发帖数: 4125 | 1 It does not matter that much.
The main reason the cold pipe (bigger one) is insulated is because if it is
not water will condensate on it and drip down on to area should not get wet
and cause other problems.
If possible you can wrap them both together, use the cold pipe to help cool
down the hot pipe part of the way.
If you system is very efficient, the cold return pipe should be just a few
degree cooler than the room temp. Most over sized system is not, and the
pipe is much colder than the air. |

发帖数: 14763 | 2 I'm pretty sure that's a whole-house vent, because I have a similar one.
I built a box with foam boards, and cover the vent for summer and winter.
Alternatively, you can seal the vent with film and tape.
If that big vent is not sealed, what could happen is, the harder your fan
works, the more air it sucks from the upper floor. Once the warm air into
the colder attic, the vapor in it condenses quickly and increases the
humidify in attic. |

发帖数: 14763 | 3 Sounds like we need to go back to the principles.
Ice dam forms when the roof temperature is uneven. Say, insulation is not
enough, and the warm room air escapes to the attic or the attic is heated by
other leaks. Since the warm air always go up , the upper part of the roof
is warmer than the lower part. So, the snow on the upper part would melt and
refreeze when it reaches the colder lower part.
Again, the two killer factors, insulation and ventilation. Good insulation (
and air seal) prevents ... 阅读全帖 |

发帖数: 14763 | 5 Purportedly, the colder fresh air comes in through soffit, warming up and
rising to the upper attic space, and go out of garble or ridge vent, taking
out extra heat and cooling down the roof.
So, soffit vent is a must. And in case you have an exhaust fan, the soffit
vent size must match the cpm so that it doesn't become the bottleneck in the
air path. |

发帖数: 14763 | 6 Yes, and it's desirable in case of colder climate. Otherwise, the snow on
the upper part will thwart, flow down and freeze again at the eaves, forming
the horrible ice dam. |

Why is the suicide rate high in seattle?
Best Answer - Chosen by Asker
It's called Seasonal Affective Disorder (S.A.D). One theory is that cold
weather causes serotonin deficiencies which result in depression. Suicide
rates are also higher in colder countries (like Scandinavia) than developing
countries, which are often warmer, even though life is often "harder" in
developing countries. |

rooms. But in terms operating cost in the long term. mini-splits would be
cheaper. Though you have 8 rooms, I doubt all 8 would be used at the same
time. especially at night. If only 3 rooms are used, min-dsplit allows you
to only turn on only those, saving you energy bills. furthermore, with
central AC, almost 30% of the energy is wasted while travelling thru

1. Open space concept. Smaller rooms downsize the heating to a more

3. Whole-house fan. Cooling down the house fast, even in winter :)
4. Range vent. Even you shut it off, it's still a big leak through your
otherwise well-insulated castle.
5. Bay window. It sticks out of surface, and thus more vulnerable to winds.

and Jan are pretty much the same in the two cities but chicago has a warmer

difference is that chicago weather is more variable because it's west of
the lake michigan while toronto is north-west of lake ontario but has lake
