Building science has come a long way since the early days of basement and crawl space technology. In the old days, homes were designed with an open or vented crawl space. In reading about requirements on your site, it sounds like we need to include a venting system. To put a vent at floor level seems like it would allow the warmer air from the rest of the basement (there is a wood stove that will be used for heating the house) enter the cool room. A: The vents should be to the outside, not within the basement space.
We don’t really have enough money to keep calling plumbers out for them to tell us its the sump pump. However, when we open the lid of the sump pump there is definitely a smell coming from it. (it hasn’t run since the summer by itself) But I don’t think its the same smell that we smell coming from the vents and in the basement. Closing air vents in a room in your home that’s seldom used during the winter in most cases will not save energy. This is surprising news for many people who may close off the forced-air heating vents to an unused spare bedroom, bathroom or storage area during the winter months in Edwardsville, Glen Carbon, and other parts of Metro East Illinois. Insulating a basement properly is rather challenging in cold climates. In this article I’d like to discuss how to insulate basement walls in cold climates. Insulating basement walls in cold climates is a great way to keep your home warmer and drier. However, special care should be used when insulating concrete (or block masonry) basement walls.
I have been a master plumber for 45 years, and I have ran into this problem before. Not every time, but most times, it is a vent pipe in the attic that has come apart. When you have an open vent pipe, the only place that the odor can go to is inside the house. Some times it comes apart inside the wall, but most times it is in the attic. It is necessary to allow the pressure in the drainpipes to equalize as wastewater flows through them. Without this vent, sinks, tubs, and toilets would gurgle, and in some cases, the toilets and drains would act like they were plugged. These plumbing vents can freeze closed during prolonged cold periods or get clogged with leaves or other debris. Why Is My Fireplace Smelly. Smelly Fireplaces Spell Trouble by Dave Lamb – [email protected] Many people complain about an odor that comes from their chimneys even when a fire is not burning or has not been for a long period of time. The tutorial "Installing a Range Hood - Roof Vent", offers instructions for the other option. Choosing the proper range hood is simple. The CFM rating for your hood (cubic feet per minute, or the amount of air that a fan is capable of moving in a minute) should be approximately equal to twice the square footage of your kitchen.
HVAC is not my trade so please forgive an elementary question. I have just purchased a two story house and I would really like to close the vents upstairs and heat from the bottom up with the downstairs vents open. Also, cool from the top down in the summer.

The minimum area for each vent is 100 square inches (10 x 10 inches). If it has a grille, its net free area is roughly 50 per-cent of the total area. This means the vent should be 200 square inches (10 x 20 inches). If the opening is louvered, the free area is even less, only about 25 percent. Heating & Air conditioning guys have sensors that measure it. It's generally about $50 to have one of them come out and spend an hour running around your house like a goon making tiny adjustments to your vents and waving little handheld sensors all over the place. The process is called "balancing" the vents.
For example on a 1 1/2″ sink drain the vent can not be located more than 5ft away from the trap and the pipe between the trap and the vent can not have bends in excess of 135 degrees. The rules for siphonic fixtures such as a toilet differ. You can have the vent 10ft away and have 225 degrees before the vent. No, you do not need vents if you encapsulate your crawl space. The bottom line is if you install the high-performance vapor retarders correctly, you can forget about your vents. I don't care if you keep them open or closed, it will make little difference. The proof of concept of this method of encapsulation is widespread. Look for what you can see, handles or knobs on the exterior of ducts which you can rotate from the outside.
