I am using them for pre heating air in the firebox and they are not welded in, but with four years of corn and wood exhaust exposure they still look very nice. I have not cleaned them or oiled them down for the summers. Would be interesting to see how this material would hold up welded and wet. Rolled would be best but that would not work for you. - giddygoat Wed, 05 Jan 2011 00:57:29 +0100 /component/content/article/1-latest-news/36-an-update-on-my-leaking-boiler#comment-9 Please don't lay the blame on the corn exhaust -- The fire tubes of Baby Boiler were in similar poor condition when it was first adopted. It had only been burned hot and hard on Marth pellets. - a guest Wed, 22 Dec 2010 22:26:22 +0100 /component/content/article/1-latest-news/36-an-update-on-my-leaking-boiler#comment-8 PM me if you want pictures of my (not ready for prime time) variable feed system - Sting - a guest Wed, 22 Dec 2010 22:12:04 +0100 /component/content/article/1-latest-news/36-an-update-on-my-leaking-boiler#comment-5 As for the logic board tne electronics operate on low voltage DC. The board has a transformer that lowers the 117/120 V AC to a low voltage AC that is then changed to DC for the logic board circuits. I don't know how the electronic motor control switches on the logic board would handle the 12 volts to the motors. A small inverter might be the easiest way to run the board. - a guest Wed, 22 Dec 2010 21:07:41 +0100
