It could be because of lottsa stuff... leaks or drips from hoses or connections, a pinhole in the rad, leaking at thermostat housing, duff pressure cap or....... the HG.

Water alone isn't ideal, but it should not disappear.

^^^ +1 ... check the cap first to be well tightened. ... there must be 1.4 bar in the system to increase the boiling point to 120*C

Have the cooling system pressure tested whilst the engine is cold - this is a very good way to fins small leaks that normally disappear as steam when the engine is hot and running - often leaving no evidence.
