Report telling consumers the risks of radon, how radon gets into a home, and steps consumers can take to reduce radon exposure in their homes. Website with information about radon-resistant construction techniques and other radon resources for builders, contractors and homebuyers. Book presenting the best techniques for energy and resource efficient residential construction in the colder climates of North America. Basement slabs and slabs on grade should be air-sealed to the extent possible to block radon entry into the building. Radon and other soil gases can create an unhealthy indoor environment if they accumulate inside the home.
It is the CFM at an identified density other than .075 lb/ft3. It is also the required mass flow rate divided by the density of the gas being handled. Since fans and blowers handle the same volume of air regardless of density, the ACFM value is the preferred value to use when selecting a fan or blower. Note that ACFM and SCFM are not interchangeable except at .075 lb/ft3 density. The Auto-Draft will continue to efficiently produce draft in your wood stove as long as the following maintenance is performed at suggested intervals. Depending upon the type of wood burned, the fan must be removed from the vent pipe and cleaned at least once per year. Soot and creosote build up must be removed from both the fan wheel and housing. The fan motor is permanently sealed and requires no oiling.
Exterior radon system neatly installed through each deck of this Chicago apartment building and exhausts above the roof. This home’s Home Owner’s Association wanted the system to be located on the backside of the home. We were very creative in our solution to meet the HOA’s requirements. This is a picture of the exterior exhaust with the fan underneath the deck and exhaust running along the downspout on the rear of the house. This photo shows the radon fan installed underneath a deck. The exhaust pipe has three supports that will provide superior wind durability even with severe storms that produce winds above 70 mph. 50/50 Four Pipe System unit with two equally sized heat exchangers, 50% system redundancy is provided during peak the heating and cooling seasons.

Before you buy a kitchen exhaust fan, it’s always a good idea to get the written installation instructions from the manufacturer. These documents will often contain sizing guidelines as well as detailed step-by-step methods the manufacturer wants you to follow to keep the warranty in force. You’re really observant to recognize that large kitchen exhaust fans like these have a voracious appetite for air. You need to replace every cubic foot of air the fan pushes to the outside. Grease can and does coat the surfaces of your kitchen if they’re not vacuumed and exhausted to the exterior of your home. Sooner or later even with a great exhaust fan, you can still develop a fine coating of grease on light fixtures, cabinets, walls, and ceilings. Every time there was a power failure, about 2 times a week in Florida, all of the units would require a manual reset.
Hansa engineers came up with the Vertical Mounting Kit that can be adapted to any kind of stove door front and attached to the stove fan using a couple of the three screw holes in the base described before. This way owners of the built in stoves can use the Sirocco Plus fan to get the heat distributed evenly around the room. All in all, The Sirocco Plus stove fan is nothing more than an original Sirocco fan plus the VMK. If you want to warm up a standard room with a stove that won’t reach temperatures above 350°c, then you need to consider stove fans like Valiant Premium, Ventum 3 or Phoenix. If you’re not sure what maximum temperatures your stove can reach, then you are better off buying a stove thermometer. It is an inexpensive device that not only helps to protect your fan, but also gives you a better understanding of the best operating temperatures of your stove. The Valiant stove fans are powerful, yet silent, reliable and covered by a 2 year warranty.
Sand the area around the indentation to remove any chemicals that may be vaporized while you smoke. When you’re ready to smoke, place your material on the indentation, cover the large hole with your finger, and inhale through the mouth of the can to fill it with smoke. Remember that heating aluminum to high temperatures is linked with serious health risks, so it would be safer to build a pipe out of other easily available household items, like an apple or a potato. Condition the pipe by heating the smoking area and the adjacent area of the can. While there’s no scientific evidence to back this claim, the general idea is that this will vaporize chemicals used to coat the interior of the can before you light up. You can also sand the paint off the indention and the adjacent area. The belief is that this removes a large part of the potentially harmful material that might be vaporized as you smoke.

A radon vent fan should be installed in the ventilation pipe if testing indicates radon concentrations are greater than the EPA’s action level of four picoCuries per liter (4 pCi/L). Radon fan (i.e., an active system) OR an electrical receptacle installed in an accessible attic location near the radon vent pipe (i.e., a passive system) to facilitate future fan installation if needed. A space surrounding the radon pipe, having a vertical height of not less than 48 inches and a diameter of not less than 21 inches, shall be provided in the attic area where the radon fan can be installed, if required. So I’ve installed metal duct from my bathroom exhaust fan to the gooseneck vent on my roof. We have a train that comes close to our house and when the fan isn’t running and the train blows it’s whistle the sound reverberates down the pipe into the house. Do you have any solutions for dampening noise that comes through the pipe into our home. They took their fantastically popular Premium 4 stove top fan, removed the base which would have stood on the stove top and replaced it with a magnetic attachment they call ‘wings’. Broan-NuTone™ exhaust ventilation fans allow your home to exhale, eliminating humidity, odor and airborne particulates from your bathrooms, closets, mud room, laundry, work out space and more. Ventilation fans improve indoor air quality by venting moist air quickly outside, which helps to control mold and mildew growth.
