All of our products have CE approval and meet the compulsory EN 13240 regulations.
As well as this all our woodburners have DIN Plus certification which is further testing and improvement to raise efficiency and lower emissions to well below the European regulations.
The DIN-Plus certification program that has been established also contains limit values for hydrocarbons and nitrogen as well as dust particles , this requires higher efficiency than the examination standard levels.
We are proud that our woodburning stoves meet the requirements of the DIN-Plus certification program with our newly developed fire chambers.These levels are met using our Fire-plus system which you can read more about in our Clean Burning System section
Technical Information:
Most good woodburning stoves are very simple to use and your installer should show you how to operate during or after installation. All our wood burning stoves have 2 air controls, the Primary and the Secondary (Air wash).
When burning wood the primary and secondary vents should be open when lighting the kindling .Once a good fire is burning and you have introduced larger seasoned logs then the primary air vent can be closed.
Every stove burns different dependant on the wood you use and chimney/flue system that you have so after a few burns you will get to know your stove and know when to close the primary off.
The fire is then controlled by the secondary/ air wash control above the door. Wood burns from above so only air that is introduced from above the fire will give the maximum benefits for the stove.By gradually closing the top air vent this will enable you to slow the burning down so reduce the speed in which your fuel burns whilst still giving off the heat you require.The more you close the secondary vent the less air the stove will draw in so reducing the capacity to burn fiercly . This in turn means you do not have to re fuel as often as when the air wash is fully open.Never close the air wash fully as this will increase the chance of the glass discolouring and also effect the burning efficiency of the stove.
Always use good seasoned wood for your stove , this can be purchased from many suppliers either by searching on-line or through local suppliers.
But always check before you buy as many suppliers promote seasoned logs but can still have as much as 40% moisture content.
Un seasoned wood can not only
contaminate your stove and flue system but will not give you maximum working efficiency for your stove.If you are going to spend alot of money on a great
stove and installation then it is a good idea to spend a bit of time sourcing the right fuel to maximise your investment.
Hetas recommend around 20% moisture content on logs so the purchase of a simple moisture meter for around £15 is highly recommended so that you can check a few logs before the delivery driver drops a load of " wet, not very seasoned " logs outside your door.
But if you do unfortunately buy any then you can save them until next year!
The burning of any waste may pollute the environment and damage the wood stove, the connecting pipe and the chimney.
Try
not to place more fuel in the fire chamber than the amount given in
the user manual.
The
heating capacity of 1 kg good seasoned wood is between 4 -4.5 kW/h
dependant on type of wood. For example approximately 2 kg of seasoned beech wood can be
burned in a nominal 8 kW output wood stove every hour.
While
heating up the woodburning stove the lining of the fire chamber may become discoloured
but this will dissapear as soon as the fire chamber reaches the operating
temperature.
When opening the door to place more logs in always open slowly as the sudden introduction of fresh air can make the flames jump out
If you need less heat from your stove then load less fuel, and reduce the air intake.
Remember wood burns from above so the adjustable secondary air will control
your burning range .
Always have your stove fitted by a Hetas Certified installer as this is the only guarantee that it has been fitted to Building Regulations Document J .
You will automatically be given a Hetas certificate of which a copy will be sent to Your local authority making your household insurance valid if any problems
occur with your stove.
If you are to carry out installation yourself or use a builder who is not Hetas certified then you will have to contact your local authority to see if they have
any engineers capable of certifying the installation. This is not always possible and if it is they normally carry a fee of around £150 to certify.
