What Are the Benefits of a Tankless Water Heater?

Tankless water heaters heat water on demand, which means no standby energy loss and an endless supply of hot water. They also take up less space and typically last longer than tank models. It’s a great option for homeowners looking to cut energy costs and modernize their system.

How Long Does a Tankless Water Heater Last?

With proper maintenance, tankless units can last 15–20 years or more. Routine descaling and inspections help extend the lifespan and maintain performance. We offer maintenance services tailored to your unit and water conditions.

Is My Home a Good Fit for a Tankless System?

Most homes can be retrofitted with a tankless water heater, but factors like household size, water demand, and existing plumbing setup matter. We’ll evaluate your space and recommend the best option. In some cases, a traditional unit may still be ideal.

Do Tankless Water Heaters Require Special Maintenance?

Yes, they should be flushed regularly to remove mineral buildup—especially in homes with hard water. This helps prevent clogs and ensures your system continues to run efficiently. Our team offers affordable maintenance plans to keep everything on track.

What Happens If My Tankless Water Heater Stops Working?

If your system isn’t providing hot water or showing an error code, call us for a quick diagnostic. We can often resolve issues like ignition failure or scale buildup on the spot. Check out our repair services for more details.

Will I Save Money With a Tankless Heater?

Yes, many homeowners see lower utility bills because tankless units only heat water when needed. Over time, the energy savings can offset the initial installation cost. They’re especially efficient in homes with moderate to high hot water usage.

How Long Does Installation Take?

Most installations can be completed in a day, though complexity depends on your home’s plumbing and energy connections. We provide a detailed schedule and quote before work begins. Our team works efficiently to minimize downtime.

Do You Handle Gas Line or Venting Modifications?

Yes, we take care of all necessary upgrades for proper installation, including venting and gas line adjustments. Safety and compliance are always a priority. We make sure your new system runs flawlessly from day one.

Jeremy the owner is a stand-up guy. He obviously cares about doing a good job, and that culture is reflected with his employees as well. He is knowledgeable and honest and I would recommend Advocate to any of my friends and family who needs a plumber.

I saw water bubbling up between our meter pit and the house. A friend recommended Advocate Plumbing. Jeremy sent a tech out immediately to confirm the break, gave me a quote, and scheduled the work for the next morning. The crew arrived on time and completed the line replacement and interior work in less than 7 hours. They were all professional and polite. They cleaned up after and minimized damage to the yard. Like my friend, I will not hesitate to recommend Advocate Plumbing to anyone.

We reached out to Advocate after receiving some unexpectedly large estimates from a bigger plumbing company. Advocate came out to estimate and gave us a home inspection while they were here. Their estimates were much more in line with what we expected based on our research. They were able to get us scheduled very quickly and did an excellent job while they were here. We had quite a few things to be done, so Zach was at the house for a few days in a row. He was exceptionally friendly and professional, and ensured we were happy with all of the work that they did each day. He was able to help us troubleshoot some more tricky issues which we really appreciated. We really liked how in the loop we were kept throughout the whole process. We 100% recommend Advocate (and Zach) to anyone looking for plumbing work to be done! We will be using them going forward for all of our plumbing needs. EDIT: Adding in that Jeremy (the owner) also came out one of the days to help take on some of the work we needed done. He was also a pleasure to work with!
