Worthvalue and easy to install

DuothermWith a limited resort to electronic PERGE OptiCondens oil condensing boilers may deliver 2 different heating temperatures directly from the boiler, without any additional hydraulic accessories (i.e. 1 under floor heating loop + 1 radiators loop). The hydraulic installation is thus simplified.


More comfort

All OptiCondens models are factory fitted with PERGE RTE outside temperature controller, for more comfort at low price.

DHW is assured by a 316L stainless steel tank available in 2 capacities : 90 or 150 liters. Hot water is thus rapidly available, even in the case of important needs (200 liters of hot water at 40°C in 10 minutes with a 90 liters tank, 270 liters of hot water at 40°C in 10 minutes with a 150 liters tank. Cold water : 10°C. Storage at 65°C)

Simple and reliable


The dew point is avoided thanks to the Stoptherm device, without any mixing valve. Equipped with the outside temperature controller, PERGE Optitherm oil boiler will achieve significant results in reduction of energy consumption.

The 904L stainless steel condenser is designed with high quality matrials and confers very good performances to the boiler.

Why choose oil ?

Oil is easy to store and available everywhere. Moreover, it is a very powerful fuel (10 kWh per liter)

Oil has greatly changed in order to reduce its environmental impact. The oil condensing boiler technology allows to reduce energy consumption significantly (Up to 30% compared to a traditional boiler). Its level of sulphur has been divided by 6 in the last 40 years.

Oil boilers may be twinned with renewable fuels such as biomass or solar powered system.
