    replacing a Patterson Kelly steam water heater with a PVI

    We have 2 Patterson Kelly 08S heaters that are 20 years old each one has had the tube bundle replaced, spence main steam valves replaced,spence pilot valves with thermostat bulbs replaced, pilot solenoid valves replaced and high temp solenoid valves replaced. It has always been something with these heaters. If we replace them so we stick with them for ease of piping or has anyone used the PVI CSX steam water heater. It has a different operating principal. it needs no steam valve when you have 15 psi or less, I am looking for a little advice
    we need 180 gpm and no space for a storage tank

    I have no personal experience with PVI but I like to recommend you look into Cemline they make great units. http://www.cemline.com
    You avatar looks like a Superior boiler with GP or Webster burner, is that a VFD to left of the burner?

    Pvi has a terrible rep. The 2 250 gallon I manage rotted out in about 7 years. The installer worked for pvi and said they suck
