auto-feed on or off for boiler for hydronic baseboard heat ?
have a question regarding typical 100k btuh boiler feeding 2 zones and an indirect water heater. there is a watts auto-feed one-way valve which reduces pressure to ~15 lbs for the boiler, along with a stopper valve. And there is an expansion tank. I do not have a low water cutoff device.
What's the preferred practice for this stopper valve?
(a) should the valve be left on so the boiler always has an input of water and stays at the 15 psi of water pressure, especially since i don't have a low water cutoff?
(b) but i would think the system is not suppose to leak therefore once the system is pressurized and working that you could shut this valve off. this way if there is a leak you don't have a flood.
(c) i don't have a lower water cutoff on the system. if i did then would it be
preferred to shut the auto feed valve off? I also see articles about low water cutoff failure so it seems like a catch-22.
