A vent damper is a great way to save money on your heating costs. We all spend a large amount of money heating our homes throughout the winter so it seems pointless to allow a lot of this expensive energy to escape through the vents. Vents are designed to allow air into our house, but if this is cold it can have a negative effect on the heating in your house.

Vent dampers can be fitted as a way to prevent cold air from entering the house. These are actually very simple to fit. They're something that most people can install as part of a simple DIY project as long as you feel confident enough. If the ducting is easily accessible then fitting in-line dampers is very simple. It actually only involves the use of two screws which makes it a project more people can do.

Step 1 - Cleaning

Before you start to do anything else you must first clean the duct. If there is any dust on the vent or duct then this can make it much more complicated to control the flow of air entering your building. Cleaning the vent and duct is actually fairly easy. You can use a cloth to clean the outside of the vent and a vacuum to reach further inside.

Step 2 - Choosing the Damper

Now choose a vent damper which has the right degree of control. This will depend on how often you intend to open the damper. There are also vent dampers which have speed control and timer functions. Choosing the right damper now will save you a lot of money compared to if you had to replace one so that you can get more control over it.

When choosing a damper you must ensure that it's a snug fit. The damper needs to be the right diameter to fit properly into the duct work of your ventilation system. You can find out more about the right fittings by reading through the manufacturer's specifications. You will need to choose the right type of damper if you want to have the right degree of control over your temperature and air flow.

Step 3 - Attaching the Damper

Now you need to fix the damper to the inside of the duct using your two screws. Ensure that the vent is turned off before fitting the damper to avoid any problems. Also make sure that the vent is securely fixed into the duct.Check that the amperage to the power supply is correct and wire everything up together.

Step 4 - Testing

Check your work and ensure that everything is wired up properly and correctly. Make sure that everything is grounded where it should be. It's never worth guessing with electrical work, if you're unsure then ask for a professional to help you. Never be afraid to ask, professionals really do want to help you and will happily sign your work off if that's what building codes require.
