"Was able to come the same day. He picked up and installed a new gas hot water heater and the Installation costs were very reasonable. Would highly recommend. He even called after the installation to make sure I was getting hot water and there were no leaks."

"When we realized our water heater was leaking, Aldo's was fast both to respond to the inquiry and to get us a replacement; within 36 hours, we were back to having hot water with a new tankless setup. Pricing was within the range we expected and the team was very communicative; I'd hire Aldo's plumbing again!"

"Edwin followed up quickly and set accurate expectations regarding his arrival time and project cost. Despite being challenged by an old, rusted infrastructure, he maintained a positive, can-do attitude. The work was completed in a professional manner; cleanup was complete. We have already identified opportunities for future engagement."

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"Dave saved us money and got the job done. Another company diagnosed the problem incorrectly and recommended changing a more expensive part that wouldn't have solved the problem. Dave did his own thorough assessment, found the real issue and fixed it right away. Couldn't be more grateful for heat and hot water. Thank you Dave."

"My old boiler was 53 years old! On its last legs. I got In town plumbings number from a neighbor who had her boiler installed by them. I called and the next day Guy was in my home assessing my situation. The next day I had a reasonable quote and the next week he was ordering my new boiler. He installed a new boiler and water tank in a day and a half! With his two employeesâ ¦.Frank and Carl. All these guys are amazing. Full disclosure I am a pain in the behind retired police officer. I ask all the silly questions. And Guy answered them all. This experience with our new boiler could not have gone better. I could go on and on. I highly recommend them for any plumbing situation."

"These guys are supermen! Fastest response I've ever seen. Called on a Saturday afternoon and had a technician working on my heater within 30 minutes. Very professional and experienced. Gave great advice. Will be calling them for all my plumbing needs in the future. Don't hesitate to call. Thank you to Lou and Jay for all they did."

Water Heaters questions, answered by experts

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.
