All<br> So I wanted to point out , I had no intention of removing any of the safety controls. I wanted to just remove some of the extra sensors / controls added to improve efficiency and lower emissions; to improve reliability by simplifying the controls and removing extra trip points in the boiler control. Most of the boilers I saw had senors to trip the boiler , IE shut it down safely , if the system is not running efficiently. IMHO I want heat when its cold, and it the system trips because its only running at 70% efficiency I will be super pissed . Other then that I wanted to , in the event of a power failure, a simple way to run the system off a battery. Either a UPS or a home brewed setup ; using an inverter and maybe a solar charger. <br>
<br>Based on what everyone said the best setup I see here is this Boiler -> Step-down transformer - > NEMA 5-20p plug -> NEMA 5-20r socket -> existing 20amp circuit . This way I could reuse a UPS I have to run the setup for some time. <br>
<br><br>Then if I wanted to in modify this for stand-by power would do this, <br><br><br>Boiler -> Furnace transfer switch*---> 24VAC Step-down transformer -> NEMA 5-20p plug -> NEMA 5-20r socket -> existing 20amp circuit |<br>
|<br> \----> 24VDC to 24VAC inverter -> 24VDC Power , batteries solar etc <br><br><br><br><a href="http://www.electricgeneratorsdirect.com/Reliance-Controls-TF201W/p1096.html">http://www.electricgeneratorsdirect.com/Reliance-Controls-TF201W/p1096.html</a><br>

<div class="im">> The 24VAC is run off the secondary of the 120VAC transformer. Look at the<br>

I agree with Brett, but as a non-licensed non-professional<br>
non-electrician (a physic degree can be a dangerous thing), that a UPS<br>
would be the best way to go.<br>
<br>
Almost restrained myself from making a comment about using a server<br>
farm instead of a boiler to heat the house.<br>
