boiler temp. problems

RW Decker Heating

I have the following problem: it takes about an hour to get my water temp from 120 to 180, even after it has cycled for a night in cold weather. the house stays at set temp. but the gas bills are higher than expected. i put the boiler in September of this year. the following are my specs.:

75,000 input 60,000 output Bryant gas boiler
60 feet fin baseboard
835 sq. foot house
7 degree delta on my supply/return lines
235 net stack temp.
house has newer windows and insulation
10 feet piping in garaged but it is wrapped.

thanks for any ideas, Roger Decker RW Decker Heating

Gas pressure?

Has the manifold pressure been taken? 3.5"???? Hi Eff. or 80%? If 80 % your stack is lo...... One more Q:, What size lines supply your base?
