I called 1800HOTWTR, and Marcus came out to inspect my Rheem 135ltr gas Hot Water System. It was 19 years old and had done its job. He gave me a quote , a Rheem Stella 330 gas Hot Water System, 10 year warranty, Tempering Valve, all installation & take away old Heater. We were happy with his quote. He had this one in stock and was able to install later that day. We happy with his work and we had hot water again.
