"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."

"Service guy came as scheduled. Sent his "service" requirements to home base Home base calls back and lists, a very long list of what needs to be done and a very long list of what is not covered and what each item costs. The overall cost was outrageous and they weren't willing to give it to me in writing. Everything I had to pay for was overpriced, of course! They told me my other option would be to purchase my own water heater and they would reimburse me for what there water heater would cost, but no reimbursement for Labor, building permit, or any upgrades required by the local building department. The requirements of the building department were minimal. I went to Home Depot and had them do the installation and saved many hundreds of dollars. Lesson learned, have AHS do simpler repairs that don't require municipal building department approval. Have AHS pay for the equipment, and purchase installation from a trusted local installer."

Water Heaters FAQs, answered by experts

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.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

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.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.
