hey lads,
i am currently installing a viessmann vitodens 100 35kw system boiler,my question is the boiler is 20metres away from the furthest rad as this is the only place it can go,the boiler is downstairs in a boarding school but is feeding an upstairs apartment,but is the pump incorparated within the boiler good enough to do the system or will i have to put a second pump on to drive it,i doubt the pump in boiler is big enough myself but was just looking for a second opinion,thanks in advance
