Lambda Log Boilers

Background

Effecta Lambda is a Range of 25, 35 or 60 kW Log Boilers

Effecta’s Lambda’s range of modern biomass log boilers have large fireboxes and can take logs up to 500mm in length.

The standard large grate and highly efficient combustion mean that you don’t need to refill the boiler very often.

Key Features

  • Heat outputs 25, 35, 60kW.
  • Lambda controlled with automatic dampers.
  • High efficiency and low emissions.
  • Available with side mounted (60kW) pellet burner.
  • Also available with front mounted (25, 35kW) pellet burner.
  • Large fire grate 100/145/195 litres.
  • Easy for anyone to use.
  • Adjustable and reversible doors.
  • Optional; cleaned when door opened.
  • Cooling coil.

Log Gasification Technology

Logs are gasified in the loading compartment at around 600oC. As the hot gases pass down through the ceramics, secondary air is introduced and the gasses are burned at higher temperatures of 1,200oC.

Lambda Pellet Burner Option - Logs and Pellets

Side mounted wood pellet burner

If you decide wood pellets are a more convenient fuel type for your property, a side mounted wood pellet burner can be installed to give heat outputs of 25kW or 35kW. A front mounted wood pellet burner can be fitted to give heat outputs up to 60kW, giving you choice and flexibility.

Attractive with Robust Design

The Effecta Lambda log boiler is a simple Scandinavian design, a look to complement any boiler room.. Effecta can offer lower installation costs by completing and assembling their boilers in the factory, reducing costs for you.

MCS Accredited

All Effecta Lambda biomass boilers below 45kW are MCS accredited and therefore suitable for your Domestic RHI project. View the relevant MCS pages via the links below;

Effecta Lambda log Boiler; 25kW

Effecta Lambda log Boiler; 35kW

MCS approved - Made in Sweden - 93% efficiency

Seriously Low Emissions

Accreditation into MCS requires emissions below 30g/Gj Particulates (PM) and 150 g/Gj of Nitrogen Oxide (NOx). All 3 of the Effecta Lambda log boilers have emissions significantly below these limits, making the Effecta Lambda range ideal for either Commercial or Domestic Renewable Heat Incentive projects..

Boiler PM NOx
Maximum Emissions 30 g/GJ 150 g/GJ
Effecta Boiler Emissions    
Effecta Lambda Log Boiler 25 9.7 g/GJ 138 g/GJ
Effecta Lambda Log Boiler 35 13 g/GJ 91 g/GJ
Effecta Lambda Log Boiler 60 19 g/GJ 80 g/GJ

 

Always Use an Accumulator Tank

Effecta Lambda log boilers are used in  in conjunction with an accumulator tank. Energy stored in the accumulator tank is then ready to be used when needed. Depending on which boiler is the right fit for your project the accumulator tank should have a 1,000, 1,500 or 3,000 litre capacity.

The Perfect Amount of Air

Achieving the highest level of combustion efficiency is a major task as anyone with experience in log boilers know but the Effecta Lambda log boilers are equipped with a lambda sensor, which ensures consistency of firing, with optimum combustion and the lowest emissions.

Lambda sensor

Intuitive Controller

Effecta Lambda simplifies your wood firing substantially. The Lambda sensor, situated in the flue gas channel, indicates to the boiler  how the combustion is running. The touch screen  panel is easy to use and displays temperatures, accurately calculated to within a degree of efficiency.

Highest Efficiency and Best Combustion

The air inlet dampers on the front of the boiler are optimised with motors to give you excellent combustion and highest efficiency possible.
