Frequently asked questions
How often should I have my chimney swept?
We advise that you should have you chimney/flue swept at least once a year.
Do I need a sweep if I have a liner installed?
You should have your chimney swept even when you have a liner installed!
Why does my glass go black on my stove?
It's likely down to burning wet/damp wood and/or improper usage of your stove controls.
Will a Chimney Sweep make a mess?
At Embers we use the best equipment available with quality sheets and equipment is unlikely we will make a mess. However if your chimney/flue has not been maintained for a number of years it is a possibility. Please let us know this when booking.
Will my stove warranty be invalid if I don't have my stove swept and serviced?
It is highly likely if you make a claim for any reason and your stove and chimney have not been maintained that your insurance maybe invalid.
Does it cost for a Survey?
Surveys are free if you live within 10 miles of our address if not then a small fee will be charged.
Will I need to have my chimney lined?
This will depend on the current construction of your chimney. We assess each job individually. In many cases it is unnecessary to line the chimney. For example if you have a 1970's house you will more than likely have a concrete block liner that if in good condition, should be adequate for your stove. If you have a large brick chimney, it is often advisable to line it. This increases the draught, which in turn makes your stove work better and lowers the risk of tar and soot build up (which can cause chimney fires).
Do I need ventilation?
If you need a stove over 5KW in output then it will be necessary to have a permanent vent in the building to assist with flue draught and to make sure the fire has enough oxygen to burn safely. Anything under 5KW can be installed potentially without need for ventilation in properties built before 2008
What size Wood Burner should I have?
It is important to have a stove that is the right size for the room it is going into. Too big can be just as bad as too small. It is often better to have a smaller stove working hard than to have a larger one that is just chugging away.
To help make it simple measure your room (m) WxLxH divide by 14 giving an average output required.
Can I burn wood in a smoke control zone?
Yes but you will need to make sure your stove has been defra exempt for burning in a smoke control area. Fortunately there is a growing supply of these from various manufacturers.
Can I connect my woodburner stove to a central heating system?
Many stoves have the option of a back boiler, this can provide hot water or link into a central heating circuit to distribute the heat around the house. You must take care as there are safety implications. You can imagine the damage that an exploding back boiler could do. However a good plumber or heating engineer will install a safe and very effective system that will give you years of cheaper heat.
How much wood will I need?
From our experience one stove heating a room for a year will consume roughly 15 cubic meters of wood. Most merchants sell by the load, and of course that can vary.
Where do I find a reliable wood merchant?
How do I know the wood is dry for burning?
One of the most critical factors in wood burning is the moisture content of the wood. This is where wood seasoning comes into play. Freshly cut wood will contain a moisture content of around 65-90%. This wood should never be used. Apart from producing very low outputs this wet wood will also generate large amounts of soot and tar, which can potentially lead to chimney fires (as these particles will coat your chimney and are combustible). For best results wood should have a moisture content of less than 20%. The process of removing the excess moisture is called seasoning. Seasoning is air drying the wood and can take up to two years. Wood should be stored in a well ventilated, (but covered), structure outdoors. You can buy kiln dried wood but this is not as environmentally friendly as air dried wood.
You can test wood by using a digital moisture meter. You can buy digital moisture meters for around £20
Can you supply a woodburner that I find online?
We are pretty sure we can, just ask!
Tips on using your woodburning stove.
Always burn dry wood, never fresh or wet wood. Wet wood will create slow combustion exacerbating tar and soot build up and creating noxious fumes.
Every time you use your stove burn it hot with ample air to heat up the chimney and crystallise the tars.
Build a well ventilated wood store. Buy your wood at the beginning of the summer and store it for the winter. Wood that has been drying for 2 years is ideal. Make sure you buy seasoned wood from a reliable source.
We recommend you have you stove inspected / serviced and your chimney swept at least once a year.
