Minneapolis Steam Control System
My old house (3700 SF) is heated by a one-pipe steam system powered b y a relatively new Smith GSX residential boiler.
Heating is very uneven. Radiators nearer the boiler heat quickly and satisfy the thermostat while those farther away heat slowly and incompletely. I recently discovered what purports to be a solution to this problem known as the Minneapolis Steam Control System in a paper written by one George Peterson. This scheme involves the installation of a relay in parallel with the thermostat wiring. When the thermostat is satisfied the contacts in the relay close and the boiler continues to fire until shut down when the far radiator vents close and steam pressure reaches the pressurtrol cut-off setting. A description with wiring instructions can be found by googling: "Correcting Uneven Heating in Single Pipe Steam Buildings: the Minneapolis Steam Control System George Peterson Minneapolis Energy Office". Is this a
viable solution to my problem?
