Hi, I'm brand new to this site. Week ago, noticed no baseboard heat and checked boiler. Red light was blinking in the "brain box." Shut main power switch off on wall and restarted. Worked fine for 1 week. Last night did it again and is now doing it every 2 hours. Damper is fine, aquastat replaced last yr. Any ideas?

Hi. I'm a new (old) home owner. I've got some money left after closing and I want to upgrade my boiler. It's one zone with cast iron hot water radiators. I've received several quotes but the more I research the more confused I become! I've got quotes on installing a Slant Fin, a Peerless, and a Buderus. The quotes have all been for around 5200$. The Buderus was about 400 more than the other two. The guys that wants to install the Slant Fin said I should have a new stair stringer put it in the basement to support the weight of the boiler during install and disposal. That's gonna cost me extra and he's the only one that mentioned it. I've hear the Buderus boilers are great but they are harder to service. True?? Any input in my situation would be appreciated. Thanks
