We have a ranch that was built in the late 50's early 60's. We have a boiler, so each room has one or more base registers. With that said it limits what I can put against each wall that has one & some registers are almost the size of the wall. How do I get around them without blocking the heat or causing a fire hazard. Here is a picture from a bedroom in my house. I will be posting more pics from our house that will show more. Any Suggestions??
