Tankless Water Heater Installation in Kitsap County, WA: Costs, Brands & What to Expect
Thinking about upgrading to a tankless water heater in Kitsap County? You’re not alone. Homeowners throughout Bremerton, Poulsbo, Silverdale, and Port Orchard are making the switch—and for good reason. Tankless units deliver endless hot water on demand, last 5–10 years longer than traditional tank heaters, and can reduce water heating energy costs by 20–35%. At Pelican Plumbing, we install tankless water heaters throughout Kitsap County and the surrounding area. Here’s everything you need to know before you commit.
What Is a Tankless Water Heater?
A tankless water heater (also called an on-demand or instantaneous water heater) heats water directly as it flows through the unit—rather than storing a tank of pre-heated water. When you turn on a hot water tap, cold water travels through a pipe into the unit, where a gas burner or electric element heats it instantly. You get continuous hot water without the standby energy loss of a traditional tank.
The two main types are:
- Gas tankless water heaters: Powered by natural gas or propane. Higher flow rates (5–10 GPM), better suited for whole-home use. Most popular for Kitsap homes with gas service.
- Electric tankless water heaters: No gas line required. Easier to install but typically lower flow rates and higher operating costs in Washington State’s electricity environment unless you have solar.

Top Tankless Water Heater Brands We Install
Rinnai
Rinnai is the most-installed tankless brand in North America. Their gas units are known for durability, high efficiency (up to 96% AFUE for condensing models), and reliable performance in cold-water-inlet conditions like Kitsap County. The RU and RUR series are popular whole-home choices. Rinnai units come with a 12-year heat exchanger warranty and a 5-year parts warranty.
Navien
Navien NPE condensing tankless heaters are built in South Korea and have gained a strong following in the Pacific Northwest. They’re known for stable water pressure and temperature at multiple simultaneous fixtures. The NPE-A2 series offers up to 0.96 EF and is EnergyStar certified. Navien offers a 15-year heat exchanger warranty.
Noritz
Noritz is a solid mid-range choice with excellent parts availability in the Pacific Northwest. Their NRC and EZTR series offer strong efficiency ratings and straightforward installation. Noritz is popular for budget-conscious installs that still need solid reliability.
Bradford White
Less common in the tankless space but a trusted brand for tank water heaters. Their tankless line is worth considering for homeowners already familiar with the brand through previous installs.
Gas Tankless vs. Traditional Tank: Is It Worth It in Kitsap?
The honest answer: for most Kitsap County homeowners, gas tankless is the right long-term investment. Here’s why:
- Lifespan: Tankless units typically last 20+ years vs. 8–12 years for tank heaters.
- Energy savings: Tankless eliminates standby loss. Washington Gas customers typically save $80–$200/year on water heating bills.
- Space savings: A tankless unit is about the size of a carry-on suitcase. A 50-gallon tank takes up significant floor space.
- Unlimited hot water: Never run out mid-shower when the family is home. A properly sized tankless unit handles simultaneous demand.
- Higher upfront cost: The main drawback is cost. Tankless installs cost $500–$1,500 more than a tank replacement. But the longer lifespan and energy savings typically offset this within 5–8 years.
What the Installation Process Looks Like
1. Assessment & Sizing
We start by calculating your peak hot water demand (gallons per minute) based on your household size and fixture count. For most Kitsap single-family homes, a 7–9 GPM gas unit handles whole-home demand. We also assess your gas line size, venting configuration, and whether any upgrades are needed.
2. Permits
Tankless water heater installations in Kitsap County typically require a plumbing permit. We handle permitting with Kitsap County’s Department of Community Development or the relevant city building department (Bremerton, Poulsbo, Port Orchard, etc.).
3. Removal of Existing Unit
We disconnect and remove your existing water heater and dispose of it properly. If you have a tank unit that’s still functional but you’re upgrading, ask about options for donating or repurposing.
4. Gas Line & Venting
Gas tankless units require ¾” or 1″ gas lines (larger than most tank units use) and Category III or IV stainless steel venting. If your current gas line is undersized or venting needs to be rerouted, this is the primary source of additional installation cost. We’ll identify these requirements during the assessment.
5. Unit Installation & Commissioning
We mount the unit, make all gas, water, and venting connections, and flush the system. Commissioning includes setting the temperature (typically 120°F), testing all outlets for flow rate and temperature consistency, and checking for error codes.
6. Permit Inspection & Documentation
We schedule the county or city inspection, provide you with the manufacturer warranty documentation, and walk you through basic maintenance (annual descaling in Kitsap’s moderately hard water environment).
Maintenance Tips for Kitsap County Homeowners
Kitsap County’s water hardness averages 60–120 mg/L (moderately hard), which can cause mineral buildup in tankless heat exchangers over time. We recommend:
- Annual descaling/flushing with a food-grade descaling solution to prevent calcium buildup in the heat exchanger.
- Inlet filter cleaning every 6–12 months to maintain flow rate.
- Annual professional service check to inspect the burner, igniter, and venting for safe operation.
Most manufacturers void warranties if annual maintenance isn’t performed. Pelican Plumbing offers service contracts for ongoing maintenance.
Frequently Asked Questions
Can a tankless water heater handle a large Kitsap County home?
Yes, with proper sizing. A 199,000 BTU gas condensing unit (like the Rinnai RUR199iN or Navien NPE-240A2) delivers 9–11 GPM—enough for 3–5 simultaneous hot water uses. For very large homes (5+ bedrooms) or high-demand commercial applications, we can install two units in a parallel configuration.
Do I need to upgrade my gas line for a tankless water heater?
Many homes in Kitsap County were built with ½” gas lines serving tank water heaters. High-BTU tankless units typically require ¾” or 1″ gas supply lines. If your existing line is undersized, we’ll need to run new gas line from the meter or a nearby manifold. This is common and adds $200–$600 to the project depending on distance and accessibility.
How long does tankless installation take?
A straightforward swap from tank to tankless (assuming no gas line or venting upgrades are needed) typically takes 4–6 hours. If gas line or venting work is required, expect a full day or potentially two visits.
Are there rebates available for tankless water heaters in Washington?
Yes. Puget Sound Energy (PSE) and Cascade Natural Gas (now Avista) have offered rebates of $100–$300 for installing Energy Star-certified gas tankless water heaters. Washington State also offers sales tax exemptions on certain energy-efficient appliances. Rebate programs change frequently—ask us about current availability when you request your estimate.
What happens if the power goes out?
Gas tankless water heaters require electricity for the igniter and controls. During a power outage, most gas tankless units will not operate. Some models have battery backup functionality. If power outages are a concern in your area, ask us about units with that feature or consider a whole-home generator.
