Hey Fellow Wallies
I can't seem to find the bottom line on this issue and am wondering if you guys might help?
30 lb/hr steam boiler, electric, low pressure, used for process, (i.e. - no condensate return). They take cold domestic water, run it through a conventional electric water heater to preheat it to 85-90 deg F before it gets to the boiler. No pumps used here, it all works its way through on system pressure. I'm guessing that there's a PRV between the water heater and the boiler so that the boiler only gets 3-5 psi
Not a typical set-up, I understand, but it works for them. Question is - from a code standpoint, do they still require a blow-down tank, (which they don't have)? I'm interested in any jurisdictional areas but, specifically, this thing is located in Ontario, Canada.
