Central Heating

odd radiator system favours hot water over heating

After moving into our new home I noticed a problem with the gas central heating system. I had the boiler serviced and it was ok. I was told though that being ex services quarters my property's heating system favours the hot water over the radiators . This leads to stone cold rads but boiling hot water. We have bled rads, replaced 1 and introduced a cleaner. The rads upstairs are hot the pump runs and the pipes very hot. Any tips apart from replacing whole system? I was told I can replace the clock and rewire it to do rads first. Is this safe? Thanks.
