Tankless Water Heater Service

How Do Tankless Water Heaters Work?

A tankless water heater is a type of water heater that heats water on demand, rather than storing it in a tank. When a hot water tap is turned on, cold water flows into the tankless water heater and is heated by a gas burner or electric element. The heated water then flows out of the tankless water heater and into the hot water tap.

One of the main advantages of a tankless water heater is that it only heats water when it is needed, which can save energy and money. Tankless water heaters are also known for providing a steady supply of hot water, as they can heat water quickly and efficiently. In contrast, traditional water heaters that use a tank can run out of hot water if they are used heavily.

Tankless water heaters are available in various sizes and capacities, and can be powered by either natural gas or electricity. Some tankless water heaters can be installed on the wall, while others can be installed outdoors. Overall, tankless water heaters are a convenient and efficient way to provide hot water for your home.

Tankless Water Heater Advantages

A tankless water heater has several advantages over a traditional water heater that uses a tank. Some of the main advantages of a tankless water heater include:

  • Energy efficiency: Tankless water heaters only heat water on demand, which means they do not need to constantly heat and reheat a tank of water. This can save energy and money on your monthly utility bills.
  • Endless hot water: Because tankless water heaters heat water on demand, they can provide a steady supply of hot water, even if you use a lot of hot water at once. Traditional water heaters with a tank can run out of hot water if they are used heavily.
  • Compact size: Tankless water heaters are typically smaller and more compact than traditional water heaters, which makes them easier to install in tight spaces.
  • Longer lifespan: Tankless water heaters typically have a longer lifespan than traditional water heaters, which means they can save you money over the long term.
  • Environmentally friendly: Tankless water heaters produce fewer greenhouse gas emissions than traditional water heaters, which makes them more environmentally friendly.

Overall, a tankless water heater offers several advantages over a traditional water heater, making it a convenient and efficient option for providing hot water in your home.

Magnificent indeed. Life savers.
Pipe going to my heater started to leak on a Saturday. Called a few places around and soonest appointment was Monday, which obviously is not going to work.
Magnificent was able to send someone in 20 minutes. Job done in 30 minutes or so.
Magnificent indeed.

Transparent pricing, clear communication, and quality service. Called, and was able to easily schedule a free estimate for a CCTV inspection, and from there was able to coordinate the work. I especially value their timelines as I needed to also coordinate with Castro Valley sanitation (CVSan) to ensure the inspector would also be there at the time of work.

Great to work with, would recommend.

Contacted them yesterday and they were available today at 1pm. They arrived on time and determined all I needed was to tighten a loose screw. Didn't charge me and was very professional. I had several plumbers within my contact list and all of them have been deleted, but Magnificent Plumbing. Great experience!

From the positive reviews on Yelp, I reached out to inquire about replacing the valves inside the toilet tank.  Julio arrived as scheduled and assessed that the parts & repairs would cost half as what a new more energy efficient toilet would cost because the toilet was positioned under a counter top and would need to be pulled out.  The  toilet was over 25 yrs old and would I like to take advantage of a promotion for a new Toto toilet.  The price was right for me so I agreed.  Julio and a co-worker returned as scheduled the following day for the installation that was excellent!  I highly recommend this company!

WHY WASTE YOUR TIME?!? Call MAGNIFICENT ASAP!!!! I am a realtor and needed a sewer and pipe inspection done for the house my clients are closing on. They answered and set an appointment with me in 4th of July! Awesome  points for that. Showed up and knocked out the work. Renee, the technician we were blessed with was extremely knowledgeable and respectful about being clean in and out of the house. Airdropped me videos asap and gave detailed explanations about any issues we did see. I really appreciate Magnificent Plumbing and hope to work with them again soon.

We've called them twice on short-notice to get a clogged sewer line cleared, and both times we got them here in ~12 hours or less. Their prices are fair, availability and responsiveness excellent, and they've taken care of us quickly in unfortunate circumstances.

My water heater broke down over the weekend.  On Sunday afternoon, I called the 24/7 help line. Connected with a staff member who scheduled me for an appointment first thing Monday morning.  By 1 pm on Monday, my new water heater was installed and operating beautifully.  The Magnificent Plumbing service men were prompt, polite and informative. I could not have asked for better and more timely customer service.  Great company!

Three years ago I had a plumber fix a leak under the sink. He surveyed our pipes and stated" all of your old pipes need to be replaced." I called Magnificent Plumbing for a second opinion.Renee, looked at our pipes and said " you're 86% good. . just some small recommendations".Magnificent has been our plumbing service ever since.This company is a gem. Renee and Edgar are skilled and reliable. Problems get fixed. Pricing is fair and reasonable.Good service. Good people.

Rene and crew did a great job with performing a trenchless sewer line replacement with minimal disturbance to the landscaping and no broken concrete. They handled all communication with the city, including permits, and were able to do the work without my involvement. As a courtesy, Sergio hydro-jetted the storm water line to help unclog a drain in the atrium. They provided a lower cost than the competition while also providing great service. They are truly magnificent.

Earlier this year in Jan, they also fixed a plumbing issue too.I like them for following reasons:--Rene and their team are honest--Reliable--On time--Very responsiveRene is the owner and he's great. Rest of his team who actually do the plumbing work is great too (like Sergio and Edgar).

Very happy with the work Magnificent Plumbing has done for us. They’ve installed new faucets in all of our bathrooms, replaced a toilet and fixed a leak in the kitchen sink. They are easy to reach, come on time and do great work. Definitely recommend.

I manage several homeowners associations and Magnificent Plumbing has provided excellent service and competitive pricing. Managing homeowners association I deal not just with one individual homeowner but with board members and all of the members of the property and I would highly recommend Magnificent Plumbing for your HOA needs or your individual needs.

I have been using Magnificent Plumbers for many years. They are extremely prompt and efficient. All of the plumbers I have worked with have been courteous as well as very knowledgeable. They explained my options and risks and benefits of each. I am disappointed that they have now started charging 3% for credit cards!

Magnificent Plumbing is one of my many vendors whom I can rely on day after day. They have a team of skilled plumbers who can do much more than just plumbing. I have used them for electrical, demolition, restoration, and sheetrock work. I know with Magnificent Plumbing the job will be completed in a timely manner and done right. The crew is responsible and communicate very well with myself and my Maintenace team. I am so happy to have found them.

Great job by the plumber. I was struggling hard to put a new toilet flange as was my fold toilet flange got rusted and then broken. I put a soft material around the PVC pipe and the screws were coming off and they are not holding strong to the basement. Plumber was very professional. Understood the problem and provided the exact solution that was needed for my problem.

The technician from Magnificent plumbing was great. The company came referred from my friend. They set my appointment according to my hectic schedule and, though they were a bit delayed from the time frame they offered, they called and texted to keep me updated. Upon arrival the technician was friendly and professional. He addressed our issue quickly and even checked out another plumbing issue we had in a different bathroom. I will definitely be calling Magnificent Plumbing if I have any other issue and letting my friends know too.
