3 Reasons For

Running Costs Are Very Low

This refrigerator is rated A+++ for energy efficiency. The KI21RAF40 is in the cheapest 3% of all 81 fridges that have been on the market for more than a year that we have analysed for running costs. Based on average usage levels and energy prices, we estimate the KI21RAF40 will cost £153 over 24 years to run.

This refrigerator has a SN (Subnormal) - T (Tropical) climate class, which is the most commonly found climate class on refrigerators of a comparable age and type to it.

Chart Edit

Quite Quiet Noise Level

Refrigerators that are a similar age to the KI21RAF40 have noise levels of between 33dB and 55dB. When compared to other Built-in fridges that were released one year ago that we have assessed, the KI21RAF40's noise level of only 33 decibels is one of the quietest.

Other 33dB noise level fridges currently available which you might also want to look at include the Siemens KI41RAF30G (£609.99), or the Liebherr IK 1610 (£478.47) which is cheaper.

Other refrigerators with a louder noise level that you might want to look at include the Neff KI1213D40 (£607.52) (33dB).

3 Reasons Against

Does Not Have a Water Dispenser

The Siemens KI21RAF40 does not have a water dispenser, although it is worth noting that most of the other Built-in fridges that have been available for a similar time to the KI21RAF40 also do not have a water dispenser.

Chart Edit

Quite Small Fridge Net Capacity

With a fridge net capacity of only 144 liters, the Siemens KI21RAF40 has one of the smaller fridge net capacitys amongst refrigerators of this age. Across all the refrigerators of this age and type the fridge net capacitys range from 100L to 330L, and the average fridge net capacity is 190L.

If this Siemens refrigerator fridge net capacity is too small for you then you might also want to consider the Bosch KIR31AF30G (£599.99) (172L and cheaper), the Zanussi ZBA23042SA (£477.18) (208L and cheaper), or the Siemens KI41RVS30 (£537.97) (211L and cheaper).
