The Weishaupt range of Digital Burners with Electronic Compound Regulation and Multiflam technology, for oil and gas burners, giving them a level of efficiency and emissions that arguably cannot be bettered by our competition.

Looking at  burners on the market and fire them at high fire, there is nothing much to choose between them on combustion efficiency perhaps 0.5 to 1% CO₂ but as one starts to turn the burners down to low fire you separate the burners on their performance.  In this situation when approaching a 2:1 turndown you have burners  having to add unacceptable amounts of excess air to stabilise their flame that they have residual O₂ levels of 5 to 10% showing a decrease in CO₂ of some 3 to 5%, as they turndown further this O₂ figure becomes larger with the burner flame being totally unstable.

The point to strive for is to keep the CO₂ as high as possible, the residual O₂ level as low as possible by achieving this, the combustion is as close to Stoichiometric as one can leave the burner,  the next point is to hold this combustion condition as near as possible through the turndown range of the burner.

This is the basis on which Weishaupt operate, once this has been achieved, the burners combustion gases are passed through the boiler as slowly as possible allowing the maximum time for the flue gases to transfer heat to the water in the boiler, resulting in maximum efficiencies by lowering the flue temperature.

With the use of variable speed drives for the burner fans and O₂ Trim to maximise combustion efficiency and have in the package a proper control system, result of which has shown saving on fuel bills of up to 20%  and in certain cases higher, in certain cases the savings have been in the region of 27%.

With Weishaupt burners fitted to a good boiler having a DIN standard combustion chamber, it is  expected to achieve at high fire 10.5% CO₂ @ 2.5% O₂,  at low fire (possibly 4:1 turndown this is dependent on boiler back end temperature) something in the region of  9.5 to 10% CO₂ @ 3 to 4% O₂. With O₂ Trim these O₂ figures would drop to 1.2% at high fire and 2% at low fire.

When we look at these figures with some of our closest competition at high fire they would show 9.5 to 10% O₂ and 3 to 3.5% O₂,when looking at low fire many can only turn down to 2:1 showing CO2 figures in the region of 7% and O2 figures in excess of 5% transferring heat out of the boiler to the flue due to extravagant amounts of excess air being used to stabilise the flame.
