Frequently Asked Questions

What size of stove do I need?
The way to calculate size of stove required for the room is as follows:
Length (m) x width (m) x height (m) / 14 = output (kw)
Can I still have a stove if the opening in my fireplace is only 16”?
Often stoves can be fitted by ‘digging out’ the opening to enlarge it to allow a free standing stove to sit in the recess (fully or partially). Alternatively you could fit an inset stove which will slot into the existing opening or extend the hearth out the front to allow the stove to sit out.
Why do I need to get a flexi liner even though I have a clay liner?
We only fit stoves with a flexi liner for a couple of reasons. Firstly the stove works better when fitted with a liner as the diameter is usually the same as that of stove outlet so it allows the smoke to rise directly out the chimney rather than cooling down before it gets to the top. Secondly it is very difficult to check the integrity of an existing chimney so there is far higher risk of a house fire without fitting a liner.
I don’t have a chimney – can I still have a stove?
We can install stoves where no chimney is present with a twin wall flue system either inside your property going through ceiling above or out the property wall and up the external wall. The twin wall pipe is insulated keeping the outside of the pipe cooler than the inside meaning the stove can be fitted closer to the wall than by fitting with single wall pipe.
What type and size of hearth is required?
There are a number of variables to consider when choosing a hearth for your stove to sit on. The hearth needs to have 300mm in front of the stove so it depends on which stove you go for.
Do I need an air vent with my wood burning stove?
If the stove has a rated heat output of over 5kw then yes you do. Some new build properties require an air vent regardless of output size so always check.
What is the difference between a wood burner and multi fuel stove?
As the name suggests a wood burner can burn seasoned wood only and the air for combustion comes from above. A multi fuel stove can also burn smokeless coal and peat and often has more controllability than wood burners by having more than one air vent.
What is the efficiency on stoves?
Most stoves have efficiency ratings around 75-85% compared to 25% with open fires and 50% with gas. As well as fitting a liner we always insulate with vermiculite which keeps the heat in the property instead of escaping.
What is the difference between steel and cast iron stoves?
Cast iron takes longer to warm up but will usually radiate heat more evenly and hold their heat for longer after the fire has gone out. Cast iron stoves tend to be heavier with more patterns on the design than steel stoves. Originally steel stoves were less expensive and sophisticated than cast iron but that is not necessarily the case nowadays as many manufacturers use a combination of materials to make a high quality appliance which is both stylish and durable.
What does DEFRA approved mean and is it relevant?
This type of stove allows you to burn wood only in a smoke controlled area however it is not relevant in this part of Scotland.
Who are HETAS and do I need a HETAS certificate upon completion?
HETAS originated as the "Heating Equipment Testing & Approval Scheme". They are the governing body of solid fuel domestic heating appliances, fuels and services and are responsible for the registration of competent installers and businesses in some parts of the UK. Although our fitters have been HETAS trained it is not a requirement in Scotland to be registered and we can provide our own installation checklist if required upon completion.
Will you fit a stove I have sourced elsewhere?
In order to provide proper advice and a full guarantee we usually only fit stoves we supply. We stock a wide variety of stoves and are not tied to any particular brand so can offer honest, impartial advice to fit your individual needs.
Why is the glass on my stove going black?
Most modern stoves are clean burning and keep the glass clear when on. Sometimes however the glass can go very black and it is often caused by burning wet wood (over 20% moisture content). We also find if the stove is turned down a bit too much the glass will blacken quicker too and this can usually be cleared by burning hot with dry logs.
My firebrick has cracked – can I still use my stove?
Over time and use firebricks will crack and this is usually ok to use in the short term until you get a replacement but if it starts to crumble stop using until replaced. We can cut these as required for most stoves or order them in for non-standard bricks.
How often should I have my chimney swept?
We usually suggest getting your stove serviced once per year but some people require it more or less often depending on how much it is used and what is burned on it. We provide an annual stove service during the spring and summer months to customers who we have fitted stoves for and as well as cleaning it out we check rope seals, cement, firebricks and baffle.
