I have just installed a b&q split unit air conditioner.
I have connected the condensate drain (using overflow pipe) into a
rainwater drain, to stop the water on the floor outside.
any reason why I shouldn't do this - do I need a trap/air break or
should I just let it flow onto the ground ?
Personally, I'd make sure that the tube enters the drainpipe at a
point a good foot below the air conditioner if at all possible.
I suspect that the condensate drain pipe is merely connected to a tray
under the conderser and has no anti return mechanism and could flood
if you get heavy rainfall.
You could bet it drain on the floor but these things can produce quite
a flow of water in humid conditions.
Stick a small plastic box on the bottom to catch the water..
put a small aquarium pump in the box and pump the water over the condenser
This saves electricity and makes the unit more efficient.
I am surprised it doesn't do this already... it does claim to be A for
You can collect the condensate and use it in your iron to keep it clean.
Yes, but it's a major cause of the demise of air-cooled water chillers,
probably after 5 or 6 years life, outside the warranty, so the makers
don't care. Quality coils have copper tubes expanded into copper fins &
then tinned. They're expensive, so ali fins are a cheap substitute. I
have little experience of DX split systems, but the same theory
Not a problem with quality coils. Not many purchasers would read the
specification, all would read the price tag.
They're designed to a price & designed to sell. They sell.
I asked about this on a refrigeration forum and it didn't get the
Still if the AC is a heat pump type the outdoor unit will be able to
cope with condensate too, and have provision for collecting and
draining it making the above easier to try out.
