Dynamic Burner Management Unit

A Dynamic Burner Management Unit (DBMU) is installed between the thermostat and burner valve. The unit alters the firing pattern of the boiler creating fewer but slightly longer burn periods. The overall goal is to reduce the amount of time the boiler is burning.

The DBMU is designed to work specifically with gas or oil boilers, both atmospheric and with forced draught burners. It is not suitable for wall hung or low water content boilers. Generally a floor standing boiler greater than 50 kW will be suitable. It does not affect the operation of the Building Management System (BMS), nor does the BMS impact on the DBMU.

The BMU uniquely proves its savings in two ways:

Firstly, it is the only energy saving product whose performance has been independently certified by the Building Research Establishment – Certificate CFP 348. Proved through extensive laboratory tests, the “BRE” tick is unique to the Burner Management Unit.

Secondly, the DBMU is designed to take itself in and out of circuit every 50 boiler cycles. It then compares the fuel consumption when it is in and out of circuit and calculates a “Savings Report”.

These reports are accessed from a lap-top or PC and are an excellent way of proving the savings and displaying them for reporting purposes.

They are by far the most impressive piece of energy saving equipment I have seen, and the savings which they have made are nothing short of amazing.

The impact of DBMU Installations

  • We estimate that the DBMU's installed thus far are saving well over £50,000,000 a year in energy costs.

    This equates to a saving of over 4.65 million tonnes of carbon per year.
