"Immediate Response did an excellent job, both by coming to my house immediately to replace a broken pipe for my sprinkler system that had caused water to get in part of my basement, and by replacing all the original shower and bath fixtures for my house.. I have a 1950's house, and those items were not standard. The had to find those types of fixtures for the shower, and the 3 faucet bathtub. Their pricing for all this was very reasonable, and was estimated and done by the job not by the hour. I am already set to use them again to start replacing more of the old pipes in my house..

"Mike did the replacement on the hot water heater. Was very nice,professional and wanted me to understand everything. Covered the floors....I just can't say enough good about him. In this day and age to have someone come to your house and be so nice and mannerly, clean up after themselves and be there the next morning, and I called the previous night? geesh...they were wonderful! I'm very picky...you made me happy.... Lorraine B."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

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.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.
