If you need to replace your water heater, you have a few options. You can purchase either a traditional tank water heater or a newer tankless unit.
While tankless water heaters offer significant benefits for many households, you need to consider your hot water needs, budget, and long-term goals before investing.
Understanding the pros and cons of each type of water heater, along with their upfront costs, can help you make a more informed decision about your new unit.
How Traditional Tank Water Heaters Work
A traditional water heater stores heated water in an insulated tank, commonly with a capacity of 40 to 80 gallons.
Gas burners or electric heating elements warm the water to the thermostat’s set temperature. The system reheats the water periodically to compensate for heat loss, even when no one is using hot water.
When you turn on a shower or hot water faucet, heated water leaves the top of the tank while cold water enters at the bottom.
If you use hot water faster than the system can heat the incoming supply, the tank may temporarily run out. You’ll have to wait for the water to reheat.
How Tankless Water Heaters Work
A tankless water heater does not maintain a stored supply of hot water. When someone opens a hot water tap, the unit detects the flow and activates a heat exchanger. A gas burner or electric element then heats the water as it passes through the equipment.
Because heating occurs on demand, the system avoids much of the standby heat loss associated with storing hot water. Once the tap closes, the tankless unit stops heating. This is one of the main reasons why many choose tankless water heater installation.
Tankless units are typically mounted on a wall and occupy much less space than a storage tank. However, every model has a maximum flow rate and heating capacity.
The correct size depends on how many fixtures may operate simultaneously and the temperature difference between the incoming cold water and the desired hot water.
What Are the Benefits of Upgrading to a Tankless Water Heater?
Upgrading to a tankless water heater provides your household with a consistent source of on-demand hot water.
- Endless hot water on demand: These units can provide a continuous supply of hot water for high-usage households and those with large families that take back-to-back showers.
- Improved energy efficiency: Because tankless units only heat water when you need it, there’s no standby heat loss, leading to lower utility bills.
- Longer equipment lifespan: Tankless units last between 15 and 20 years compared to eight to 12 years for standard tank units.
- Space-saving design: Tankless water heaters have a compact footprint, offering flexible installation options.
Are There Any Downsides to Tankless Water Heaters?
When it comes to water heater replacement, it’s important to understand the downsides of both unit types. While tankless water heater installation has many advantages, it also comes with some drawbacks.
- Higher upfront installation costs: Tankless water heaters typically have a higher upfront installation cost because they may require reconfiguration of your existing setup.
- Possible home upgrades may be required: Sometimes, you may need a new gas supply line, ventilation improvements, or electrical modifications to accommodate a tankless water heater.
- Hot water demand limitations: If you end up getting an undersized tankless unit because you didn’t consult a professional, it may not keep up with your hot water demands.
When Does a Tankless Water Heater Make Sense for Your Home?
Whether tankless equipment is worth the investment depends on your current system and household priorities. An upgrade may make sense in the following situations:
Your Current Water Heater Is Nearing the End of Its Life
If your tank is leaking, producing rusty hot water, making unusual noises, or failing to maintain adequate temperatures, water heater replacement may be necessary. Replacing aging equipment gives you a natural opportunity to compare tank and tankless options before an emergency limits your choices.
You Want Lower Long-Term Energy Costs
Tankless systems may deliver the most value for homeowners who plan to stay in their homes long enough to benefit from reduced standby losses and a longer equipment lifespan. The return on investment will vary based on installation cost, hot water consumption, energy prices, and maintenance.
Your Household Uses a Lot of Hot Water
Families that take several showers in succession may appreciate not being limited by tank capacity. However, high simultaneous demand is different from high total demand. If two showers, a dishwasher, and a washing machine frequently operate together, the tankless unit must have enough flow capacity to support them.
Tank vs. Tankless Water Heaters: Which Option Offers the Best Value?
A tank water heater generally offers better short-term affordability. A tankless system may provide greater long-term value through increased efficiency, a longer potential lifespan, and on-demand performance.
The best value depends on your budget, hot water needs, and how long you plan to stay in your home. Consider the upfront cost, expected lifespan, maintenance needs, and daily performance of each system.
- Want a lower upfront installation cost
- Prefer a straightforward replacement for your existing tank
- Have predictable hot water needs
- Are satisfied with your current tank capacity
Traditional water heaters often last approximately eight to 12 years. They generally require periodic flushing and anode rod inspections to control sediment and corrosion.
- Want to reduce standby energy loss
- Need continuous hot water for consecutive showers
- Want to free up floor space
- Plan to stay in your home for several years
- Prefer equipment that may last 20 years or longer with proper care
Tankless systems typically cost more to install. Converting from a tank model may require gas line, venting, plumbing, or electrical modifications. Tankless equipment also needs routine maintenance, which may include descaling the heat exchanger to remove mineral buildup.
Before making your decision, calculate your household’s peak hot water demand. A knowledgeable plumber can explain the installation requirements and help you choose the right system for your budget and daily needs.
