A Mind @ Play

We’ve had a pellet boiler installed at these premises for a number of years, and whilst generally pretty efficient and reliable, recently there were some problems which couldn’t be solved with the usual panache of just hitting it and telling it to work. The boiler, a 15 kW Künzel PL15 , had got stuck in a de-ashing cycle and would only intermittently fire up before returning to this cycle. Unfortunately, the firm which installed the boiler had in the meantime gone out of business, and our only option was to send for an engineer from a neighbouring county, which took several days, before the unit could be looked at. It turned out to be a problem with the microprocessor controller, the piece of kit which maintains the boiler’s high efficiency, though obviously beyond our capabilities to solve without sufficient technical knowledge (even the engineer who appeared on site had to call back to base for instructions that weren’t included in his handbook).
