Hot Water Baseboard Heat, Cold Rooms
I have hot water base board heat. About a week ago, I noticed I couldn't get the house to go above 62 degrees. When I touch the baseboards the two rooms at the beginning of the loop are hot, but as I go farther through the house the units are colder and colder leaving the two bedrooms freezing cold. Last winter I had a problem with a pipe freezing, so now I keep a small heater on in the basement to avoid this happening again. The circulating pump comes on and is only a year old. As I said the problem started suddenly. What could be wrong? Can I fix it myself?
