Optitherm Duo : for substantial energy savings

Optitherm Duo is a set of 2 biofuel boilers stacked on top of each other in a single 60 cm-wide casing.

The boilers are available in 24 and 32 kW outputs.
Optitherm Duo boilers are therefore available in total outputs of 48, 56 and 64 kW.
Installing an Optitherm Duo boiler enables you to match the power supplied as closely as possible to your current heating requirements, for :
- significant fuel savings;
- extend equipment life;
- benefit from the safety of two boilers.

Compatible biofioul F30

PERGE has always invested in innovative technologies, particularly in clean combustion techniques.

This pragmatic approach is based on a process of continuous progress, however minor, to improve everyday life for everyone. That's why PERGE Optitherm low-temperature oil-fired boilers are compatible with F30 biofuel.

They can continue to operate with any heating oil you may have in your tank. Then, if you decide to switch to biofuel F30, they can run on the new biofuel without changing your burner.

What is biofioul F30 ?

Biofioul F30 is a new kind of energy. It is a biofuel composed of 70% domestic heating oil to which is added 30% renewable energy, in the form of rapeseed methyl ester (RME).

As a renewable energy source, RME can significantly reduce CO2 emissions, below the 300 g/kWh threshold that will be the maximum permitted from July 1, 2022.

Optitherm Duo : simple installation and operation

Like all PERGE biofuel boilers, the Optitherm Duo features the Stoptherm system, which enables operation without return temperature limitation and without the need for a mixing valve. Direct connection of heating circuits to the boiler greatly simplifies installation.

Optitherm Duo can be fitted with the RTE3 burner-based climate control system for total modulation of the power delivered to the water. Heating and DHW inputs can be used to retrieve this information from an existing control system.

Optitherm Duo : cascade installation

For even greater flexibility, an Optitherm Duo cascade can be installed with up to 4 cascade stages. One stage can control an Optitherm Duo or a burner within an Optitherm Duo.

Application example :
- 4 Optitherm Duo boilers, each with an output of 64 kW, with 64 kW switching per cascade stage for a total output of 256 kW.
- 2 Optitherm Duo boilers, each rated at 64 kW, with 32 kW control per cascade stage, for a total output of 128 kW.

Robust and simple

The Stoptherm device prevents dew point without the need for a mixing valve. This means the boiler operates at the temperature required, without the need for additional hydraulic accessories. Thanks to the factory-fitted Class 7 control, you'll get top performance in terms of reduced consumption.
Models with DHW production are equipped with a 90 or 150-liter 316L stainless steel anti-legionella storage tank.

  Exchanger body warranty : 10 years. The warranty on the heat exchanger body is extended from 3 to 10 years if you take out an annual maintenance contract with a professional, from the time the boiler is commissioned and without interruption for 10 years.
