If you’ve already decided you want to install a solid fuel stove in your house then you’ve probably done some research online or even gone into your local hardware store or stove supplier. Hopefully this article will give you the reassurance you need to go ahead and make that investment. If you haven’t done any research yet then this article may provide you with knowledge you need to ensure you choose the right stove for your home and your budget.
Quite simply, if you’re going to heat a room or rooms with solid fuel, a stove is an extremely efficient way of maximising the heat output for the financial input. In other words, instead of putting timber, peat or coal into an open fire and have 60%-70% of the heat go up the chimney if you burn that fuel in a stove, you’ll save more fuel and burn less money!
With a solid fuel stove, you have more control over the oxygen getting to your fuel and hence you can make your fuel last longer. Also, you can control your flue and keep more of the heat in your stove and boiler rather than just letting it all go up the chimney – remember hot air rises!!!
If you would like to use your stove to heat your domestic water and radiators in other rooms then you can get a boiler stove and thereby distribute the heat throughout your house by utilising your existing central heating system.
Put simply, if you install a solid fuel stove you could reduce your fuel bill and make your house warmer at the same time. It’s a no-brainer!
There are lots of different types of stoves out there and tonnes of different brands. To simplify things, I’ll break it down into two main categories – dry stoves (or non-boiler stoves) and boiler stoves (HPB stoves).
Stoves can be made from all cast iron, or all steel or a mixture of both. The characteristics of the metals dictate how each stove performs and lasts. To summarise, cast iron takes longer to heat up but holds the heat longer whilst steel heats up quicker but also loses it’s heat quicker. Some stove manufacturers such as Blacksmith Stoves use cast iron in their grates containing relatively large quantities of chromium which gives greater longevity. Remember, stoves parts can burn out and need to be replaced. This can be a hidden cost and manufacturer’s warranties vary so watch out when deciding which stove to buy.
Stoves come in lots of different of shapes, sizes and finishes. A free-standing stove as the name suggests is on a set of four legs and usually either sits on a hearth or plinth and usually heats the room by conventionally heating the air around it which circulates the room naturally or with the aid of a stove fan. An insert stove is a less intrusive device and appears more subtly in the fireplace by having most of its surface area nestled back into the fireplace with only it’s face and a small portion of its bulk protruding into the room. There are other types of stoves such as double-sided which are fitted into a chimney stack shared by two rooms whereby each room can be heated and the fire also accessed via a door on each side. This type of stove, as well as insert stoves, can be installed at different heights depending on the model chosen.
The finishes of each type of stove are typically enamel or matt. Enamel finish is easier to clean and usually comes in different colours although black is still the preferred colour with our customers! Matt is a more traditional finish and some customers love it although it can be more difficult to clean but when polished up with a grate polish can look fantastic. Some insert stoves, and double-sided stoves come in stainless steel or brushed nickel finishes which can provide a very contemporary look.
I often get asked “I want to put in a stove but I don’t know whether I should get one with a boiler or not, what do you think?”. This can be answered in a number of ways and there is no one size fits all approach but I can guide you in a few ways.
If you use a lot of hot water and if you use oil-fired central heating in your home it is well worth considering an HPB stove. However, you will need to consider following things:
If all of the above seem like too much of an upheaval and you’re happy just to have your oil boiler heat your radiators then go ahead and look at installing a non-boiler stove.
With non-boiler as well as HPB stoves you need to ensure you choose the correct size of stove. Obviously, the physical size has to be considered i.e. will it fit on my hearth or do I need to install a hearth or some other kind of plinth such as a tiled platform. Also, how big is the space into which the stove will be installed. A huge 30kw stove is going to look huge in a 3-metre square room – not to mention how uncomfortable all that heat will be! Which brings me to the next question – how do I size my stove?
How do I size my stove?
I’d like to be able to give a scientifically accurate answer to this but you would need to have a doctorate in thermodynamics to give a comprehensive answer. What I can tell you, and this is based on practical experience is the following:
For a dry stove in a house built prior to 2012, with an average sized room to heat – say 3.6m x 4.0m x2.4m you should go for a minimum of a 5-6kw stove and for much older houses a stove up to 8kw should be considered. The larger the space the more power you need. You could go up to a 21kw non boiler stove which would heat the equivalent of a kitchen/dining/living area in an large house. As I said earlier it’s hard to give definitive advice on this and I suggest you speak to a qualified plumber who can calculate the BTU requirements for the proposed space requiring heating. The position of the stove is very important and if you plan on heating a large area then the stove should be centrally located to give the optimal results in the distribution of heat.
The advertised heat output of HPB stoves are split between heat to room and heat to boiler. A typical Henley Druid 21kw stove – one of our most popular stoves - will give 5kw of heat to the room and 16kw of heat to the boiler. The output of most multi-fuel stoves is rated based on burning coal (or smokeless coal) so if you plan to just burn peat or timber, the performance of such as stove will be less. Having said that a stove like this with the correct fuel will provide a comfortable heat to an average sized room whilst the power of the boiler will easily heat the domestic hot water and also heat 8-10 radiators depending on their size.
You may find this an incomplete answer but as I said earlier in the article each house is different and indeed more recently built houses will have greater heat conservation built into their design and will need smaller heat capacity stoves to comfortably provide heat.
How much work is involved?
For HPB, NB, free-standing and insert stoves they each need to have their flues set up correctly. Also, the hearth, fireplace etc. need to be considered and a good tradesman can easily sort these things out. With a little imagination and help from your local or online builders’ merchants you could be the envy of your neighbours with a tastily designed stove installation.
Before you install a stove though, I strongly advise you get a flue professional to inspect your chimney to ensure it’s suitable and safe.
A correctly installed flue will contribute to the overall efficiency of the stove. Each stove has a recommended flue size and therefore if you maintain that flue size the whole way to the chimney pot you will achieve the greatest efficiency. If you have a large flue in your house you can reduce the size by installing a flexible flue liner in the chimney thereby increasing the efficiency of the stove. There are other types of flue pipes you can use also. A word of warning though – you should never install a flue smaller than the one recommended by the stove manufacturer as this could lead to dangerous fumes including Carbon Monoxide escaping from the stove or could increase the risk of chimney fires as well as other hazards.
We stock a full range of flue fittings and can give expert advice on what is the best flue system for you.
As I outlined earlier there is a lot more work involved in the installation of an HPB stove and accordingly the cost involved is greater. However, the upside of heating more rooms as well as your hot-water is a tempting prospect.
Finally, I hope this has given you some idea as to what’s involved in the installation of a stove and with a bit of luck you will purchase the right stove for your home and achieve many years of comfort and save a lot of money at the same time!
