Plumbers installed fixtures (pedestal sink, toilet, steam-to-hot-water-converted radiator) in a bathroom yesterday. This morning we had only barely luke warm water. I found that they'd left the boiler feed to the indirect tank shut off. I opened it up, and we had hot water within a few minutes. Questions:
1) If that was boiler water and not DHW that was shut off, how could our hot water come back so quickly after turning it back on? Are the systems that good these days? (this one's actually eight years old)
2) I'm figuring that the feeder pump at that valve had been running full out for many hours since the indirect tank was calling for hot water most or much of that time. Plumbers shut the valve around 1pm yesterday; I opened it back up around 7 this morning. Should I worry that the life of that pump motor could be compromised because it ran so long with no water running through it, essentially burning it up? I suppose a mitigating factor is that the only hot water we used post-shut-off was dinner dishes and nighttime face-washing (wife and me). So maybe it didn't need to call for hot water for a while? FWIW, it's a 35-gallon indirect tank. And, if it matters at all, the water pressure coming from our well's pressure tank is 34 PSI. So, lowish.
I'm a total novice. Would be appreciative of knowledgeable feedback on this.
