I have a house approximately 50 years old. The heating system is a hot water system which heats water and pushes it through a series of registers in each room. Unfortunately many of the registers (about two feet in height from floor to top) are located directly beneath windows.
In my bedroom I have heavy pleated window curtains that I draw closed at night. Seems to me that the curtains look a bit puffy or inflated during the heating season and it is almost like they are puffy because they catch/trap the rising radiant heat from just below the bottom of the curtain (where the register is). I have this feeling that the heat is rising/escaping up into/behind the curtains and right in front of the [cold] window glass instead of up/out into the room.
Is there anything I can buy at a home improvement store to tuck the bottom of the curtains in towards the wall or perhaps to attach to the top of the register to deflect the heat up/away from the register? I tried holding back the curtains more towards the window/wall and I can feel the heat now flowing in front of the curtains instead of behind them.
Thanks, Walter
