I am about to start a job and I have a question of two.
I need some advice on piping the system here is what I have.
The home has oversized cast rads I am replaceing the boiler with a pinnacle and a triangle phaze indirect water heater.
I am also installing thermostatic valves (danfoss) on the rads I would like to do outdoor reset on the rads the boiler
modulates already and the owner wants to use tekmar controls.
Does reverse return make sense for this application? I am repiping the basement due to old leaks. Does anyone have a scematic and some advice on the near boiler piping. Constant recirc? I am installing a differiantial pressure valve any one better than others?
