Golly, it was only this morning and already I am answering. What a push over am I, said the bishop to the bishop.
Our air conditioner sits in a metal tray. If you have an air conditioner, you will know they drip water. The original units fitted to apartments in this building had a tray equipped with a pump to pump the water out of the tray and into the sewerage system. These have not been terribly reliable, but that is an aside as ours, being retro fitted, uses a different method.
The tray has a water sensor and when the water reaches a certain level, a heating element switches on and the collected water is steamed away, which is why the plate with the holes in it looks burnt. Under the plate is the element that looks much like an old electric kettle element.
It all works quite well, but in extreme humidity, water also drips from the pipes that run at the back of the system and fall straight onto the balcony floor and drip down below.
No one has been here when clouds of steam rise when water is being evaporated, but it could be alarming.
The rubber pipe is just the hose from the gas bottle to the barbecue that sits on top of the air con unit.
