"My dissatisfaction with my Weissmann boiler"
I have carefully monitored the fuel consumption of this boiler and compared it with my previous boiler. It is model Vitorond 100 and heating a single story house of about 2200 sq. ft. Fuel(furnace oil) consumption during the first full season of use was only 20% less that with my previous furnace. I had been assured by the supplier/installer that I should experience a savings of possibly in the upper 30% range. Your comments would be appreciated. Thank you.

I can't manually control the inside temperature of the house. Unit shuts down when it's cold outside. The boiler temp is at 165 degrees but the circulator won't run. The inside temp gets down to 60-62 then the circulator turns on.(sporadic, not constantly) Did it once last winter, but now it's done it twice in two days.
