So, I had an old heater/air conditioner for the 27 yr old home and
just had it replaced with a new unit. So, I just noticed a puddle
forming on the concrete over the past few months in the same area
where the air conditioner pumps out water. Anyway, the air
conditioner hasn't been on this year at all and the new heater appears
to be pumping out some water as the drip tube that exits out of the
house is dripping about 1 drop every 1 to 2 seconds.
Is this normal? It's annoying and it looks like it's going to ruin
the foundation over the next several years.
Heaters don't normally drip; unless they are hot water operated and
Air conditioners (and dehumidifiers) reduce the temp of the air which
is naturally going to remove the moisture from it!
That cooling and humidification, using electricity, is part of the
process's of making hot humid air more comfortable for humans.
The removed or left over moisture/water has got to drain somewhere and
all A/C installations should be designed to have means of disposing
it! Not just have it drip somewhere inconvenient or damaging! Can it
be directed into a roof gutter ground drain or onto a grassy area or
flower bed? In hot humid weather if the AC is doing its job there will
be quite a lot of it.
Each human body, alone, quite apart from other sources of moisture
within a residence, for example, breathes out etc. a considerable
amount of humidity each 24 hours.
Is the new unit high efficiency? I thought these would generate mostly
moisture the vents thru PVC pipe. Mine has a drain line on the outlet side
that I assumed was to drain the moisture that formed in the pipe during
operation. It connects to the same drain line the A/C uses, but I don't
know how much water actually drains since it goes into the floor drain far
enough I don't get any puddle on the floor.
The heater may not be making this moisture but you clearly have moisture.
If you have a crawl space or basement I'd start looking for signs of water.
You indicate that there is a water pump on your air conditioner so I'd look
there and then follow the the moisture to the source.
Is it a high effeciency condensing unit where the drain comes out the
furnace, its the same one for the AC coil, they drip. Mine drips but
it goes into a drain in the basement so it wont freeze out side during
the winter and stop my furnace from working, or just make a big ice
