What size stove do I need for my room?
We generally calculate this by using Kilowatts (kW, a thousand Watts) per hour, commonly just referred to as kW.
When choosing a stove we need to ensure that it is the right size as if its too large it will have to spend much of its time turned down, this leads to too much smoke, tar and consequently poor performance. If the stove is too small it will be constantly running at a high rate which will result in very frequent refuelling and over firing.
For a general idea of the size required enter the dimensions of your room into our calculator to see what size stove we recommend for your room. PLEASE NOTE: This is to be used as a guide only. We strongly recommend a site visit by us in order to give you a more accurate recommendation.
It is very important to allow your solid fuel appliance breath properly or the flue will be unable to take away the fumes effectively. Inadequate ventilation can lead to smoking back or slow gas speed inside the fire and chimney. The chimney can soot up much faster. Insufficient air flow will also lead to incomplete combustion, resulting in potential increased levels of carbon monoxide.
In the case of an open fire with or without boiler, air opening/s with a total free area of at least 50 percent of the throat opening area should be provided. This is usually 16,500mm2 for a typical open fire. This is ventilation to the room from outside the building.
Houses built before 2008 normally have a 5KW heat output allowance without the need for a vent. If the stove is bigger than 5KW a vent must be fitted. The vent needs to be 550mm2 per KW over the 5KW. This means an 8KW stove would need a vent of 1,650mm2.
If the house was built after 2008 then a vent needs to be fitted that is 550mm2 per KW. So an 8KW stove in a new build would need a vent about 4,400mm2 or as advised by the appliance manufacturer – whichever is the greater.
NOTE: It is sometimes necessary to fit a vent in an older property with a 5KW stove if there is not sufficient air to the room, or, if the property had undergone significant draught proofing or heat loss prevention measures such as double glazing, cavity wall insulation etc.
We will be able to advise you on your ventilation requirements.
