Are Tankless Water Heaters Good? Pros & Cons
Tankless water heaters have gained popularity recently as homeowners seek more efficient and space-saving solutions for their hot water needs.
These innovative systems provide on-demand hot water, eliminating the need for bulky storage tanks.
However, before investing in a tankless water heater, we recommend you grasp the pros and cons of this technology.
How Do Tankless Water Heaters Work?
Unlike traditional water heaters that store and continuously heat a large volume of water, tankless systems heat water on demand.
When you turn on a hot water faucet, cold water flows through the tankless unit, where gas burners or electric heating elements rapidly heat the H2O.
This instant heating process allows tankless water heaters to deliver a continuous hot water supply in minimal storage space.
Energy Efficiency Advantage
One of the most significant benefits of tankless water heaters is their impressive energy efficiency.
These systems heat water only when needed, eliminating the standby energy loss associated with storage tank water heaters.
This technology means you won’t waste energy keeping a large water tank hot when you don’t need it.
According to the U.S. Department of Energy, tankless water heaters can be 24-34% more energy efficient than traditional tank water heaters for households that use 41 gallons or less of hot water daily.
Endless Hot Water Supply
Say goodbye to cold showers!
With tankless technology, you’ll enjoy an endless supply of hot water. Since you heat the water on demand, you won’t have to worry about running out during peak usage or when using multiple appliances simultaneously.
This advantage is helpful for large families or households with high hot water demands.
Space-Saving Design
Tankless water heaters are significantly smaller than their tank-based counterparts, making them an excellent choice for homes with limited space.
You can mount these compact units on a wall, freeing up valuable floor space in your utility room or garage. This space-saving design is especially appealing for smaller homes, apartments, or condos where every square foot counts.
Potential Energy and Cost Savings
While the upfront cost of a tankless water heater may be higher than a traditional tank unit, the long-term energy savings are usually substantial.
You effectively lower your monthly utility bills when you reduce your energy consumption.
Additionally, many utility companies offer rebates and incentives for installing energy-efficient appliances like tankless water heaters.
These incentives help offset the initial installation costs and make the investment more affordable.
Longer Lifespan and Durability
Tankless water heater manufacturers build them to last.
With proper maintenance, systems can last 20 years or more, significantly longer than the average lifespan of traditional tank water heaters, which is 10- 15 years.
This extended lifespan, combined with the potential energy savings, can result in substantial long-term cost savings for homeowners.
Consider the Higher Upfront Costs
While the long-term benefits of tankless water heaters are compelling, it’s important to acknowledge the higher upfront costs associated with these systems.
The initial installation of a tankless water heater can be more expensive than a traditional tank unit due to the need for specialized venting and gas lines.
However, when evaluating the overall cost-effectiveness of a tankless system, you need to consider the long-term energy savings and longer lifespan.
Addressing Potential Water Pressure Issues
One potential drawback of tankless water heaters is the “cold water sandwich” effect.
This situation causes a brief interruption in the hot water supply as the tankless unit adjusts to changes in water flow.
While this effect is usually minimal, it can be more noticeable in homes with multiple simultaneous hot water demands.
Proper sizing and installation of the tankless unit can help mitigate this issue.
Maintenance Requirements for Optimal Performance
Regular maintenance is necessary to ensure your tankless water heater’s longevity and optimal performance.
Tankless systems require periodic flushing to remove mineral buildup and sediment that can accumulate over time.
While the maintenance costs for tankless water heaters may be slightly higher than traditional tank units, the extended lifespan and energy savings often outweigh the extra expenses.
Sizing Your Tankless Water Heater for Your Home
Proper sizing is also critical when selecting a tankless water heater for your home.
An undersized unit may struggle to meet hot water demands, while an oversized unit can lead to unnecessary energy consumption and higher costs.
Choosing the right unit
Factors to consider when sizing your tankless water heater include:
- Number of bathrooms and fixtures in your home.
- Maximum hot water flow rate needed during peak usage times.
- Temperature rise required, based on your incoming water temperature.
A professional Woodland, CA plumber or tankless water heater specialist can help you select the correct size unit.
Gas vs. Electric Tankless Water Heaters
Tankless water heaters are available in gas and electric models, each with pros and cons.
Gas options
Gas tankless water heaters typically have higher flow rates and can heat water faster than electric models.
They are also more cost-effective in areas with low natural gas prices. However, gas models require proper venting and may not be suitable for all homes.
Electric options
On the other hand, electric tankless water heaters are more compact and easier to install.
They don’t require venting, making them a good choice for homes without natural gas or propane access.
However, electric models may have lower flow rates and require upgrades to your home’s electrical system to support the high power demands.
Venting and Retrofitting Considerations
Proper venting is essential for the safety and efficiency of a tankless water heater installation.
Gas tankless water heaters require specialized emissions to remove combustion gasses and ensure adequate air supply.
Retrofitting your home for a tankless system may involve installing new gas lines or upgrading your electrical service.
These factors impact the overall installation costs, and you should carefully consider them when evaluating the feasibility of a tankless water heater for your home.
Best Tankless Water Heaters for Large Families
Selecting the right tankless water heater significantly influences households with high hot water demands.
When evaluating options for large families, consider the following factors.
Flow rate
Look for a tankless water heater with a high flow rate (gallons per minute) to ensure an adequate hot water supply during peak usage.
Temperature rise
Choose a unit that can achieve the necessary temperature rise based on your incoming water temperature and desired output temperature.
Brand reputation
Opt for reputable brands with a track record of reliability and customer satisfaction.
