Questions about fireplace designs, installations and more?
Heat output vs fuel input is outstanding on a slow combustion heater. Conventional open fireplaces provide 20% heat on 80% fuel and is generally inefficient. Closed system fireplaces (slow combustion) provide 80% heat on 20% fuel and are extremely efficient heat generators. The rate of combustion is totally controlled with adjustable air intakes. This ensures hours of cosy heat with one load of fuel. Although the initial cost of closed system fireplaces is higher than open steel fireplaces, the saving is doubled in the long run with low fuel cost and no need for additional heating in the area i.e. electric heaters, gas roll around heater, etc.
Solid fire-resistant glass doors are fitted to units for maximum view of the fire and are fitted with an air wash cleaning system to ensure a clear view. With our Closed System fireplaces, you can enjoy the magic of an open fire with the efficiency and safety of a closed system fireplace.
Cast iron is resistant to strong thermal stress and retains its shape. Therefore, doors and joints always remain tight with rope gasket seals that prevent soot or smoke leaking into the room. Closed system fireplaces also draw incredibly well and are often the solution to a smoky open fireplace.
- My house already has a chimney, can I connect a new stove to it?
- What is the difference between an open fire and a closed stove?
If you would like to connect a new stove or fire to your existing chimney, we recommend you always seek advice from a recognised service provider. Connecting a new stove or fire to an existing chimney isn’t necessarily impossible, however the question as to whether your chimney is suitable for the stove or fire you wish to connect depends on many factors, such as:
- The quality of the flue
- The diameter of the flue
- The length of the flue
- The material the chimney or the flue is made of
This applies to connecting either a gas fire or wood stove. Our technician will assess your situation at home and will consequently provide you with more accurate information on the options available to you.
Nowadays wood stoves and fires have extremely high outputs and very good combustion rates. The models are well thought out and ensure the wood is burned as efficiently and cleanly as possible. This, unfortunately, cannot be said of the open fire. But why is that? The first big difference lies in the fact that all contemporary wood stoves and fires are closed, simply by equipping them with a glass window/door. You may perhaps think this will be at the expense of heat output. But nothing is further from the truth! Because the stove is closed, the temperature in the combustion chamber rises.
In addition, many models are further insulated with rear vermiculite walls and the flue gases are fed away via an ingenious labyrinth. This maintains a high combustion temperature and all released matter is burnt to the optimum. Resulting not only in far cleaner combustion, but also in full enjoyment of the heat emitted.
To illustrate: An open fire attains just 15% output as much of the heat is lost via the flue. A contemporary wood stove or fire attains an average output of between 60 and 80%. In addition, the emissions from an open fire as opposed to a good wood stove are many times higher. When both are used to heat a room, the open fire appears to have 15x higher CO emissions than the wood stove, and 50 x more particulate emissions than the wood stove.
Chimney sweeping is of utmost importance and must be done at least once per year as to safeguard your health and the safety of your home. It is strongly recommended to schedule this service prior to every winter season so as to avoid disappointment on scheduling dates during the busy winter months. Please read the following why Chimney Sweeping is important.
The primary job of a chimney sweep is to aid in the prevention of chimney fires and reduce the risk of dangerous fume emissions from blocked heating applications, flue ways and chimneys. A chimney needs to be swept because it is an exhaust system for your heating appliance. Having your chimney swept by a professional reduces the build-up of tar and other deposits which form on the internal walls of the flue way (generally caused as a result of incomplete combustion of the fuels used).
Areas of concern must be dealt with as a matter of urgency. Soot from coal, wood, oil and gas fired systems must be eliminated as well as obstructions such as birds’ nests etc., removed and to ensure that the flue has not been partially or completely blocked as a result of debris falling down the chimney (generally caused by birds nesting or tiles, slates or masonry falling down the chimney stack).
An un-swept flue can lead to poor combustion of your solid fuel resulting in at the very least an inefficient method of heating your home. In worst case scenarios it may also lead to chimney fire or Carbon Monoxide poisoning.
Soot is classified as a hazardous product (it contains cancerous carcinogens).
Chimney sweeping is one of the important aspects related with chimney cleaning and chimney inspections. When the chimney is used, residue produced by burning wood accrues inside the chimney. This also creates blockage in the chimney, which should be removed as early as possible after detection. It is good practice to pay special heed over chimney maintenance tasks. By doing regular chimney maintenance tasks you will not only ensure smooth functionality of your chimney, but safety of your household too.
From outside, your chimney might appear alright to you. But you never know what is going on inside. With the passing time dirt, debris and other such materials collect in the chimney. So, before you start using the chimney it is important to have it checked by a professional sweep to ensure that the chimney is in healthy working condition or in need of repair.
Here are key reasons to rely on a chimney sweep service:
To clean the built-up: The chimney sweep will clean the creosote and all the other built up of chimney.
To repair cracks: Even if your chimney is not used for an extended period of time, cracks appear on the wall of chimney which could cause the chimney to collapse. Through correct chimney sweeping, these cracks can be repaired, and the chimney can be prevented from collapsing.
For a proper chimney inspection: The chimney sweep will thoroughly inspect your chimney to ensure that your chimney liners are in proper working condition and to assess whether your chimney is safe for use or requires repair and replacement.
Many closed system fireplaces offer the option of burning wood, anthracite and coal, and others are only wood-burners. Wood is preferred in many cases as it is much cleaner than anthracite. One load of anthracite with the correct damper settings can burn for up to 12 hours but must be cleaned at the same time as it is next loaded. The unit can continuously burn, refuelling and emptying the ash pan every 12 hours.
As it is one of the coldest regions in the world, it is no surprise that most closed system fireplaces are developed and manufactured in Europe. European companies have perfected the art of designing and manufacturing closed system stoves which are known for their outstanding quality, expert design and efficiency regardless of brand or importer.
A closed system fireplace has an airtight seal which ensures a safe, contained and controllable fire. There is no risk of hot fuel emitting from the fireplace which could be a potential fire hazard. Caution should be taken with young children around closed system stoves as their surfaces do reach high temperatures, which can result in burn injuries if touched. However, children quickly become aware of the boundaries set by the heat radiation of these units and soon learn to safely enjoy the cosy heat.
Our installations are conducted by our very own trained team of technicians who have many years of experience in the specialist trade of installing closed system fireplaces. Free standing and built-in units can be installed in various ways according to our clients’ requirements where possible, albeit a completely new installation, conversion or upgrade. Installations are mostly completed within a day and only the best materials and flue systems are applied to ensure that we comply with European standards.
