Understanding How Tankless Water Heaters Work

May 30, 2023

If you’re looking to purchase a new water heater, you’ve probably heard about the advantages of a tankless water heater. Not only are they more energy-efficient and cost-effective, but they also provide hot water on demand. However, before you make the switch, it’s important to understand how tankless water heaters work.

How Do Tankless Water Heaters Work?

Unlike traditional water heaters, which store a large amount of water in a tank and heat it continuously, tankless water heaters heat water as it flows through the unit. When you turn on a hot water faucet or appliance, cold water travels through a pipe and into the tankless water heater. The unit’s heating element heats the water as it flows through the unit and delivers hot water to your faucet or appliance.

The Benefits of a Tankless Water Heater

There are several benefits to using a tankless water heater, including:

Energy Efficiency: Tankless water heaters are more energy-efficient than traditional water heaters because they only heat water as it’s needed. This means that they use less energy and can help you save money on your monthly energy bills.

On-Demand Hot Water: With a tankless water heater, you’ll never run out of hot water. Because the unit heats water on demand, you can enjoy a continuous supply of hot water for as long as you need it.

Space-Saving Design: Tankless water heaters are much smaller than traditional water heaters, which means they take up less space in your home. This can be especially beneficial if you have limited space in your utility closet or garage.

Is a Tankless Water Heater Right for Your Home?

Although a tankless water heater has numerous benefits, it is vital to assess if it’s suitable for your household. Here are some factors to consider:

Upfront Cost: Tankless water heaters are typically more expensive than traditional water heaters. However, they can help you save money in the long run by using less energy and lasting longer.

Installation: Installing a tankless water heater requires a professional plumber and may be more complex than installing a traditional water heater. This can add to the upfront cost of the unit.

Water Usage: If your household uses a lot of hot water, a tankless water heater may not be able to keep up with demand. In this case, a traditional water heater may be a better option.

Maintaining Your Tankless Water Heater

To ensure that your tankless water heater continues to function properly, it’s important to have it serviced regularly. Here are some maintenance tips:

Flushing the System: Over time, mineral deposits and debris can build up inside your tankless water heater. Flushing the system regularly can help prevent clogs and keep your unit running smoothly.

Checking the Venting: Proper venting is essential for the safe operation of your tankless water heater. Make sure the venting is clear and unobstructed to prevent carbon monoxide buildup.

Inspecting the Unit: Have a professional plumber inspect your tankless water heater annually to check for any signs of wear or damage.

Bella is very knowledgeable about tankless water heaters. She determined that the heater that I purchased from Amazon was the wrong model. She went above and beyond the call of duty. She drove me in her car to the UPS store so I can return the heater and then drove me to the supplier store in San Jose (Pace Supply) so I can buy the correct one. She is very honest and showed me the wholesale price of the heater and used her coupon to get me the wholesale price. Umed, the technician, is an expert and did a great job installing the unit. He arrived on time, was very polite, and cleaned the area after his work was done. Bella and Umed put the customer first and provided an excellent service. I highly recommend United Plumbing because of Bella and Umed, their honesty, great service and expertise.

Technician Beck came on thanksgiving day, working from 3pm till almost 9pm, to replace a new water heater. In the middle of the installment, he even had to go back to his office and pick up new parts. It was very difficult to set up the tubes at my place since the space for the tubes/water heater was limited. Technician was very patient and friendly the whole time. The pipes after Beck’s work are better designed. I am very grateful they are willing to come on a big holiday like thanksgiving, getting the challenging work done without any complaints. Otherwise it would be a cold shower thanksgiving for us. Highly recommend.

United was quick to do an inspection and quote to replace our 20 year old tank water heater for a tankless and was able to start the job the same day. Professional and great service and the price was the lowest I received out of 3 or 4. Highly recommend!

Yuri was great! Yuri came to inspect the pipes that were hearing while the water is running but unfortunately we weren’t able to hear anything at the time of the inspection. Yuri was able to install a new faucet in my kids bathroom. If you are looking for a plumbing company use United Plumbing, from the office to the field the service was great! I will definitely use Yuri and United plumbing again in the future.
