I am about ready to take a bat to my heating system. We have a 32 year old Crown Jamaica boiler for our steam heat system. Original everything, I find myself running down to it several times a day when the heat doesn't come on. I find that if I tap the pigtail under the presurtrol she fires right up. No fun getting up in the middle of the night to a cold house. I feel like "the ol man" in that movies " Christmas Story" where the father keeps running downstairs to do battle with the furnace.
