Reducing energy costs without rebuilding your kiln
For many ceramic producers, the current situation is clear: energy costs are high, volatile, and difficult to plan, while margins are under pressure.
Large-scale investments are often postponed. But doing nothing is not a neutral option, because inefficient kilns continue to consume energy every day.
The key question is therefore:
Where can costs be reduced quickly, with limited risk and without disrupting production?
At Keramischer OFENBAU, we have been focusing on exactly this for decades: targeted optimisation and retrofit of existing kiln systems.
Unlocking savings in existing plants
In many cases, significant efficiency potential can be realised without major structural changes:
EnerViT-based optimisation of gas-fired kilns
– up to 50% reduction in gas consumption
– improved combustion, heat utilisation, and process stability
– implementation during planned maintenance windows
Targeted modernisation measures
– reduction of heat losses and stabilisation of temperature profiles
– lower reject rates and more consistent product quality
The result: immediate and measurable reduction in operating costs, often with very short payback periods.
Adding flexibility where it matters
Beyond efficiency, flexibility is becoming increasingly important.
Where sufficient electrical power is available, existing gas-fired kilns can be upgraded to hybrid operationwith gas and electricity:
– ability to balance between energy sources
– reduced exposure to gas price volatility
– increased independence from supply constraints
This enables operators to actively manage their energy mix instead of being locked into a single source.
Why act now?
Energy efficiency and flexibility are no longer long-term topics.
They are immediate levers for improving competitiveness.
– lower energy consumption reduces cost directly
– flexible operation mitigates price risks
– stable processes improve yield and planning reliability
And most importantly: these improvements can often be achieved within existing infrastructure.
The takeaway is straightforward: significant savings do not always require new kilns, but a better use of the ones already in operation.
