Having a large garbage can full of ice water in your room is a bit of a pain. I decided to modify the system to run off a garden hose, for increased reliability and to prevent late night stumbles from flooding my room.
The system is fed from a tap on the side of the house. The hose is ancient so the connection is a bit leaky, but a bit of tape stopped that quickly. I added on some pipe insulation (~$1.50) around the garden hose to make sure the only thing warming up the cold water is my stupidly hot room.
The water supply in Waterloo is typically from groundwater sources, so the garden hose tends to be quite cold regardless of season.
The hose insulation ends under my window. The remaining length of garden hose is coiled and wrapped with towels to insulate.
The garden hose is then connected to the vinyl tubing with duct tape, of course. It then leads through a small hole in my screen towards the fan. I must congratulate my landlord on the exceptional job he does on basic maintenance, such as exterior paint touchups.
The tubing feeding the system cold water can be seen at the bottom of the window. Water circulates through the heat exchanger, and the warm waste water is pumped up towards the roof.
Another small hole was cut in the screen for the warm waste water line. It then passes an old bird’s nest (a necessary accessory for any student ghetto) and leads to the roof.
The warm waste water is pumped onto this garish prefabricated roof, which covers part of the backyard. Hopefully, a side effect of this is a slight temperature drop on the roof due to evaporating waste water. This may have a minor effect on the outside temperature near the room.
You can also pump the waste water into your eavestroughs. This makes sure you’ll be draining to a location that won’t flood your basement.
The water eventually drains off the roof. If you’re of the Zen persuasion, the gentle sound of running water will lull you off gently to sleep. If you aren’t, it may drive you absolutely mad until you realise that the sound of the fan drowns it out anyways.
The water drains to the same garbage pail, which can be dumped on the lawn or used for watering plants, if I had any.
