Enlighten me on a couple of topics;
Why are you running water through a boiler, when the boiler is not engaged in the process?
Why is condensation a problem while the boiler is in service, but not a problem when it is idle but with water flow?
The Start up tech wants the pump and boiler wired separately- a switch for each. Directions were that if you turn the boiler off- let the pump run for a few minutes to pull out the heat from the exchanger to keep condensation from happening.
It was explained to me as follows by the start up tech-
Condensation in the boiler doesn’t occur when you have pool (tank) temperature water running through a non ignited boiler.
Condensation would occur when you have a low inlet temp and a high outlet temp. The mixing valve brings in a set 140* water into the boiler and with a 25* delta T giving us a target temp of 165*.
Condensation is what killed the previous two raypak boilers which used a ball valve as a mixing valve.
