Our wealth of experience means that Pembrokeshire Stoves can confidently give you advice on a number of home heating and insulation topics. We thought we’d outline some useful advice here, but if you would like advice on something not mentioned here, we can definately try to answer your query.


Choosing a stove

Stoves are not all the same. There are considerable differences in efficiency, ease of use, serviceability, longevity and cost. Choosing the right stove is an important starting point. Just some of the things to consider before asking for advice include: Will you have a supply of dry wood all year round? How often are you likely to use the stove? What proportion of the overall heating will it provide?

Installing a stove

There are three main approaches to installing stoves

  1. The most common due to its relatively low cost is to reline an existing chimney with a double skin flexible stainless steel liner. This system is not a permanent solution. The liners have a life expectancy of anywhere between 10 and 20 years depending on the grade and thickness of liner, fuel used (anthracite or wood) and the way the fuel is burnt.
  2. Relining an existing chimney with pumice sections or solid 1mm stainless steel rigid pipe. This can be relatively easy in chimneys that are very straight or large enough for a person to climb inside (e.g. an inglenook). The pumice sections should in theory out live the house. The stainless steel as long as it is insulated and the correct fuel is burnt could easily last more than 65 years. The stainless rigid sections are easier and less expensive than pumice because they are thinner and lighter.If a chimney is winding and / or too small to climb inside then the only way to re-line using pumice of rigid sections of stainless steel is to unstitch the wall along most of its height. This can be expensive and disruptive, but does provide one of the most long term solutions.
  3. The other type of pumice system is sectional free standaing DM system which can be very cost effective, and outlast all other types of liners.

  4. Using stainless steel insulated twin wall pipe is one of the only options if there is no existing chimney or the existing chimney is in filled or in the wrong place. Typically lasts much longer than the 15 year guarantee, but can be damaged prematurely if incorrect fuel is burnt or it is exposed to intense chimney fires. More expensive than relining existing chimneys with flexible liner or straight / accessible chimneys with rigid sectional liners. Not as expensive as unstitching a wall.
  5. We at Pembrokeshire stoves are qualified to install all of the above flue liner systems.

We can help you

chose the stove that will serve you best, rather than the one which would bring us most profit.
chose the most long term and efficient flue system.
get the best out your stove by giving practical demonstrations on burning fuel and lighting the fire.


Avoid poor quality flexible liners because the cost of changing them when they fail will far outweigh the small amount saved at the time. We use what we believe to be one of the best flexible liners on the market.

Where necessary insulate flue systems to ensure the liner lasts and stove runs more efficiently.
