I’m trying to work out what I need to sort out the ventilation for my fish room, it's approximately fifty cubic meters containing about about 2000L of water. Being winter here with cold nights I’m getting major condensation problems on the windows and water collecting on the ceilings and then raining droplets. To try and reduce heat loss the room is pretty well sealed so adding to the problem. I also have installed a small wall panel heater to reduce the power consumption of the tank heaters at this time of the year.
It seems I have three options.. either a ceiling mounted exhaust fan, a wall ventilating fan or a dehumidifier, so what do I get...?
The ceiling mounted exhaust fan with a ball bearing motor is nice and quiet compared to the other options, however I have an almost flat roof with minimal space above the ceiling so have concerns it will draw the moisture up and then dampen the IBR roof sheets from underneath. It would presumably also suck out the precious warm air from the room, so more work for my heaters and pushing my winter electricity bill up further.
The wall ventilating fan is noisy and does not seem that efficient as have the same thing in my bathroom and shower. It’s also a mission to plumb requiring a large hole through the exterior wall and a vent outside.
The dehumidifier is fairly costly and then the most expensive of the three to run, it also makes quite a noise and would presumably have its work cut out with continuously not just sucking the moisture out the air but indirectly also out the tanks… or would it ?
Any guidance or wisdom appreciated !
