Steam /condensation

[rc06bas]

Hi guys, had my rcz since May. Now its getting colder in the UK whenever I turn my heater to HI I get lots of condensation from the exhaust. I turn it to 20 and it stops? Coolant level also goes down if I leave it on hi? I know engineering but this baffles me.

Has the coolant system been opened & worked on for any reason?

I replaced the radiator in May.

If water comes out of the exhaust, it is entering the combustion chambers somewhere.

That sounds like a head gasket problem.
Is there sludge on the inside of the oil filler cap?

Have you had any overheating?

No over heating, no sludge, runs perfect with ac set to 20 thats why I'm confused lol

Drop in coolant may mean an air lock in system if no visible leak is apparent other checks to make certain are remove plugs & make sure there all dry?
