R. Davis Mechanical is proudly veteran owned and operated, bringing military precision and commitment to excellence to every tankless water heater installation. Our dedication to quality service and customer satisfaction reflects the values instilled through military service.
Unlike traditional tank water heaters that constantly maintain 40-50 gallons of hot water, tankless systems heat water on-demand as it flows through the unit. When you turn on a hot water faucet, cold water travels through pipes into the tankless unit where powerful burners rapidly heat water to the desired temperature.
This provides endless hot water-you literally cannot run out because the system creates hot water continuously as long as you need it. Never run out during showers, baths, or when multiple fixtures operate simultaneously within system capacity.
Advanced controls maintain precise outlet temperature without the fluctuations common with tank systems. No more temperature drops as the tank depletes or cold water sandwiches during brief usage interruptions.
Tankless units can't catastrophically fail and dump 40-50 gallons of water like aging tank systems. This eliminates the risk of basement flooding from tank failures that can cause thousands in water damage.
Tankless systems typically reduce water heating costs by 24-34% compared to traditional tank water heaters. This comes from eliminating standby heat losses and achieving higher combustion efficiency with advanced condensing technology.
Traditional tank water heaters constantly lose heat through tank walls and piping, requiring frequent reheating even when no hot water is used. Tankless systems have zero standby losses since they heat water only on demand.
Condensing tankless models like Navien NPE-A Series achieve up to 97% efficiency, extracting maximum heat from fuel. This compares to 65-70% efficiency for standard tank water heaters and 80-85% for high-efficiency tank models.
Significant annual energy savings offset higher upfront costs over the system's lifetime. For typical Pittsburgh households, cumulative savings over 20+ years provide substantial value while delivering superior performance.
Quality tankless systems like Navien last 20+ years with proper maintenance versus 8-12 years for tank water heaters. This longevity represents significant value over time, essentially requiring half as many replacements during your homeownership.
With proper annual maintenance, quality tankless systems provide decades of reliable service. This extended lifespan reduces replacement frequency and provides excellent long-term value for homeowners planning to stay in their homes.
Navien offers comprehensive warranties including 15-year heat exchanger coverage on many models, demonstrating confidence in their product quality and longevity. This provides peace of mind for your investment.
Achieving rated lifespan requires annual professional maintenance including descaling to remove mineral deposits. This preventive service protects your investment and ensures optimal performance throughout the system's life.
Wall-mounted tankless units about the size of a suitcase free up valuable floor space that tank water heaters occupy. This space savings is particularly valuable in Pittsburgh homes with limited basement or utility room space.
Tankless units mount securely to walls and occupy minimal space compared to bulky tank water heaters. This frees up floor space for storage, workshop areas, or other uses in your basement or utility room.
Tankless systems can be installed in various locations including basements, utility rooms, garages, or even outdoors with proper protection. This flexibility allows optimal placement for your home's layout and infrastructure.
Wall-mounted installation provides better access for annual maintenance and service compared to tank systems that may be surrounded by stored items or located in tight spaces.
While tankless technology offers significant advantages, homeowners should understand important considerations including higher upfront costs, infrastructure requirements, flow rate limitations, and maintenance needs.
Tankless systems require higher initial investment than tank water heaters, including equipment costs and infrastructure upgrades. However, energy savings and extended lifespan often make tankless better long-term investments.
Most tankless installations require gas line upgrades, new venting systems, electrical service additions, and sometimes water line modifications. These infrastructure improvements add costs but ensure proper operation.
Every tankless unit has maximum flow capacity measured in gallons per minute (GPM). If simultaneous hot water demand exceeds capacity, water temperature drops. Proper sizing prevents this problem.
Professional tankless water heater installation requires far more than simply hanging a unit and connecting pipes. At R. Davis Mechanical, we follow a comprehensive process that ensures your system operates optimally from day one.
We analyze your hot water usage patterns, calculate flow rate requirements, assess infrastructure needs, and recommend the optimal Navien system for your home. This includes evaluating gas supply, venting capabilities, electrical service, and water piping.
Most tankless installations require gas line upgrades from 1/2" to 3/4" or larger, new Category III stainless steel venting, dedicated electrical circuits, and water line modifications. We handle all necessary upgrades to code standards.
Our certified technicians mount the unit securely, connect upgraded gas and water lines, install proper venting, complete electrical connections, and configure all controls. Every connection is tested for safety and performance.
We conduct thorough leak testing, combustion verification, flow testing under maximum demand, safety system verification, and performance documentation. We also provide complete customer education on system operation.

One of tankless water heaters' primary advantages is dramatically reduced energy consumption compared to traditional tank systems. Understanding the economics helps you evaluate whether tankless technology justifies the higher upfront investment.
Traditional tank water heaters constantly lose heat through tank walls and piping, wasting 10-20% of energy consumption. Tankless systems have zero standby losses since they heat water only on demand, providing immediate energy savings.
Condensing tankless models achieve up to 97% efficiency, extracting maximum heat from fuel. This compares to 65-70% efficiency for standard tank water heaters, resulting in significant annual energy cost reductions.
While not strictly an operating cost, tankless systems lasting 20+ years versus 8-12 for tanks means fewer replacement costs amortized over your homeownership, providing excellent long-term value.
While we specialize in tankless installation, R. Davis Mechanical provides honest guidance about which technology truly serves your needs. Sometimes traditional tank water heaters remain the better choice for specific situations.
Large families benefit tremendously from endless hot water. Long-term homeowners see excellent ROI from energy savings and longevity. Space-limited homes appreciate wall-mounted units freeing up floor space.
Tight budgets may favor quality high-efficiency tank systems. Low usage households may not save enough to justify tankless costs. Older homes may require expensive infrastructure upgrades.
We assess your situation honestly, explain realistic pros and cons of each technology, and recommend solutions that genuinely serve your best interests without sales pressure.
Tankless water heaters require annual professional maintenance to achieve their rated 20+ year lifespan and maintain efficiency. Understanding maintenance needs helps you budget appropriately and ensures realistic expectations.
