m***y 发帖数: 14763 | 1 You mean, for a wet basement, right? Because we can't install a sump pump
for a wet backyard.
Improving drainage is more desirable. Sump pump can remove the water in your
basement, but the hydrostatic pressure is still on your wall, along with
the humidity, it can does a number on your cement basement. |

RH between 40% and 60% is the best depending what temp you set.
My house is 72 degree and 50% Humidity all year round. |

m***y 发帖数: 14763 | 6 Hope it's just condensation.
Tape a small patch of film on the ground, and observe which side the water
is on. If it's on the upper side, then it's condensation, and try to reduce
the humidity (again, in most cases, there's not much you can do except
installing a dehumidifier.) |

C*******d 发帖数: 15836 | 7 I set mine to stop at 60%. I feel quite comfortable with it and have no
problem with mold etc. Many people suggest lower, say 45%. The bottom line
is: if your basement humidity level is 70% or higher, it is better for you
to have one. |

temp between floors and rooms.
Temp setting (on thermostat) will determine when ac compressor work and how
often they work, they help lower the temp and also take out humidity.
Compressor use a lot more electricity than the blower fan.
If your house is zoned, turning fan to on all the time will not help much
and could waste more electricity.
If you have a multi-story house with only one ac unit, leaving the fan on

J******u 发帖数: 680 | 11 i hate laminate. It is hard to clean it because the lump may occur if the
surface is too wet. Also if the air is humid, the laminate may get sticky
and keep your feet print on it. Very ugly. We installed laminate in three
houses. Same problem above. |

n*******e 发帖数: 55 | 12 The house we are interested now has a dehumidifier running in the basemen.
After yesterday pouring rain (~80F), we did not see any wetness but the
dehumidifier was showing 72% RH and seems like the owner set the target to
60% RH. and it has a pipe to drain the water to outside.
Is this humidity normal? I heard anything beyond 60% RH is getting into
dangerous zone of growing mold?
Thanks a lot! |

n*******e 发帖数: 55 | 13 Thanks a lot, gezhi89. 60% RH at 80F does seems high comparing to yours,

need to check again about the humidity reading then. Thanks. |

C*******d 发帖数: 15836 | 14 Basement is usually colder than above ground, thus more condensed water and
higher humidity level than above ground. Also, it has more chance to have
leakage from outside environment from cracks etc. In addition, the
ventilation in the basement is usually not as good so the water in the air
can not be easily taken out. So it is more likely to have mold in the
basement before it affects the above ground building, and it is less likely
to be detected because usually people don't use basement as mu |

So if you outside temp is between 60 to 80 in a day (if live north), you may

Surprisingly statistics from both NOAA , and Cityrating.com show that Los
Angeles has, on average, a slightly higher relative humidity than, say,
Albany, New York. It is hard to believe because the air in L.A. does not
have that hot, sticky feeling that air in east coast cities has. Perhaps
this phenomenon is because the air in Los Angeles usually comes off the
ocean and is cool compared to air over land masses where the sun has had
time to warm it. Until I resear... 阅读全帖 |

From Wikipedia, the free encyclopedia
HVAC (Heating, Ventilation, and Air Conditioning) refers to technology
ofindoor or automotive environmental comfort. HVAC system design is a major
subdiscipline of mechanical engineering, based on the principles of
thermodynamics, fluid mechanics, and heat transfer. Refrigeration is
sometimes added to the field's abbreviation as HVAC&R or HVACR, or
ventilating is dropped as in HACR (such as the designation of HACR-rated

Yes, or you can safely leave it burning. The pilot helps keep the moisture
from inside the firebox, which is caused from the humidity in the air. It
also will extend the life of the thermopile and thermocouple when the pilot
