Tankless water heaters are convenient and energy efficient alternatives to the standard tank-style water heater. Tankless systems can provide you with hot water quickly and won’t take up too much space in your home.

If you are wondering whether you should follow your neighbors and make the switch to tankless water heating, our Washington water heater experts at CPI Plumbing & Heating can help. We will assess your needs and provide you with an honest recommendation on the best type of water heater for your home based on your particular situation and budget.

Tankless Water Heater Benefits

Our Washington plumbing experts can help you set up a new tankless water heater that will allow you to enjoy…

  • Greater space-efficiency: Tankless water heaters can easily fit in small spaces such as utility closets or crawl spaces. If you are looking to maximize the space in your home, then a tankless water heater just might be the solution you need.
  • Longer operational life: While standard water heaters often need to be replaced after 8 to 12 years, tankless systems are expected to last at least 20 years or more with proper maintenance.
  • Hassle-free hot water: No more waiting around for hot water. With a tankless water heater, you can get the hot water you need in just a few seconds. Plus, you won’t have to worry about standby loss since there won’t be any unused hot water sitting idly in a tank—allowing you to enjoy greater energy efficiency over time.

Factors to Consider Before Adding a Tankless Water Heater to Your Washington Home

Compared to standard water heaters, tankless systems may seem like the perfect alternative. However, keep in mind that every home will have different needs. If you decide to move forward with tankless water heater installation, you will likely have to make a few key changes to your electrical and/or gas piping systems.

Tankless water heaters have greater fuel and energy demands compared to standard units, and the typical home isn’t equipped to handle these demands without an upgrade. This means you will need to either upgrade your electrical panel, install larger gas lines or water lines (or both), to accommodate the needs of a tankless water heater.

If you are still interested in adding a tankless water heater to your home and understand the additional work required to set up your new system, your trusted Washington plumbers can help you get started with the installation process.

Frequently Asked Questions about Tankless Water Heater Installation in Mount Vernon, WA

A tankless unit heats water on demand, so it won’t run out the way a storage tank does. However, each unit has a maximum flow rate, measured in gallons per minute. If you run several showers, the dishwasher, and the washing machine at the same time, you may exceed that limit and notice lower water temperatures. Proper sizing is key, especially in Skagit County, where colder incoming groundwater means the unit has to work harder to reach your desired temperature. Our plumbers will help you choose a unit sized for your household’s peak hot water use.
Gas tankless units typically deliver higher flow rates, making them a good fit for larger households that use hot water at multiple fixtures at once. They do require proper venting and an adequate gas supply. Electric units are simpler to install and don’t need venting, but they often require significant electrical capacity and may struggle to keep up with high demand in colder climates. We’ll review your home’s existing gas and electrical setup and help you decide which option makes the most sense.
Most manufacturers recommend flushing and descaling your tankless unit once a year to remove mineral buildup that can reduce efficiency and damage the heat exchanger. Homes with hard water may need more frequent service. Cleaning the inlet filter and checking venting and connections also helps keep your system running smoothly. Pairing your tankless system with a water softener can help reduce scale buildup and extend the life of your unit.
According to the U.S. Department of Energy, tankless water heaters can be 24% to 34% more energy efficient than conventional tank-style units for homes that use 41 gallons or less of hot water per day. Savings vary depending on your household’s hot water usage, the type of unit, and your local utility rates. Our team can help you weigh the upfront cost against your expected long-term savings.
It depends on your home’s layout and hot water needs. A single whole-home unit can supply every fixture in your house and works well for most homes. In larger homes, or where fixtures are far from the water heater, smaller point-of-use units installed near specific bathrooms or the kitchen can deliver hot water faster and reduce wasted water. Our plumbers can recommend the right setup based on your floor plan and daily routine.
