What To Do When Your Quietside Boiler Goes Quiet

A decade ago a Pacific Rim manufacturer developed a product called the Quietside Boiler and Quietside Water Heater. The typical scenario unfolds with a well-dressed salesperson entering your home with the goal of selling you a product. They may be entirely polite, dressed in a white shirt, and begins to “listen” to your list of wants and needs for a home heating/hot water solution. After the conversation progresses, the salesperson recommends a seemingly cost effective solution that will give you “endless hot water, at a massively reduced cost”. You feel excited at this prospect and sign on the dotted line.

Now let’s fast forward to the first bitterly cold day after the installation. You get up in the morning and the house is unusually cold. You go to where the unit is installed and you’re greeted with a symphony of blinking lights and an increasingly large puddle expanding quickly on the floor. The first reaction most people have is to furiously call the company that installed the product. The person on the phone is extremely empathetic and dispatches a technician to your home.

The technician arrives and goes through the motions of what you believe to be diagnosing the issue, cleaning up the mess and promising that the issue has been resolved. The company honored your warranty and they left you with a feeling of satisfaction. Everything seems to be going well, the unit is functioning well and suddenly, a few months later and the problem happens again. That same feeling of horror and anxiety comes over you as you see the same panel of flashing lights and an even bigger puddle of water soaking through again.quietside

You call back, the technician tells you he must order parts from the manufacturer after being in front of the unit for two hours with a puzzled look on his face. The problem appears to be repaired again. Yet this isn’t the end of the frustration and the annoyance. The company that produced the product is no longer supporting the installers and it seems the Quietside manufacturers have gone quiet.

They have gone out of business. To add insult to injury, the U.S. Consumer Product Safety Commission issues a recall November of 2014 stating that the water heaters can overheat, posing a fire hazard. There were over thirty-five reports of units overheating and some that even caused burns on the wall and property damage.

Patriot Water Heater has developed a solution to replace the Quietside unit with a Lancaster, Pennsylvania based company that has designed, engineered, assembled and supported the product. A Burnham gas-condensing boiler manufactured by U.S. Boiler.

We have built an exceptional relationship with the U.S. Boiler company. We have been to the factory, trained at their headquarters and have received invaluable support contacts. Through this relationship, we are confident in the performance and reliability of the product and always aim to avoid the situation where the customer is left with an unsupported, underperforming product and to alleviate any anxiety that they may have.

We start with the design process to calculate what the heating and hot water demands are for you and your family. We stand by the manufacturer because the manufacturer stands by us. Through this relationship, we can provide excellent products with unparalleled service.

    I myself purchased (3) units and install 2 units in a two family house and 1 unit inside my own home. I had nothing but issues from the start to finish. The pumps would stop working with little to no reason. The main board crapped out. The air switch went bad. I had so many replacement parts swapped out over and over until they would not honor or provide me any new parts. I had tenants who had no heat for periods of time and no hot water. I’ve had to credit them rent monies for hotel nights. I had to replace all (3) units. Of course in the winter time why would i have any luck with some warm weather when they went down. I did everything to letter of the law as the install required. I have pictures of two units side by side with the best plumbing to support these pieces of Garbage. This company for obvious reasons went out of business. These things are COMPLETE CRAP!!!!!
    They made the worse possible combo unit and i was the sucker who went all in and bought (3) DPW -99. That said i can offer anyone who needs parts any of my three units if you want this shit. I was forced to replace them because no heat no hot water. I spoke with many many people during this nightmare and i decided to use that Navien NCB-180 as replacement. I’m very happy with them
    Right from the beginning you can see the difference and you can tell the unit is made correctly. Navien also stands behind their product support and will assist you, unlike Quiteside. They will even warranty any of there units sight unseen from the dealer and reps i have spoken with(YES Reps – Real People). I can’t tell you how many hours of my time and how much i paid my plumber for this nightmare but believe me its in the 10’s of thousands of dollars. I can only hope people read and learn from my story before buying any high efficiency boiler. There are many great company are out their now like this company says. You get what you pay.
    Good luck to all

    I have a DPW-120B and just this last few weeks have noticed a bit of water on the floor under the cold water outlet pipe and the unit is flashing a code Ab , which shows as an abnormality of the central heating temp thermostat. I talked to the guy that installed this unit 4 years ago in my new home, and he told me the company went out of business, but he could install another Bosch unit for $4,000.00 Like I have the money to pay for another unit!! This unit I have cost me $5000.00 to have put in at the time my house was built. How do we get anything out of these companies when they close shop and another company (Samsung) buys them out?

    Do you know any technicians in northern NJ. Have 7 Quietside units in an apartment building

    Our quietside went quiet last year. We still do not have heat, due to financial issues. Put in a water heater for water. Have used electric heat in the winter. Looking to have this junk replaced to have it used only for the baseboard heat. It was such a big investment it lasted 2 years. The first time it flooded the basement. The tech came and replaced a part. The second time it flooded the basement it stopped completely and well the company tucked tail and ran away. Leaving us with a waste of money hanging on the wall and no heat or hot water. It has been a nightmare for sure.

    Is there ANY recourse as a homeowner who has one of the POS units? I was told by my service company today that the parts are impossible to get.

    Request for help finding a part.

    Hi. I am looking for a part for my Quietside tankless water heater. I’m hoping you can help me, if possible.

    Its a Air Vent Outlet Pipe. Its a copper pipe that connects a 3 way valve to a heating flow sensor. It’s about 10 inches long with a 90′ bend in it.. The part number is C21708267A and is item #14 on the parts list of the Installation Manual.

    The model number of my unit is QVM9-90W1-NG.
    Serial #5959-20051026-2019

    Mine was accidentally discarded during a repair. I’m having a very difficult time finding a replacement.

    Please reply. Thank you

    My 120A just started throwing Ad code as well as A4. I’ve cleaned the condensate trap out, switch out the air switch (from another POS unit) but still get the Ad code? For the A4 code, cleaned the space heating filter. Still throwing the codes and shutting down. If anyone has troubleshooted these I would be in debt for some guidance!! thank you
