"This review is a long time overdue but I really wanted to give Stuart and his team a shoutout for the great job they did. I had Pipeline to come out to Waianae to install 2 toilets and a shut-off valve at my home. Not only were they willing to come this far, but also, Stuart and his team gave the absolute best customer service where nowadays it is rare. His team was fast, clean, respectful and efficient and his pricing very fair for the job. One toilet installation proved to be trickery than anticipated, but they went the extra mile to get the job done. And when it came time to do the shutoff valve, I really was fully frustrated with finding the public water source. However, Pipeline's team member was persistent and got the job done all while maintaining a great attitude. I would definitely recommend Pipeline Plumbing. As a landlord, I have been through my share of repairs and good companies like Pipeline are essential and just plain sanity saving."

"When I was told the cost of the job would be $505.00 plus tax, I was shocked. He told me that the price was set by the company. I had $60 coupon, so it came out $465.00. Since he’s already at my home, I gave him ok. I couldn’t send him back because I was afraid there would be a charge for the visit whether I use his service or not. The job took approximately 30 mins excluding time he spent loading and unloading his tools. I felt so stupid for paying that much for 30 mins job."

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.
