Thanks. Will call the geo man again, tired waiting for him to come back with answer. We, too, feell it is dangerous.
Make sure he is an electrician. The geo people are usually plumbers. Your problem might be located out of your house. The heating just made it apparent. They need to measure voltage drop when the heat is on and find what and where causes that. It might be potential fire hazard.
We live in a barn (aircraft hanger) converted to a house. 0.7 ac leaky pond.
