    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?

    Battery for this is impractical. You need kW.

    What kinds of the power resistors can do that?
    Why not using heater and fan?

    Yeah I didn't have the heart to tell him the battery bank would need to be larger than the greenhouse. :D
