Electrically-operated flu damper (GVD-5) on my gas-fired boiler system failed (again) and the service tech has no love for these. A little more efficiency but a reliability headache, he says. He bypassed it to get us through the day but when I asked whether it should be replaced, he could not exactly say no, but it was clear that he would leave it bypassed.
Thoughts?
