effecta lambda ii


Effecta has since 1982 developed and manufactured wood log boilers. Effecta has constantly been in the cutting edge of the development of technology and combustion. Effecta Lambda II is a boiler for the future, which meets the highest requirements in quality, environment, design, combustion and safety. The boiler is tested and approved in EN 303-5 212 Class 5. German BAFA and English MCS is known for the toughest standards in the world, Effecta Lambda II is on both lists with great values, for example 93% efficieny and a CO of only 111mg/m3. Our boilers can withstand comparison.


Effecta Lambda II is available in 35 & 60kW, in order to get the right effect to the right house. To make it convenient for the user the gasification chambers in the boilers are generous. A large gasification chamber leads to fewer inserts and a more convenient heating system. The gasification chamber in Effecta Lambda II is 145 & 195 liters. The least recommended accumulator volume is 1500 & 3000 liter.


Lambda control on wood heating boilers has been natural for Effecta since 2005, and we are Swedens most experienced company in lambda controlled combustion. Today lambda control is a matter of course for many people using a log fired boiler. Effecta Lambda II simplifies your heating by making sure that the logs always burns optimally. With a lambda probe that measures the oxygen in the flue gases, the best possible combustion is ensured. The combustion is done in two steps, first we add primary air to dry and gasify the logs, then the gas is sucked down through the ceramics and then secondary air is added to ignite the gas with a combustion temperature of 1100°C. The boilers two damper motors regulates the oxygen level to provide the best combustion and efficiency. Effecta Lamda II gives you a new experince ond convenience in wood heating. The boiler will always burn optimal without any adjustments and there are minimal of ash due to the clean combustion. Regardless if your loggs are big, small or varying moisture content, the boiler will give you maximum of energy.


Effecta Lambda II is improved in every detail, build to sustain the tough environment a wood logg boiler often endures. The doors and handles are powerful with a locking device that is adjustable. The doors can be mounted on both sides in order to place the boiler in the boiler room. As an option you can choose door cleaning, the heat exchanger is cleaned without you noticing it. This makes the maintenance of the boiler to a complete delight. Every time you open the door to the gasification chamber the heat exchanger is cleaned. Instead of cleaning the heat exchanger every two weeks, it is only needed to be manaully cleaned 2-4 times a year. Open, close, cleaned!


In the control panel on Effecta Lambda II there is a graphic display that gives you total control over the status of your boiler and your heating system. You navigate with ease through the menus, you can for axample see boiler temperature, flue gas temperture, CO2 levels, efficiency and accumulator temperature.  e-burn also controls the heat to the radiators.  As standard you can control one heat circuit, but there is option that allows you to control up to three circuits. All circuits can be controlled by an indoor sensor, outdoor sensor or both. If you want a constant flow that is also a possibility. With a smart control such as e-burn it is very simply for you as a user to have total control over your heating system and boiler.

Effecta Lambda II wood log boiler

Well proven ceramics

Low running costs

The ceramic insert in a Effecta Lambda II was developed as early as 1996. Ever since the same base and core has been used and only small changes has been done to the heart of the boiler. Why change a perfect part? Our ceramic insert will last 8-12 years in average which makes the running costs very low!

Bosch Lambda sensor

German quality at it´s best

Already in 2005 we started to use the Lambda sensor from Bosch in our Lambda log boilers, ever since we have been impresser with the reliability and quality of the sensor. The Lambda sensor monitors the combustion and distributes the primary and secondary air to the combustion from it´s reading. Simple, smart and well proven!

Made in Sweden

Swedish steel, long know how

At Effecta we are very proud to produce our boilers in Sweden with Swedish steel. Sweden has been known for centuries when it comes to high steel quality. Our boilers are built from tradition and know how about materials and design leading to a long life length of the product. 

Prepared for pellets

Future fuel options available

As an option the wood log boilers from Effecta can be bought prepared for wood pellets. At a later stage it is then possible to fit a wood pellet burner in to the boiler and use it as a wood pellet boiler. 


Intelligent controller

In order to achieve the extremely low emissions that the Effecta Lambda II has a intellgent controller is required. Besides the perfect combustion the Effecta Lambda II can also control up to three heating circuits to provide a perfect temperature climate in your home as well as maximum efficiency. 

Well built vessel

Well proven

In the Effecta Lambda II we have gathered all of our knowledge of firing wood logs. Effecta started building wood log boilers in 1982 ever since we have been a innovative company pushing the limits when it comes to efficiency and user friendliness.
