Anderson Water-Power-Air is a family-owned business serving New York State, providing the highest-quality products and service available in the industry.

"Tom was great! The installers were exceptional. Good clean install. They even rescheduled us..... for 2 weeks earlier than set appointment. Easy payment terms. We elected to pay a substantial amount down. Tom showed us many generator options. We checked everything and selected the best option for us. No pressure sales tactics. THE INSTALLERS DIDN'T GOOF AROUND EITHER. THEY DID THE JOB AND CLEANED UP AFTER THEMSELVES. Thank you."

"I recently had a new furnace installed by IJN Eastside. I was very pleased with the experience from start to finish. The process was smooth and professional. The team arrived on time, explained everything clearly, and completed the installation efficiently. The new furnace runs quietly and heats my home much more effectively than my old unit. I also appreciate that they took the time to clean up after the installation and ensure everything was working properly before they left. I had three estimates done, and IJN Eastside was by far the lowest. If you're looking for a reliable HVAC company, I highly recommend IJN Eastside for a hassle-free furnace installation."

"Endor Group did our master bathroom and we were so happy with the results! They replaced the flooring, vanity, installed the shiplap and tiled the shower. Noah and Dane are incredibly efficient, meticulous, and detail oriented. They worked very well as a team and made sure I felt involved. At the end of each day they also made sure to clean up and organize. The pricing for my bathroom was very fair as well. I’d recommend them to anyone that needs work and wants quality results!!:)"

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
