OK, so I have an oil-fired Weil McLain boiler for both baseboard heat and hot water. The coil was starting to go, and was very unpredictable, so we decided to add a gas hot water heater.
We just cut the in/out to the coil and re-routed to the new water heater. My question is this - what about the control mounted on the coil? Do we need to disconnect it?
