Simpler than ad clips: store → feed → burn pot → heat exchanger → ash box. The controller holds the output, but dust and poor pellets still need attention.
Path of the fuel
From the silo or bag hopper, an auger or suction system feeds the pellet into the combustion chamber. There it burns on the grate or in the retort. Heat goes into the heating water, ash into the box.
What residents notice
Quiet pump and sometimes auger noise, occasional emptying of the ash box (depending on ash content), dry fuel required. Not «forget for five years», but also not daily wood feeding.
Comparison
Compared to gas, the automation is often simpler with gas. Compared to firewood, pellets win on time. Estimate costs roughly in the comparison calculator — that's an example order, not your supplier's tariff.
