Hello guys. I have an Alpine gas condensing boiler model #: ALP080B. The boiler runs great but today it was 7 degrees all day outside and I couldn't get the t-stat in the house to go past 67 with it set on 70. Sometimes it would even drop to 66. This has been going on all day. I wish I can give some supply and return temps, but while I'm looking at the boiler, they fluctuate constantly. I see the supply temp ranging from 150 -180 at different times and return goes as low as 150 as well but fluctuates also. On warmer days, the boiler has no problem getting the house temp up. What can I do?
