I just got a call from a long time customer of mine saying that the upper floors in her home were colder than normal. These folks have a radiator system for home heating as it is an older home here in the Pittsburgh area. Radiator systems can sometimes be “tricky” to figure out. A radiator disaster can occur when they are not operating as intended. A lot of homes in Pittsburgh have radiator heating. And I must admit, they are an efficient way of heating your home.
