Frequently Asked Questions About Tankless Water Heater Installation in Washington
Have questions about tankless water heater installation in Washington, UT? Iron Mountain Plumbing, Heating, and Air is here to help. We understand that upgrading to tankless can feel like a big step, which is why our licensed plumbers provide clear guidance, expert installation, and dependable service every time.
To make things easier, we’ve gathered answers to some of the most common questions homeowners ask about tankless water heaters. From choosing the right system to understanding costs and maintenance, Iron Mountain Plumbing is here to ensure you feel confident about your investment.
Traditional water heaters use a large storage tank to hold and heat water for your home. The tank size determines how much hot water is available at once, and installation requires enough space to house the unit. These systems heat water continuously, which can lead to higher energy use.
Tankless water heaters eliminate the storage tank by heating water on demand as it flows through the unit. This design provides endless hot water, saves space, and improves energy efficiency. While installation can involve additional plumbing or electrical upgrades, many homeowners choose tankless systems for their longer lifespan, compact size, and long-term savings.
Tankless water heaters provide several advantages over traditional tank models, making them a smart investment for many Washington homeowners:
- Hot Water on Demand: Tankless systems deliver hot water instantly whenever you turn on the faucet, without waiting for a tank to refill and reheat.
- Space-Saving Design: These units are compact and can be wall-mounted, freeing up valuable space in your home.
- Energy Efficiency: By heating water only when needed, tankless systems can reduce energy use and help lower utility bills by up to 35%.
- Longer Lifespan: With proper maintenance, tankless water heaters can last 15–20 years, nearly double the lifespan of many standard tank units.
- Consistent Performance: Properly sized tankless units provide reliable hot water, even when multiple fixtures are in use.
For homeowners who want efficiency, convenience, and long-term savings, a tankless water heater is an excellent choice.
With proper installation and maintenance, most tankless water heaters last 15 to 20 years, which is significantly longer than the 8 to 12 years of a standard tank system.
The cost depends on the size of the unit, fuel type (gas or electric), and any plumbing or electrical upgrades needed. While installation may be more expensive upfront than a tank system, tankless units typically save money over time through energy efficiency.
Yes, many homeowners upgrade from tank to tankless. Our licensed plumbers will evaluate your home’s plumbing, gas lines, and electrical setup to make sure your system is ready for a tankless installation.
Yes. Annual maintenance, including flushing the unit to remove mineral buildup, helps keep your tankless system running efficiently and extends its lifespan.
Yes, when properly sized. Our team will help you choose the right unit for your home’s hot water needs, whether you’re supporting a single bathroom or multiple showers and appliances running at once.
