The innovative Hoval TurboFer® heat exchanger allows for operating temperatures of up to 95°C. It also has a specially developed heating surface that transfers heat even more effectively than other designs.
The separate high-temperature and low-temperature returns are another way to ensure cost-effective operation. This separation means the heating water is returned to the correct place in the boiler, thus producing optimum water-side temperature stratification inside it. Using the high-temperature and low-temperature returns makes the system more efficient.
A flow temperature sensor optimises operation of the heating system even further. This sensor records the precise flow temperature, enabling it to improve the control response. The through-flow is more constant and the return temperature is lower. The useful heat is utilised in the best way possible. This boiler’s increased efficiency and energy savings of up to 20% compared to a conventional gas boiler enable it to save the customer money. The investment is recovered in just a few years."
