Hi All,

I am thinking of building a heavy-duty regulated dc supply to drive some power resistors as heat for a small project green house...does this sound like something that makes sense??? I mean I want to do it as efficiently as possible as it will be running off a battery bank so i need it to be 12v dc

Whats the regulated DC supply for??
you can run the resistors straight off the battery and throw in a fuse for safety.

Then, as Mcgyvr says, you don't need a regulator. Just use appropriate resistors. But unless your greenhouse is very small your battery life between charges will be short. How many Watts do you plan to dissipate?
