Some TL boilers have an internal bypass that keeps the boiler isolated from the system until it reaches 140*...Heats very well.

    no internal bypass .checked literature, with low return temp would that cause the pipe nipples coming out of boiler to be that detoriated, two short nipples steel with union to copper no dielectric union.

    Probably

    should be piped primary/secondary at least. You could use a thermostatic union w/ bypass.

    The best way, IMO, would be variable speed injection w/ constant circulation on the system side.

    Definately


    should be piped P/S. TL wants no more than a 25 degree delta T and if you go over that, strange noises eminate from the boiler.

    An old gtravity system is perfect for constant circ and VS injection on OD reset. Toss in some TRV's and I can't imagine a better system.
