Hoval UltraGas condensing gas
boilers are available in capacities
from 50 to 1000kW, while twin
UltraGas units offer outputs from
250 to 2000kW - complete with
common flue and optional
pipework/header kits.
Independent testing (to DIN EN 676) confirms the average NOx emissions of the boilers to be less than 40mg/kWh - achieving the maximum BREEAM rating of three points relating to NOx emissions.
Net efficiencies of up to 109.5% are also achieved when tested to the requirements of the European Boiler Efficiency Directive, with CO levels of 10mg/kWh.
Featuring Hoval's Ultra Clean combustion system, the boilers use a modulating pre-mix down firing burner with up to 6:1 turndown.
