Description of the boiler

The Hoval UltraGas

is a low-pollution and energy-saving

condensing gas boiler with the Ultraclean burner system,

a gas-fired pre-mix burner with combustion air blower.

The Hoval UltraGas

has a vertically arranged combus-

tion chamber of stainless steel as the primary heating

surface and a secondary heating surface of aluFer

com-

posite tubes (stainless steel on the water side, aluminium

on the flue gas side).

The secondary heating surface is so designed that part

of the water vapour contained in the flue gas condens

es and the heat of evaporation is utilised for the heating

circuit. The gas burner is configured as a vertical burn

er that can be swivelled up easily for maintenance work.

The UltraGas

is provided for operation with natural gas

and liquefied gas. The design principle is shown in the

following drawing.
