Can a Tankless Water Heater Save You Money?

Last updated on November 14, 2023

During a bathroom renovation, there comes a time when you have to choose between the tankless water heater and the one with the tank. Which one saves you money?

If you decide to install a water heater in your home, you might be wondering which kind would work best for you. There are two common types of water heaters: conventional storage-tank and tankless water heaters. They’re both great in their ways, but the latter may be a better option due to convenience and cost-efficiency. 

A traditional water heater with a tank requires more space in your household, which may be an issue in some cases.

With a tankless water heater, however, you’ll be able to enjoy hot water without having to generate extra space. If you decide to upgrade yours, check out this info about tankless water heater installation cost.

Despite its convenience, though, a tankless water heater may turn out to be an expensive choice—at least when it comes to upfront costs. If you’re planning to get one, you must evaluate the tankless water heater cost so you can see if it’s a feasible option for your household.  

On that note, while it’s expensive to purchase, is a tankless water heater still worth it? Will it be able to help you save money eventually? We’re here to help you find out.

Since a tankless water heater doesn’t use a tank for water storage, it only heats the water on demand. It doesn’t work throughout the day to warm up water inside the tank to supply to your sinks and showerheads. Since a tankless water heater only heats water when needed, you won’t need to worry too much about electricity consumption, making it an energy-efficient option for your home.   

Traditional water tanks heat up to 41 gallons of water per day that may be left unused, which costs more in terms of electricity consumption. Meanwhile, a tankless water heater will work only when necessary. According to the U.S. Department of Energy, an electric tankless water heater helps you save $44 per year, and a gas-fired tankless water heater saves up to $108 per year in energy costs. With this, you’ll be able to save a lot more money. You can even invest that extra budget for something more beneficial for your home. 

Moreover, most tankless water heaters provide an endless supply of hot water. This process is indeed beneficial in your morning and evening routines. However, this may also help you save money by protecting your health long term. When you have an uninterrupted or endless supply of hot water, there’s a lower risk of contamination, which is essential in preventing certain diseases such as diarrhea, cholera, typhoid, and many more.

A storage-tank water heater is bound to be used more often, and this can eventually cause faster wear and tear in its materials. Meanwhile, a tankless water heater only functions when it’s needed to, so there’ll be fewer repair costs as long as you maintain it properly.

The more you do the annual flush of your tankless water heater, the more you can help prolong its life, thereby saving you a lot of money on repair costs. 

Proper Tankless Water Maintenance Helps Save Money

Maintaining tankless water heaters is crucial for optimal performance and energy efficiency. To save time on upkeep, follow general guidelines and refer to the manufacturer’s specific instructions outlined in the user manual.  

Regular flushing, typically done annually, helps remove sediment and mineral buildup that can affect the unit’s efficiency. Check for leaks periodically to address potential issues promptly, and consider installing a water softener in areas with hard water to prevent mineral accumulation. Inspect the venting system for obstructions, damage, or corrosion; proper venting is essential for safe operation.  

Test the pressure relief valve annually to ensure it functions correctly. Familiarize yourself with the unit’s error codes to troubleshoot issues efficiently. While homeowners can perform some maintenance, scheduling periodic professional inspections is advisable to address potential problems and ensure all components function correctly.  

Various professionals can assist with tankless water heater maintenance. Licensed plumbers possess the expertise to handle tasks such as flushing the system, checking for leaks, and inspecting the pressure relief valve. HVAC technicians, specializing in heating, ventilation, and air conditioning systems, may also be proficient in tankless water heater maintenance, particularly if the unit is integrated into a larger heating system.  

Appliance repair services often have technicians trained to work on tankless water heaters, ensuring comprehensive maintenance. Additionally, manufacturers may have authorized service providers or technicians specifically trained for their products.
