Seawind - Fan in HWS Compartment

[Bricky]

Another question for Seawind 1000 owners. Noticed a fan in the compartment behind the head where the HWS is located which was disconnected. Originally I thought it was to do with the gas detector which also was disconnected for some reason. Re connected the wires and the fan comes on when using water. Can't find anything on the net. Can someone tell me what it is for?

Apparently it's a legal requirement to ventilate the compartment when the HWS is fitted. Not a problem if they're both disconnected.

However, it is a nuisance as it comes on when any water is used, not just the HOT side of the mixer taps. I'd rather have the switch connected to the HOT flow side of the water heater. Nevertheless, we're not going without a hot shower on board!!

Thanks for that. Wasn't quite sure.
