What Sizes Do Wood-Burning Stoves Come In?


What Sizes Do Wood-Burning Stoves Come In?

The size of a wood-burning stove is usually given by its heat output in kilowatts (kW). The figure you’ll see displayed prominently in relation to a stove is the maximum heat output of which it’s capable. These figures are dependent on operating the stove at full capacity and efficiency. They are neither 100% accurate, nor uniform between different manufacturers, but they do provide a helpful guide when comparing different stoves.

 

Most wood-burning stoves manufacturers tend to start their range with a 4kW to 5kW entry model. These small stoves are mainly intended for use in cabins, boats and compact rooms.

The next group of stoves tend to be between 6kW and 10kW in size and are usually suitable for average sized rooms.

 

Mazona Orlando 10kw Stove

Mazona 10KW Stove

 

Anything above 10kW and you’re looking at a sizeable wood-burning stove capable of heating a fairly large space.


What factors should affect the size of wood-burning stove you buy?

The ultimate defining factor when deciding what size of wood-burning stove to buy is the size of space that you need to heat. The size of heat output you choose should correspond to the size of room in which the stove will be installed.

Tools like our heat output calculator can help to guide you towards the approximate size of stove that should be suitable for your home. Obviously, the larger the space you need to heat the larger the stove you’ll need to do the job.


Other factors to take into consideration include:

  • How well insulated is your home?

If you know your home has poor insulation or is prone to draughts, you might err on the side of caution and buy a slightly larger stove than is recommended for your room size.

  • What is your budget?

A nice looking stove is pointless if it isn’t also big enough to heat your room. If your budget isn’t going to stretch to the size and design you want, it’s better to scrimp on the design and ensure that the stove serves its primary purpose of keeping you warm.

  • Do you want to create more heat than you really need?

Some people prefer to buy a bigger stove than they need and run it at less than full capacity most of the time. That gives the option of having a larger fire if you’d like to spread the heat into adjacent rooms. Operating stoves in this way does not give you the best efficiency levels, but it does provide a bit more flexibility. However, it also creates the risk of overheating your room, particularly if you’re new to wood-burning stoves.

  • Is it a boiler stove?

If you’re buying a boiler stove, which will also heat your water and radiators, you’ll need to factor in that a considerable amount of the heat output will be used on heating the boiler. It’s important to buy a larger stove than you would need to heat the room alone to counter this.

  • What other forms of heating will you be using?

The workload of your stove will vary considerably depending on whether you’re planning on using it in conjunction with another form of heating or if it will be the main source of warmth in your home.

@ Rob BC Hi Rob Thanks for your comment. Unfortunately, you're in the minority on this. We know
from the thousands of enquiries we receive that most people are referring to the size of the heat
output when they refer to stove size. That's why we have a stove size calculator to work out heat
output: https://www.gr8fires.co.uk/?utm_source=Social


Rob BC 2017-11-30 15:08:34
Any answer that ends in kW is not a "size", its a heat output. A question like "What sizes do
wood-burning stoves come in?" should be answered in 3 dimensions, height, width, depth. That's why
people ask for the size, because they want to know how big the actual thing is.

@ Ian Galtrey Hi Ian Based on those dimensions, you'd be looking at something in the 6kW to 9kW
bracket: https://www.gr8fires.co.uk/stoves/all-stoves/stove-heat-output/6-kw-to-9-kw Our most
popular stove, the Mazona Rocky, falls into this category:

my fire opening is27" wide 42"high the chimney as been rebuilt with a 8" pot flue .the room is
25foot by16foot what size stove would you recommend.


Gr8Fires 2016-03-18 12:31:06
@ Daniel Bennie Hi Daniel It's definitely working - we just used it with your figures. You're
looking at around 4kW. Thanks, Gr8Fires


Daniel Bennie 2016-03-18 12:10:58
The stove size calculator does not seem to be working my room sizes are L 4600mm W3600m H 2600, what
KW would I need.

@ Darren Missenden Hi Darren, it's not an exact science, so it is tricky to say. We'd recommend
trying to calculate as if the space was one room and seeing what that comes out at. Obviously the
heat will rise, so we'd suggest edging towards too big rather than too small. Thanks.

@ Jim Edwards Hi Jim, Some offer both options, some only have one or the other. Rear exit flue is
what you're looking for. This will normally be detailed on the product page. Thanks.

@ richardkent Hi Richard, The liner size will depend on which model you choose. You'll be able to
find a list of approved installers in your area on the HETAS website:
http://www.hetas.co.uk/find-installer/. Thanks.


Darren missenden 2014-12-29 12:15:55
I have an open plan stairs in my dining room. Using the calculator it only works out I need a 3 kW
to heat my room so how do I calculate a room with stairs in it. I can't close them as it's a listed
16 century house and can not be altered. If I use a six kW will this be sufficient to cater for my
stairs?, regards Darren.


Rus Skelton 2014-11-29 17:43:26
hi I was wondering how much space I need to leave around the log burner to get the best results from
it? The opening I have to put it in is 57cm wide 60cm deep and 75 cm high at it's highest point.
Thanks Rus.


jim edwards 2014-11-27 13:26:58
can the cast iron stoves have the flue out the back i see you show of the stoves with the flue out
top thanks


richardkent 2014-10-19 03:08:57
I have a small room so 4kw is ample,what size liner is required,what ather parts do I need and do
you have a list of installers in the Cumbria area.I feel confident to do the job but I have ms so it
gets harder to do .

Thank for the kind words, Vernon. We look forward to hearing from you again
soon. Thanks, Gr8Fires.co.uk


Vernon Ault 2014-01-05 13:17:46
Thank you very much for the excellent web site. You offered me all the information that I could
require and I shall be in contact with you shortly with reference to purchasing a stove from you,
Yours sincerely, Vernon Ault

Hi Jonathan, Are you talking in terms of a boiler stove to heat radiators and water? If so, a boiler
stove can be plumbed into your existing system so that you can heat from either your existing gas
boiler or the boiler stove. Just let us know if that's not what you meant. Thanks, Gr8Fires


Jonathan butler 2013-11-26 21:07:52
Considering a stove that we can use in conjunction with our gas central heating. Can this be done so
that we can use thie gas sometimes and then use the stove other times. Thank you


Gr8Fires.co.uk 2013-11-21 13:13:55
Thanks for the feedback, JT. It does become a bit trickier once you factor in the various quirks of
different properties, though. That's why we keep it quite simple. Thanks, Gr8Fires


Gr8Fires.co.uk 2013-11-21 12:37:29
Hi Roger That should be fine. The calculator is just intended as a rough guide and doesn't factor in
how draughty a room is or other factors, so a 4kW should be spot on. Thanks, Gr8Fires


roger pratt 2013-11-12 16:47:34
On your calculator it has given me the reading of 3.1 KW Would a 4KW be okay Regards Roger
