I just got a gas steam boiler for a radiant heat application. 1 season used Peerless Burnham model 61-03. It has the pressure controls so I need to convert to temp operation. I'll leave the low water cutoff in case there's ever a leak that flat out drains my system.
But I wonder what thermostatic control I should use? I see the Honeywell high low limit switches. My current electric Weil-McLean Electric just throttles on temp when pumps cool the boiler. I would like to do same. Sustain about 140 or 150 F water in boiler and kick on burners when it drops below 120 or 130 F. So that means I need a Differential Setpoint cut In and cut out sensor. Is there one unit that does this? Should I seek the same single probe setup in my Electric Unit?
I see the Honeywell L6008 low limit that would cut in the burner. If I get a 2nd one for high limit cut out, where do I stuff the bulb? I see one nice port in the boiler side with a 3/4" NPT plug. That only gets me one sensor bulb. I don't see a convenient dual setpoint Honeywell unit for low-high control.
Suggestions for a single part that can do both? Place to buy that is affordable?
Thanks in advance.
