"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

"I had a request of changing a rigid water line to the toilet to a flexible water line and Domingo came on time (almost early, even!), assessed what needed to be done, came back with his tools, and was done in not even 15 minutes! No leaks, kind, and professional, would 100% have in my home again for another repair."

"This was probably my best experience on Angie's List. I woke up and noticed there was no hot water in the house. Went to the basement and noticed the hot water heater was leaking. I called up Advanced Professional Plumbing, told them what was going on and gave them the specs of the hot water heater. 20 minutes later a technician showed up (a very nice guy named Joey). He inspected everything and showed us the cause of the issue. He gave us a few options on what to do and we decided to replace the 75 gallon hot water heater. Within an hour, Joey came back with Sam and they replaced the old water heater with a new one. They were both professional and got the old hot water heater without making a mess and replaced with a new one. After the job was done, Joey tested all the bathrooms out to make sure the pressure was good and we paid and they were on their way. They were fast, efficient, explained everything and it was a great price. You really can't beat that. Your hot water heater breaks down on a Saturday you are not expecting hot water for the rest of the weekend but Advanced Professional Plumbing delivered. I appreciated the office following with me to make sure everything went. Just an overall class business."

"Travis and Elvis were very professional on the phone. Travis provided detailed information and answered all of my questions to better help me understand between options when I was choosing a new water heater for my home. Travis provided me with a free estimate and stayed within the price range we agreed to when completing the job. The water heater was installed in a timely manner. I also received a follow up phone call to check how the water heater was working and if I had any questions which I appreciated. I would definitely recommend hiring this company and plan to use them again in the future."

Water Heaters questions, answered by experts

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters—both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.
