11550 kW in an ultra-small space
Vaduz, 30 September 2019. The UltraGas® (1550) from Hoval expands the upper range of the legendary gas condensing boiler series. It supplies comfortable heating for large building complexes and heating networks. The boiler is highly efficient with low emissions, all while using less than half of the floor space of common gas boiler devices in this operating range.
The Hoval UltraGas® is in a class of its own. Thanks to its optimal efficiency levels, this condensing boiler reduces consumption and increases the cost effectiveness of heating systems. A wide range of design details reduce gas consumption. The finely-graduated UltraGas® product range, starting from 15 kW, has been expanded to include a 1550 kW single boiler. All applications, from single-family houses to local and district heating centres, can now be implemented with this gas condensing product range.
Thanks to its special design, the new 1550 kW boiler needs less than half the space of common devices on the market. The construction as a standing system with upright heat exchangers greatly reduces the space required. In addition to the heat exchanger concept, the overall boiler construction saves space and enables simple hydraulic integration. The UltraGas® (1550)—just 1550 mm in width, 2152 mm in depth and 2547 in height—is particularly easy to install and position in tight spaces. The space saved can typically be used for other equipment, or reserved for future expansion.
While the UltraGas® (1550)
boiler is small in terms of the space required, it is a giant when it comes to both performance and efficiency.
"In the high operating range, the market is now turning toward condensing boilers—toward condensing technology which has already been state-of-the-art at Hoval for a long time," says Günther Köb, Product Manager of Condensing Technology at Hoval. According to Köb, "The demand for high-efficiency heat exchangers in the high operating range with minimal required floor space is particularly high in order to expand existing boilers, for example." This is why the thin design of the UltraGas® makes all the difference.
The newest and most powerful UltraGas® boiler achieves its impressive efficiency thanks to the state-of-the-art burner technology and its heat exchanger design.
The modulating premix burner ensures a high level of efficiency and low emission of pollutants across the entire operating range. The fan-premix unit generates a
homogenous and therefore optimal mixture of combustible gas/air. The quantity can be infinitely adjusted using the fan speed and modulated to the heat demand. The
burner runs through its modulation range from 328 to 1550 kW continuously and prevents start/stop operation, which requires a lot of energy and creates increased
emissions. The energy consumption of the fan also sinks with the speed.
The Ultraclean® grid burner burns the gas/air mixture in the optimal range for the minimal emission of pollutants. It is also quiet and virtually flameless.
While boiler efficiency is always inspected under ideal conditions on the test bench, the boiler shows what it can really do in real-world application. How well
can it handle varying performance requirements? How does it behave with fluctuating flow rates? Or with changing return temperatures?
The quality and class of the UltraGas® can answer these questions. It comes down to modulation on the one hand, and the high water content on the other.
The UltraGas® impresses despite fluctuations in power thanks to the burner modulation range and the intelligent TopTronic® E system control, which conveniently monitors and controls the power data. The UltraGas® can also be integrated into building automation systems using TopTronic® E interfaces.
The high water content works like a buffer to manage the flow rates and return temperatures. This provides numerous advantages: simpler hydraulic systems, lower energy consumption and fewer start/stop processes.
In addition to all the performance data, reliability, investment security and services also benefit professional users.
Hoval is the perfect partner to meet these standards. There is an abundance of services and packages for operators to select from in order to find the right solution for every system and requirement. The portfolio ranges from commissioning to maintenance and guarantee extension. These are all measures which protect your investment, enable optimal operation and make costs calculable. When it comes to maintenance, simplicity and speed distinguish the easy-to-service UltraGas®. One person can open the burner alone with just a few motions, making the heat exchangers accessible for cleaning. This saves time and money for safe, long-term operation.
Starting now, the Hoval UltraGas® (1550) can be delivered as a single boiler. It will be available as a double boiler in the spring of 2020.
