Replacing a bathroom vent, such as the one with the flaps which rattle all night. Should be a straight swap. Smaller items will be delivered using Royal Mail 24. Larger items delivered via FedEx or ParcelForce.

It has a free air equivalent of 3400 sq mm, OK for a stove up to just under 12kw (if you include leakage 12 kw is fine) which covers most stoves fitted. 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. If it’s a 100mm louvred vent then the DR21 air just slots over where the old vent cover is, and if it’s the standard plastic vent cover, even the holes are in the same place.When heating a property with either an open fire or a solid fuel appliance there are several things that one should know:

Vent caps work best in conjunction with other draught exclusion measures to keep your home warm and comfortable. Take a look at our other draught excluders range to get an idea of some more cost effective ways to keep your home efficient and cosy, as well as reduce those rising energy bills.

So, as fuel is burned, oxygen in the area surrounding the fuel source is ”used up” by the mechanism of combustion, this then needs to be replaced. The reaction then pulls more oxygen into the area to replace the ”used up” oxygen – when this ocurrs in appliances, air is pulled in via the vent to do this. So, the rate of airflow in through the vent will automatically meet the demands for the appliance, regardless of the vent style.

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. 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? All I'm asking is whether there is a safe and simple method of stopping the cheap bits of plastic that pass for external covers on these things from rattling like a banshee whenever a squirrel farts in the woods to the side of my house.

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.
