"After an extensive process of having different contractors evaluate my home & submit their estimates for the installation of a Bosch tankless boiler/water heater combination unit as well as new baseboard heating, I selected AStar Heating & Cooling. Their staff impressed me from start to finish. Initially, I met Aaron who provided a thorough explanation of how the work would be done, offered other options that I did not know of or considered at the time, and provided a fair estimate that was similar to most of the other contractors. Next, when the time came for the projects to be completed, the technicians, Robert & Trevor, were on point. They always arrived in a timely manner & started working right away. They worked efficiently & quickly to get the projects done in the time frame promised. However, they did not rush, they took pride in their work & made every effort to make sure the work was completed neatly & done properly, as they thoroughly tested out the systems to make sure their were no issues/problems in their setup & performance. They also thoroughly answered my questions about the installation of the new systems as they went about their work. At the end of each workday, they made sure to clean up the job site & were very mindful in not dirtying my new floors by wearing plastic booties whenever they had to walk over them. The Bosch tankless water heater/boiler combination unit has been working without a hitch. I barely notice the difference in the time lag of receiving hot water in comparison to the old 40 gallon tank water heater I previously used. Overall, I highly recommend AStar Heating & Cooling. High quality work done high quality professionals. All of them put my mind at ease on what was a very necessary home improvement project."

"He did great work. So excited to have water pressure back in the kitchen. After having 3 other people look at it, he came up with a viable plan and was able to figure out what was wrong. Would highly recommend him."

"James did a great job installing a hot water heater. Stopped by the day before to see what he would need to complete the job and showed up early the next day to complete the project. Very personable, professional, and installed the new water heater with very few issues. I would absolutely hire James again in the future."

"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

Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.

No state requires you to vent an electric water heater. Other installation requirements for water heaters will vary, though, depending on the state and local jurisdiction in which you live. Some places require permits, while others don’t. Some may force you to place the appliance a certain distance from any walls or other appliances, while others don't. When you find a local professional to install a water heater, this expert will ensure you follow all the local regulations.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.
