Fireplace Price

calculate your budget

When purchasing a slow combustion fireplaces first determine what you would want to spend. Remember that all prices on closed combustion fireplaces are quoted excluding the flue kits, cowling and installation; this can still add a further R7000, 00 on top of your wood burning, slow combustion fireplace price.

Our online quote request will indicate the flue kit cost based on the finish selected and and the installation site. The installation labour price and extras like floor plates and roof seals are not included.


determine your kilowatt output requirements

Take the volumetric size of the room you wish to heat into consideration to determine the kilowatt output of the slow combustion fireplace you need to buy. In layman’s terms you would require 1kw for every 10m² if your ceiling height is 2.7m. We normally recommend that you choose a fireplace that is 2kw over the required room size to compensate for heat loss through poor insulation. Remember that if you have an open plan living area you should also allow for the adjacent rooms in your calculation.

Choosing a type of fuel to burn

You need to determine if you wish to burn anthracite in combination with wood before purchasing your slow combustion fireplace.

Most of the slow combustion fireplaces available in South Africa are wood burners only. The kilowatt rating supplied on the fireplaces is all determined based on burning wood; the heating capacity of wood is greater than that of anthracite and it gives a much nicer flame effect.

The dedicated anthracite burning fireplaces are normally top loaders, these units give off less heat than the wood burners but they can be burnt continuously for long periods on end. 


Slow combustion collections

The big deciding factor in existing houses between freestanding and build-in is normally price. The freestanding units work out cheaper to install than the build-in units. In newly build houses clients tend to go for the build-in option rather than freestanding due to cost of building being incorporated into the overall building cost of the house. The advantage of the build-in option is that you can change the look of the fireplace by adding a mantle-piece or painting the fireplace structure whereas with the freestanding your look will remain the same.  

When choosing your freestanding fireplace you will be faced with two options [1] Radiant units – body of the fireplace releases the heat [2] Convection units – hot air is moved through a double layer of steel. The benefit with a convection fireplace is that you would be able to position the fireplace much closer to combustible materials such as furniture.

yearly maintenance



Servicing and cleaning forms an integral part of maintaining your fireplace. A small layer of ash should always remain on the floor plate, this will protect the floor plate and create a high base temperature below the fire. The ash draw should be cleaned out after every use to prevent the ash from heaping up and touching the under side of the grate and distorting it.

Wet wood which is not seasoned properly will cause soot collection on the fireplace window, this can be cleaning off by using a damp cloth and some of the ash as rubbing compound, then clean with a clean damp cloth.

Before the start of the season check that the door and glass rope seal is intact to ensure that your fireplace efficiency stays optimal. Have the chimney swept regularly to prevent chimney fires, this can be done every two to three years depending on how often you use your fireplace. Check that your fireplace liners are intact, these liners prevents the fire coming into contact with the steel body. 

The inside of your firebox will oxidise where the flames burns off the high heat paint and the oxygen binds with the exposed steel. To slow this process down a light sand will be required and respray with an appropriate high heat spray.Remove the top baffle plate and clean out any soot that might have accumulated there.

It is advisable to always leave some ash on the floor of the fireplace, this will protect the floor plate and will help to build and maintain a fire. Special care should be taken to clean the ash pan below the fire grate in order to prevent the ash from touching the grate. Not only will this prevent air flow it will cause the grate to burnout prematurely or warp due to the exposure of excessive heat. The primary air on the fireplace should be used for start up in the fully open position only, there after it should remain only 20-30% open otherwise to much airflow through the grate can cause a similar effect to the above mentioned where the floor plate can be warped.

Slow Combustion Fireplace Maintenance

  • Rotating cowls must be greased twice a year. Not greasing the cowls will relate in water leakage and the fireplace smoking.
  • All steel exposed above roof level will corrode and should be treated accordingly. paint with NS4 and topcoat with enamel paint. s/steel parts will discolour when heat is applied.
  • When build-in braais or fireplaces are installed an expansion gap pf 20mm should be left between the brickwork and the unit.
  • All juntions and cowl boxes must be fixed with rivets or self-tapping screws
  • All seams on flues, junctions and cowl boxes must be sealed with heat resistant silicone.
  • Silicone wire should be used to connect the light fitting.
  • Any water leaks that may occur should be reported to the relevant installer directly by yourself, their contact numbers can be obtained from us.
  • Hyper Fires does not take the responsibility of any water leaks down the inside of the flue due to the cowl being galvanised [galvinsed cowls are heavy and to slow].
  • Please note that the installers used to install your fireplaceare subcontracted to you and should be paid directly by yourself.
  • All freestanding fireplaces are supplied standard with 3,6m flue. Any adional flue required to ensure the fireplace working optionallyare for the clients own account [unfortunately it is not always possible to advise telephonically the length of flue required]
  • Fireplaces and braais can be painted with Etch coat primer
  • Please note that it will seem as if the fireplace is smoking the first time when lit. This is quite normal, it’s the paint burning in. The fireplace will also give off a chemical smell, this will disappear after the first couple of hours.
