Cheap liner: not a good idea





That's what happens with cheap £9.99 liner - it fails and get's ripped out (or fails during fitting by unravelling).
Yes, you can buy cheap chimney flue liner at £15 or less a metre (watch for those ads across the top of the search engines and on well known auction sites): but like everything in life you get what you pay for. Stovefitters do not use cheap chimney liner in their own homes (and good fitters choose a good brand for their customers chimneys).

I don’t want my customers ringing me up in a few years time to say it has burnt through/rotted/fallen apart in their chimney. I want to sleep at night – so I only fit Duraflue which I know and trust and is of a very high quality.


CHEAP CHIMNEY LINER DE-LAMINATES DURING INSTALLATION (and you will never know as it is hidden)

This is what flue liner looks like when it has been dragged around one bend in a chimney (most chimneys have at least one bend): the layers are separating and peeling back. Every part of the liner will pass through a bend in the attic (bends usually in attic or just above fireplace) so this damage will be prevalent along the complete length of your liner. At worst the layers come apart and the liner fails. WITH DURAFLUE CHIMNEY LINER THE LAYERS NEVER SEPARATE AND THE FLUE REMAINS SMOOTH.

DuraflueCheap flue liner can also separate during fitting leaving a length of liner stuck in your flue – TO REMOVE IT YOU WILL HAVE TO BREAK THROUGH INTO THE AREA CONCERNED.
As well as this a smooth flue takes the gases away much more effectively than a flue with “damage ledges” along its length (a good draw on your stove is what you want, very important and anything that hinders this is not good).

CHEAP LINER IS EASILY EATEN AWAY BY THE “NASTIES” PRESENT WITHIN SMOKE

Cheap chimney liner will often fail within your chimney (acids and tar eat away at it) with smoke being released into the cavity between your liner and your chimney wall (from here it will strive to find an exit into your property).

CHEAP LINER MANUFACTURERS: SOME OF THEM HAVE IMPRESSIVE WEBSITES

It really is not difficult or expensive to set up an ecommerce website nowadays

BUT CHEAP LINER IS HETAS-CERTIFIED

Hetas do not compare the quality of liners.

CHEAP LINER MANUFACTURERS AND RETAILERS OFFER AMAZING TOO-GOOD-TO-BE-TRUE GUARANTEES

All liner manufacturers offer an “X-YEAR” GUARANTEE (OR EVEN A LIFETIME GUARANTEE). But read the small print as many will likely have you send them a sample of liner and they will test it and state that you have burned unsuitable fuels (e.g. wood with paint on) and try proving you have not! Even if they do replace your liner (most folks will not want get this far because they do not relish the confrontation) liner producers will NOT pay for all the re-installation costs (time, money, scaffolding, disruption etc.).

DO IT ONCE AND DO IT GOOD.

Do you really want to spend all of this time and energy fitting a wonderful wood burning stove and have liner that is falling apart in your chimney?

BUT THEY THROW IN SO MANY EXTRAS AND IT ALL COMES TO ONE GREAT PRICE!

That’s because it’s often inferior product. You get what you pay for. As a stovefitter I have fitted cowls that last one year and I’m back again because the stainless has rusted through or the spot weld has failed and it’s now lying in the garden and useless. Duraflue cowls (the best in my opinion), as just one example of their fine products, have no exterior spot welds as this is a prime area for failure and they are also use high-grade decent thickness stainless steel.

I CHOOSE DURAFLUE

The liner to use is Dura Flue. It is a premier German design of flue liner manufactured under licence in the UK using German-designed machines. It is a little heavier duty than many other liners. Its main selling point is that the layers do not separate at all: the inner surface remains undamaged and smooth despite being dragged around tight chimney bends.

Cowls, adaptors, vitreous pipe made by Duraflue are superior to almost anything on the market.

You would say all of this wouldn’t you as your company sells this Duraflue! I can fit anything I choose to fit and I can sell anything I choose to sell. I get calls every month from liner manufacturers trying to get me to use and sell their liner. I use and sell Duraflue because, to be honest, I do not want the stress of you ringing up because your liner has failed.

One of our largest competitors (Stoves Online) says this about Duraflue 316 flue liner:

“We sell a good quality liner that does the job very well but we do, occasionally, get requests for a liner that needs to go into particularly demanding situations and for that we’ve always recommended DuraFlue. Duraflue flexible liner is formed by a different process than standard liner, which gives it enormous resistance to denting, tearing, unravelling etc… and is as good at going round bends in the chimney as a standard liner.”

Our customers say:

“The Duraflue 904 chimney liner was very tough and i don’t think a lessor liner would have survived the installation. The pipework wall was twice as thick as the stuff it was replacing” Scott Grady confirmed purchaser Trustpilot verified

“The Duraflue is much better than a previous sample of cheaper flue. (The cheap stuff could not be cut without unravelling in a razor sharp spiral and collapsed easily)” William Whitelaw confirmed purchaser Trustpilot verified

Happy stove fitting,
