Pv for s/h/w..... [RE-wrenches]

If a tempering tank was used, plumbed in as a pre-heat to the existing H2O
heater, and a low voltage, low wattage DC heating element installed (use a
cheap glass-lined electric heater for this T-tank), and something on the
order of a couple hundred watts of PV wired in??


Paul Benson of Dankoff Solar had a similar arrangement as a dump load in his
old home, except he used the AC output of his SW to fire the electric
element.  I don't know the nitty-gritty details, but the 110 output driving
a 220 element consumed something like 500 watts--just enough to be the dump
load for his Whisper.  Think he used the SW's relays to control the whole
affair.  Said on windy days the propane never fired!


Enjoy the Sun!
