ConversionSizeAndSpeed
Smoothbrain
Lets you configure the input size and conversion speed of building pieces like the smelter, windmill and charcoal kiln.
Is there a Valheim mod to speed up smelting and crafting?
Work out which half of the wait bothers you. If the process itself is too slow or holds too little, Conversion Size & Speed and BetterSmelting change capacity and speed. If the problem is walking back to reload coal and ore, Automatic Fuel and LazyVikings feed the stations for you.

The details
Conversion Size & Speed is the straightforward numbers mod, and it is broader than its smelter reputation suggests. It configures input size and conversion speed for smelters, blast furnaces, windmills, charcoal kilns, hot tubs and spinning wheels — and, notably, for conversion pieces added by other mods, so it keeps working when you add a modded station. It also adds a hotkey to fill everything at once, which you can disable by clearing the key, and it can be installed on a server to enforce the configuration.
BetterSmelting is the option to reach for when you want per-structure control and published ranges rather than one multiplier. Its documented smelter defaults are 10 ore and 20 fuel, both adjustable up to 200, with a speed multiplier from 0.1 to 10.0, and the blast furnace has its own equivalents. It can also allow all ore types in the blast furnace, permit alternative fuels such as wood and surtling cores, and add a Shift+E shortcut that dumps valid ore or fuel straight from your inventory. Settings are server-synced. Its author has tagged the package as AI generated on Thunderstore, which is worth knowing when you choose between it and the older, more widely used option.
Automatic Fuel attacks the other complaint: the trips. It refuels torches, campfires, hearths, windmills, spinning wheels, kilns and smelters, pulling from nearby chests or from items on the ground, with documented default ranges of about 10 metres that you can tune separately for fuel and ore. Useful details live in its config — leaveLastItem stops it emptying a chest completely, distributedFilling spreads fuel evenly across many stations instead of filling the first one, and restrictKilnOutput stops feeding a kiln once you have enough coal.
LazyVikings is the broader automation of the two and covers more station types: kilns, smelters, blast furnaces, spinning wheels, windmills, beehives, sap collectors, fermenters, eitr refineries, cooking stations, ovens, fire pits and other light sources. Its distinguishing option is direction — each station can be set to auto-fuel only, auto-deposit its output to nearby containers only, or both. Auto-deposit is the half Automatic Fuel does not cover, and it is what turns a smelter row into something you never visit.
Do not stack two mods that feed the same station. Automatic Fuel and LazyVikings overlap heavily and both patch fuelling, so choose one; pairing a feeder with a speed mod is the combination that works, since they change different things. Both feeders and both speed mods use ServerSync, so on a server set the values there and let them propagate rather than having each player configure their own.

Related questions
- Can smelters pull ore from chests automatically?
- Not in vanilla. Automatic Fuel and LazyVikings both add feeding from nearby containers, with a configurable radius. LazyVikings can additionally deposit finished output back into containers.
- What is the difference between a speed mod and an automation mod?
- A speed mod changes how fast a station converts and how much it holds, so you wait less per batch. An automation mod leaves the speed alone and removes the loading and unloading trips. If your smelter row is idle because nobody refilled it, the second one is what you want.
- Do these work with stations added by other mods?
- Conversion Size & Speed states it covers conversion pieces added by other mods. The others list the stations they support explicitly, so check that list if a modded station is the one you care about.
