All<br> So I had the first of 5 boiler makers / plumbers show up and tell me what they can do. This guy said the boilers he installs are 24VAC powered , he did not think you could easily run them off batteries; and that I should speak to an electrician . <br>
<br>The funny thing I still can not figure out is, why the hell do boilers user AC and not DC ? Does anyone know why ? <br><br>In other news the system that runs with out electricity, a/k/a a thermopile powered microvolt boiler, from what I have read, is now outlawed as they are to inefficient . <br>

In any case you will need some source or electric power to run the<br>
thermostat. For my set up I have a gas fired boiler with a pilot light<br>
and a small battery/inverter combo to run the thermostat.<br>
<br>
Thermostat circuits seem to be 24 volts AC in this country. So I have<br>
a 12 volt battery with a 100 watt inverter (small cig lighter type)<br>
that puts 110 Volts into the transformer for the furnace when there is<br>
a power failure. I do not have it automated, but I should at some<br>
point do that.<br>
<br>
I have not investigated to see if the control circuit will work with<br>
DC. If so then one could just get a couple of 12 volt 7AH gell cells,<br>
wire them in series and home brew a small 24V dc trickle charger to<br>
power the whole thing all the time. This is real easy using linear<br>
technology by picking up a transformer and 4 diodes from Radio Shack.<br>
<br>
I hope this helps.<br>
