Thank you for your question.
We would recommend you have the property surveyed by a Hetas registered installer before purchasing any stoves or liner.
They will be able to tell you if you need a chimney liner and how much you will need.
Our liner packs can be purchased from the dropdown options when ordering your stove. The liner pack contains the requested length of 316 grade stainless steel liner along with an adapter to fit the stove pipe and a raincap that fits in the top of the chimney pot.
If you require 6 Metres of liner the current price would be £183 inc. VAT. (11/09/2017)
