heating problem

[jackthefixer]

hi all,

i have a small problem.

i live in a 4 bed detached hoise. but since we moved in, never have all the rads worked together. they all work, but not together.

if i turn off the water feeding the copper cylinder, i'll get 2 more rads to work, and so on,

someone told me the pipes taking the hot water from the oil burner are too small. ie not enough water in the sytem, its a closed system.

the house was built in 2000, and i'd imagine this would be a silly error if its true. no exra rads have been added to the system, so why wont it work?

if this is the case, wat can i do?

would a bigger pump help?

help please,

Jack

the pipes may be too small, or the boiler.
could need balancing, or cleaning or pump may be dying etc

System needs balancing. Setting the heating and dhw at separate times will improve performace too.
