Peanut

We have now fitted out Peanut Woodburner bought through Stovefitter’s Warehouse and are very pleased. Everything ordered came in good time and as predicted and as Julian had been very helpful in advising us on what additional parts we needed for our space we were confident we had all we needed. We had a local chap install the stove and he too was happy that all certificates and regulations could be signed off to comply with current safely standards. Thank you for an excellent service - we are looking forward to enjoying our little wood burner for years to come

Flue liner

Really nice product went in a dream as it had some flex but still easy to push through. Service was brilliant needed it for a certain day and it came on that day, well packaged ready to go.

Only had the flue installed for a few months but cannot fault the service and product.

Would definitely recommend to anyone installing a log burner.

Description

About Silvacore Chimney Liner

Wood burning stove

Silvacore is created on a German-made machine imported to the UK. Only two brands are made on this beautifully-engineered machine and one of the two brands is Silvacore (the other is Duraflue). "I have Silvacore in my chimney" (Julian Patrick, author of The Stovefitter's Manual).

A flue liner is not a product you want to fail within just a few years. Silvacore is designed for professional trade-fitters desiring a premium product for chimney lining.

Silvacore chimney liner is created from TWO compressed stainless-steel layers and this unique laminate stays smooth when the product is passed around chimney bends (with a lesser-quality liner the laminate usually comes apart when dragged through bends - allowing acids from soot deposits to enter and later cause corrosion).

904 and 316 are grades of stainless steel. If you are a heavy user of coal/smokeless fuel then one would be advised to ensure that, as a minimum, the inside layer of your liner is 904 grade.
 
 

Specifications

Quality

Silvacore chimney liner is available in three levels of quality:
316 - wood only, light use

316 (15-year guarantee): suitable for non-eco-design stoves, wood-only fuel use, light use. This liner has an inner core of 316 grade stainless.

Thickness 0.9mm.

904 - light to medium, all fuels

MOST POPULAR CHOICE

904 (30-year guarantee): suitable for all stoves and all fuels (including eco-design stoves), light to medium use. This liner has an inner core of 904 grade stainless.

Thickness 0.9mm.

W3G - Heavy use, all fuels

W3G* (lifetime guarantee): suitable for all stoves and all fuels (including eco-design stoves) and heavy use. W3G has a treated double-layer of 904 grade stainless.

Thickness 0.9mm.

Silvacore can be fitted any way up

Unlike most other brands (where the layers separate on bends) Silvacore can be installed any way up in the chimney.


Caution

Slumbering a stove or "banking it up" overnight can shorten the life of the liner. This is because the bad stuff in the gases is not burned off and condenses within the liner. Slumbering is bad for liner, cowl and the environment. Don't do it. Do not mix wood with coal or smokeless fuel (moisture in wood reacts and creates Sulphuric acid). If you insist on slumbering you must choose W3G.


Dura flue silvacore

Only two brands are licensed to use W3G technology: Silvacore and Duraflue. Silvacore is manufacture in the Duraflue factory.

Below are two excellent videos on fitting a liner and then the stove. Note that our Silvacore liner no longer has arrows - it is uni-directional so can be fitted either way. We also generally provide hanging cowl (connects to liner) so the other bits inside the chimney pot in the video are not required.
