  1. Saves me money 4 Star Review

    Posted by on 8th Jul 2014

    After buying this heater, my monthly bills have dropped significantly. The heater is so efficient and after hot water starts flowing, it won't stop. Even in cold weather I have never had a problem with the water. I am really happy with this product and will definitely be staying with Rinnai heaters.

  2. Packs a punch 4 Star Review

    Posted by on 4th May 2014

    Once it starts providing hot water, it is a continous supply. Installation was more expensive than I thought. I stillwould not to recommend DIY on these units.
