| I just returned from meeting with a company that will be supplying me with a Lifebreath Clean Air furnace for my new 3000 sf home outside of Philadelphia. I am still undecided as to what I am going to use for my hot water source for the hydronic coil for heating and domestic hot water. He recommended the Quietside QVM9 unit that handles both. Anyone had and experience with this unit?
Thanks,
John |

We use a QVM9-150W1-NG for both hydronic heat (in concrete slab and attached to underside of subfloor) as well as our domestic hot water. We installed the system in 2005 and have been very happy with the functionality. The only reason I can think of that you could not use it for domestic hot water as well would be if you do not have sufficient water pressure. If the water pressure falls below a certain point, the domestic water heater portion will not function properly. Hope this helps.

The Quietside is manufactured in S. Korea with components not readily available here in N. America. Make sure the supplier carries a sufficient inventory of the Quiteside parts. |

We had an ignitor module go bad after the first year. We called up Quietside tech support. They walked us through a couple tests to determine exactly what the problem was and FedExd the part. We had it the next day, unplugged the old one, plugged in the new one and have not had a single problem since. I can't say enough about their tech supports professionalism and knowledge. So I can't say we've had the same experience as you with parts not being readily available.

| If we had a service call Saturday morning on a Quiteside boiler and needed a part, it wouldn't be available at our local supply house. The very best case scenario would be getting the part on Monday, if not Tuesday. |

I'd like to hear if anyone else had had a problem with the plastic fittings on the water supply line into the QVM9. We've had this fitting fail twice on our unit, which we use for domestic hot water. The first time was associated with high pressure in the water line that resulted from loss of pressure control on the well pump, presumably from lintning-induced damage to the pump controller.
The second failure followed within an hour of having our water softener system serviced. The pressure in our water system is set to 60 psi, which should be too low to produce any damage to the heater. The water system service adamantly denies that their service could have had anything to do with the fitting failure. I do not know enough the dynamics of the system to determine if the fitting was weak or defective, or if excessive pressure could have developed in the water supply sufficient to have caused it to fail. Any useful information would be greatly appreciated.

I'm assuming you are referring to the pipe and fittings that connect to the brass DHW inlet nipple. The first question is are you using pex into the the inlet with or CPVC? We have CPVC for the entire (inlet and outlet) of the DHW side and pex for the rad. heat side and have not had a bit of trouble with either. Other than the ignitor issue listed above, which they resolved quickly, I can say our QMV9 is one of the most maintentance free and reliable appliances in our house.

| I have a qvm9 i heat a 40 by 80 garage with it quite cheap to run except for the fact that i'am on the 3rd furnace in a year the first rusted out the exhaust chamber producing a code 10 and a water leak the second was broken in the same place the third did not have some of the o-rings in the water feed so it leaked to start with after running not even a month it also prduced a code 10 when it turned of the exhaust chamber was plugger solid with a white crystly looking stuff they drove a wire up in there to clean it out , it ran the hot water in the summer for another month and no hot water they came and got it working when i ask about replacing it with an actual furnace the said there couldn't be much wrong with it wow thats amazing its much cheaper for them to keep working on this furnace for nothing than to replace it with one that works i even offered to pay the difference for a working furce may be it was the 7 times i had to reset it between xmas and new years,apparently burning propane creates an acidic water that rusts it out , i don't think keeping on replace some thing that has a design problem is going to work so i hope #4 will break the circle |
