Description
NEFF N70 Built-In Compact Oven with Microwave Function
This stainless steel N70 compact pairs a 45-litre oven with a 900 W inverter microwave, offering 17 heating methods, Air Fry and Home Connect in one built-in unit.
The C24MR21N0B puts a full compact oven and a 900 W microwave into one stainless steel built-in appliance, 45.5 cm high and 59.6 cm wide. It suits smaller kitchens that cannot spare room for both, and makes an able second oven in larger ones, matching classic stainless kitchen schemes.
What sets it apart is combination cooking. The microwave works alongside heating methods such as the full width grill and hot air grilling, while Inverter Technology feeds power in gradually across five levels. Dinners cook in less time yet still colour and crisp the way they would in a conventional oven.
Ideal For
The stainless steel finish with steel-trimmed touch controls sits naturally alongside classic appliance schemes, bringing oven and microwave together in one tidy 45 cm compact niche.
One housing replaces two appliances. You gain a 45-litre oven with grill, microwave speed and an Air Fry setting, and lose nothing but the countertop clutter.
From dough proving to plate warming to combined microwave grilling, 17 methods adapt to whatever the week brings, with Home Connect keeping settings a phone tap away.
Key Features
Maximum microwave power of 900 W across five settings, regulated gradually so defrosting and reheating happen evenly rather than in harsh bursts.
Circulating air, conventional heat, bottom heat, full and half width grills, dough proving and more give this compact the range of a full oven.
The dedicated Air Fry function pairs with the included Air Fry & Grill tray, crisping food in the oven instead of on the counter.
A Full Touch TFT screen presents settings clearly, with temperature proposals, an actual temperature display and a heating-up indicator as standard.
Control the oven from the Home Connect app, call on the Oven Assistant, or use voice commands through a compatible assistant.
The drop-down door is damped for soft opening and closing, with triple glazing and heat-reflective glass keeping the front cooler.
A second oven that pulls its weight
Compact ovens often end up as glorified reheaters. This one refuses the role. Three shelf positions, LED lighting and 17 heating methods make the 45-litre cavity a legitimate place to roast a chicken or bake a batch of scones, and the 900 W microwave means it also covers the quick jobs a main oven cannot. Installed above a single oven, it effectively doubles your cooking capacity in busy weeks.
Even heating, from thaw to table
Inverter Technology is the quiet advantage here. Instead of switching full power on and off, the microwave regulates its output continuously, and in longer operation caps power at 600 W for gentler results. Frozen mince thaws without grey cooked patches. Leftover casserole reheats evenly to the middle. And because microwave power can combine with the grill or hot air, you get speed and browning in the same programme.
Everyday convenience, properly considered
NEFF has thought about the unglamorous parts of ownership. EasyClean loosens residue with heat and moisture so the cavity wipes clean quickly. The control panel locks to keep curious hands safe, automatic safety switch-off and a residual heat indicator watch over the appliance, and the SoftClose door never slams. Home Connect adds remote monitoring and control from any room, plus voice control through a compatible assistant. With the combination grid, universal pan and Air Fry & Grill tray included, it is ready for real cooking from day one.

| Baking days | 17 heating methods | Dough proving, circulating air and conventional heat give bread and bakes the conditions they actually need. |

The Verdict
Strengths
- Combined 45-litre oven and 900 W microwave
- 17 heating methods with Air Fry function
- Inverter Technology for gradual, even microwave power
- Home Connect Wi-Fi with voice control support
- Triple-glazed SoftClose drop-down door

Considerations
- Installation needs a hardwired 3.6 kW, 16 A electrical connection by a qualified electrician; there is no plug on this appliance.
- Maximum oven temperature is 230 °C and there is no pyrolytic self-cleaning; the EasyClean programme assists manual cleaning instead.
- It must be built into a compact 45 cm niche measuring at least 56 cm wide and 55 cm deep.
