the heating works fine but , when you turn tap on its cold have to turn tap fully on but then water only gets luke warm

if you cant see a leak make sure the pipework on your heating {plastic} is the right type you have to have it with an oxygen barrier otherwise the atmosphere will absorb oxygen out of the water dropping the pressure in the heating system

You have a leak. Simple as that. If you cant find it or see it, possibly inside the boiler in the combustion chamber and is being evaporated when the boiler is on. Or Expansion vessel is faulty, would require repressurised or renewed.
