About the Firewire

Three different sizes to fit every fireplace recess

During the winter of 2018/19 Stovefitter's went in search of a modern, large screen, Ecodesign stove that we could retail between £599 and £799. We tested numerous models and it was the Firewire range that you now see that came out on top. The Firewire is a wood-only stove with a large viewing window and simple yet effective single control.

When we tested the Firewire we were particularly impressed by how clear and clean the glass remained - like new after five full working-days of heating our office in North Wales. A cleaner glass during testing we have yet to find even amongst £1000+ models.

Firewire is only available from Stovefitter's - a range of high-quality products at a very reasonable price point.

Following our five weeks of testing (five days a week, eight hours per day) we are confident in our verdict: there is no finer stove at this price point on the market today. Arran (Stovefitter's Sales Manager) has just installed the Firewire in his new house in North Wales (he has been without fire for a while so is super excited). Due to this Arran is your man for a detailed analysis!

Note that the Firewire stoves require 40cm of hearth in front of the stove (big glass and high heat output).


Three stoves, all 5kW. Three widths to suit different fireplace dimensions.

400mm: Portrait
450mm: Landscape
500mm: Large

Firewire Curve

The Fire wire Curve is also available. The Curve has a curved door (hence the name) and can be found here

Priced a little higher (£100) for the curved door (glass not curved, just door).


This stove is certified as Ecodesign compliant (has passed the new and stringent 2022 regulations).


This stove can burn wood in a Smoke Control Area (most towns and cities are Smoke Control Areas).

Julian's thoughts

There are a few stoves on the market worth buying at this price point and the Firewire is certainly fighting it out at the top of the list. An excellent stove.


Single Control

One control automatically adjusts output and airwash (airwash keeps glass clean). Very user-friendly (and therefore perfect for holiday homes.).

Control slides in and out.

Stovefitter's would rather you go off the top of this stove for best performance (off the top always best with modern high-performance stoves).

Satisfactory Service, great website
Apologies. Peak season +Covid = huge volume of calls/enquiries/sales. We are all pretty exhausted and have long backlog of people wanting to chat over the phone and it is impossible at moment. Texts/emails although frustrating for some, allow us to actually offer a semblance of giving succinct advice. QUICK QUESTIONS TEXT 07520635388 Kind regards, Julian Patrick

Which fitting pack for my liner? Advice here

400: 30cm x 34cm
450: 34cm x 30cm
500: 38cm x 38cm


Flue size

5" (125mm) collar top or rear
Can be installed with a 5" or 6" chimney liner.

IMPORTANT NOTE: STOVEFITTER'S DO NOT RECOMMEND CONNECTING TO THE REAR OF MODERN ECO DESIGN STOVES. Much better for performance to go off the top as this avoids puffs of smoke in room when refuelling.

External air NO

No, this stove cannot be fitted with an external air kit. Usually this option is not relevant unless an air vent is required and the property owners are aiming for an airtight space.

Air vent advice here

Body and door

Steel 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.


Note that 400mm of hearth is required in front of the glass of this stove (as opposed to the usual 225mm as stated in Building regs)

This stove can, if sited outside of a fireplace recess, be sited on a 12mm thick hearth.

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.

400 Model Distance to combustibles REAR: 250mm

Prior to purchasing any stove download the installation manual to check that manufacturers do not have any additional requirements.

Julian's thoughts

There are a few stoves on the market worth buying at this price point and the Firewire is certainly fighting it out at the top of the list. An excellent stove.

The others worth looking at under £700? Flavel Arundel, Hamlet 5 SC, Peanut 5, Saltfire ST-X5.
