The Alpha 3, AL910, is the big one in the Hi-Flame Alpha range, a 10kW-plus stove built for heating larger rooms and open-plan spaces. It comes in standard room-heater and boiler versions, and both push enough heat to work their internals hard.

This collection covers both variants. Vermiculite fire bricks for the firebox, ceramic stove glass to the Alpha 3 door, riddling grates and grate bars, baffle plate, and rope seals. Boiler owners, take note that your firebrick arrangement can differ from the dry model, so match to your version.

Stove Spare Parts has supplied Alpha 3 spares for years. On a stove this size the baffle plate earns its money, sitting right in the hottest part of the fire, and it's worth checking every season for warping or burn-through. A tired baffle wrecks efficiency and lets heat straight up the flue. Replace it along with cracked bricks and the Alpha 3 gets back to putting out proper heat.
