Understanding How Tankless Water Heaters Work

To better appreciate the benefits of tankless water heaters, it’s essential to understand how they function. Unlike traditional water heaters with storage tanks, which continuously heat and store a large volume of water, tankless water heaters only heat water as it’s needed. When a hot water tap is turned on, cold water travels through pipes into the unit, where it is heated immediately by either an electric heating element or a gas burner, providing an endless supply of hot water on-demand. This on-demand heating approach reduces standby energy losses associated with tank storage and allows for greater energy efficiency.

Comparing Tankless and Traditional Water Heaters

To help you decide if a tankless water heater is right for your home, it’s crucial to compare both tankless and traditional water heaters’ features and benefits. Here are some key areas of comparison:

1. Energy Efficiency: Tankless water heaters are generally more energy-efficient than traditional storage tank heaters, as they eliminate the energy loss associated with storing hot water in a tank. This translates to lower utility bills and a smaller carbon footprint.

2. Space-Saving Design: Tankless water heaters are compact in size, allowing them to be wall-mounted and take up significantly less space than storage tank heaters. This can be a valuable advantage for homeowners with limited storage space or those looking to maximize their living areas.

3. Hot Water Supply: While tank-based water heaters can temporarily run out of hot water after heavy usage, tankless water heaters provide continuous hot water on-demand. This means no more running out of hot water during back-to-back showers or while doing dishes and laundry.

4. Lifespan: Tankless water heaters often have a longer service life (typically 20 years or more) compared to storage tank heaters (10-15 years), making them a more cost-effective option in the long run.

Factors to Consider When Choosing a Tankless Water Heater

When selecting a tankless water heater, there are several factors to consider for optimal performance and satisfaction:

1. Fuel Type: Tankless water heaters can be powered by electricity, natural gas, or propane. Consider your home’s existing utilities and the associated fuel costs when deciding on the best option for your needs.

2. Flow Rate: Measure the flow rate of your home’s water usage to determine the proper size and capacity of the tankless water heater. The flow rate is typically measured in gallons per minute (GPM). An experienced plumber like John’s Plumbing & Drain Services can assist you in calculating your home’s flow rate requirements.

3. Location: Determine the best location for your tankless water heater, keeping in mind that it should be easily accessible for maintenance. Also, consider the distance between the heater and your home’s water fixtures, as shorter distances can minimize heat losses and water wastage.

4. Installation and Maintenance: Engage a professional plumbing service like John’s Plumbing & Drain Services for tankless water heater installation, ensuring proper setup and maximizing the system’s efficiency and lifespan.

Cost Savings and Environmental Benefits

Tankless water heaters can provide significant cost savings on utility bills, as they consume less energy than traditional storage tank models. This increase in energy efficiency can reduce your home’s carbon footprint, making a tankless water heater an eco-friendly choice. It’s also worth noting that, due to their longer lifespan and the absence of a storage tank, tankless water heaters generate less waste in terms of discarded materials and replacements.


Upgrading to a tankless water heater offers numerous advantages, including energy efficiency, space-saving design, endless hot water supply, and a longer lifespan. With the expert guidance of John’s Plumbing & Drain Services, you can confidently make the switch to a tankless water heating system and enjoy the many benefits associated with this modern technology. Keep in mind the factors to consider when selecting a tankless water heater to ensure optimal performance and satisfaction, and trust a professional plumbing service like John’s Plumbing & Drain Services for installation and ongoing maintenance.

Our water heater began spewing water this morning.  John was the first plumber in the area to answer my call, and was able to get to my house within 10 minutes of the call.  He fixed the problem promptly and for what seemed to be a reasonable price.  He was friendly and informative.  I will definitely call John again and will recommend him to neighbors.  Thanks, John!

John has done numerous plumbing projects around my house and has always done excellent work.  He's quick to respond to my inquiry's and even replaced my water heater on a Sunday.  Most recently, I had him install a water purification system and new faucet.  His prices are reasonable and he will continue to be my go-to plumber.

Project: Install, Repair or Replace Plumbing or Fixtures

Comments: I am very pleased. I've had John do the top priority job of repairing a leaking drainpipe and his work looks to be top notch. I'm definitely thinking of using him for the larger job of repiping the whole house (replacing the failing M-type copper with L-type). And again, John's bid is within my budget considerations. Highly recommended.

Comments: We had them run a snake from our sewer line out to the street, as we have lots of trees with roots that sometimes get into the line. They came as scheduled, did a great job and the price was as quoted.
