DR21 air vents DR21, 12 W, Black

Product Information

ii. The amount of air required depends on the size and efficiency of the appliance. Generally open fires need far more air than a stove. However, we have a problem with them. The external vent cover is quite flimsy plastic and rattles like mad at the slightest breeze. This is quite annoying since the house is otherwise quiet, especially the one in our ensuite bathroom. It also means that we routinely have a cold draft coming in to each room with an extractor. However, while something like this will be quite easy on the downstairs vents, it will be a real problem upstairs since they are beyond the reach of my extension ladder (25ft+) and there are no nearby windows for easier access. Smaller items will be delivered using Royal Mail 48. Larger items will be delivered by Fedex or ParcelForce. We offer three installation kits. These are aimed at professional installers, or at homeowners who are confident of their DIY skills.

If you’ve already got a standard vent fitted – there’s already a hole drilled through the wall for airflow. This makes things really easy.It cannot be used on a kitchen extractor fan and the fat in the air will rapidly clog the interior. Replacing underfloor air vents which will stop a draught blowing under your floor, while allowing enough air for the vital ventilation.

These magnets are incredibly strong for their size. They are dangerous if ingested or inhaled so make sure they are out of reach of children and pets. v. Combustion air can either be fed into the stove with a direct air kit through a ducting to outside or by taking air from the room. If the air is taken from the room then an air vent must be installed in the room in which the appliance is situated. This does affect young children and there some research that it can be one of the causes of childhood asthma." Presumably by having 6inch wide holes that cannot be properly shut in so many rooms of our house, making it draughty, we run the risk of childhood TB and rheumatism and constant chest infections? The unique DR21 vent is the solution ? this new product allows only the air that is needed to enter your room. Even a high wind or forced air won?t be a problem as shown in the video. At ?29.99 our unique patented vent will pay for itself in no time, as you won?t need to try harder to heat a draughty room.I had thought of simply putting some tape over the vents on the outside, just to seal them shut. Since we have a pebbledash render on the walls, it seemed easier, and maybe more effective, than fitting a cowl like this: The solid tubing kit contains a DR21 air vent, an interior vent cover and a piece of solid tubing to go through the wall. Use this kit when you intend to use a 4" core drill to drill a straight hole through a wall.

The DR21 acts as a like for like swap – you fit it onto the outside wall in place of the existing vent. There’s no fancy mechanism or any moving parts that could get damaged. Just an incredibly clever design that causes the air to move in a zig zag pattern, slowing the rate of air flow down when the demand for oxygen is low, instantly reducing those terribly cold air leaks. Since no-one's said that you can't just tape the external vents shut, I'm going to give this a go. Depending on the effect this has on the draft, I may try putting some insulation inside the vent sleeve to help with this. Then I can happily use the windows for my ventilation, knowing that when I want a warm room, I can achieve it and when I want ventilation and air circulation it is completely within my control. Your all need some good external grade glue, epoxy resin or something that will remain in place in low and high temperatures. Internal Super Glue will probably fail in winter temperatures.

A relative of mine converted an old house into flats and put bathrooms in some basements. This room had the required plastic lining, with concrete shell inside, lined with plaster. For reasons too peculiar to go into, the owner of this flat refused to open her window, (there was no extractor fitted, since the conversion predated these being mandated) for SEVEN years, meaning that the room was basically sealed for that whole time. After that period the room DID become damp and the plaster developed mould. The DR21 air vent cover has pending patent and has been independently tested by BRE, has HETAS approval and is produced to ISO 9001:2015 standards. It is made of high quality thermoplastic and has been designed by a stove fitting expert. It is also entirely manufactured and produced in the UK following strict manufacturing guidelines. You can be rest assured you’re receiving one of the safest and most effective air vent covers on the market.

Do you think I could tape up the vents upstairs by taking the inside cover (including fan) off, reaching through and applying tape from the inside? DR21 Ltd is a family business, run out of my home-town of Knutsford, Cheshire. We’re a small company, but our product is made entirely in England and is manufactured ISO 9001:2015 standards. It was independently tested on the 24th October 2016 by BRE, one of the major facilities in the UK, and subsequently approved by HETAS. We have a 60-day return policy, which means you have 60 days after receiving your item to return it. Most vents become a source of cold air and draughts are created as the fire draws the air from the vent. According to research over recent years, childhood asthma is caused by too much ventilation, too little ventilation, too much cleaning/dusting and too little cleaning/dusting. I'd take all of it with a big pinch of salt. And I say this as someone who developed asthma as a child.If you’re about to have a wood burning stove or other appliance fitted then it’s very likely the installer will need to drill a hole through the wall behind the stove to ensure the product has sufficient ventilation. In this case simply provide them with the DR21 and request that they fit this instead of a louvered vent, they will be able to do this for you no problem! The DR21 air vent is affordable enough to form part of any standard quote and its draft reducing qualities and modern look can be used to upsell customers to a higher-powered stove than they might otherwise have bought. I think this is the risk which extractor vents are designed to mitigate. I'm desperately trying not to use the phrase "nanny state" about this, but it's hard work.
