"It started off bad because I had the water heater installed, submitted my paperwork for my rebate for the installation and then my rebate ended up not getting honored because the water heater that was installed didn't qualify for Spire's rebate. Turn's out that the water heater that would fit my location as well as satisfy Spire's rebate, I would have had to wait 5 to 6 weeks for that specific water heater so, the owner of Hosack's Plumbing cut me a check for the amount of the rebate and the amount over time that the new water heater would have saved me. Not the perfect situation but, that was a win win for me as well as Hosack's Plumbing because a good water heater was installed just not one that would quite fit the Spire requirements for the rebate! Hence we didn't need to take a brand new water heater out and replace it with another water heater that was just .05 UEF Higher!"

"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"Jacob and Cody have been amazing to work with. We originally hired them to repair our stairs and have since contracted with them to install our kitchen tile floor, install electric in our kitchen island and to repair some of our drywall. Their team is very professional, their estimates are accurate and they do quality work. We plan to hire them again when we remodel our bathrooms."

Water Heaters questions, answered by experts

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.
