Hoval launches second generation UltraGas
Hoval has launched UltraGas® 2, the latest generation of gas condensing boilers, which brings even higher efficiency to the features of the first UltraGas® generation.
UltraGas® 2 models are available with output ratings from 125kW to 1550kW (250kW to 3,100kW as a double boiler), and in 10 bar versions for 720, 1100 and 1550kw units.
UltraGas® 2 boilers are designed for easy integration with existing systems and have the ability to work with any flow/return temperature difference (Delta T) for optimum flexibility. With a maximum operating temperature of 95Deg.C they are ideal for use in district heating/heat networks applications, and can in future will also be able to operate on biomethane and hydrogen.
At the heart of the new design is the patented Hoval TurboFer® heat exchanger, which combines a unique design with special injection technology to generate turbulence on the heating gas side. This increases heat transfer and boosts efficiency by as much as 20%
Ease of installation has been a key element in the design, so there is no need for system components such as a circulating pump or hydraulic separator. The amount of pipework in the TurboFer® heat exchangers has also been reduced to minimise weight, resulting in a lightweight, compact design. For example, models up to 450kW are less than 800mm wide and will fit though a standard door.
