Saltfire Bignut 5 Tall 5kW Wood Burning Stove

Saltfire BigNut 5 Tall - EcoDesign Wood Burning Stove with Log Store

The BigNut 5 Tall makes an interesting case. The Peanut range packs high output into a compact body - the BigNut takes a different approach, pairing a 5kW output with a significantly larger firebox in the same 800mm tall, log-store-base format. The result is a stove that heats an average-sized room efficiently, accepts logs up to 370mm long without needing them cut down further, and sits at a comfortable firebox viewing height thanks to the integrated log store beneath. Less about raw power, more about the quality of the experience of using it.

That 370mm log capacity is worth pausing on - it's a genuinely large firebox opening for a 5kW stove, and it makes a practical difference every time the stove is loaded. Fewer splits, less preparation, longer burns between refuels. The cast iron construction at approximately 110kg does the rest - absorbing heat during the burn and releasing it steadily into the room long after the fire has settled, which is exactly the behaviour that makes a 5kW stove capable of keeping a well-proportioned room consistently warm rather than cycling between hot and cool.

The large viewing window and airwash system keep the flame display clean and unobstructed throughout, the integrated log store keeps fuel tidy and immediately to hand, and top or rear flue outlet options handle most installation configurations without adaptation. DEFRA approved, SIA EcoDesign 2022 Ready, running at around 80% efficiency, and backed by a 5-year manufacturer's warranty on registration.
