How to stop smoke from seeping into the room when lighting my cold Heta Stove?
If smoke seeps into the room when lighting your Heta Stove while it's cold, but it burns well once heated, this indicates an inadequate chimney draft. To resolve this, improve the chimney.
Why does my Heta Stove burn poorly after warming up and the glass gets sooty?
If your Heta Stove burns poorly after warming up and the glass slowly soots up, this could be caused by soot in the flue pipe. To resolve this, clean the flue pipe regularly, limit the use of horizontal flue pipes, and avoid using firewood that generates large quantities of ash.
What to do if my Heta Stove has too rapid combustion?
If your Heta Stove is experiencing too rapid combustion, it could be due to too much chimney draft. In this case, measure the chimney draft and install a damper in the flue pipe if necessary. Another potential cause is a defective door or ash pan/drawer seal, which would require replacing the seal.
What to do if Heta Ambition 5 burns poorly after start-up and the glass slowly soots up?
If your Heta stove burns poorly after start-up and the glass slowly soots up, several factors could be responsible. It could be due to inadequate chimney draft, so you should improve the chimney draft. Ensure sufficient air supply by reading the operating instructions. Damp wood is another potential cause; firewood should ideally be dried for at least one year after splitting. Firewood pieces may be too large, so use smaller pieces. Finally, insufficient air supply to the room from range hoods or airtight windows could be the issue. Depending on the cause, windows must be opened, or the outdoor air connection cleaned.
Why condensation appears from Heta stove flue pipe?
Condensation from the flue pipe of your Heta stove can occur if the pipe is too long or the chimney is too cold, so improve the flue pipe and insulate the chimney. Another cause can be damp wood, so ensure you are using dry firewood.
Why Heta stove creaks?
If your Heta stove creaks, it is because the temperature in the combustion chamber is too high. See the operating instructions.
Why condensation appears in Heta stove combustion chamber?
Condensation in the combustion chamber of your Heta stove can be caused by moisture in the vermiculite, which evaporates by itself after the stove has been lit a few times. It can also be caused by damp wood, so ensure you use dry firewood.