Induced draft systems are much more complex than forced draft, especially if several ASPs are feeding the biofilter, which can have its own set of complications. As an example, the authors designed an aeration system for Chesapeake Compost in Baltimore, Maryland that is located inside a repurposed industrial building. The facility has 7 ASPs on each side of the main operating floor for a total of 14 blowers feeding a biofilter. The ductwork had to be run from one bank of blowers above the operating floor to connect with the blowers on the other side and from there to the biofilter. The effectiveness of aerated static pile composting depends largely on the aeration system, which can comprise a large portion of the facility’s cost and energy use. With an ASP, the operator relies entirely on the aeration system to get air into the pile and make the composting process work by supplying oxygen and removing heat, moisture and odors. Many design considerations go into developing an aeration system, and while an engineer usually handles the calculations and design work, it helps to know what goes into it.
It also makes it possible to add multiple ceiling vents and connect them to the same fan to provide additional ventilation to a larger bathroom. Since ceiling fans are located directly above the bathroom, users may notice more noise and vibration than they would from an in-line fan. The moist air that’s belched out by the fan can be sucked right up into the open soffit vents and be drawn into your attic. Before installing a low wattage fan you should drill a small test hole (5/16″ or 1/4″) through the slab at the farthest distance from the suction hole and measure the sub-slab negative pressure under the slab. If you have greater than 5 pascals (0.020″) negative pressure under the slab you should be able to install a 20 watt fan without significant change to the radon reduction. The 20 watt fans will easily pay for cost of the fan in electrical savings in several years. In this case, multiply your bathroom’s length by its width to determine its square footage, and multiply it by 1.1.
The output from an FCU can be established by looking at the temperature of the air entering the unit and the temperature of the air leaving the unit, coupled with the volume of air being moved through the unit. This is a simplistic statement, and there is further reading on sensible heat ratios and the specific heat capacity of air, both of which have an effect on thermal performance. People often notice water dripping from the fan cover and think they have a roof leak. More often than not, the issue is water flowing back down the pipe into the fan. For this reason, you have to use the right pipe, and it needs to be installed so water never leaves the pipe if it forms on the inside pipe walls. Once you get the fan, stop and read the installation instructions.
Fill it with enough water so that the stem of the mouthpiece is slightly submerged. Tape both cans together to create the full chamber of the water pipe. If you’ve got something to smoke and nothing to smoke it out of but some soda cans, you’re in luck. It’s easy to make a basic pipe or a more elaborate water-pipe to smoke form. Bathroom vent ducts must always terminate on the outside of the house. Here’s the interior exit point where the duct terminates the vent hood. Take steps to properly support your pipe run either from below, with blocking or from above, with plumbing strap or large, heavy-duty cable ties .
Only total pressure in ductwork always drops in the direction of flow. A theoretical and practical guide to the basics of designing air flow systems. The fan’s performance can be affected by a few other factors specific to the individual heating appliance surroundings, like the depth and shape of the recess, the height of an aperture etc. So, use your fan’s top handle to move it around the top plate of your stove to determine the right position for the best performance – just make sure you keep the fan away from the flue and never in front of it. If you decide to go for any of the SmartFans make sure you get yourself familiar with the illustration below as their positioning rules are slightly different. Because the unit doesn’t hook up to a duct, the product description doesn’t include how much noise it produces but keep in mind that it’s not a silent unit. Another important thing to know about this fan is that it’s Energy Star-certified for efficient operation and is UL-listed for damp environments . Some reviewers did mention that the fan is a little larger than expected, but that it wasn’t necessarily a dealbreaker.
A properly vented bathroom shower fan will remove moisture and decrease the humidity in your house. Some folks ask if it’s okay to vent moist shower air into a roof soffit or unheated attic. Others ask whether they should be concerned about their current “mile-long” plastic duct tubing. The market is flooded with extremely cheap stove fans, as with every other product, you can always find some flimsy copies of the quality merchandise. We cannot recommend them as we only test the above fans and we always pack in a top notch customer service; check out the reviews from our verified customers. The SFR stove thermometer can be placed next to your fan or on the flue pipe as it comes with a screw and wire to secure mounting. This gives you the comfort of knowing how hot your stove is and that your fan is safe from damage. As of today – November 2017 – the Sirocco Plus is the only stove fan that can be adapted to work on the built in stove.
