Long overdue upgrade yields huge savings

  • Upgrading the 30-year-old liquid storage heating system saves nearly € 70 000 in energy costs annually
  • The significant € 335 000 investment could be recuperated in under 5 years

Rubber manufacturer from the Czech Republic implemented an energy-saving project to replace its steam heating system for liquid storage by a more efficient electric unit.

The liquid-storage facility was last renovated in the early 1980s. The old steam-heated pipes were customary of that time and subject to frequent leaks and breakdowns, leading to heat loss and repairs costing around € 1 500 a year. The system was difficult to maintain, control and measure. The new electric-heated cables and themorstat allow greater control (+5°C range).

Key benefits

The new electric-heated liquid storage system cost Synthos around € 335 000, but the yearly energy savings of around 6 930 GJ generated energy cost savings of some € 70 000 annually. The new heating system also reduced operating costs by € 1 000 per year. Combined savings mean the payback period could be compressed to 4.7 years.
