What does it cost to run?

At a maximum of 2,500 W power draw, an hour of use at 35 ct/kWh (German electricity price) costs about 88 cents. That applies at full load; real cooking and working cycles usually run lower.

Calculation basis: 35 ct/kWh (German electricity price, 2026, rounded). Values from the manufacturer data sheet; actual costs depend on use and tariff.

Build quality & everyday use

What carries the Rommelsbacher THS 2590 in everyday use: Works with any pot (no induction requirement, stainless steel, aluminium, enamel, glass) and Robust & long-lasting (5.2 kg) (solid cast iron, fire-enamelled steel housing). We have to be honest about the weaknesses: heats up slowly & cools down slowly, since cast-iron inertia means no quick reaction.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“Rommelsbacher THS 2590 Cast-Iron Double Hotplate: works with any pot and robust & long-lasting (5.2 kg), and the trade-off is that it heats up slowly & cools down slowly. At 8.4/10 a fair deal from €104.”

Frequently asked questions about the Rommelsbacher THS 2590

What is the advantage of a cast-iron hotplate?

A cast-iron double hotplate like the Rommelsbacher THS 2590 works with any cookware; unlike induction, you do not need magnetic pots. The solid plates store heat well and are extremely robust and long-lasting. Ideal if you want to keep using your existing pots (including aluminium or glass) and prefer a low-maintenance appliance without electronics.

Why does a cast plate heat up so slowly?

The solid cast iron first has to warm through completely before it passes the heat to the pot, which takes a few minutes. In return it then holds the temperature very evenly and still gives off heat after switching off (use the residual heat!). If you need fast heat-up and second-precise control, you are better served by induction; if you appreciate even, sluggish heat, by cast iron.

Rommelsbacher THS 2590 or an induction hob?

The cast-iron Rommelsbacher takes any pot, is extremely robust (Made in Germany, 5.2 kg) and needs no electronics, but heats slowly and regulates only in steps. An induction hob (AMZCHEF) is faster, more efficient and more precise, but needs magnetic cookware. Rule of thumb: keep using existing pots and longevity: cast iron; speed, efficiency and precision: induction.

What does the 7-step switch mean?

The 7-step switch regulates the heating output in seven levels by switching the plate on and off at different intervals. That is a proven, simple technology without sensitive electronics. It does not offer truly infinitely variable fine control like infinitely variable rotary dials or induction, but for most cooking and frying the seven levels are sufficient.
