Product Description

Vedolux Lambda 350

Wood Gasification Boiler with Lambda control

Advantages of the Vedolux Lambda Models:
  • Firewood burning with ultimate efficiency
  • Easy to use controler
  • Accomodates 20″ logs
  • Simple boiler tube / flue pipe clean-out design

Here are some differences between this series of boiler and the non-lambda fan models like the Vedolux 30,37 and 55.

Vedolux Lambda 350 boiler works through reverse combustion with the help of a suction fan, but in addition a lambda sensor, also known as an oxygen sensor is installed in the boiler flue that constantly analyzes how the boiler is burning by checking the proportion of oxygen in the exhaust. Then in real time the control makes small corrections to the air mixture to enable this boiler to reach outstanding efficiencies.

Vedolux 350 Quick Facts

The combustion chamber holds approx 3 cu.ft of firewood and accepts wood up to 20″ long.

When properly used and maintained the Vedolux 350 boiler has an output of around 35 KW or 120k Btus per hour.  This boiler tests resulted in 93% efficiency when tested by the Swedish Test Institute. The test protocol is the standard for euopean manufactured wood boilers.  The efficency can only be compared to other similarly tested products.  Most USA tests use the “higher heating value” of the fuel vrs the european standard that uses the “lower heating value” of fuel. The resulting efficiency value would be lower if tested using the US  “higher heating value” formula.

All flue pipes are cleaned through a door located on the front of the boiler. Rounded flue pipes are easily brushed out keeping soot and deposits from accumulated in missed corners.  Because it is so easy to sweep it will get done, keeping your boiler burning efficiently – saving you time and wood!

Storing heat with an accumulator tank

The Vedolux 350 must be installed with an accumulator tank. The accumulator tank stores the heat between the burning cycles. Any heat not used during the regular firing of the boiler will be availabe for later use.

The volume of the accumulator tank(s) should be dimensioned to suit the size of the house and the output of the boiler.  395 gallons of water storage is the minimum needed to accommodate the output the Vedolux 350. This boiler is also  available in 45Kw and 65Kw outputs. More specs can be found in the manual download found below.
