DR21 air vents DR21, 12 W, Black

Product Information

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! Hi, You said it would take 15 minutes to fit, and I did it in 7. And the effects were immediate!” B.T. Cardiff. If you already have a stove which is over 5kw installed it should, by law, have an air vent. It will not work efficiently without one as it will be struggling for air. 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. 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?

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.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.

The hole is 100mm, and yet the free air equivalent is 3400 sq mm. This is because the air vent sits on the outside of the wall, and does not reduce the size of the hole through the wall. 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? One of the best parts about this air vent cover is that if you do decide to light your stove, air is pulled through at a faster rate – in fact it’s pulled through at the exact rate to meet the demands of the appliance – meaning everything works just as it should. How does the DR21 vent cover work?

Smaller items will be delivered using Royal Mail 48. Larger items will be delivered by Fedex or ParcelForce. We get a lot of customers complaining about the draught that comes through air vents. The air vent is there to provide enough oxygen for your appliances when they are burning fuel. If they don’t get enough oxygen they produce carbon monoxide which is a killer. So the air vent is pretty useful when you’ve got a fire lit. But what about all the rest of the time, when the fire isn’t lit and there’s still a howling gale blowing through? Wouldn’t it be great to have something that restricted the air flow and prevented those annoying draughts? Ta daaa! We introduce the DR21, invented by David Gattie, a stove fitter with customers putting just such a complaint to him on a regular basis. iv. It would be harmful to burn the oxygen from a room without replacing it with fresh air from outside.

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.

Working Capital

Have none of you people heard of windows? Windows are natural ventilation and have the added advantage of not using extra electricity. So far as I can tell, my 70 year old house has survived the first 69 years of its life without extractor vents, probably because its owners understood about windows. I am fully aware of the problems of humidity, I just don't need some idiotic and expensive ventilation system treating me like an idiot and making a noise in my ensuite bathroom, when it's right next to a perfectly serviceable window. If I wanted that, I'd live in a hotel. 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 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.
