Tankless Hot Water Heater Installation & Repair in Kent, WA

When it comes to upgrading your home’s water heating system, a tankless water heater is one of the smartest investments you can make. At Pike Plumbing & Sewer, we’ve spent several years helping homeowners and businesses throughout the Puget Sound region make the switch to efficient, space-saving tankless systems. With over 4,000 completed projects and consistently high ratings from our customers, we know exactly what it takes to install and maintain these systems properly.

Why Choose a Tankless Water Heater?

Tankless water heaters work differently than traditional tank systems. Instead of storing heated water in a large tank, they heat water on-demand as it flows through the unit. This means several important benefits for your home:

Energy Efficiency: Tankless systems use 24-34% less energy than traditional tank heaters, according to the U.S. Department of Energy. That translates directly to lower utility bills month after month.

Space Savings: These compact units mount on your wall and take up a fraction of the space a traditional tank requires. If you’re short on space in your basement or utility room, a tankless system is ideal.

Endless Hot Water: You’ll never run out of hot water again. Whether you’re filling a bath, doing laundry, or showering while someone else washes dishes, tankless systems keep up with demand.

Longevity: With proper maintenance, tankless water heaters last 15-20 years—about 5 years longer than traditional tanks.

Lower Maintenance: These systems require less frequent maintenance and have fewer parts that can fail compared to tank models.

Our Tankless Water Heater Installation Process

We don’t just show up and install your system. Our process is thorough, professional, and designed to ensure your new tankless water heater performs perfectly from day one.

Step 1: Professional Assessment

We evaluate your current plumbing setup, water pressure, and hot water demands. This helps us recommend the right size and type of tankless system for your specific needs. An undersized unit will struggle to keep up; an oversized one wastes money.

Step 2: System Selection

We help you choose between gas and electric tankless heaters based on your home’s infrastructure and your budget. Gas units typically have higher flow rates, while electric models are often easier to install.

Step 3: Professional Installation

Our licensed plumbers handle all aspects of installation, including venting (for gas models), water line connections, and electrical work. We ensure everything meets local codes and manufacturer specifications.

Step 4: System Testing

Before we leave, we thoroughly test your new system to confirm proper operation, water temperature consistency, and safety features.

Step 5: Maintenance Guidance

We provide clear instructions on maintaining your system and schedule regular check-ups to keep it running efficiently.

Common Issues We Fix

Mineral Buildup: In areas with hard water, minerals accumulate inside your tankless unit, reducing efficiency. We perform descaling to remove buildup and restore performance.

Temperature Fluctuations: If your water temperature bounces between hot and cold, it might be a flow sensor issue or improper installation. We identify and fix the root cause.

Low Water Pressure: Sometimes the problem isn’t the heater itself—it’s your water lines or a faulty pressure valve. We investigate thoroughly.

Ignition Issues: Gas tankless heaters rely on precise ignition systems. We repair or replace ignition components as needed.

Venting Problems: Improper venting reduces efficiency and can create safety concerns. We inspect and correct venting issues.

Many of these issues can be prevented with proper maintenance. That’s why we recommend annual maintenance, such as descaling service and inspection. 

We offer thermal expansion tank repair services as well.

Maintenance Tips for Longevity

To maximize your tankless water heater’s lifespan and efficiency:

  • Annual Flushing: Schedule yearly descaling to remove mineral deposits, especially if you have hard water.
  • Check Water Filters: Replace inlet filters regularly to prevent debris from damaging internal components.
  • Inspect Venting: For gas models, ensure venting isn’t blocked or damaged.
  • Monitor Performance: Pay attention to changes in water temperature or pressure—these often signal maintenance needs.
  • Professional Inspection: Have our team inspect your system annually to catch potential issues early.

We’re here to help with all your water heater services. Whether you need installation, repair, or maintenance, Pike Plumbing & Sewer has the expertise and experience to deliver results you can trust.

Frequently Asked Questions

How much does tankless water heater installation cost?

Installation costs vary based on your home’s current setup, the type of unit you choose (gas or electric), and any necessary upgrades to venting or water lines. Gas tankless heaters typically cost more  to install, while electric models can be a cheaper option.. 

We provide free estimates so you know the exact cost before we begin work. The energy savings usually pay back the investment within 5-7 years.

How long does tankless water heater installation take?

Most installations take 4-8 hours, depending on your home’s plumbing configuration and whether we need to upgrade water lines or venting. We’ll give you a specific timeframe during your consultation. We work efficiently to minimize disruption to your home while ensuring every connection meets code requirements.

What size tankless water heater do I need?

The right size depends on your household’s peak hot water demand—how many showers, appliances, and fixtures run simultaneously. We calculate this during our assessment and recommend a unit with the appropriate flow rate (measured in gallons per minute). Undersizing causes cold water to mix in, while oversizing wastes money. Our experts get this right so you have consistent hot water without overpaying.

Incredible service. We have had a sewer vent pipe issue causing an awful smell in our house. Another plumbing company didn't properly diagnose this issue. I called Pike, and wow, they got a plumber out the same day who assured me it was fixable and had the smell gone withing 2 hours. He identified the defective fitting that was allowing sewer gas to escape and showed me how it was defective. He then changed the type of connection to one that was more appropriate. Honest, fair price, efficient work, professional communication. I highly recommend !

Prompt, courteous, professional, and quick work. I have been struggling with vendors through Americans home shield for months with no result. These folks came out and fixed it after one phone call less than 24 hours for a reasonable fee. Kudos highly recommended.

Pike crew did an excellent job, part of the problem I had was caused by a mistake I made replacing a fill valve that cross threaded a connecting tube. Pike Plumbing team spotted this immediately and fixed it as well as a loose connection. Excellent job by real professionals! Going forward I will use Pike Plumbing for all our plumbing needs and am very pleased to leave a 5 star Google review.

Anthony from Pike Plumbing did a great job. He explained what he was doing as he went through things.

Dan Wirkkala

Had to replace my water heater and found that Pike Plumbing was the first to respond and showed up on time with knowledgeable and honest professional plumbers. They took a look at my water heater, provided me my options to fit my budget and ended up Replacing my twelve year old tank with a new one at a competitive price. The summary of this story was they were first to respond, showed on time, they were professional and replaced my unit with a competitive price and did not take advantage of my immediate need to replace the unit. I would highly recommend Cody and his apprentice out of Granite Falls, WA for any of your plumbing needs. Sincere thanks!
