Fuelstretcher has developed a patented algorithm for enhancing boiler efficiency.
Fuelstretcher's controller enables boilers to run at a lower temperature, especially during the shoulder (spring/autumn) heating seasons. This is carried out by measuring the flow and return temperatures on the primary heating circuit. It effectively infers weather compensation, and is self-learning. Current sales are focused on the commercial market, where the company achieves annual sales in the region of £250,000. Fuelstretcher intends to develop a product Ð both manual and automatic Ð for the domestic sector. ROI metrics are very favorable, and the product will be ideally suited to the upcoming Green Deal initiative. The technology can also be applied to chillers and steam calorifiers.
