DPX Split Log

DPX Lambda

91 percent efficiencyThe DPX Lambda is a split log boiler gasifying boiler, our top of the range product featuring a Lambda combustion gas sensor. The Lambda sensor provides feedback to the boilers control unit allowing the boiler to automatically alter the combustion environment to achieve the highest possible efficiency, and maximise the gain from the fuel. The Lambda boiler also features the improved tubular heat exchanger and lever arm cleaning mechanism increasing the efficiency and making maintenance and cleaning a simple process.


Utilising the syngas from the gasification process the DPX Lambda range is 91% efficient.


The boilers will often be coupled with a accumulator which is a large hot water storage cylinder. A popular accumulator is the Akvaterm range of hot water storage cylinder range which feature superb insulation properties designed with efficiency in mind.

Suitable for use with radiators or underfloor heating.
