“We have loads more hot water than when we were on an element.  We have three showers in a row and we never run out of hot water.  In fact, we have to be careful because it is ripping hot.  This is all nice because it also knocks a big chunk out of our usual power bill!”

  • Eric Pettyjohn, West Harbour

“Our power bill came this week. $197!  In 8 years, I’ve never had a power bill starting with a ‘1’, it’s normally a ‘4’! It was a reading too, not an estimate. And that’s for the month gone, I wager it will get less over summer, so that’s fantastic!”
