Bilge blower- defroster set up

Looking to get some info on bilge blower - defroster set-up.

First, how well does it work ?
What brand Blower ?
Is it wired to an on/off switch on the panel?


I know Squerly has this set-up...... anyone else that has a similar system, PLEASE chime in.

When it rains it fogs BIG TIME !

Thanks,
Doug

I have something similar to this and it works great. You need heat to get a good defrost.
