TermaTech’s stoves are convection stoves. Their basic structure is produced in 3-5 mm thick quality steel. Cast-iron components are always used in TermaTech stoves where the temperature is highest. Examples of this are the bottom of the combustion chamber, the internal frame of the door and other parts.
The most important thing is that the stove is built to last for many years and you are assured of this when you choose a TermaTech wood-burning stove.
STOVE TYPE – EMISSION OF HEAT
Roughly speaking, there are main three types of stove: Radiation stoves, convection stoves and storage heating stoves.
The drawback with radiation stoves is that the surface of the stove gets very hot and the area immediately surrounding it gets hot rapidly. Very few of the stoves produced today are radiation stoves.
Convection stoves, which are the most common type of stove on the market today, have an external jacket, which is open at the top and at the bottom. The air between the actual stove and the outer jacket is heated up and the warm air is sent out of the stove and the air circulated around the room. The air is distributed better than it is with radiation stoves.
Storage heating stoves accumulate the heat from the wood-burning stove in order to emit the heat over a longer period later on.
AIR WASH SYSTEM
Warmed air is blown down the inside of the glass and counteracts and minimises the formation of soot on the glass. All TermaTech stoves are equipped with an air wash system.
Generally speaking, wood-burning stoves do not require much cleaning. However, you must check all sealing bands and moving parts before the start of the heating season and rinse and clean the inside of the stove once the heating season is over. The ash is emptied as required, but be careful – if there are smouldering embers in the ash there is a risk of smoke or fire damage in your waste receptacle etc.
The glass is cleaned either with TermaTech’s special glass cleaner of with a little bit of water on a piece of kitchen roll which is then dipped in the ash and used to scrub the inside of the glass.
The surface of the stove is cleaned using a dry cloth, a soft, dry brush or a tightly scrunched up moist cloth. Never use water or cleaning agents on the painted surfaces.
TOP OR REAR OUTLET
The rear outlet solution requires a good passage of air from the chimney since this solution creates more resistance to the path of the smoke. The smoke should preferably follow its natural trajectory – upwards.
Soapstone is a natural product which has an outstanding ability to retain heat. This stone is often used for storage heating stoves where a more even distribution of heat is desired. Every single soapstone has millions of years of history behind it and has a unique appearance and structure.
Even the very best wood-burning stove cannot function properly if it isn’t connected to a good chimney. The chimney is “motor” or “lungs” of the stove, if you like. A poorly insulated chimney or chimney that is too low will often result in a bad draught.
A bad draught results in poor combustion and smoke spillage when the door is opened.
An insulation material that affects the temperature in the combustion chamber and, consequently, results in a higher temperature and cleaner combustion.
EXTERNAL COMBUSTION AIR DUCTS
A connection whereby the air required in order for the stove to function correctly is supplied externally. An external air supply to the stove’s combustion air duct is often necessary in new houses because the houses are extremely airtight. In airtight houses, a vacuum can easily be created which means that the wood-burning stove is not able to function correctly.
