"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."

"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 amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

Price variations arise from size, type (tankless or tank), efficiency grades, and installation complexity, including labor and materials.

Yes, a heat pump water heater can work in colder climates but it’s much more effective where it’s warm. The reason is that the heat pump needs ambient warmth in the air to compress. The less warmth, the more compression required, thus using more electricity and offsetting the energy-efficient benefits.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.
