I've recently moved into a 1986 Colonial home in central-CT and have noticed the furnace has begun to struggle with our currently harsh winter. It wasnt [I]great[/I] before now, but definitely wasnt this bad. There are only 2 occupants; my wife and I. Previously there were 2 adults and a 20-25 year old girl. The furnace is a 2-3 year old Weil-McLain Gold and runs on oil. The house has 2 zones. Temps have been in the single digits with wind chills below zero. I must admit I'm a novice when it comes to HVAC stuff, so apologies in advance. Here are some pics I took of her, hopefully it can shed a little light. I've been told that perhaps the call temp is too low or the mixing valve needs to be adjusted?

After this brutally cold winter, we've had some warmer weather the past few days. I came home from work yesterday to find a wet spot (18" diameter) on the floor. I figured it might be the backflow preventer failing again so I closed the supply valve for it. Today I came home, and I noticed the leak in the same spot, directly beneath a quarter-turn boiler drain (put my finger inside it and it felt wet). Then I looked beneath my circulators and there two more small spots. One is from another q/t b/d and the other is from one of the Webstone circulator isolator valves. In the three years I've been here I've never had a leaky valve. Now 3 start leaking? How?
