To calculate the kW you require to heat a room to around 22ºC when the temperatures are at freezing point outside you simply multiply the height width and length of the room, you then divide this by 14. So, a room measuring 6m long by 5m wide and with a height of 2.5m is 75m3. Divide this by 14 and you will require a 5.36kw stove, OR 5kw in round numbers.
Hot Box Stoves strongly believe that it is important for our customers to choose the correct fire to adequately heat the space required and that the appliance is installed correctly.
Our small priced survey ensure that you discuss matters personal to you with our on-site surveyor (not a salesman) who has the complete skill set and knowledge to specify what is and isn’t achievable for every installation. After which you will be submitted with a written quotation outlining details of your planned installation.
Our fitting teams consist of two qualified installers employed by Hot Box Stoves. We do not use Sub-contractors and the majority of installations can be completed in one-three days.
Many issues regarding lighting a wood burning stove and achieving the required heat output can be down to the wood being burnt. We recommend to all customers that they strictly burn only dried hardwood logs. Kiln dried wood is also readily available and dried to an average moisture content of 20% and suitable for immediate burning on your wood burning stove.
Twin wall flue pipe is a “clip-together” chimney system that can be used to safely take the combustion gases from a wood burning stove and to the atmosphere. Twin wall flue is a metal tube (flue) insulated with approx. an inch of insulation (two layers of stainless steel with insulation between).
If your chosen stove is more than 5kW then it is likely. Our surveyor will direct you further.
We have always tried to work to quite specific minimum dimensions for any recess that we create to ensure both adequate clearances and escape of heat into the room. Where practicable we would size the recess to the stove but often 1100mm high by 900mm wide offers the ideal aperture.
There are many factors that can determine the cost of an installation such as access constraints, do we need a scaffold or cherry picker? Our advice is to contact us to get a quotation, we are really quite helpful! If you want a quick quotation without a site survey, then send us over some images of the outside of your house from a distance with the chimney visible and the existing fireplace and we will send you over a basic installation quotation. Please direct this to email@example.com
At Hot Box we always specialise in wood burning stoves. The main difference is that wood burns best on a bed of its own ash without a grate, where smokeless fuels need a grate to remove the ash or combustion bi-products.
Smokeless fuels are becoming increasingly less popular as wood burning stoves become cleaner and approved for smoke controlled zones through DEFRA. Our argument has always been around what would you prefer to see in your living room? Nice clean dry logs which can be handled into your stove or black lumps of smokeless fuels that you need a shovel to shove into the fire?
Smokeless fuels will burn for longer with no flame and provide good heat over time but are not very good for flues and liners. Decent quality dry hardwood will provide ample heat, look pretty and not mess up your carpets?
After the cold winter months or on an annual basis, as well as having the chimney swept, your stove should also have a service. This includes stripping, inspecting and cleaning of the appliance. This is best carried out by a HETAS Registered Engineer.
DEFRA (Department of Environment, Farming and Rural Affairs) state that certain areas in the UK usually cities and built up areas are not allowed to burn wood as a fuel due to the smoke and pollution created. However, if you install a DEFRA Approved Stove that has been tested by DEFRA you are able to burn these exempt fuels (i.e wood). 90% of our stoves are DEFRA approved.
There is information stating it is ok to install a wood burning or smoke exempt stove without a flexible liner. If a chimney can be declared sound by carrying out a smoke test and providing it is the correct dimensions specified for the stove as stated by the manufacturer, then you do not have to fit a chimney liner.
For this reason and to guarantee manufacturer’s warranty we install a flue liner with all stove installations and because UK Chimneys were not designed for stoves but for coal fires. The large square flues are too wide to ensure smoke will travel up without a flexible liner. When the stove is first lit the chimney will be cold and could have draft issues making it difficult for the chimney to draw the smoke that the stove initially makes. The smoke will travel into the room (called smoke spillage) and can lead to Carbon Monoxide poisoning.
