"My tankless water heater went out on a Friday night, and the Water Heater Boys were able to replace it on Saturday the next day! Excellent customer service and professionalism. Will definitely call if in this situation again, and will tell my friends!"

"Pablo is very detail and quality oriented. He tried to explore options of repair before jumping into replacing to save me money. However. we end up replacing the water heater and he also took care of a pipe leak. He explore options and eventually installed a drain pump to make sure the work was done as per code (previously it wasn't).His work was very neat and left the area clean."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

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.

While heat pump water heaters are more expensive than gas-powered water heaters, the ROI is higher for heat pump units. Not only are heat pump water heaters more energy efficient, meaning immediate savings on your energy bill, but they also last longer than traditional gas versions, meaning you won't have to buy them as often.

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500

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.
