With PERGE MC Classique, you are making the choice of a simple and reliable boiler :
The original hydraulic design of the PERGE MC Classique wood burning boilers makes the installation without an accumulator tank possible. It provides a significant competitive advantage to the PERGE MC Classique boilers.
PERGE MC Classique 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.
They include also thermosiphon connections to produce domestic hot water in complete independence.
If the heating installation is designed as a thermosiphon system, they allow an autonomous operation without electricity in total safety.
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.
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. The MC Classique model available since 1984 is always satisfying completly its users.
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.
• 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 13 and 18 Pa is required when running at rated output.
• Additional flue pull shall require a draught stabiliser to be fitted to prevent over-firing.ype
• 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.
