    Perfect fit, great delivery service!
    Great unit that was purchased to replace an older Rheem unit that was over 15 years old. This unit was a perfect fit with no additional modifications required. Great delivery service too!

    Rheem replacement
    We bought a Rheem 400 litre in 2002 it was 19 years old when it died. I couldn't be happier with the new Rheem 400 litre now. All the pipes on the new one fitted perfectly with the old. It was a clean swap over, such an easy job for the tradesman. I always go to Appliances online, they always price match and I get a great deal.
