First you will need to isolate the domestic water supply and hot water going to your faucets. Then just pumping thru the boiler a 50/50 mixture of white vinegar and water. The longer you do this, the better. Then rinse wit fresh water. When you connect back the supply and hot water, don't be surprised to smell vinegar for an hour or so.

The pump in the $100 flush kit I've seen is just an Attwood WaterBuster cordless utility pump that Wal-Mart sells online for around $35. A $20 bilge pump for a boat might also work if you have a 12V battery around to run it. A/C Utility pumps seem to start around $70 but I'd rather not mix 110V with water if I don't have to.
