Hi,
I have a Triangle tube cc125 boiler on the 2nd and 3rd floor of a 2 family home located in Boston. The combined living area is about 1,200 - 1,300 sq ft. There is about 200 linear feet of baseboard radiator running on a single loop through the 2nd and 3rd floor house.
The problem I am having is the thermostat never reaching it's set temperature. The thermostat (Nest) is located near the end of the loop. It was set to 66F but the temperature hovers around 62-64F (when the outside temperature the last two days has been around 20F). The parameter on the boiler is set to: Set Point Temp: 190F; Min Supply Temp: 120F; Min Outside Temp: 20F; Max Outside Temp 64F. As it is not reaching the T-stat temperature, this results in the boiler burning almost 24 hours per day.
I set the pump to the lowest speed in hopes of dissipating more heat from the system before it returns to the boiler but not sure what else I can do here. Any help or insight into the setting is greatly appreciated.
P.S. this is different than the short-cycling problem I am experiencing with my other TT boiler.
