Siemens built-in cooling 2026: iQ300 and iQ500 fridges and freezer

Siemens built-in refrigeration: what to know

A built-in fridge hides behind a cabinet door, so the kitchen keeps a uniform look. Siemens has made it a speciality, with appliances from theiQ100 to iQ700 and a mention ‘Made in Germany' on much of its Belgian product pages. At Nimestore, we stock iQ300 and iQ500.

• Quiet : 35 to 36 dB, making them discreet appliances, even in an open-plan kitchen.
• Freshness : drawer hyperFresh (adjustable humidity for vegetables), in the Plus version on the KI72LADE0, and a hyperFresh 0 °C zone on the KU22LADD0.
• Energy class : E for most, D for the KU22LADD0. This is common for a built-in, where insulation is limited by the niche.

The comparison table

Data from Siemens' official technical sheets. Public prices recorded on nimestore.com on 15 October 2026: the product page prevails, and Nimesclub members often get a reduced price.

Building your cold zone

• Large family, tall-unit kitchen : KI81RVFE0 (310 l of fridge space) next to the Bosch GIN81VEE0 freezer (212 l, No Frost, 177 cm). Same group, same after-sales service, same niche height.
• Couple, compact kitchen : KI72LADE0 at 158 cm, with a storage unit above it.
• Small kitchen, studio, bar : KU22LADD0 under the worktop, optionally with the GU21NADE0 alongside for 85 litres of frost-free freezer space.
• One appliance for everything : KI82LVFE0, with its freezer compartment.

The link with Bosch

Built-in Siemens and Bosch fridges come from the same production lines. The official Belgian catalogue, for example, pairs the Siemens KI81RNSE0 (iQ100) with the Bosch KIR81NSE0 (Series 2). In our range, the KI81RVFE0 Siemens and the KIR81VFE0 Bosch have identical spec sheets for the essentials and the same recommended price (1 149,99 €). The letter grade is also the same: V = iQ300 at Siemens and Series 4 at Bosch. Our range Bosch fridges rounds out the choice, particularly in 122 cm and with a tall freezer column.

Decoding a Siemens fridge reference

• KI = built-in tall fridge, KU = under-counter fridge, GU = under-counter freezer, GI = built-in tall freezer.
• The two digits give the height: 21/22 = 82–88 cm, 41/42 = 122 cm, 72 = 158 cm, 81/82 = 177 cm.
• The next letter give the type: R = fridge only (no freezer), L = with freezer compartment, N = No Frost.
• Then the level : N = iQ100, V = iQ300, A = iQ500, F = iQ700. Example: KI81RVFE0 = iQ300, KI72LADE0 = iQ500.

Pitfalls to avoid

• Niche height : measure it at several points. A KI81 requires a maximum of 177.5 cm, a KI72 158 cm.
• Hinge type : our five Siemens models have parallelogram hinges (the furniture door is fixed directly). If your old fridge had runners, the furniture door will need to be adapted.
• Ventilation : follow the grille and ventilation requirements in the manual, otherwise the appliance will use more energy and age faster.
• Under-counter models : they need a niche 60 cm wide and 82 cm high; this is not a freestanding worktop-height unit.
• The 4-star freezer in a fridge is not a real freezer: it frosts up and has to be defrosted by hand.

Installing a built-in fridge: points to check

A built-in fridge needs a little more preparation than a freestanding model. Here are the points to check before buying and on installation day.

• Niche width : our Siemens tall units are designed for a 56 cm wide niche, whereas the standard kitchen unit is 60 cm.
• The furniture door : it is fixed to the appliance door. Its weight and dimensions must respect the limits in the manual, especially for a large front.
• Ventilation : air circulates through the plinth and the top of the column. A plinth without a grille, or a closed wall unit above, stops the appliance from releasing its heat properly.
• Electrical supply : an accessible socket nearby, with no extension lead.
• Commissioning : follow the manual for the waiting time before connecting a transported appliance, and let it reach room temperature before filling it.

If you are replacing an old built-in fridge, look up its model number on the rating plate inside the cabinet: that lets you compare dimensions and hinge type with our models. For the installation itself, ask the shop what is possible.
