      • Works Great
      • February 25, 2012

      We built a small cabin at 2,200 feet elevation. We did not want a tank water heater to have to drain each winter. We researched the reviews on all the tankless electric heaters and this one had the most consistent results. We purchased the 27 kw model knowing the ground water temperature from our well in winter would be a challenge and we have more than enough hot water to handle a shower and washing machine running at the same time. This product met all our requirements. Saved space in a small cabin, no draining 40 gallons for winter and it provides hot water in the same time a tank heater takes to get the water to the tap. All things considered an excellent purchase for us.
