Class 7 control (RC7)


RC7 is a class VII control, which simultaneously controls the temperature of the heating circuit by
- by modulating it according to the external climatic conditions;
- by adapting and correcting it according to the room requirements.

The temperature sensors are easy to install and transmit information either by wire or by radio. The device is controlled by your smartphone using the MyPerge application, available on Google Play (Android) or Apple Store (iOS). The connection is made locally via Bluetooth or internet or remotely via internet. Data exchanges are encrypted for greater security. You can control up to 3 heating circuits or 2 heating circuits + 1 domestic hot water circuit.

You have 4 operating modes:

- Winter (heating + DHW)
- Summer (DHW only)
- Absence (heating only at a programmed frost-free temperature)
- Standby (neither heating nor DHW)

 

Manufactured in France

French flagPERGE OptiPellet boilers are manufactured entirely in our factory in Portes-Les-Valence (26), where our research centre is also located. This is where we develop the products of tomorrow, efficient and environmentally friendly, economical and easy to install and use.

 

 

 

PERGE pellet boiler technology

 

Environmentally friendly

The PERGE OptiPellet pellet boilers have a combustion chamber with a 3-stage air intake for complete and clean combustion which largely meets the requirements of the EN303-5 class 5 and 7 star Flamme Verte standard for the 23, 33 and 45 kW models.

The high level of performance thus achieved results in a very high combustion efficiency, remarkable combustion hygiene (CO emissions can be less than 100 ppm) and virtually no dust emissions (less than 40 mg/Nm3). 

Economic and easy to install

PERGE OptiPellet pellet boilers can supply up to 3 heating circuits at different temperatures directly from the boiler and without additional accessories (e.g. 1 underfloor heating circuit + 1 radiator circuit + 1 independent DHW cylinder).

 

Robust and simple


Thanks to the Stoptherm device, the dew point inside the exchanger body is avoided, without the installation of a mixing valve or buffer tank. There is no risk of corrosion of the exchanger body.

 

Simple and easy maintenance


OptiPellet boilers are equipped with a self-cleaning exchanger and burner. The ashes are collected in an ash pan located at the bottom of the boiler. The ash pan can be emptied manually by the user through the easily accessible ash pan door on the front of the boiler. The large volume of the ash pan allows for a long period of operation between two emptying operations (e.g. with an OptiPellet 23 it is possible to consume 2 tons of pellets between two emptying operations.

The other cleaning operations are carried out by a professional as part of the boiler's overhaul operations. They are facilitated by :

- Pivoting burner screw on the front for easy access to the burner without defuelling the fuel.
- 180° hinged burner door without weight for cleaning the combustion bowl and access to the firebox.
- Retractable flame guide without tools.

 

Direct connection from the boiler without temperature limitation of the heating returns


The PERGE technology does not impose minimum temperature constraints, nor the installation of a mixing valve or a buffer tank. The boiler operates safely without any low temperature limitation of the heating returns.

PERGE boilers have a heat transfer medium divided into two parts, separated by a Stoptherm (2). When the burner is operating, the small amount of water in the perimeter water layer (3) surrounding the furnace and in the heat exchanger tubes (4) of the boiler is heated to a temperature of over 60°C. The dew point is avoided and, at the same time, a thermosiphon circuit is established between the perimeter water layer and the mixing chamber, which is thus heated by natural circulation.

One or more independent and direct circuits connect the mixing chamber (1) to the heating system, without the possibility of cold returns reaching the exchange surfaces.

The risks of corrosion are eliminated and the boiler's longevity is guaranteed.


Modulation of the power delivered to the water from 0 to 100% without loss of efficiency


The operation of PERGE boilers without minimum temperature constraints gives them another very interesting advantage: the heating temperature can be modulated completely, without limit, over the entire range of needs (from 0 to 100% of the boiler output).

Short cycles are avoided thanks to the large water volume in the mixing chamber and the inertia provided by the refractory ceramic of the combustion chamber.

The burner, which operates at nominal power, guarantees optimum efficiency at all times, without unnecessary electronics.

The boiler operates safely at a temperature adjusted to the actual needs of the moment without loss of efficiency.

This very high efficiency performance is supported by very low annual maintenance consumption*.

* Takes into account the losses when the boiler is shut down and the consumption required to maintain a minimum temperature to avoid dew point. PERGE boilers, by design, do not have this minimum temperature constraint.


Two heating circuits with different temperatures (underfloor heating + radiators) directly from the boiler


Duotherm SCThe PERGE pellet boilers are equipped with the Duotherm-System (PERGE patent), which allows two heating circuits with different temperatures (e.g. underfloor heating and radiator heating) to be created directly from the boiler. Each circuit is distributed at the temperature required, without the need for a mixing valve or motor.

The Duotherm-System is based on the principle of a fixed injection and re-injection bypass. The slope of the control determines and regulates the flow temperature of the heating circuit on which the controller sensor is placed (in our example, circuit no. 1). The setting of the Duotherm-System creates a second slope that determines and regulates the temperature of circuit 2.

This means that there are two heating circuits, regulated at different temperatures, without a mixing valve or motorisation and with only one regulation.

The Duotherm-System saves on the accessories inherent in this type of installation with a conventional boiler (mixing valve, valve motorisation, controller, etc.) and ensures optimum comfort.
