"Stay far away from this company. Original project went fine although it was expensive. However the past few months have shown me their true colors as I have tried to get some of the original work fixed. Be aware that they only warranty work for 12 months. We had the only four tiles on the step into our shower crack over the first year and I tried for months to contact them through email. No response. I finally left my name as a new customer, and they immediately called me (funny :)). They then asked for pictures and said they could fix it. I then discovered it would cost $600 to replace the four tiles they obviously installed incorrectly the first time. Correctly installed tiles would not all crack on the outer edge."

"Let’s just say communication was stellar from the get-go! We met with Tom to go over what work we wanted to do and there’s just something about making a personal connection with someone that makes you feel confident that the work they’re going to do for you is going to be great, and it was! Can’t say enough about Tom and his brother Jesse‘s professionalism, knowledge and skill!! Along with countertops, we were also installing some unfinished cabinets and we didn’t even know it was an option, but Tom offered without us asking to prime and paint them for us as well, AND he even went and matched the paint so the new cabinets matched the old ones we were keeping, which was great because we were under a time crunch to get this work done before family was coming to stay with us. Tom and Jesse worked with us to make sure everything was completed and that we were 100% satisfied in the short amount of time they had to get it done for us. Everything looks beautiful and we would definitely work with Tom and Jesse again in the future! Actually, hoping to have them come back and do some laminate flooring for us as well! Highly recommend these guys, they are great guys, great communication, 100% trustworthy and I guarantee they will do a great job for you!"

FAQs for tankless water heater installation projects in Maplewood, MN

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.
