Cant get heating and hot water to work at the same time

[kap]

hi there,

My uncle has a system boiler and cylinder tank, he says he gets hot water on its own, and heating on its own but never both.

Any chance someone could point us in the right direction?

I've tried this site before and its been really helpful

Thanks in advance.
