Hot water Run for heating

In one class, I remember having learnt that hot water run on wall radiators shouldn't be more than 70 feet. Even if booster pumps are placed - there is not enough energy to travel.

May it be confirmed please.

Thanks

    Not that simple

    It could be that if a designer prefers a certain circulator, specific pipe size  and  a set number of emitters on a loop that it works out that 70' is the max.

    In reality it really depends on the individual system. There is no magic maximum number. It just depends on the requirements of the emitter and the pipe size and circulator being used.
