This is way outside of what I have been reading here but you guys seem to be explaining something that is happening to me. I have radiant floor heat. It’s not grounded. It’s class 2. In one home it works great. However in my bathroom it give a static shock over and over when i touch the shower drain or tap handle. I was told that the home is not properly grounded and that is causing the static shock. Does this make sense or am I getting the run around? Again I know it’s not about computers etc but when you guys mentioned the static and electric noise I thought I’d ask.
