Thanks! For peace of mind, consider buying a hydrometer to measure your indoor relative humidity, which will cost you maybe $20 to $30 at most hardware stores. Depending on the quality of the machine you buy, you can expect to recoup anywhere from 50% of the heat in the air, to as much as 95%. Hi Barb, an HRV or ERV would likely help with dust, make sure to install the right filter, see this page here - Choosing the right home air filters. I have a brand new home, moved into in June. I would also assume you may have a somewhat older home as new homes now would likely be required to have ventilation equipment to meet regional building codes. Then I want to lay down some nicebeach stones or gravel to ensure the area is dry. The air pressure in the house needs to equalize, pushing the air out of cracks and holes, minimizing efficiency (source). The folly of this was quickly realized, and vapour barriers became a part of the building envelope shortly thereafter. Additionally, ERV systemsallow for maintaining the ideal relative humidity of 40% to 50% in indoor home environments. If your return air ducts are on the ceiling, moving a duct to the floor will eliminate the problem. A basement also tends to accumulate chemicals in the air as well as gasses such as radon. As a healthy living enthusiast, I have come to realize that 2 areas that are overlooked in the pursuit of good health are the quality of the air we breathe and the water we drink. I change the furnacefilters every 3 months. where would the best place be to put it..?

Hi Michael, you might as well shut if off if you have crossflow of air anyway. It's tough to trouble shoot from a distance, but I can offer a couple of suggested sources you may want to check. Does your basement have that smell? As homes began to be insulated, they were still not airtight. Also, how worried do I need to be that mold might have gotten inside the walls of my house? Radiant heating systems in homes dont introduce any fresh air, so you should have some sort of ventilation system to remove airborne contaminants and humidity, while providing fresh air for occupants. An air-to-air exchange system works by taking two air streams of different temperatures, brings them into thermal contact, and transfers or exchanges the heat from the inside air leaving the house to the cold outside air coming in (source).if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[468,60],'airandwaterexpert_com-leader-3','ezslot_8',117,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-airandwaterexpert_com-leader-3-0')}; During the hotter seasons, when cool air is preferable, the heat exchanger will cool the outdoor air coming in. You absolutely need an air return in the basement. Humidifiers, dehumidifiers and air purifiers are available to deal with some of these issues. Fresh air from outside will keep the inside air cleaner by filtering out pollutants from inside the home.. They work in tandem, where one unit blows out at the same time that another unit blows in, each has its own ceramic heater core that absorbs and releases heat. Thanks. There are a couple of companies that manufacturer ERV wall insert ventilation systems that only require running a low voltage wire to each unit. . As I am in NB, no sense in giving you the name of the installer I had. I use a wall control. 
There are a few types of air exchangers, and all move air differently through the system.

The air will always use the path of least resistance, so instead of drawing air from upstairs, it draws it through the HRV and therefore from outside. Can we stop doing this once we install an HRV? On the down side, there have been cases where people have spoken about debris or mold buildup inside the tubes, and that can be difficult to deal with. Do you mean you have hot water radiant heating in your floor and you are asking if you should install an HRV or ERV ventilation system? That might help you find out how long the moisture is sticking around, and how long after a shower you should run your fan. Somewhere in the range of 35 to 50% relative humidity is generally assumed to be the best for avoiding most health risks and irritants. Regards, Mike. There's a couple of ideas, hope it helps. If your home randomly fills with smoke I would look for other sources of depressurization, could it be when someone turns on a bathroom ventilation fan or stove hood? And you will certainly save money overall, as heating moist air eats up a lot of energy. This process saves the homeowner money as it reduces the strain on the air conditioning system (source). With a fresh air appliance, your basement can keep the good air while kicking the bad air to the curb. At the same time, exhaust and intake fans are an option but are not as effective. What we write in these pages is meant to inspire ideas and solutions, not fear and anxiety. ps. 
Properly sealed homes require mechanical ventilation systems to remove moisture and provide sufficient fresh air for occupants. When you say your basement is constructed as I described, and you've checked all other sources, I would think the way the basement walls are builtis starting to look like the more likely culprit. Another suggestion I would make is perhaps installing a direct air feed to your woodstove. You may also need HRV maintenance, if the core is plugged up with debris it may throw off the balance by ejecting more air than a plugged filter allows in. However, they are less efficient than the counter-flow models rating around 70%. Best of luck, we hope you can resolve this and regain your health. Additionally, excess moisture also causes wood to rot. If you have that much moisture I would think about a dehumidifier maybe, and with any double pane window you are bound to get humidity on the really days anyway. This is when we noticed the back drafting and that the house definitely had negative air pressure. If the return ducts are left unsealed, there will be suction on the whole house. Cross-flow heat exchangers are smaller, and some can fit in a window. Circulating the air in your basement is imperative to having a healthy home. You may cause a backdraft to the chimney. Place the vent where it will draw air from the next room (source). Several sources recommended to install HRV near there it terminates externally, which mean outside wall. Plan on spending around $2,000 installed, that'sfor a reasonably efficient one. 
A cross-flow air exchanger has the two air streams going in a perpendicular motion., Whether you choose a cross-flow air-to-air exchanger or a counter-flow air-to-air exchanger depends solely on your needs.. It exchanges the energy of stale indoor air and uses it to either warm or cool the outdoor air entering the house. If your HRV exhaust pulls air from the bathroom that's one thing, but if it is a fan vented directly outside then opening a window is still a good idea. There is a green color on the outside cement wall along the grass line. I would start with a little fan testing forensics and see if that is what iscausingit.

