Description
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. It is easily fitted onto the outside wall in place of the existing vent. There are no moving parts, just a clever design inside that zigzags the air, slowing it down, so it doesn’t rush in through the vent. If a greater amount of air is needed because the appliance is burning, the air can come in as fast as it likes, and if the appliance isn’t lit the air will just trickle in giving you just the amount of ventilation you need.
