With more than 60.000 homes are heated with wood burning boilers since 1974, PERGE is a real reference point in the French wood burning boilers market.

PERGE MC CI are high efficiency natural draught wood burning boilers (ex. : MC 5.20 CI : 80,8%). The original hydraulic design of the PERGE MC CI wood burning boilers  provides them a significant competitive advantage.

MC CI : simple and compact

Running without electricity

PERGE MC CI wood burning boilers do not need electricity for running. The boiler temperature controller and the over-heat safety valve are thermostatic devices which work in any circumstances. The anti-boiling quench coil is factory fitted.

A superimposed DHW stainless steel tank to save lot of space

A 150 liters Domestic Hot Water stainless steel tank may be integrated in the PERGE MC CI boilers, without additionnal floor space required.
It is delivered with a thermostatic valve which allows to control the hot water temperature.
It may be fitted at the first installation or later.
An optional 3,5 kW electrical resistance may be fitted to produce hot water during the Summer or when the boiler is off.

A large combustion chamber with easy loading

The refractory cement combustion chamber with a depth of 56 cm allows 50 cm logs. A 30 cm x 30 cm door makes the loading easier.

MC CI : reliable and powerful

A refractory ceramic combustion chamber to avoid dew point and corrosion

In a traditionnal boiler, the walls of the combustion chamber barely exceed the temperature of the water inside (70°C to 80°C), whereas the PERGE MC design utilises a number of tubes cast into a high temperature refractory ceramic combustion chamber.
This design allows the inside surface of the combustion chamber to reach temperature of above 500°C, ensuring complete and efficient combustion and eliminates tar, even for wet wood.
The PERGE patented combustion chamber design protects the boiler pipes from condensation and corrosive flue by-products and prevent corrosion, with the additionnal benefit that even low temperature water from the return is not an issue.
An accumulator tank is not required. A 3 gate valve may be added in order to control the temperature of the heating circuit.

With an accumulator tank for a better comfort

PERGE MC CI are high efficiency boilers. With an accumulator tank, they give all their power with an optimized efficiency without complicated electronic device. It gives a complete comfort for the user as well.

Manufacturer requirements

  • Chimney installations and Ventilation should conform to requirements of the Building Regulations and any approved local laws and all subsequent standards referred to.
  • A flue draught of between 17 and 22 Pa is required when running at rated output.
  • Additional flue pull shall require a draught stabiliser to be fitted to prevent over-firing.
  • Any pressurised system must have a sufficiently sized expansion vessel and a suitable PRV. In addition the integral anti-boiling quench coil must be connected to a suitable mechanisal safety valve.
