On the vents closest to the main unit it should read around the same temperature that the thermostat is set to after its been running and then as the venting increases the temperature should be less, between 2 to 10 degrees different depending on how well the ducting is in the attic........
It all depends on the size of the house, how well it is insulated, the outside temperature, and the inside temperature. For most houses about 20 kW should be enough (say 75,000 BTU/hour)
Vents in the volcano are passage ways for the magma, steam, and heat to escape the earth.
it sounds like you have two problems the cailabration on your thermostat is a little bit off making it run a few degrees longer and on hot days its not getting cool enough in the house because your evaporator coils in side the indoor unit is clogged and are not letting enough air get by to cool the heat load of the house you probaly have noticed a difference in how hard the air blows out of some of the vents.
Natural
The flow of heat in and out of an object changes its temperature.
the temperature mat should be around 76 c unless if it is new to the house, that temperature should be 76c.
Likely, your blower (fan) is out.
You dig hole in living room floor and wait for magma to come out. Then house is br00tally warm.
thomas hunt said that yes if does keep all of the heat in
None. Any paint will gass off in to compounds. You will breath these comounds. They are all toxic, and carcinogenic,
Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.
Yes, especially if you live in an area where the humidity is higher. The vents allow moisture in the air to escape from under your house. Moisture trapped under your house can cause mold and floor rot. The vents should always be open a little. This is to ensure you don't get a sick home and so the air circulates through the house. That's if these are hvac vents. If the vents go to the outside, they should always be closed.
the heat blows out the defrost when it should blow out floor vents only
The temperature you want your house to be.
Heating vents should be placed near or on the floor in a room because heat travels up not down.
Vents should be situated near windows. Windows that are north or west facing should get a vent before a south or east facing window would get one. (Assuming that the vents also supply heat.)
There are heater doors on the heat blower box that direct the path of the heat. Apparently the heater door to the floor vents is stuck closed.
