VEU Approved Exhaust draft stoppers, also known as vent draft stoppers, are devices used to prevent cold air from entering through the exhaust duct of a home's heating or cooling system. Their effectiveness depends on the specific design of the draft stopper and the exhaust system that is installed in your home. Some exhaust fans cannot move sufficient air when they are restricted with air flow from a closed door.
If properly installed, an exhaust draft stopper can prevent drafts and improve energy efficiency by keeping cold air out of the duct system. This can lead to lower energy bills and reduce the workload for the heating or cooling system.
However, it is important to note that exhaust draft stoppers may need to be removed periodically for cleaning and maintenance to ensure the system is working efficiently. Also, some models may require careful installation to prevent damage or improper sealing, which could lead to leaks or even damage to the heating or cooling system.
Overall, exhaust draft stoppers can be an effective solution for reducing drafts and improving energy efficiency in homes. As with any product, it is best to research and choose a reliable and high-quality draft stopper that is compatible with your specific heating or cooling system.

Thanks for all the videos I have made huge improvements to my 1970s home one suburb from your office. Door seal works great. I will say that I used an inline fan to also get rid of the noise of the fan inside my house as welll.
Thanks so much for the feedback. It’s feedback like this that drives us to make more, 😉
It doesn’t make any sense to me to have exhaust fans/range hoods going into the ceiling area. They should be ducted to the airside air!! And of course, they should always have draft stoppers. Makes so much sense!
Great video!
Shower with the bath room door open. This raises the humidity throughout the home.
Most homes have low humidity in the winter.
If your exhaust system can move enough air it will not. If the in your home is warm, the high humidity air you move from your shower is less likely to condense inside your well ventilated roof.
It raises humidity in the bathroom with the door shut, and the exhaust fan doesn’t work very well at all.
It’ll work a lot better with the door open. If the fan is performing well/adequate, humidity shouldn’t increase in other rooms.
Excellent video. Thanks
Is there any solution for an IXL heat lamp & exhaust vent. I have one but it's too big for the draft stopper
They do a solid job of working to stop me sleeping as they bang open and shut in the wind. On brand new standard builder Clipsal CEF40 installed in 2020 🤣 they cost over $100 and somehow they can’t do any basic engineering.
They tend to open a little too easily.
If it's air tight (energy efficient) home if you are sucking air using exhaust it should pull air from somewhere and that will be hard for an air tight house.
Excellent observation! Most homes aren’t very air tight though, and windows can tend to leak. In the future, a balanced heat recovery ventilation system is going to be the only way to exhaust our bathrooms.
What do you have for inline then please?
I am not sure how related or unrelated this is but do you have any thoughts on range hood systems in air tight buildings like Passive house 0.6ach. Should we recirculate or have a make up air system. As a Passive house designer this is by far the biggest issue I face with air tight homes in australia.
Ideally, a dedicated makeup air supply with integrated motorized damper control by the rangehood. Having said that, it is heavily depended upon the cooking style of the occupants. Personally, if I have a reticulating range hood, I will need to wash the filter weekly.😢
@@josephcheung8311 one of the biggest challenge is being in Australia and the absolute lack of knowledge about all this stuff. I originally designed a recirculating system with a plasma filter inline but I really don't like the idea of that. I think this would make for a very interesting video if you are looking for ideas haha. It would solve alot of problems for a lot of people
What is the tight huse heat shield product?

is it possible to combine a dfart stopper with ducting to the eave?
Of course, use an inline fan! We have all the products on our our store. HTTPS://tighthouse.com.au
@@ecoevohow would you convert an existing 300mm ceiling exhaust to include a th draft stopper and be vented externally? Some kind of 300 - 150mm reducer?
What's the main issue with venting the exhaust fan into the ceiling space?
Pushing high humidity air into a cold roof, increases your risk of mould growing inside your roof.
@@ecoevo Is this as likely in an old tiled roof?
It is more likely with a colourbond roof, but never the less, it is still not ideal even with a tiled roof. Tiled roofs also get very cold, but that do have more air flow.
Just open the window....
Just locate the window and fan better
