Chicagoland's Reliable Home Improvement Company servicing the City of Chicago and most suburbs. We specialize in full remodels of kitchens, bathrooms, condos and basements. We do not offer repair work or partial remodels. Celebrating 25 years in business.
"Miro redid our kitchen and half bath and we're thrilled with the results. We got a few quotes and ultimately went with Homewise Remodelers because the price was reasonable and Miro was so thorough in walking us through our options. He helped us select cabinets and worked through several versions of the kitchen layout until we were happy with it--we were easily able to swap out cabinet layouts and finishings, like adding a farmhouse sink. His crew were reliable, on-time, and respectful of our property throughout the remodel and we appreciated their attention to detail. They solicited our input on decorative details and were quick to fix things we didn't like, e.g., the location of kitchen cabinet pulls. We felt they treated our home as they would their own. The project even wrapped up a few days early. We would absolutely recommend Homewise Remodelers and choose them for future projects."

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.
