I installed oil fired heating in an old sprawling bungalow 2 years ago and have trouble getting water to the far end of run ,unless i shut off several rads at the boiler end of the system . i have tried balancing system several times but have concluded [maybe incorrectly] that pump just isnt man enough . no problems with air [ pump runs steadily and quietly at any speed setting] . i installed sealed system [unvented ] . system works very well apart from this problem . I used heat loss calcs to work out rad and boiler sizes . I am a level 2 plumber but never got chance to take level 3 .[how i wish i had]
Is it possible to add another pump further up the main 22mm run or can this cause other problems , any advice greatly appreciated
