Hi Scott;

We've seen this scaling problem here with Aquastars. I quit selling them 
for the most part, because of the scaling problem and the fact that they 
don't fire at low flow rates. Nothing like selling a good customer a Staber 
washer and an Aquastar and then the Staber doesn't use enough water to get 
the Aquastar to fire! Or the frugal old lady on a rain catch cistern that 
washes dishes with a quart/ minute and it won't fire either.
I recently had a customer with a "Rannai" hotwater heater. It had an almost 
100 watt draw while in standby!  It must have had a glowbar or something in 
there. It also was not mod sine friendly. It was replaced with an Aquastar, 
since there wasn't space for a regular hotwater heater.
