It sounds like you have a lot of radiation for the square footage you are heating. That is the way to go, and it definitely allows you to use lower boiler temperatures. On cold/windy days, my radiation has a hard time keeping up with the boiler at 160 degrees...then again I do live on a small hill with about 500 acres of wind-tunnel creating fields to the West. You can say that conditions are "extreme" at times.jpen1 wrote:If you plumb that system right a low mass boiler will handle it without any problem.
That is a big "If". You would defiantly have to have it piped with a bypass, or in a primary/secondary fashion. Either way, it would probably run a long time to get the system up to temperature. As long as the heat loss of the house is less than the boiler's net output it would catch up eventually, but you probably wouldn't want to use a set-back thermostat.
