UltraGas® (15-90)

Innovative condensation design for single-family homes and multiple occupancy dwellings... 

UltraGas® (15-90) and (125-2000D)

Impressive efficiency due to improved condensation design using patented aluFer®

Hovel aluFer® technology

The special design of the aluFera® heat exchanger increases the surface area for heat transmission by a factor of 5. This means that 10-20% of the energy in the flue gas can be recovered, increasing the UltraGas® efficiency considerably.

The better conductivity of the aluFer®— aluminium on the inside and stainless steel on the outside — optimises the transfer of heat energy to the boiler water with added benefit of being ultra durable, making the UltraGas® highly economical.

Improved condensation design

Flue gases always contain steam, however, this condensing design allows the flue gases and the steam they contain to be cooled by an additional heat exchanger in the boiler. The latent heat in the flue is transferred to the incoming cold water, increasing the efficiency of the boiler. This is due to less fuel being required to raise the water temperature.

Modern Ultraclean® burner technology

The modulating burner means the UltraGas. adapts its output continuously to suit the heat required. The result is fewer energy-consuming burner starts, greater efficiency and significantly lower emissions.

Separate high and low temperature return flows

The UltreGas® boiler provides the optimal conditions for condensation. The is because of the stepped heat transfer between the separate high and low temperature return flows and the flue gases. This highly efficient condensation design means lower consumption of fuel and therefore lowers running costs.
