High-Efficiency Tankless Water Heaters in Kennewick, WA
How Tankless Water Heating Works
Unlike conventional storage tank water heaters that continuously burn gas or consume electricity to keep 40 to 80 gallons of water hot 24 hours a day, a tankless water heater operates strictly on demand. When a hot water tap, washing machine, or shower is turned on, cold water flows through a high-precision flow sensor into a primary copper or stainless steel heat exchanger.
High-output modulating gas burners or advanced electric heating grids ignite instantly, warming the water to your exact setpoint temperature as it passes through. As soon as the faucet closes, the unit shuts off completely, eliminating standby heat losses and lowering monthly utility consumption significantly.

Endless Hot Water on Demand
Run morning showers, laundry cycles, and the dishwasher simultaneously without running out of hot water. As long as water flows, the unit delivers consistent hot water.
Compact, Space-Saving Footprint
Tankless heaters mount cleanly onto interior utility walls or garage framing, freeing up the 10 to 15 square feet of floor space previously occupied by a bulky storage cylinder.
Extended Operational Lifespan
Because tankless units do not store standing water, they do not suffer catastrophic tank wall rusting. With annual descaling, quality tankless systems last 20+ years compared to 10 years for tanks.
Substantial Energy Savings
Operating at up to 96% thermal efficiency (compared to 60–65% for standard atmospheric tanks), tankless systems drastically reduce natural gas usage in Benton County homes.
Critical Technical Considerations: Kennewick Conversions
Switching from a traditional storage tank to a high-capacity tankless water heater requires technical expertise. Our plumbers engineer every installation to account for the specific requirements of the property:
- Adequate Gas Supply Volume: While a standard tank heater burns roughly 40,000 BTUs per hour, an on-demand tankless system requires between 160,000 and 199,000 BTUs to heat water instantaneously. We calculate existing gas line sizing from your meter, up-sizing pipe runs where necessary to prevent gas starvation to your furnace.
- Dedicated Direct Venting: Modern condensing tankless units extract so much heat from combustion gases that exhaust temperatures remain low enough to vent through dedicated PVC or polypropylene pipes routed through exterior sidewalls, bypassing older masonry chimneys.
- Electrical Dedicated Circuit: Electronic controls, digital igniters, internal freeze protection heat blankets, and modulating fan motors require a reliable 120V outlet near the installation location.
- Condensate Drain Management: High-efficiency condensing units produce slightly acidic moisture as a byproduct of combustion. We install acid-neutralizing filters and dedicated drain lines to protect your foundation and local plumbing lines.
Combating Tri-Cities Hard Water: Annual Descaling Maintenance
Kennewick's municipal water supply contains elevated concentrations of dissolved calcium and carbonate minerals. Inside a tankless heater, water passes through tightly finned micro-channels within the heat exchanger. Over time, high surface heat causes calcium to precipitate, creating scale deposits that restrict flow and insulate the exchanger, triggering error codes or temperature fluctuations.
Washington Plumbing installs isolation service valves standard on all new tankless units. This allows our technicians to connect recirculation flush pumps and circulate non-toxic food-grade descaling solution through the heat exchanger annually. Regular descaling dissolves stubborn scale, preserves manufacturer warranty coverage, and maintains peak thermal efficiency.
Frequently Asked Questions About Tankless Systems
Can a tankless water heater freeze during severe Kennewick winters?
Quality outdoor-vented and garage-mounted tankless units feature built-in ceramic heating elements that activate automatically when ambient temperatures approach freezing. However, during power outages, exterior vent pipes can draw cold drafts into the unit. We install spring-loaded backdraft dampers and explain simple manual drain procedures to safeguard your system during extended winter power loss.
How often should a tankless water heater be flushed in Kennewick?
Due to Benton County's moderate-to-hard water conditions, we recommend annual descaling flushes. If your home has a whole-house water softener installed, this maintenance interval can often be safely extended to every 18 to 24 months.
Is an on-demand unit capable of providing hot water instantly at the faucet?
A tankless heater begins producing hot water instantly, but water in the intervening supply pipes between the heater and your fixture must be cleared first. For large floor plans in Kennewick, we install models with internal or external recirculation pumps to deliver rapid hot water to distant bathrooms.
