Long Beach Ed's Radiator Lab

The system is in my 3,000 sq ft stucco 1909 colonial. The original one-pipe steam was installed in 1926. There are 11 standing radiators and a five section Series 8 Dunkirk boiler with a 4" header.

By installing Hoffman Paul Vents and running them to a small vacuum pump (ebay) the distribution was INCREDIBLY improved and boiling time VASTLY reduced.

We've experimented with a "heat-timer" type (variable speed motor-timer) device to run the pump for a variable period (depending on outside temperature) before each boiler firing. Thus, in theory you can produce as low as 160 degree steam on a mild day.

Right now were wrestling with the nuts-and-bolts of the experiment, namely hunting down and repairing vacuum leaks. We've come to learn that if there is any leak, no matter how small, vacuum will find it.

But we did see potential for HUGE savings with the system. For example, full heating of all radiators went from 17 mintues on the conventional system to three minutes with the vacuum.

The lab work continues under the cloak of high security, as the Dear Wife feels there are better things that I should be doing with my time, like painting the place.

Scientists have long been so misunderstood.
