OK point taken guys, when a question is asked or point made I try to answer it to the best of my knowledge, as far as the waste of heat and danger, what would you call it when the conversation is about flames coming out of the stack of any boiler, I call it a waste of heat and very dangerous, Now let me ask those of you that have the Mahoning or any brand boiler that runs a TT wire out to the boiler to control the burn, is the temp of the boiler not controlled by an aquastat at the boiler as most manufacturers do? What would the benefit be of controlling the burn with a TT wire be
Slim, they do have aquastats yes, but they want there pumps to kick on and off with the fan in the forced air units in the home. This is how a lot of companies do it, mahoning, Taylor, hardy, legend, some shaver setups, acme, the list goes on
So when the thermostat calls for heat the pump is kicked on along with the fan,there theory is there saving wood by not flowing water all the time, but from what I've seen it's primarily due to there piss poor home made style underground piping. Around here they either don't insulate the lines and simply put them in casing, or at best wrap frost king around them
