Introduction

Choosing your home’s water heater in Cooper City, FL is one of the most important decisions you’ll make as a homeowner. Whether you’re building a new home, upgrading an old unit, or trying to improve energy efficiency, you’ve likely come across the two main types: tankless and tank-style water heaters.

At Dovis Plumbing, we get this question all the time. Which one should I buy? Let’s break down the key differences to help you make the best choice for your home, budget, and lifestyle in Cooper City, FL.

What’s the Difference?

• Tank water heaters (also called storage water heaters) store hot water in a large tank, typically 40 to 80 gallons, keeping it hot around the clock.
• Tankless water heaters (also known as on-demand heaters) don’t store water at all. Instead, they heat it instantly as it flows through the unit when you turn on the tap.

Performance: Which One Delivers?

• Tankless: These units deliver a steady supply of hot water, typically at 2–5 gallons per minute. They’re great for smaller homes or households with moderate water use. However, running multiple showers and appliances simultaneously may exceed their flow rate.
• Tank: Tank water heaters are built for volume. A 50-gallon tank can deliver up to 80 gallons of hot water in the first hour, great for large families or homes with high water demands.

Best for High Volume: Tank Water Heater

Efficiency and Energy Use

• Tankless: The clear winner in energy efficiency. These units only heat water when it’s needed, which can reduce energy use by up to 34% in homes with lower daily water usage (under 41 gallons).
• Tank: These heaters constantly maintain hot water, even when you’re not using it, using more energy. Adding insulation helps, but it’s still less efficient than tankless.

Best for Energy Savings: Tankless Water Heater

Maintenance

• Tankless: Requires occasional flushing and descaling to remove mineral buildup, especially in areas with hard water. You’ll also need to clean filters and inspect the system annually.
• Tank: Needs to be flushed once a year to remove sediment. It’s also important to check the temperature and pressure relief (T&P) valve regularly.

Best for Low Maintenance: Tie. Both systems need basic upkeep to stay efficient.

Lifespan

• Tankless: With proper care, a tankless water heater can last up to 20 years.
• Tank: Standard tank water heaters have a shorter lifespan, typically 8 to 12 years.

Best Long-Term Investment: Tankless Water Heater

Installation

• Tankless: Installation is more complex and may require new gas or electrical lines. Professional installation is essential, and it’s not a simple switch-out from a tank system.
• Tank: Easier and faster to install, especially if you’re replacing an old tank system. Most plumbers (including us at Dovis!) can handle this quickly.

Easiest to Install: Tank Water Heater

Cost

• Tankless: Expect to pay $1,200 to $4,250 depending on the model and installation needs. While pricey upfront, energy savings can offset the cost over time.
• Tank: More budget-friendly, with installation costs ranging from $975 to $2,400.

 Best for Budget: Tank Water Heater

Appearance & Space

• Tankless: Compact and wall-mounted, perfect for smaller homes or tight spaces.
• Tank: Bulky, with clearance requirements. Can take up significant floor space in garages or utility rooms.

Best for Saving Space: Tankless Water Heater

So, which one should you choose?

At Dovis Plumbing, we recommend

• Tankless water heaters are for smaller homes, eco-conscious families, or those looking for long-term energy savings and compact design.
