"Signed contract 11/12. Permitting request made; permit issued 1/30/2025. Drywall/insulation work begun almost immediately. Spoke on phone with GC just over 2 weeks ago to review time frame for rest of work. GC stated he planned to meet with me and walk through the following week. Stated painting would begin the following week (this would be the week of 2/10). Neither event happened. Also asked about floor tiling job, as I had outside company doing the job & wanted to let that person know when he could plan on the job starting. GC stated 2 weeks out; that would have been this past week. This didn't happen either. I texted GC 2/18 to ask if we could meet at house the next day. No reply. Called cell # 2/19 requesting call back to discuss lack of recent progress. Emailed 2/21 with same request, reminding him that I'm renting a place & am unable to stay indefinitely. Again asking about time frame on project. On 2/22, texted again, asking that he please call me. Each time I've attempted contact, I've asked him to please call me to discuss project & time line. He has not responded to me at all. This is the reason for my complaint. As of now, I feel left in the dark about whatever is happening or not. He is not communicating to me. I feel like he is avoiding contact. At present, I have no idea what his plans are schedule-wise for the project. It feels like my house project is in limbo right now. For more than a week, nothing has been done inside the house, with no explanation as to why. I think the GC has possibly over-extended himself, due to the magnitude of people needing assistance post-hurricanes and therefore may not have much spare time. But he needs to make sure his customers are being taken care of and communicated with."

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.
