Did water furnace or HVAC contractor share all or some of the cost on this design flaw fix? I was initially thinking the coil would power from zone board 24vac, but I not think they probably came from the circuit that powers the desuperheater pump. <br /><br />Another problem I had was that the contractor installed one of the ducts of the heat recovery ventilator on the discharge side of the furnace, so it was overpowering the ventilator blower and blowing conditioned air outside through the ventilator. He also installed the humidifier on the discharge which reversed flow when humidifier not on, heating or cooling the mechanical room, I have had both those issues fixedAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5090755192579086624.post-73344802985687394122012-06-19T20:43:13.299-04:002012-06-19T20:43:13.299-04:00Yes, I'm pleased with the solenoid valve as it...Yes, I'm pleased with the solenoid valve as it has completely stopped the thermosyphon loop.Davehttps://www.blogger.com/profile/17828298015984829723noreply@blogger.comtag:blogger.com,1999:blog-5090755192579086624.post-90116555967821835962012-06-18T21:46:50.898-04:002012-06-18T21:46:50.898-04:00I have this same problem with my Water Furnace des...I have this same problem with my Water Furnace desuperheater, I track the temps with a PLC and that is how I found the problem, I have not fixed the problem yet, are you happy with your solenoid valve solution? I assume that is powered by 24vac? thanks for any help. sloanebiking@yahoo.comAnonymousnoreply@blogger.com
