Tankless Water Heaters in Seattle: Is It Worth the Upgrade?
As a homeowner in Seattle, you're always looking for ways to make your home more efficient, save on utility bills, and free up space in a market where every square foot counts. That's why the idea of a tankless water heater—also known as an on-demand water heater—is so appealing.
But is it really worth the investment? As the local plumbing pros, we get this question all the time. Let’s break down the pros and cons to help you decide if a tankless water heater in Seattle is the right upgrade for your home.
How a Tankless Water Heater Works
Unlike a traditional tank water heater that keeps a large reservoir of water hot 24/7, a tankless unit heats water only when you need it. When you turn on a hot water faucet, a powerful heat exchanger instantly heats the water as it flows through the unit. This means you get a continuous supply of hot water, on demand.
The Big Advantages for Seattle Homeowners
1. Endless Hot Water
This is the number one reason many people switch. With a traditional tank, once the hot water runs out, you have to wait for the tank to refill and reheat. With a tankless system, you can take multiple back-to-back showers, run the dishwasher, and do a load of laundry without ever running out of hot water.
2. Significant Energy Savings
The biggest energy waste from a traditional water heater is "standby heat loss"—the energy used to keep a tank full of water hot even when no one is using it. Tankless heaters eliminate this waste, as they only use energy when a hot water faucet is on. This can lead to a 24-34% increase in energy efficiency and noticeable savings on your utility bills over time.
3. Space-Saving Design
Tankless water heaters are compact, about the size of a small suitcase, and can be mounted on a wall. For a city like Seattle, where living space is at a premium, this can free up a significant amount of room in your utility closet, garage, or basement.
4. Longer Lifespan
A traditional tank water heater typically lasts 10-15 years before the tank starts to corrode and needs to be replaced. A tankless unit, on the other hand, can last for 20 years or more with proper maintenance, making it a better long-term investment.
The Potential Downsides to Consider
1. Higher Upfront Cost
This is the main drawback for most people. The initial cost of a tankless water heater and its installation is significantly higher than a traditional tank unit.
2. Installation Complexity
A tankless water heater installation is not a simple swap. Gas-powered units, for example, often require a larger gas line and a new venting system to handle the increased demand. Electric units may need significant electrical upgrades. This is why it's critical to hire a professional plumber who is experienced in tankless systems and knowledgeable about Seattle's specific plumbing codes.
3. Flow Rate Limitations
While tankless units provide endless hot water, they have a limited flow rate (measured in gallons per minute, or GPM). If you're running multiple hot water appliances at the same time—like a shower and a dishwasher—a single unit may struggle to keep up, resulting in a drop in water temperature or pressure. For larger families, we sometimes recommend installing a second unit or a high-capacity model to ensure smooth operation.
Is It Worth the Upgrade? Our Professional Verdict
For many Seattle homeowners, the answer is a resounding yes.
If you're a family that constantly runs out of hot water, a household looking to reduce its environmental footprint, or someone who values extra space, a tankless water heater is an excellent long-term investment. While the initial cost is higher, the long-term savings on energy bills and the extended lifespan of the unit often make it a smart financial decision over time.
However, if you're on a tight budget or your home has very low hot water demand, a traditional tank water heater might still be a better fit.
