We are a small, family run company out of Roselle. We offer speedy service at a fair price. Estimates are always free. We treat you, and your house with the same respect we do family.

"Tim sr. and Tim jr. were two very personable men that worked well together. Highly recommend them for any plumbing needs. Quoted me a price over the phone, did a few extra things that I didn’t expect and just charged me the quoted price. I was very happy with what I considered to be extremely reasonable pricing. Had other quotes that were outrageous and wanted to basically replumb the whole house for no reason. I will definitely be calling them again for any other plumbing needs I have. Did an excellent job in a short amount of time to replace water heater and outside faucets."

"Jakubek did a great job on our basement remodel. David, Robert, Aric, and Tom showed up everyday on time, and were very polite, very quick, and very clean. They put down floor protection when they moved materials in and out of the house. At the start of each day they would explain what they were doing and at the end of the day we could walk through to check on progress and next steps. All of our requests were accommodated, and David was very responsive and flexible with change orders and a last minute decision that we made. Overall, the basement turned out great. It adds 50% more space to our house and provides a warm/clean place for the kids to play. If I could go back in time I'd hire David and Jakubek sooner."

FAQs for tankless water heater installation projects in Crystal Lake, IL

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.
