I strive to design the clients vision aswell as provide renovation services of a luxurious kitchen and bath of their dreams. I pay attention to details and I work well with my clients to build their project scope of work. My focus is quality and professionalism!
"I was looking for a pro who was experienced, honest and could communicate to get the job done right. Dave was the man. He knew what I wanted and suggested options to give the project(complete kitchen and bath remodel) a 5 star review. After my rental was completely destroyed from a tenant, I was up a creek without a paddle. Dave and Pablo went above and beyond to create the Reno I was looking for. From the first interview to the end result, I have no reservations for recommending ModernKnight for any project. They were on time , completely transparent and accommodating every step of the way. Are you looking for the pro to get your job done? Look no further, Dave is the guy! Thanks again Dave and Pablo for everything and more! Freddy."

FAQs for tankless water heater installation projects in Allendale, NJ
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.
