Transform your home with Anderson Design Painting. Our team of expert general contractors in San Diego specializes in kitchen and bathroom renovations. With our attention to detail and commitment to quality, we'll bring your vision to life. Contact us today for a consultation.
"Can’t say enough about the quality and excellence of Anderson Design! Our project consisted of updating 25 year old kitchen, enclosing our patio overhang into a California room and laminate wood plank flooring. After interviewing a number of contractors that walked in wanting wallet open and wanting $10,000 up front to discuss our ideas. Anderson walked in with vision, suggestions, ideas and many satisfied clients. We were listened to and offered advice. Even after adjusting our scope, the Anderson team came in to get the job done with 110% effort. We now have a professional kitchen (new countertops, appliances, glass tile backsplash) that looks out into the most GORGEOUS California room (walls, windows, 10 ft slider and laminate flooring). All of this was done for at least one third of the price quoted by other contractors! We would definitely use Anderson for any additional work around our home. Highly recommend! Happy clients are the best confirmation of the quality of service!"

FAQs for tankless water heater installation projects in El Cajon, CA
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.
