Gas vs. Electric Systems & GPM Sizing in the Pacific Northwest
Tankless water heaters do not maintain a standby reservoir of heated water. Instead, cold water flows through a high-efficiency copper or stainless steel heat exchanger that instantly warms it upon demand. In Western Washington, incoming groundwater temperatures frequently dip below 45 degrees Fahrenheit during winter months.
To deliver water at a comfortable 120 degrees Fahrenheit, the system must achieve a steep 75-degree temperature rise. This calculation dictates the unit's required Gallons Per Minute (GPM) capacity. A system that works well in a warmer southern state may struggle in a Lakewood home during January if it is not correctly sized for multiple simultaneous fixtures.
Natural gas systems are the most popular configuration for whole-home conversions along Bridgeport Way and near Lakewood Towne Center because they produce high BTU heating outputs (up to 199,000 BTUs) required for simultaneous demands. Electric tankless systems are typically suited for detached workshops, single-fixture additions, or compact apartments where electrical service panels have sufficient amperage capacity.
Sizing Criteria for Lakewood Residences
- Peak Flow Calculation: Adding the GPM flow rate of simultaneous showers (2.0–2.5 GPM), kitchen taps (1.5 GPM), and washing machines (2.0 GPM).
- Winter Groundwater Differential: Accounting for Pacific Northwest cold winter water intake requiring high heat transfer capacity.
- Gas Supply Line Sizing: Verifying that gas supply lines have adequate pipe diameter (often upgrading from 1/2-inch to 3/4-inch or 1-inch lines).
- Concentric PVC/Polypropylene Venting: Installing direct-vent intake and exhaust piping through exterior rim joists.

Annual Descaling Maintenance & Troubleshooting Diagnostic Codes
Tankless water heaters deliver high efficiency and long lifespans, but require regular preventative care to maintain that performance.
Annual Flush & Descaling Service
Because tankless units heat water rapidly across tightly wound heat exchanger coils, dissolved minerals such as calcium carbonate precipitate out of the water and coat internal copper surfaces. Over 12 to 18 months, scale acts as an insulator, reducing heat transfer efficiency and forcing burners to fire hotter.
Our technicians perform a comprehensive system flush using food-grade virgin cleaning solution circulated through isolated service isolation valves. This process dissolves internal lime scale, cleans water inlet filter screens, and restores factory thermal efficiency.
Error Code Diagnostics
Modern units monitor dozens of internal parameters. When issues arise, digital controllers display alphanumeric error codes that indicate specific malfunctions:
- Ignition Failure Codes (e.g., Code 11): Insufficient gas supply, dirty spark electrodes, or blocked intake air.
- Flame Failure Codes (e.g., Code 12): Draft issues, faulty flame sensors, or improper venting condensation drainage.
- Heat Exchanger Overheat Codes (e.g., Code 14): Severe mineral scale obstruction blocking hydraulic water flow.
Upgrading Older Lakewood Properties to Tankless
Many Lakewood homes constructed in the 1950s and 1960s around American Lake, Interlaaken, and Oakbrook have water heaters tucked into narrow hallway closets, cramped laundry alcoves, or low crawlspaces. Replacing a failed 50-gallon tank with another bulky tank takes up valuable usable floor area.
A wall-mounted tankless unit frees up entire utility spaces while eliminating the threat of a 50-gallon tank bursting and soaking your flooring. If you are comparing tankless against traditional units, review our water heater replacement guide for tank pricing and code specifications. For homeowners experiencing sudden failures or leaks, our water heater repair team provides fast diagnostics across all Lakewood neighborhoods listed in our local service areas.
Tankless Benefits Summary
- Wall-mounted footprint saves 12+ square feet of floor space
- Expected service life of 20+ years (double standard tanks)
- Zero standby energy loss keeping water hot when you are away
- Continuous hot water for back-to-back showers and laundry cycles
