When it comes to choosing a water heater for your home, the decision often boils down to two main options: tankless or conventional (tank-style) water heaters. Both have their unique advantages and drawbacks, and the right choice depends on your household’s needs, budget, and long-term goals. At Service Pros Plumbers, we’re here to help you navigate this important decision. In this blog, we’ll break down the differences between tankless and conventional water heaters, so you can make an informed choice for your home.
Whether you’re building a new home, upgrading your current system, or simply exploring your options, understanding the pros and cons of each type of water heater is essential. Let’s dive in!
What Is a Conventional Water Heater?
Conventional water heaters, also known as storage tank water heaters, are the most common type found in homes. They consist of an insulated tank that stores and heats a large volume of water, ready for use whenever you need it.
Advantages of Conventional Water Heaters
- Lower Upfront Cost: Conventional water heaters are generally less expensive to purchase and install compared to tankless models.
- Simplicity: These systems are straightforward and easy to maintain, with widely available replacement parts.
- Reliable Hot Water Supply: As long as the tank is full, you’ll have a steady supply of hot water for multiple uses.
- Ease of Replacement: If you already have a conventional system, replacing it with a similar model is quick and cost-effective.
Disadvantages of Conventional Water Heaters
- Higher Energy Costs: Conventional heaters continuously heat water, even when you’re not using it, leading to higher energy bills.
- Limited Hot Water Supply: Once the tank is empty, you’ll need to wait for the water to heat up again, which can be inconvenient for larger households.
- Space Requirements: These units take up significant space due to the large storage tank.
- Shorter Lifespan: Conventional water heaters typically last 10-15 years, which is shorter than tankless models.
What Is a Tankless Water Heater?
Tankless water heaters, also known as on-demand water heaters, heat water directly as it flows through the unit. Unlike conventional models, they don’t store hot water, providing an endless supply whenever you need it.
Advantages of Tankless Water Heaters
- Energy Efficiency: Tankless heaters only heat water when needed, reducing energy consumption and lowering utility bills.
- Endless Hot Water: You’ll never run out of hot water, making tankless systems ideal for larger households or homes with high hot water demand.
- Space-Saving Design: Tankless units are compact and can be mounted on walls, freeing up valuable floor space.
- Longer Lifespan: Tankless water heaters can last 20 years or more with proper maintenance, outperforming conventional models.
- Reduced Risk of Water Damage: Without a storage tank, there’s no risk of leaks or tank failures that can cause water damage.
Disadvantages of Tankless Water Heaters
- Higher Upfront Cost: Tankless systems are more expensive to purchase and install, especially if retrofitting is required.
- Limited Flow Rate: While tankless heaters provide endless hot water, they can struggle to supply multiple fixtures simultaneously if the unit is undersized.
- Complex Installation: Retrofitting a tankless system may require upgrades to your home’s gas lines or electrical system.
- Maintenance Requirements: Tankless systems need regular descaling to prevent mineral buildup, especially in areas with hard water.
Tankless vs. Conventional: Key Factors to Consider
When deciding between a tankless and conventional water heater, consider the following factors:
- Household Size and Hot Water Demand: Larger households with high hot water usage may benefit from the endless supply of a tankless system. Smaller households may find a conventional heater sufficient.
- Energy Efficiency: If reducing energy costs is a priority, a tankless water heater is the more efficient choice.
- Upfront Budget: Conventional water heaters are more affordable upfront, while tankless systems offer long-term savings.
- Space Availability: If space is limited, a tankless unit’s compact design may be a better fit.
- Long-Term Goals: If you plan to stay in your home for many years, a tankless system’s longevity and energy savings may justify the higher initial cost.

Tankless units are significantly smaller than conventional tanks, often about the size of a small suitcase. They can be mounted on walls, freeing up floor space.

Yes, but the switch may require upgrades to your home’s gas lines, electrical system, or ventilation. A professional plumber can assess your home’s compatibility.

Which Water Heater Is Right for You?
The choice between a tankless and conventional water heater ultimately depends on your household’s needs, budget, and long-term goals. Tankless systems offer energy efficiency, endless hot water, and space-saving benefits, making them ideal for larger households or those looking to reduce their environmental impact. Conventional water heaters, on the other hand, are more affordable upfront and simpler to install, making them a practical choice for smaller homes or those on a tight budget.
