"Who knew how entertaining and informative having a water heater installed could be. After several snaffus and a comedy of errors through no fault of his own, Micah with great determination installed a new water heater. He showed me what he was doing each step of the way and explained why he was doing it. Very professional job. He cleaned everything up when he was finished and hauled away the old water heater. It's refreshing to have such professional, caring contractors do the work because they genuinely care and want to do a good job. I have already told several people about my positive experience and they were very impressed."

"Andrew was very knowledgeable and thorough in explaining to us the differences and advantages about converting to a tankless water heater. The installation went smooth and as of now we are happy customers and would call them again if we needed."

"The yearly service works out to be $50 a month. We've had two water heaters replaced through them because of a fault in them. They're usually very responsive. I like that I can request the service online. The only thing is, I wish that there was a better avenue for emergency services. If something doesn't work right away usually it takes a couple of days to get someone out and sometimes you can't wait two days without water."

"I tried to fix my own sinks, but ended up having to turn off the water. I called Integregity Plumbing late Wednesday night. Steve was over first thing the next morning. He was prompt and friendly. Not only did he fix both sinks and restored my water, he brought both my bathroom sinks up to code. While he was working, I asked him several different questions about other problems I had in my house. He was very helpful. If I need any other help with plumbing problems, I will definitely call Steve again!

Water Heaters FAQs, answered by experts

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

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.

The average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.
