Engines / Re: using a gas hot water heater tank to cool lister

ok what if i used a car type radiator after the hot water tank with a senser to turn a fan on when temp. reaches 190 deg. remember the cooling liquid will be circulating through the middle of the hot water tank first. now running the exaust gas through another hot water heater, to capture that heat sooting may be a problem i'll have to make it so, a rought time cleaning can be done easy. maybe a tee at the bottom with a removable cap so it could be brushed often,also a drain. i'm sure there will be condencate problems. i'll have to give the later some thought. might not be worth the trouble. sure would be nice to capture that extra heat .i read some where it would be 28000 btus. thats a lot of heat. as for welding plates on the tank ,i've done this before and it don't ruin the glass liner much. wire welding only heats in a small area. leaving the anidotate rod in place prevents it from rusting.
