One thing people notice when they enter my house is that all of my electrical outlets on the outside walls have safety plug covers in them. They find them odd because we do not have any small children so they ask why do I use them?
It’s simple, energy conservation to save money on my electric and heating bill. Older houses were not built with the same kind of conservation in mind as they do today. You will often find that you can feel quite a breeze coming through the outlets of your outside walls. Try it and see if you can feel cold air coming through. If so then you are wasting heat in the winter and wasting cool air if you have air conditioning in the summer. There are two things you can do which are easy to install and fairly cheap to purchase.
The first is the safety plug covers. They stop the cold or warm air from entering your house when you don’t want it to. They are a simple and cheap way to save on your heat and hydro bill. I just checked and you can get a 12 pack on Amazon for under $1. Mommy’s Helper Outlet Plugs 12 Pack
The next is to add foam gasket insulators to all of your outlets. They are simple to install. You just take off the cover plate and add the gasket to the outlet and put the plate cover back on. In a matter of seconds you are on your way to stopping drafts from entering your home.
