"My wife and I just purchased our first home. We knew before we closed that the water heater seen better days and the previous owner put it in a really tight spot, also backwards. After taking two showers, the water heater set off our carbon monoxide detector, having two kids this worried us a bunch. Halter Plumbing & Heating came out at 8:00 pm to help us, got it all figured out, and stuck around for a while to make sure it would be safe for us. Upon fixing it, I decided to go with a new one, like I said in the beginning, the water heater was in a tough spot, a lot of bad pipes, and backwards. He came in with the best price regardless of all the extra things he would have to do to get it in there. Besides that his price was definitely worth it, his willingness to take on the challenge of a backwards, crammed between a wall, and a fernes"

"Very glad I did it. I need a new furnace. There's a lot wrong with it. Found out it's almost 15 years old and could die during winter. The tech will get me prices on different ones and will go from there."

"We hired Areti to completely gut and remodel our master bathroom, as well as repair several other aspects of our home (replacing the foyer tile and swapping the closet flooring from carpet to hardwood, installing a new water pump system, resealing skylights, etc). When we initially researched Areti, we learned that it is a young business, but I would encouraged people not to worry about that because they know what they're doing and their work is good. Throughout the process they always emphasized they wanted to make everything exactly the way we wanted it so we would love it--and we do LOVE it! ALL of their employees were VERY friendly and approachable, so I was at ease having them in our home when we weren't there. They were also very prompt at getting back to us with any questions/concerns via phone, text, email, and app. They were always on time when we had an appointment face to face, and we especially appreciate how quickly they came out to fix our water pump when it failed (and this was not part of the original scope of work; but they tackled the extra work without a problem). The quality of their work seems good, however there were a few things that weren't done quite right the first time and that they had to re-do. They do warranty their work, so it didn't cost us more for those hiccups. And Josh and Isaac (who managed our project) seem very thorough in checking the work after its done. Josh also looked over our whole house, basement to roof, and made some suggestions for minor repairs we could do on our own to make our house more functional, safe, and beautiful. We would definitely hire them again for our future home projects. We are very, very pleased with all the work Areti did on our home."

Water Heaters FAQs, answered by experts

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

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.
