i heard you need at least over 180 fahrenheit for steam, otherwise the radiators fill with water.
i keep getting alot of offers for condenser boilers with modulation. But my radiators use water
i dont know what to do. This isnt my expertise. I found out how to size boiler at least, my EDR is 175 with 6 cast iron radiators.
thus if average water temp is 170, i need 30k BTU. Anyway, im not sure if these offers are worthy. How do these contractors know if my water temp is hot enough to condense? and that return temp is low enough?
