Hey all,
I'm new here. I had a boiler die during hurricane Ida. Had a new Laars combi 199k installed today. Installer said that my radiators, mostly 100yr cast iron beasts, are on tee fittings and need to be changed to make a loop - so I disconnected those tees and made a loop instead so each radiators feeds the next radiator instead. Many of the feeds are 1/2 copper with a few 3/4. He changed the inner ch set point from the factory 120f to 180f while installing. It has now been a few hours since and it seems not to work right... Temp being displayed on boiler is 140f. Thermostat is calling for heat. Pump and flame icons are on but it doesn't reach a higher temp. Radiators are warm but not hot. Not enough to bring the house to a temperature that will make the thermostat shut off (70f). I was reading manual and thought maybe outdoor sensor is preventing it but that seems odd that factory setting will be as such. It is 15f outside. Another idea is since I have such large radiators with 1/2 feed lines - maybe circulation pump isn't able to circulate it well enough? Any advice?
