Yesterday I replaced a leaking isolater valve on my central heating system.
Since then the hot water gets luke warm
Then runs cold after seconds
Hot water tank is cold but pipes are hot
Any suggestions

By "isolator valve" do you mean 'check valve'?

If so, check valves are directional and it's possible you installed it backwards.
