Okay, let me try to explain. I have a oil furnace hot water, with cast iron radiators. Last year I installed an OWB. I am using a heat exchanger which is in the basement next to the oil furnace. My problem is I have the oil furnace turned off. The thermostat is turned off, however the radiators are HOT! The circulator on the oil furnace is not on. The OWB is heating my domestic hot water. What is the problem? Is the heat exchanger heating my oil furnace water and it the rises? What gives? Please help!!
