Pellet stoves occupy a sensible middle in heating-appliance economics: more machine than a space heater, less project than a fireplace build. The invoice has four lines; here’s what drives each.
Line 1: the appliance
Hopper capacity, BTU output, and control sophistication set the tier, entry units heat a room; flagship units with big hoppers, programmable thermostats, and self-cleaning cycles heat small homes. Brand matters here more than in most categories: parts availability and auger/blower quality separate the decade-runners from the disposables. We’ll steer honestly, the pros-and-cons guide covers the ownership reality.
Line 2: venting, smaller pipe, its own rules
Pellet exhaust is fan-driven and cooler than wood smoke, so it uses dedicated pellet vent (typically 3-4 inch), which can run horizontally through a wall with a short rise, the routing freedom that makes pellet installs flexible. Cost scales with route: straight-out-the-wall is the base case; vertical runs, extra elbows, or routing up an existing chimney (with a liner adapter) add per-foot and per-fitting. The venting options guide maps the choices.
Line 3: hearth and clearances
A non-combustible floor pad sized to the listing, wall clearances per the manual (modest, pellet shells run cooler than wood stoves), and any wall shielding where placement is tight. Usually a modest line; occasionally the placement-decider in carpeted rooms.
Line 4: electrical
Auger, igniter, and blowers need a nearby outlet, existing outlet: free; new circuit: an electrician line item. Worth asking about surge protection and, for outage-resilience buyers, battery-backup options, pellet’s grid dependency is its one resilience gap.
