KitchenAid Architect Series II KGRS308BSS Gas Range Review$1,715.95
Efficiency / ECO
We like to remind consumers that testing range and oven efficiency is a very tricky thing to do, as it's difficult to measure the energy that's lost, and there aren't any Energy Star ratings for ovens at the present time. All we can really do is measure the energy used with the performance we tested.
Since the KitchenAid KGRS308BSS rangetop performed so well and guzzled a normal amount of gas, we can infer that the range uses its energy in an efficient way, at least compared to its competitors.
In our audit of the manufacture stated energy consumption, we found that most of the elements did what they were supposed to do. However, we did see two burners using a different amount of gas than advertised. The 9,500 BTU/hr burner used too many, and the 5,000 BTU/hr simmer burner used too few. Fortunately, this isn't a huge deal, as they all but cancel each other out in common use.
While the performance was phenomenal, the oven's display of raw power—the preheat time—wasn't that impressive, which made sense, as the oven did guzzle that much gas (17,788 BTU/hr). So it seems that there is low-ish power with a low-ish power draw, so things seem fairly efficient down below.
