> Heck, Bird + CD have water loads that use tap water. 

Used Altronic loads like the 9705 are typically under USD $500 used and about $900 new. The 9705 is good to 5KW and higher power models are even more prevalent on the used market.  They do require running tap water at about 2-5 gal./min. and can be connected with a standard 3/4-inch garden hose.  A flow sensor is interlocked with the transmitter to kill power when flow drops. 

During college, I used a 25kw model connected to a deep sink.  Crank the tap on the faucet and start pumping out serious power.  Hot water output is dispensed in a sink drain.  Even at 25kw, the resulting water with adequate flow feels quite warm but never hot.
