Dynamic Energy Products : Saving You Energy

Dynamic Burner Management Unit (DBMU)

How Does It Work?

The DBMU is installed between the thermostat and the burner valve. It alters the firing pattern of the boiler creating fewer but slightly longer burn periods.  The overall effect is to reduce the amount of time the boiler is burning.  For example, 8 burns of 10 minutes in a 4-hour period will be typically reduced to 5 burns of 12.5 minutes, i.e. a 21% reduction.  The analogy is that of a car running a lot of short journeys compared with fewer longer journeys, which results in more efficient fuel consumption.

The DBMU responds to the needs of the building and there is no variation in internal temperature when a unit is fitted.

Is My Boiler Suitable?

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 and up to 2,000 kW will be suitable.

The DBMU will not affect the operation of the Building Management System (BMS), nor will the BMS impact on the DBMU.

How Does It Prove It Is Saving Fuel?

The DBMU uniquely proves its savings in two ways:

BRE Certification LimitedFirstly, 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 Dynamic 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’.  It will hold three such tests in the memory, which can be downloaded into a palm-held computer, producing a record of the savings over 150 boiler cycles.

Payback tables are calculated for each enquiry and issued as part of the quotation.
