Tankless Water Heaters in Burien, WA
Experience continuous, endless domestic hot water while freeing up valuable floor space in your utility closet or basement. Washington Plumbing – Burien installs, services, and descales premium high-efficiency condensing tankless water heaters across King County.
Why Burien Homeowners Upgrade to Tankless Water Heating
Traditional storage tanks continuously heat 40 to 80 gallons of water 24 hours a day, suffering standby thermal heat loss. Tankless systems heat water on demand only when a hot water faucet opens.
Never Run Out of Hot Water
Whether running back-to-back morning showers, filling deep whirlpool soaker tubs, or running the dishwasher simultaneously, modern condensing tankless units deliver continuous hot water without running lukewarm.
Unlike storage tanks that require 30 to 60 minutes of recovery time after heavy use, tankless output remains steady indefinitely.
Compact Wall-Mounted Footprint
Eliminate bulky storage cylinders that monopolize valuable square footage in laundry rooms or basements. Modern tankless units mount cleanly on interior or exterior walls.
Their compact size—roughly the dimensions of a carry-on suitcase—frees up space for storage, shelving, or workspace renovations.
20-Year Operational Lifespan
While conventional storage tanks typically fail due to bottom tank corrosion within 8 to 12 years, premium condensing tankless water heaters feature dual stainless steel heat exchangers lasting 20+ years.
Individual components can be serviced and replaced modularly over time rather than discarding the entire unit.
Considering a Tankless Upgrade for Your Burien Home?
Our licensed technicians assess gas supply capacity, electrical requirements, and direct venting pathways for seamless installation.
Gas Supply Line & Direct Venting Requirements
Tankless water heating requires precise engineering to ensure your home's infrastructure supports instantaneous high-BTU gas firing.
High-Capacity Gas Sizing & Electrical
Tankless gas units fire between 150,000 and 199,000 BTUs instantaneously when hot water is called for. In older 1950s Burien homes, existing 1/2-inch gas supply lines feeding 40,000 BTU storage tanks must often be upsized to dedicated 3/4-inch or 1-inch lines.
We calculate total household fuel loads, install heavy-duty gas shutoffs, and verify gas meter regulator capacity to ensure your furnace, range, and tankless heater operate concurrently without fuel starvation.
- Comprehensive gas pressure and pipe capacity load calculations
- Concentric PVC, CPVC, or polypropylene direct sidewall venting
- Built-in recirculation pump options for instantaneous tap hot water
- Dual isolation service valves for easy annual descaling
Annual Descaling & Heat Exchanger Flushing
Although Western Washington municipal water is relatively soft compared to other regions, trace calcium and magnesium minerals gradually bake onto superheated heat exchanger tube walls over time.
We perform routine annual descaling using food-grade virgin citric acid circulated through external service isolation valves to dissolve mineral scale, protect thermal efficiency, and prevent error code shutdowns. We also service conventional storage water heaters.
