"We hired Rantz and his team to put in a whole home water filtration system and on demand hot water heater. The consultation was quick and easy. Rantz went though our options and was very knowledgeable. He had a team of two come out to the house the day of the install and everything went smoothly. Great guys highly recommend them."

"After looking at what was suppose to be done, and the entire job was evaluated, I was told I would be better off in getting a complete new water heater, and not put new parts in an 8 year old water heater, for once I felt like I was not ripped off, and given the best advice, and that is what I will do."

"The technician came and replaced my old water heater in 2 hours. He even ignored my dog was in her crate barking like a fool with no issues. My old heater was too heavy too take away so he came back with help to remove it. Definitely would have them work for me again. The price I was quoted was the price I got."

Water Heaters FAQs, answered by experts

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.
