Tankless Water Heater Installation Camas WA

Why Tankless Water Heating Excels in Camas

In modern multi-bath homes across Camas—particularly hillside properties along Prune Hill and surrounding Lacamas Lake—large soaking tubs and multi-head walk-in showers frequently overwhelm standard 50-gallon storage water heaters. A tankless water heater eliminates this problem by heating incoming cold groundwater on demand as it passes through a copper or stainless steel heat exchanger.

Rather than burning fuel all day keeping 50 gallons of water hot in an insulated tank, a condensing gas tankless water heater operates only when a faucet opens. This reduces standby energy losses and achieves Uniform Energy Factors (UEF) up to 0.96, saving significant utility costs over the unit's 20-year expected lifespan.

Sizing a Tankless System for Pacific Northwest Groundwater

Selecting the correct tankless unit requires calculating the temperature rise needed between incoming cold water and desired hot water output. In Clark County, winter groundwater temperatures often drop to 45°F. To deliver comfortable 120°F domestic hot water, your system must generate a 75°F temperature rise.

A typical household running two showers and a dishwasher simultaneously requires 7 to 9 gallons per minute (GPM) of hot water. We size premium gas tankless units with input ratings between 180,000 and 199,000 BTUs to ensure full hot water delivery even during the coldest winter mornings.

Maintenance & Descaling Requirements

To protect your manufacturer warranty and maintain high thermal efficiency, tankless heat exchangers require an annual descaling flush. Dissolved minerals and calcium scale build up on interior heat exchanger coils. Without yearly descaling, heat transfer degrades, triggering electronic error codes (such as ignition failure or flame rod errors) and causing premature heat exchanger burnout.

Our technicians connect a circulation pump to isolation service valves, circulating a food-grade virgin vinegar solution through the heat exchanger for 45 to 60 minutes to dissolve mineral scale without damaging metal components.
