"I hired Posiden to convert my traditional water heater to a new tankless water heater. David was quick to respond, offered great prices, and completed the work when he said he would. Itâ s difficult to find reliable work but Poseidon Plumbing went above and beyond and did a great job. Iâ ll be calling them for all my needs in the future."

"Gabriel and his crew showed up when they said they would, and finished the work on schedule (new water heater installation). He came out the following day to look into an issue with the how water pipe going into the kitchen and didn't charge me, which I appreciated. I would call on them again for other plumbing work."

"Trio Heating and Air was an amazing company to work with! About a month ago I had Adrian come out and give me a quote on a new furnace for my home and he was so knowledgeable and easy to understand on what type of system I was needing for my home to lower my bill. We went with Trio and they scheduled the install to be done the very next day! Ever since then the furnace has been working so good they set the thermostat up just right I barely had to change it when it become cold outside. It was such an easy and fast process. I would defiantly recommend Trio Heating and Air for any for your heating and cooling needs!"

"After receiving a ridiculous bid from another plumber, I thought my old house was doomed to suffer another of my own bad repairs. David Allen saved me from that fate. Really great person and those he works with. Now he is saving the neighbor!"

Water Heaters FAQs, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the U.S. Department of Energy, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.

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.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.
