I normally recommend using a water heater on the tristar controllers 
I install.  It's well worth the hassle if there is a significant 
amount of power being dumped.  I use a relay (battery or inverter 
powered) via the thermostat to transfer the current to a space heater 
when the water is hot.  Obviously the relay needs to be able to 
handle the current, which tends to be high.  Also you will need a 
suitable wire run from the battery shed to the hot water tank.  A bit 
of power loss in this wire run is no big deal.
