Product information

The Invicta Siam Wood Burning Stove is an efficient and convenient way to heat your home. With French engineering and manufacturing, it offers robust construction and reliable performance.

Extended burning capability

With the Invicta Siam's slow combustion mode, a single fuel load can provide a remarkable 8 hours of warmth without needing more logs or any external help. The stove maintains a bed of hot embers, making reloading and relighting easy when the time comes. This extended burning capability, along with the 12 kW optimal power output, allows the Invicta Siam to heat areas from 65 to 145 sqm.

Intelligent combustion control

Several smart features work together to optimise the Invicta Siam's combustion efficiency. Adjustable secondary air ensures full burning of volatile materials, while protecting the glass from smoke deposits. The clean glass system creates an insulating air curtain along the glass to prevent soot build-up. Post-combustion injected air enables complete destruction of hydrocarbons for reduced emissions. With certified 77% useful and 67% seasonal efficiency, this wood burner achieves seven stars on the Flamme Verte environmental label.

Features & benefits

  • Eight-Hour Extended Burning: The slow combustion mode allows the stove to provide warmth for a full 8 hours without adding more logs or needing external intervention.
  • Adjustable Secondary Air: This protects the glass from smoke deposits and adapts combustion to high draft conditions for optimal efficiency.
  • Clean Glass System: An insulating air curtain along the glass prevents soot build-up and keeps the view of the fire clear.
  • Connectable to Outside Air: An optional kit allows direct connection to fresh outside air, improving combustion.
  • Three-Year Extended Warranty: Register online to receive a free additional three years of warranty coverage.
  • Made in France Guarantee: Certified as produced in France after an independent audit, ensuring quality manufacturing.

Liner Pack & Stove Kits

Direct Stoves - Stove Fitting Kits*
What's included in the fitting kit
  • 1. Black stove pipe.
  • 2. A registration plate is used to seal the chimney opening off from the room preventing dust, soot, dirt and debris falling down the chimney. It also helps to prevent a draft coming down the chimney. We supply a standard 800mm x 400mm galvanised steel register plate with all our stoves. You will simply need to cut the plate to size to fit into your chimney opening.
  • 3. We also provide you with a single stove glove that you can use for stoking the fire and adding wood without the risk of personal injury.

*Only available for wood, multifuel and gas stoves. Excluded for the following which do not need these items: inset stoves, electric stoves, flueless and balanced flue gas stoves and outdoor & garden products.

Optional Extras.
Carbon Monoxide Detector:

Due to an update to Building Regulations it is now law to have a Carbon Monoxide alarm present in any room with a solid fuel appliance:- The Building Regulations 2000 Approved Document J (2010 Edition) '2.34 Where a new or replacement fixed solid fuel appliance is installed in the dwelling, a carbon monoxide alarm should be provided in the room where the appliance is located.'



Flue Liner Packs:
The flue liner pack consists of; a flue adaptor, which connects the stove pipe to the flexible flue liner, Dura Flue flexible flue liner (this will have a relevant diameter to the outlet size of the stove and 316 Grade) cut to the required length and a pot hanger rain cap, this supports the flue liner from the top of the chimney and also acts as a bird guard and rain cap.

Stove Pipe with Door:
A stove pipe with door or access point, allows the chimney to be swept through the pipe itself.

Stove Glass Insurance:
If you select to take out our stove glass insurance this covers your stove glass for the time period you select.
If your glass breaks within that time period we will send you a replacement piece of glass regardless of the reason the glass broke. All we will ask is that you send a picture of the broken glass.
The insurance only covers you for one replacement piece of glass. It doesn't cover you if you break the replacement piece of glass.
All stove glass is covered during delivery and any glass broken in transit to you will be replaced free of charge, without affecting your stove glass insurance.

Delivery Info

Free 1 Man Delivery – For Full Details Please See Delivery Information

Our "Free Delivery" is a one-man service. The goods will arrive on a lorry that is about the size of a fire engine. (Please let us know in advance if you have restricted access or other local issues that could affect delivery).

The lorry has a tail lift that allows the driver to get the item(s) off the vehicle. The order will be packed and secured onto a pallet and the driver will have a pallet truck. He'll be able to wheel this as close as possible to your property. The pallet truck can only be wheeled over a finished surface so it's not possible to wheel it over a gravelled drive, steps, steep slopes for example. The pallets are normally about 1m wide so this is the minimum width gate they can fit through. Please note that the driver is not insured to unpack or carry the item(s) into your house.

Fitting Kits and Liner Packs might arrive separately by courier delivery on the same day unless specified/requested in advance. An email confirmation will be sent if this is the case.

If the goods are showing 48hr delivery, then this is the quickest time we're able to deliver these items (We do not deliver at weekends). You'll be asked to select a delivery date when purchasing the goods. Please note that if you live offshore these dates do not apply as it will take us slightly longer to get the goods to you and we will contact you directly.

Please note that it is an all-day delivery service which is generally from 9 am – 6 pm Monday to Friday. Delivery Depots, if they have the facility, will text in advance but as the vans do multiple runs a day you might not receive a text until the afternoon if this service is available.

Due to current pallet network pressures mainly due to driver shortages we cannot guarantee delivery on your chosen day but will do our best to communicate this as soon as we are made aware by the carriers.

PLEASE NOTE THAT WE STRONGLY ADVISE THAT YOU DO NOT BOOK ANY CONTRACTORS, PLUMBER’S, OR FITTERS UNTIL YOU HAVE RECEIVED YOUR GOODS AS UNEXPECTED DELAYS CAN OCCUR.
