We have had a Hills Solar evacuated tube solar hot water heater for a number of years now that provided cheap hot water year round. Recently we noticed that our hot water was not as hot as we were used to it. We put it down to a cold and cloudy winter. Although once we noticed that even on sunny days there was not much hot water available it was clear something was wrong.
good thing you figure it out without spending lots of dollars. is really a great idea to used in every household.

i have a hills esteem ii solar hws with a er2 light on the controller and a t1 light showing - anyone know what this means. i am quoted $1375 to replace the controller and pump but i am not even sure what is wrong as the troubleshooting in the manual supplied is useless.
