1 Reason For
Quite Quiet Noise Level
At only 33 decibels, the KI21RAF30 has a quite quiet noise level compared to most of the other fridges of a comparable age and spec to the KI21RAF30. Across all the Built-in fridges that were released around the same time as the KI21RAF30 the noise levels range from 33dB to 44dB.
Other 33dB noise level refrigerators currently available which you might want to consider include the Siemens KI41RAD30[plb_1739969_price] which is cheaper.
Alternative fridges with a louder noise level that you might want to look at include the Bosch KIR31AF30[plb_1665975_price] (33dB), or the Siemens KI31RAD30[plb_1737718_price] (33dB).
6 Reasons Against
Only SN (Subnormal) Climate Class
This fridge has a SN (Subnormal) - T (Tropical) climate class, which is the most frequently found climate class on fridges of this age and type.
Does Not Have a Water Dispenser
Most fridges that were launched around the same time as the KI21RAF30 do not have a water dispenser. The Siemens KI21RAF30 is no exception to this as it too does not have a water dispenser.
Quite Small Fridge Net Capacity
Refrigerators of a comparable age and spec to the KI21RAF30 have fridge net capacitys of between 30L and 460L, and the average fridge net capacity is 190L. The Siemens KI21RAF30 has one of the smaller fridge net capacitys (only 144 liters) amongst fridges of this age.
If you want a refrigerator with a bigger fridge net capacity then you might also want to consider the Siemens KI18RV62[plb_2360302_price] (150L) which is also cheaper.
Only Three Door Balconiess
The KI21RAF30 is a three door balconies refrigerator. Most of the other Built-in fridges that came out more than two years ago have between two and four door balconiess.
+3 More reasons against
Quite High Connected Load
Across all the Built-in fridges that were launched around the same time as the KI21RAF30 the connected loads range from 60W to 1,000W. With a connected load of 90 Watts, the Siemens KI21RAF30 has one of the higher connected loads amongst Built-in fridges of this age.
Quite High Current
At 13 ampere, the Siemens KI21RAF30 has a quite high current compared to most of the other refrigerators that came out more than two years ago. Across all the refrigerators that have been available for a comparable time to the KI21RAF30 the currents range from 1.1A to 16A.
2 Other reasons to consider the Siemens KI21RAF30
OK Running Costs
This Built-in refrigerator has an energy efficiency classification of A++, and the KI21RAF30 is typical compared to the other 172 Built-in fridges that were released more than two years ago that we have assessed for running costs. Based on average energy prices and usage levels, we estimate the KI21RAF30 will cost £228 over 24 years to run.
Released Over Three Years Ago
It was over three years ago when Siemens released the KI21RAF30.

Total running cost over 10 years
Running costs for this fridge have been estimated based on other similar fridges. If you know how much electricity and water the Siemens KI21RAF30uses then please let us know by entering those figures in the boxes above.
Running this fridge over 10 years will generate 1.1 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 30 tree seedlings and grow them for 10 years.
