I finally had a chance to complete those changes you suggested. As you recall I had asked about the lack of flow in the system which required a drill pump to jump start. Your diagnosis was dead on. I replaced the braided hoses leading to and from the heater and all seems well. Flick the power switch on the pump and the system kicks in without hesitation.
I have to commend you guys once more on your after sales service. It has taken me about three years to build the house and I have been in contact with Radiant on and off as the various parts got installed and without fail I have found you willing to answer questions. I have dealt with three reps at this point and all of you have been equally forthcoming with information and help. I recommend Radiant to everybody who inquiries about my heating system.
Thanks for your help.
