During the warmer months you use your oil burner for domestic water, now it's time to fire up the coal boiler. So how do you fire up your coal boiler for the first time for heating season?
Do you introduce the cold water from coal boiler into your hot oil burner and take unnecessary chance. Or let oil burner cool down and let coal boiler heat up complete system?

I usually just shut one off and turn the other on...the circulator between them won't run below 150 degrees, so there is no worry about sending cold water into a hot boiler.

Let it cool down, or heat up the coal boiler before opening valves. If your boiler is cast iron, cold water into a hot boiler could break the boiler from thermal stress.
