Water Heaters: Tank vs Tankless

Which Is Better for Meridian Homes? Tank vs. Tankless Water Heaters?

Is your water heater is nearing the end of its life? Or are you building or remodeling a home in Meridian? If so, you’re probably asking one big question: should I stick with a traditional tank-style water heater or upgrade to a tankless model?

At Plumbing Solutions of Idaho, this is one of the most common questions we hear from homeowners. And for good reason—both types of water heaters have their pros and cons. The right choice depends on your household’s needs, your budget, and your long-term goals.

Let’s break down how each system works, the key differences between them, and what you should consider when choosing a water heater for your Meridian home.

How They Work: Tank vs. Tankless

Tank Water Heaters
Traditional tank water heaters store and heat a set amount of water—typically 40 to 80 gallons. The tank keeps this water hot at all times so it’s ready whenever you turn on a tap.

Key features:

• Constantly maintains hot water temperature
• Usually powered by gas or electricity
• Lower upfront cost
• Lifespan: 8–12 years (on average)

Tankless Water Heaters

Tankless water heaters, also known as on-demand systems, heat water as you need it. When you turn on the hot water, cold water flows through the unit and is instantly heated by gas or electric coils.

Key features:

• No water storage—heats only what you use
• Compact and wall-mounted
• Higher upfront cost
• Lifespan: 15–20 years (with maintenance)

Pros and Cons: Tank vs. Tankless in Real Life

Upfront Cost

• Tank Water Heaters: These are generally more affordable to purchase and install, making them a common choice for homeowners on a budget.
• Tankless Water Heaters: The initial investment is higher, and installation may involve upgrading your plumbing or electrical systems.
• Meridian Takeaway: If you’re replacing a standard tank with another one, it’s a quick and cost-effective switch. But if you’re planning to stay in your home long-term, the investment in tankless may be worth it.

Energy Efficiency

• Tank Models: These use energy to keep water hot around the clock—even when you’re not using it.
• Tankless Models: Since they heat water only when needed, tankless systems tend to be more energy-efficient and can reduce utility bills over time.
• Meridian Takeaway: With Idaho’s rising utility costs and a growing focus on energy conservation, a tankless system could offer meaningful savings for energy-conscious homeowners.

Hot Water Supply

• Tank Models: Limited by tank size. Once the hot water is used up (think back-to-back showers or laundry loads), you’ll need to wait for the tank to refill and reheat.
• Tankless Models: Delivers continuous hot water—as long as the system is properly sized for your home.
• Meridian Takeaway: Larger households may want to stick with a tank or install multiple tankless units to meet high demand. We can help assess your usage to recommend the right setup.
• Space and Location
  Tank Models: Bulky and require floor space—usually installed in a utility closet, garage, or basement.
• Tankless Models: Compact, wall-mounted units that can be installed in smaller areas, including inside cabinets or outside the home (with proper weather protection).
• Meridian Takeaway: If you’re short on space, remodeling, or adding a bathroom, tankless offers flexibility without sacrificing square footage.

Maintenance and Lifespan

• Tank Models: Require flushing to remove sediment buildup and extend lifespan.
• Tankless Models: Require descaling in areas with hard water (like Meridian) but often last longer with proper maintenance.
• Meridian Takeaway: With the hard water in the Treasure Valley, maintenance matters. Fortunately, we offer maintenance plans to keep any system running smoothly, regardless of type.

Which One Is Right for You?

Here are a few quick scenarios to help you decide:

• You’re planning to move in a few years: Stick with a tank system. It’s more affordable and works reliably for the short-term.
• You want lower energy bills over time: Tankless is more efficient and can reduce monthly utility costs.
• You’re building or remodeling: Consider installing a tankless unit—or even multiple—for modern efficiency and flexibility.
• You have a big family: A high-capacity tank may serve you better unless you’re ready to invest in multiple tankless units.
