Rofco B20 vs Nero 400
This Rofco B20 vs Nero 400 comparison is for bakers weighing up two compact stone-deck electric ovens for artisan bread production. Both are single phase ovens with three baking surfaces, but they differ in capacity, deck size, controls, steam setup and power requirements.

This guide focuses on the practical differences that matter when comparing a Rofco oven in Australia with the Nero 400.

The Bottom Line
In practical terms, the Rofco B20 vs Nero 400 decision comes down to output, deck size, control and power supply. The Rofco B20 is the smaller, simpler and lower-cost option with 10AMP single phase power, while the Nero 400 gives you more capacity, larger soles and more bake visibility, but asks for 15AMP single phase and a higher budget. Both sit in the compact stone-deck electric oven category, but they suit different stages of production.
Rofco B20
The Rofco B20 suits serious home bakers and smaller micro bakeries that want true stone-deck baking in a compact 10AMP single phase oven.
Nero 400
The Nero 400 suits micro bakeries and small commercial kitchens that need more deck space, more loaf capacity and more control from a compact electric deck oven.
FAQs
Is the Nero 400 much bigger in baking area than the Rofco B20?
Yes. Both ovens have three baking surfaces, but the listed sole size is larger on the Nero 400 at 47cm x 47cm compared with 30cm x 48cm on the Rofco B20. That larger deck area is one of the main reasons the Nero 400 carries a higher loaf capacity.
Can both ovens run on standard single phase power in Australia?
Both are listed as single phase ovens, but not with the same plug requirement. The Rofco B20 is 10AMP single phase, while the Nero 400 is 15AMP single phase. That difference matters when checking what your home, studio or commercial kitchen can support.
Which oven gives more control over the bake?
The Nero 400 is the one with independent control over each heating element. The Rofco B20 is described as having straightforward controls and reliable electric heating, but independent element control is only listed for the Nero.
Does either oven make it easier to watch the bake without opening the door?
The Nero 400 does. It includes a full-length viewing window and lights on each deck, which helps you monitor progress while keeping heat and steam in the oven. Those features are not listed for the Rofco B20.
Is the Rofco B20 only for home bakers?
No. Micro Bakery describes it for serious home bakers and small batch production, and says it is well suited to micro bakeries as well. It sits between advanced home use and small commercial-style artisan production.
Why is the Nero 400 more expensive?
Based on the listed product details, the Nero 400 has a higher loaf capacity, larger baking soles, independent heating control, a viewing window, deck lights and a 15AMP setup. Those differences place it higher than the Rofco B20 in both output and feature set.
