaters. The right choice depends on your home’s infrastructure, your household demand, and your long-term goals.
Gas Tankless Water Heaters
Gas tankless units are the most common whole-house option in North Texas. They generally provide higher flow rates and handle multiple fixtures at once more effectively. They are ideal for homes with existing gas service or homes that can support a gas line upgrade.
Best for:
- Whole-house hot water demand
- Multiple simultaneous fixtures
- Homes with existing gas service
Brands we install:
Rinnai, Navien, Noritz, Rheem, Takagi, Bosch
Electric Tankless Water Heaters
Electric tankless systems can work well for smaller homes, point-of-use applications, or properties without gas service. However, whole-house electric tankless systems often require major electrical capacity, especially in North Texas where incoming water temperature can require a larger temperature rise.
Best for:
- Smaller homes
- Point-of-use applications
- Homes without gas service
Brands we install:
EcoSmart, Stiebel Eltron, Bosch, Rheem, Trutankless
Because North Texas incoming water temperatures commonly range from 55 to 65 degrees depending on the season, electric units may deliver lower flow rates than many homeowners expect. We measure actual conditions during the consultation so you understand what the unit can realistically provide.
What a Tank-to-Tankless Conversion Involves
Converting from a standard tank system to tankless is not just a simple swap. Most homes require additional work to ensure safe and proper installation.
Old Water Heater Removal
We fully drain, disconnect, remove, and dispose of the existing tank water heater. This includes careful handling in garages, utility rooms, attics, or tighter installation spaces.
Gas Line Assessment and Upgrade
Many traditional tank water heaters use a ½-inch gas line, while tankless gas systems typically require a ¾-inch or 1-inch line due to the higher BTU demand. We assess your current gas supply and determine whether upgrades are required.
Venting Modifications
Existing venting from a standard gas tank heater usually cannot be reused for tankless. Depending on the model, the new system may require Category III stainless venting or PVC venting for condensing units. We evaluate the best route and install it to code.
Electrical Assessment
Electric tankless systems often require multiple dedicated breakers and significant panel capacity. We assess your existing electrical system before recommending an electric unit.
Water Connections and Service Valves
We install the required plumbing connections, isolation valves, and service ports for future maintenance and descaling.
Testing and Calibration
After installation, we test flow rate, outlet temperature, system function, and safe operation. Gas units also receive combustion analysis to verify safe exhaust performance.
Factors That Affect Tankless Installation Cost
Tankless installation cost depends on the home and the scope of the project. During your estimate, we evaluate every factor that affects pricing.
These include whether the installation is a brand-new system or a conversion from a tank, whether you are choosing gas or electric, whether gas line modifications are needed, whether electrical upgrades are required, and how complex the venting route will be. We also discuss optional upgrades such as water softeners and recirculation systems. Our estimates are written, detailed, and transparent. You will see all costs before work begins.
Tankless Brands We Install and Service
We are not tied to a single brand. We install and service all major tankless manufacturers and recommend the unit that fits your home and goals.
Brands include:
- Rinnai
- Navien
- Noritz
- EcoSmart
- Rheem
- Takagi
- Bosch
- Stiebel Eltron
- Trutankless
- Eccotemp
If you already have a preferred brand or want to match an existing system, we can help you source and install the right unit.
What to Expect During Tankless Installation
1. Home Evaluation
We assess your gas or electrical capacity, measure incoming water temperature, review venting options, and evaluate your household’s hot water use.
2. Written Recommendation
You receive a clear recommendation with a specific model, installation scope, and full written estimate.
3. Pre-Installation Work
If gas line, venting, or electrical upgrades are needed, we coordinate those steps so installation goes smoothly.
4. Installation Day
Most tankless installations take about 4 to 8 hours and are completed in one visit. We remove the old unit, mount the new system, complete the water, gas, electrical, and venting connections, and install all required components.
5. Testing and Walkthrough
We test the system thoroughly, verify hot water performance, and walk you through how the new system works, including maintenance expectations and system controls.
Maintenance Matters in North Texas
Tankless systems are efficient and durable, but only when properly maintained. Hard water in Collin County and North Dallas causes scale buildup in the heat exchanger, which can reduce flow rate, trigger error codes, and shorten the life of the system.
That is why annual descaling is strongly recommended. Homes without a water softener may require service every 6 to 12 months. We explain these maintenance needs clearly during the consultation so you know exactly what to expect.
