Weekly blow downs and make up water
Several discussions on boiler maintenance lately...
Does anyone have anecdotal evidence that boilers with float type low water cutoffs have shorter lifespans than probe type cutoff equipped boilers?
I’m asking because I can’t figure out the functional difference between adding a gallon of water per week through replenishing blowdown water vs. any other leakage.
If makeup water was really that bad wouldn’t we see the probe equipped boilers last much longer?
I add a little more than a gallon of water a week to my big system (18 rads, 860sq ft) which must be the packing nuts leaking steam (wet returns are brand new). The Big Mouth main vents also take some time to close once steam hits but that can’t be a gallon a week loss. Maybe a few ounces.
It was concerning before I realized that my last boiler had weekly gallon size blow downs for 20 years and was fine (junked to convert to gas).
