After having the boilers in my base explode, I realized that buildcraft can be used as a cheap way to extend the range of any chunkloader to cover any desired area.
Its quite easy: First, you will need an actual chunkloaded block.
In that chunk, place a chest, filled with cobblestone, attach a wooden pipe to the chest with redstone pump to extract items, and then, starting from that pipe, build a loop of cobblestone item pipe that crosses through all the chunks you wish to keep loaded, looping eventually, back into the chest.
The constant circulation of items will keep all the chunks loaded, all for the cost of just one chunk loader.
