Ideal Delta T

in THE MAIN WALL
I have a TT Solo 110 heating 9 ci radiators on 2 floors, converted gravity system, with outdoor reset. Right now I have a delta t of about 30 running the circulator at its lowest setting. Is this good or should it be a smaller delta?

    Comfortable ?

    If so that delta will work so long as the rooms are heating well.



    Is the boiler piped direct, or primary secondary? If primary secondary is that the boiler loop delta?

    Heats well with delta-t at 30

    Piped direct, no primary/secondary. Heated ok with delta-t at 18 to 20 also when circulator on higher flow rate. I just thought the higher delta would create more condensating which would be better for the boiler.

    Higher

    delta T is good so long as you stay comfortable. Just make sure you adhere to the minimum flow rate on the TT Boiler. You may have to play with the water temp versus the delta T to achieve this.
