Marshall-Tufflex says its new Commercial Boiler Manager unit ‘can cut 20% (subject to boiler use pattern) off’ heating and hot water bills, and prolong commercial boiler life, ‘without compromising user comfort’.
The system, which is suitable for installation with single and linked pairs of boilers under a common header where boiler output exceeds 30 kW, uses digital microprocessors programmed to reduce unnecessary firing, not only cutting energy bills and CO2 emissions, but also prolonging the lifespan of boilers, ‘simply because they are not working so hard’. ‘Compact, and straightforward for a qualified electrician to install’, the system uses ‘a unique variable thermal response programme’ to manage combi, condensing, and modulating boilers fuelled by gas, oil, or LPG. Electronic sensors fitted to flow and return pipes monitor outgoing and incoming water temperatures, varying system temperature/firing accordingly, and ‘significantly reducing’ fuel wastage caused by temperature overshoot, heat saturation of the heat exchanger, flue losses, and unnecessary cycling. The system can be used with boiler plant managed by a building energy management system.
