Running boiler during power outage?
I have one-pipe gas steam heat in my home. Electrical power comes to the furnace, goes through a 25v transformer, and then runs the pilot igniter, and the gas control valve. There are no mechanical fans or pumps, or anything else requiring electrical power (the thermostat has its own batteries).
Periodically, we have a power outage and I would like to see if I can run the furnace on batteries. I have attempted, by disconnecting the transformer, and connecting several 9-volt batteries in series to the 2 wires that are normally connected to the transformer.
Three batteries (27 volts) ought to do it, right? Even with 6 batteries, I can elicit only a click from the furnace. Am I nuts, or is there a way to do this?