I spent a year researching HRV/ERV and what I found was HRV is the better choice overall. As for making that a basement window, you may be just as well to have that an upstairs window, depending on the air quality in the basement, meaning if it is musty (as many are) or if it has elevated levels of radon gas, in which case, an groundfloor window may be preferrable to open I think. Having an air-to-air exchange system that introduces fresh air into the basement and draws out the polluted air is essential to your health.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'airandwaterexpert_com-leader-4','ezslot_10',118,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-airandwaterexpert_com-leader-4-0')}; Although there are more than two types of air exchangers, a house will generally use either a counter-flow air exchanger or a cross-flow air exchanger. basements Since your fresh air vents are best located in living areas and bedrooms, you might find that its well worth the added cost of solid ducts simply for noise reduction. ventilation flowair ductless mechanical I feel and fear there is massive cold air coming in constantly. All the above, no matter how tightly sealed, eventually leak their harmful chemicals into the air. Fran Perks, Rockland, Ontario. The air will always use the path of least resistance, so instead of drawing air from upstairs, it draws it through the HRV and therefore from outside. Can we stop doing this once we install an HRV? On the down side, there have been cases where people have spoken about debris or mold buildup inside the tubes, and that can be difficult to deal with. Do you mean you have hot water radiant heating in your floor and you are asking if you should install an HRV or ERV ventilation system? That might help you find out how long the moisture is sticking around, and how long after a shower you should run your fan. Somewhere in the range of 35 to 50% relative humidity is generally assumed to be the best for avoiding most health risks and irritants. Regards, Mike. There's a couple of ideas, hope it helps. If your home randomly fills with smoke I would look for other sources of depressurization, could it be when someone turns on a bathroom ventilation fan or stove hood? And you will certainly save money overall, as heating moist air eats up a lot of energy. This process saves the homeowner money as it reduces the strain on the air conditioning system (source). With a fresh air appliance, your basement can keep the good air while kicking the bad air to the curb. At the same time, exhaust and intake fans are an option but are not as effective. What we write in these pages is meant to inspire ideas and solutions, not fear and anxiety. ps.

Properly sealed homes require mechanical ventilation systems to remove moisture and provide sufficient fresh air for occupants. When you say your basement is constructed as I described, and you've checked all other sources, I would think the way the basement walls are builtis starting to look like the more likely culprit. Another suggestion I would make is perhaps installing a direct air feed to your woodstove. You may also need HRV maintenance, if the core is plugged up with debris it may throw off the balance by ejecting more air than a plugged filter allows in. However, they are less efficient than the counter-flow models rating around 70%. Best of luck, we hope you can resolve this and regain your health. Additionally, excess moisture also causes wood to rot. If you have that much moisture I would think about a dehumidifier maybe, and with any double pane window you are bound to get humidity on the really days anyway. This is when we noticed the back drafting and that the house definitely had negative air pressure. If the return ducts are left unsealed, there will be suction on the whole house. Cross-flow heat exchangers are smaller, and some can fit in a window. Circulating the air in your basement is imperative to having a healthy home. You may cause a backdraft to the chimney. Place the vent where it will draw air from the next room (source). Several sources recommended to install HRV near there it terminates externally, which mean outside wall. Plan on spending around $2,000 installed, that'sfor a reasonably efficient one. A cross-flow air exchanger has the two air streams going in a perpendicular motion., Whether you choose a cross-flow air-to-air exchanger or a counter-flow air-to-air exchanger depends solely on your needs.. It exchanges the energy of stale indoor air and uses it to either warm or cool the outdoor air entering the house. If your HRV exhaust pulls air from the bathroom that's one thing, but if it is a fan vented directly outside then opening a window is still a good idea. There is a green color on the outside cement wall along the grass line. I would start with a little fan testing forensics and see if that is what iscausingit. There are no heating coils, you are simply operating fans, so they are relatively cheap to run. Hi, My home is 10 years old, we always have moisture on our window's, this year I put plastic on all windows with the exception of the kitchen and the patio door. In the last couple years started noticing more dust which was there before. twistfix recovery heat An air-to-air heat exchanger is a mechanical ventilation system and an important part of a homes heating, ventilation, and air conditioning system (HVAC). AHeat recovery ventilation system is pretty much always a good idea for a home unless it is very old and extremely leaky and getting enough fresh air from lack of an air barrier. Hi I recently brought a flat which sound travelling between, I am in the second floor since then I have experience moulding and condasetion what your advice to tackle this issue, your help will be much appreciated thanks. They can freeze or seize shut. I continue to beleive that my HRV is "leaking in" massive quantities of cold air when it's not working and would like to be proven otherwise.
