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).
Unfortunately there appears to be precious little information out there on the web. I spent some moments trying to find descriptions of problems similar to ours, or find a support forum for users of equipment such as ours where we could perhaps get some feedback, without success. That could of course come more as a result of my Googling skills than anything else. Do you know of any sites, forums or otherwise which deals with pellet boilers and their ilk? If not, is there enough call for one to be set up?
