Flexible heat generation independent of the mains gas network

At the Nuremberg Animal Shelter, the Hoval UltraGas 2 (300) gas condensing boiler ensures a reliable and sustainable heat supply. Gas-adaptive condensing technology utilises alternative gases and makes the system independent of the mains gas network. 

Challenges in the existing building

The Nuremberg Animal Shelter needed a new heat supply for its premises, which cover more than 3,000 m². The existing oil-fired heating system consisted of three outdated oil-fired boilers, with consequentially high running costs. As neither gas nor district heating connections were available, a solution that did not rely on a piping network had to be implemented, and one that could be installed whilst the facility was in operation.

Project data 

  • Building type: Refurbishment (commercial / public) 
  • Location: Nuremberg, Bavaria (Germany) 
  • Area supplied: > 3,000 m² 
  • Heating solution: UltraGas 2 (300) gas condensing boiler + 2× Belaria pro (50) heat pump
  • Output values: ~300 kW (calorific value) UltraGas 2 (300) , 2 × 48 kW Belaria pro (50)
  • Energy source: LPG / BioLPG from a 6,400 litre underground tank 
  • System components: UltraGas 2 (300), Belaria pro (50), EnerVal buffer storage tank, TransTherm aqua F, TopTronic E 

Gas flexibility as a planning parameter

The Hoval UltraGas 2 gas condensing boiler can operate with natural gas, LPG, BioLPG, biomethane and hydrogen blends without the need for any adjustments. This ensures that the choice of energy source remains flexible throughout the entire life cycle and can be adapted to future market and infrastructure developments.

Hybrid architecture for high efficiency in the existing building

The new system combines two Belaria pro (50) air-to-water heat pumps, each with a heat output of 48 kW and flow temperatures of up to 70 °C, with an UltraGas 2 (300) to cover peak loads. The gas condensing boiler has an output of just under 300 kW and is supplied by an underground 6,400 litre liquefied gas tank. Two EnerVal buffer storage tanks stabilise the hydraulic system and improve system efficiency. Domestic hot water is heated by a compact fresh water station. 
 

Combination Belaria pro (50) and UltraGas 2: powerful and sustainable

Advantages at a glance – Hoval UltraGas 2 

  • Cost-effective operation – economical heat supply across the full and partial load ranges 
  • Security of investment – future-proof technology with broad gas compatibility 
  • Compact dimensions – making transport, installation and integration easier 
  • H2 and biomethane – suitable for future gas qualities 
  • Simple system integration – straightforward hydraulic integration into existing heating systems 

Digital system logic for transparency and scalability

The TopTronic E controls the entire system, coordinates load distribution and provides comprehensive visualisation. The system architecture is modular in design and is ready for future expansions, such as the integration of photovoltaic systems or additional heat generators.

Outcome

The Nuremberg Animal Shelter now has a robust, efficient and scalable heating system. The combination of hybrid technology and UltraGas 2 ensures security of supply, high efficiency and long-term flexibility in the choice of energy source.
