Absolutely Awesome! Saltfire Peanut 5 Tall

I have never owned a wood burning stove before, and after much googling of all alternative types of solid fuel stoves, I finally settled on the Saltfire Peanut 5 Tall to self install in my workshop. I had considered the Peanut 3, but on Julian's recommendation of bigger is better I am glad I went with the slightly larger model!
I had quite a small space to fit the stove in so the dimensions of the Peanut 5 Tall were ideal and with such a large firebox and telly window its feels like a much bigger stove, and makes for great viewing
The stove is very controllable, and works flawlessly and efficiently giving out loads of lovely heat. having the log store underneath is also great if lacking space for a log basket.
The paint does give off fumes for the first 5 days or so, and I was initially worried thinking that this was smoke coming into the room and that maybe my flue did not have enough draught, but I was assured by Saltfire that this was just paint fumes and it would pass in a few days. (So don't panic if this happens to you, its a normal paint curing process!) I just opened the windows and doors, which was not a problem.
Due to my narrow space and distance to combustible materials, I built a surround using super Isol, calcium silicate boards (still to be finished) as recommended by Soliftec in their pdf for fitting a stove on a boat.
I can highly recommend the Saltfire Peanut 5 Tall, and I will buy again from The Stovefitters Warehouse without hesitation.

Excellent service and fantastic website

The Stove Fitters Warehouse website was invaluable while we were choosing a woodburning stove. The descriptions and measurements gave us all the info we needed and the pages that explain about installing the stove have been invaluable. Our Peanut 3 and associated bits and pieces all arrived on the correct day even with the problems of the pandemic. We've not been able to install it yet as Christmas got in the way, and all the local tradesmen are busy for months. We would have preferred to have been able to buy a 4 inch flue to go with it.

Saltfire Peanut stoves are the fastest selling stoves we have ever launched and deservedly so. Cast iron and contemporary - love it. Fast Flame is just great.

About the Saltfire Peanut 3

Saltfire Peanut 3

The Peanut 3 shares the contemporary design of the rest of the Peanut range and is the smallest in the family. As with the other Peanuts it is made of cast iron and is durable and long-lasting - all wrapped up in a compact body that could well give the Salamander Hobbit a run for its money.

As with all Peanut stoves this model has Fast Flame technology - lighting and re-lighting fires just got a load easier.

All Peanut stoves have Fast Flame to make re-lighting a small bed of embers easy peasy. Read more on our Peanut 5 page.

Output & Fuel

Wood-only (can only burn wood)
Nominal 4kW. Max. 4.4kW

This stove will run happily at 2kW - 4.4kW depending on fuel load. Note that running the stove at a higher fuel level than that specified in the manufacturer's manual may cause degradation of stove innards (firebricks, baffle etc.) although these are replaceable (and repairable with beige fire cement).

Eco Credentials

This stove meets and exceeds the new 2022 Ecodesign regulations

This stove is approved by DEFRA to burn wood in a Smoke Control Area


82.7% (as a rough guide 82.7% of heat goes to the room with 17.3% going up the chimney).

Don't overthink efficiency. 75%-85% is fine and90%+ efficiency may not work so well on shorter or difficult chimneys.

External Air

No, this stove cannot be fitted with an external air kit (draws air from outside via pipe direct to stove). Usually this option is not relevant unless a room air-vent is required and the property is airtight (by design or choice).

Air vent advice here

Body & Door

Cast -iron stove (5-year body guarantee) with cast-iron door

What to buy steel or cast-iron? Do not overthink. Steel heats fast. Cast-iron takes a little longer but retains heat longer as fire dies.


Hearth thickness: minimum 12mm non-combustible material (can include floor thickness).

If in a fireplace recess, a full 125mm thickness constructional hearth is required. This will usually be in place as part of the recess design.

Air Gaps

Distance to combustibles SIDE: 550mm

To non-combustibles there are no hard rules but, around the stove, a 50mm minimum air gap is recommended to brick/stone. This to be increased to 100mm for rendered or boarded surfaces. Prior to purchasing any stove download the installation manual to check that manufacturers do not have any additional requirements.

Delivery Promise

We offer 14 days from delivery to report any courier damage to your stove. If a stove is damaged by the courier we will replace or refund as desired.


Manufacturer's Guarantee

The manufacturer offers a 5 year body guarantee


Why do we sell glass insurance (pre-ticked box close to ADD TO CART button)? Because glass is classed, in the stoves industry, as a consumable item and not covered under ANY guarantee by any manufacture for any reason whatsoever. If it breaks or cracks on day one or day twenty it is not covered. If the inside of the glass goes cloudy or gets any kind of surface coating or etching then it is not covered (it will be to do with what you are burning according to manufacturers and glass makers). Glass usually costs £30-£60 plus postage but can be more on higher end models.


Defra-approved or/and Ecodesign stoves are designed and thoroughly tested before being allowed onto the market and every stove sold is identical. In the rare event a stove does not perform as well as expected it is always down to the installation, the chimney or circumstances unique to the property (pressure imbalances caused by local conditions, down drafts etc.). Here at Stovefitter's we have taken stoves back on a number of occasions for testing on our chimney and in every situation the stoves performed as expected (we may of course find a faulty stove one day but never as yet). We may, at our discretion, take a stove back once it has been used and in this situation a 50% refund would be provided (stove would be sold as second hand). We would, however, offer a 33% refund on a replacement stove.


We will happily strive to match any price you may have from any other supplier as long as the other supplier has it in stock.
Offered an "ex-display" or "shop soiled"? We will strive to offer you a new stove for the same price.

Already have a chimney? You need 1. Stove 2. Liner 3. Fitting Pack 4. Chimney closure plate (Hardiebacker board from Builder's merchants or galvanised sheet).That's it!
No chimney? Check out our shed kits or let us design your clip-together chimney design - easy peasy.
