"STAY AWAY. Numerous issues and they will cost you more money without you knowing it. I just found out that I was on a **DO NOT SERVICE** list (after all the grief they have given me.) I am ticked off. Here is a summary due to the character limit: 1. They installed a faulty HTP tankless hybrid water heater. I argued with them for what I think was a good year before a HTP tech finally determined that I was right. Replaced it with a Rinnai RUR199in. 2. They took (stole) my oval ductwork and replaced it. I was fine with the replacement. I looked the other way but it was expensive and they never asked - they just hauled it away. Most homeowners probably do not realize how expensive and unusual that oval ductwork is. I could have even recycled it at a profit. 3. I recommended them to a neighbor only to find cops all over their home one day. Their plumber stole their special needs kids controlled medications after having them go into other rooms to turn on and off the faucets. I just chalked it up to a bad apple. 4. HUGE ROOKIE mistake. They short-cycled the new air handler. Vent was right next to the main return (2in. away.) Unecessary wear and tear, high electric and gas usage, and discomfort. Whatever was coming out was immediately suck back in. Unfortunately I did not realize this until a couple years later. 5. HUGE ROOKIE mistake. They never installed the 2-stage wiring. See directly above. Look it up. HUGE discrepancies in temperatures and sky high bills. Premature wear and tear. I wrote Freddy Jr. about this which might be the reason why I am on their list. But still, that is their job to get it right and not mine. Most people would have no clue for the life of their system. 6. They did not hook up the high-limit kill switch/float on the condensation pump which led to a flood and destroyed antiques. I hooked it up in less than 10 minutes. 7. I was told one day that the original manger was fired because he was skimming clients from the company. 8. There is no check valve on the recirculation line which they installed on the new tankless they replaced. I believe it is code and now I have to hire someone else ([business name removed]) to fix their screwup which likely killed my internal recirculation pump. Again, unecessary wear and tear along with high energy bills. I was willing to look the other way on so many things but the truth is they get away with this because most homeowners do not know any better. In other cases, I figured that no one is perfect and we all make mistakes. But then to find out that I was blacklisted a few years later because I called them out on their BS after I needed their help yesterday? The only thing I can think is that I ended up costing them more money on things they should have done properly in the first place. It is a company that needs better oversight and apparently has awful management. I am not bragging but I have an advanced engineeering background creating petroleum engineering training material for big oil (aka plumbing on steroids--makes this look like childs play), programming, developing systems for hydroponics, working with heat and waste recovery systems, fixing combustion engines, and building computers for over 20 years. My point is that I noticed a lot of things that most people would overlook because I know how many things work. I called them out and that is the only explanation as to why I could have been blacklisted. But do yourself a favor and go with [business name removed] or [business name removed] instead. It is not to say that others cannot screw up, but this is my experience with them and the straw that broke the camels back. Mention that you read this here and thank you.

FAQs for tankless water heater installation projects in Danvers, MA

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.
