matching steam supply to load & room temp

Therm_lag

I understand that 40% of EDR is in piping.  To avoid overfiring above  building load, has a practice of boiler 2-stage firing been attempted, along with insulating distribution piping, especially including riser pipes on exterior walls?   I believe this would allow system to: 1) fill on high fire (limit the number of cycles to achieve complete fill), 2) "percolate" on low fire, and 3) automatically "balance" steam distribution by rate of condensation, based on temperature at locations of each radiator.

hmm

"Percolate" doesn't sound very efficient in a steam system.

thats exactly the thing to do.

we do it alot and the customers always report back with positive feedback.
