Hot cold water

[mblinko]

We have a Truma C6002 in our camper and of late when we turn the cold water, how water flows for 2-3 seconds and then it runs cold as usual. space heating is fine as it the volume of hot water. Anyone had this before ?

Does the cold water run hot from galley and heads taps or just from one of them? It sounds as though a cold pipe is in close proximity to heat somewhere (hot water pipe/hot air duct/oven). I have encountered hot water from cold tap in the galley after cooking due to the cold water pipe running behind the oven.

More so from the galley.

Good point, the heating is on all the time right now so it sounds like proximity of the cold pipe to the hot.
