It was a late Saturday night. We had a super stubborn clog in some old galvanized pipes. Mr. Rooter send out Phil. Phil was great! He found the problem pretty quick.

Rose Bernard

Red Bank, NJ

We had a plumbing emergency and found Mr. Rooter while frantically searching for a 24-hour plumber. We feel like we hit a gold mine. Not only did we get a timely response. Everyone at Mr. Rooter was friendly, professional, competent and went above and beyond. Our plumber, Phil, was extremely helpful and gave us tips we could use moving firwars. Not to mention, the cost was extremely reasonable.

Joseph Chis

Hillsborough, NJ

Had sewer water backup in toilet and tub. Received callback as promised and arrived early. The tech determined we needed the main line to be cleared. He quickly located the opening and had us cleared in minutes. Very happy with the service. I was not prepared for the fee but it was an emergency.

Christopher Cox

Little Silver Township

Plumber, Phil, came out on short notice on a Saturday night and fixed our issue quickly, professionally and courteously. I contacted a different, well known plumbing company right before Mr. Rooter. The receptionist was rude and they didn’t call me back to say they couldn’t make it until after Phil left! The Mr. Rooter receptionist was very nice and they called me back quickly. I’m glad they did.

Rachel Turunen

Jackson Township

I was very happy that I went with Mr. Rooter’s. The service was very quick and up front. Jessie James was very helpful answering my questions and replacing my hot water heater. He was pleasurable to do business with. If another problem arises in my home, I will be using this company again.

William Holden

Brick Township, NJ

A thorough, professional, pleasant experience. I had a back-up in the 50 year-old pipes of my new home. I called Mr. Rooter to have them locate the blockage, snake the line, and then use their video snake to get a visual of the integrity of the pipes. I’m glad that I called and will use them again for future needs.

LarJ MarJ

Oakhurst, NJ

You get what you pay for. Edwin Robles of Central NJ educated me as a 1st time homebuyer on why and what he was repairing, prevention, PROMPT,(on a sunday at that!) clean, knowledgeable, super professional but DOWN TO EARTH and at a REASONABLE PRICE! Sewer pipes unclogged and main water line fixed. I was no longer crying once job was thoroughly executed. After all $#@* $tinks but somebody has to do it and I HIGHLY recommend him and this company for a job well done. THANK YOU VERY MUCH!!

Margie Rafferty-Criscione

Ocean Township

Absolutely lovely office staff! I always knew when the repair person was coming. Lorenzo our repair guy was awesome, I really don't think there is anything he can't do. He looks young, but don't let that fool you! So happy all the repairs are behind us. We really just did a one-stop shopping and decided to have everything we've put off fixed because it was such a tremendous experience!

How to Select a Water Heater

Mr. Rooter Plumbing takes pride in offering dependable water heater services backed by a satisfaction guarantee. If you’re looking for a tankless water heater replacement, do not hesitate to contact us for professional and budget-friendly service.

  • Determine Your Hot Water Needs

You want to install a water heater that will provide you with enough hot water for everyone in your household, even during peak demand. The most significant factors to consider when selecting a water heater are household size, peak demand, and appliance usage.

If you’re considering installing a storage tank water heater, a 40-50 gallon tank is enough for a household of 2-3 people. For every additional person, you should add 10 gallons to the tank capacity. A water heater that’s too small can leave you frustrated every moing when the demand for hot water is high. On the other hand, an oversized water heater can waste energy by heating more water than you need.

A tankless water heater is a great alteative to a storage tank water heater. If you’re experiencing frequent hot water shortages, it may be time to ditch the storage tank water heater and call a licensed plumbing service to install a tankless water heater. This type of water heater provides you with hot water on demand, saves you energy, and takes up less space. A professional plumbing technician will calculate the total flow rate needed for all fixtures and help you make the right choice.

  • Choose the Right Size

Select a tank size that can accommodate your household's peak demand. If you have consistent hot water needs, a tankless water heater can provide instant hot water on demand. Reach out to a local plumbing repair service for tankless water heater installation.

  • Consider the Fuel Type

Water heaters use a variety of fuel types, including natural gas, propane, electricity, and solar power. Natural gas is affordable and heats faster, but the installation costs are often higher. If you live in an area with limited access to natural gas, you may want to opt for propane. Even though it’s expensive as compared to natural gas, it is a reliable source of energy and can be used for various heating needs in your home.

Electric water heaters have lower upfront costs. In addition, the installation process is simpler, especially for tankless models. They also produce fewer greenhouse gas emissions. However, electricity is often more expensive than natural gas, leading to higher energy bills. When you’re choosing the fuel type, consider your local energy costs and environmental impact.

  • Evaluate Energy Efficiency

Energy efficiency is a non-negotiable factor when choosing a water heater. You want to install a water heater that provides you with sufficient hot water without putting a dent in your wallet. A higher EF rating indicates greater energy efficiency. If you’re considering installing a storage tank water heater, look for a well-insulated tank to minimize heat loss. Our plumbers recommend choosing an Energy Star-certified model for optimal energy performance. It’s a good idea to consult with a plumbing technician specializing in water heater installation in order to make an informed decision.

Mr. Rooter Plumbing is the plumbing company you can count on when you are in need of reliable water heater services. From tankless water heater replacement to new installations, we’ve got you covered.
