How do I search for a spare part?

Some or all of the following pieces of information will help you find the correct spare part for your stove;

1. The make or brand of stove, e.g. is it a Firewarm, Vitae, TR, Green, Firefox, etc?

2. What model is the stove? This can be found on your stove manual or on the data plate (located inside the stove).
 
3. Stove kw? What size is the stove, e.g. 6kw, 9kw, 20kw, etc?

4. What part needs to be replaced, e.g. glass, coal catcher, ashpan, etc? you can view individual spare part images under Stove Parts Terminology.

 

What type of stove do I have?

Insert Stoves:

The Heat Design Insert Stove is the simplest type of stove, and it can be inserted into an existing solid fuel fireplace with a 16/18 inch flat opening. Although this stove is simple to install, we recommend that it be installed by a qualified stove installer or fitter, and they should check the chimney to ensure that it is suitable, i.e. In good condition, dry and free from cracks or defects, with a flue diameter not less than 150mm and not greater than 200mm – if this is not the case, the customer may still be able to have an insert stove, but the flue will need to be lined.

• An insert stove, even when not lit, will increase the energy rating of a house, as it prevents room heat from escaping up the chimney.

• An open fire can be as low as 20% efficient, whereas a Heat Design Insert Stove offers between 75% and 81% efficiency depending on the model chosen.

• The large window and Airwash technology in a Heat Design Insert Stove gives a clear view of the flames, providing the beauty and comfort of a real fire, with the twin benefits of lower fuel costs, and a lower carbon footprint.

• The Heat Design Insert Stove is a 4Kw device, and thus does not need additional ventilation sources. It is important to note that no stove should be installed in a room with an extractor fan. We will look at how to calculate the size of stove needed for the room later on.

Cassette Stoves:

A Cassette Stove, unlike a “normal” stove is not free-standing, and is designed to be seated into a suitably flued and insulated opening. A Cassette Stove can be fitted into an existing fireplace by a suitably qualified fitter or heating engineer. It can also be fitted into an existing chimney, and made to look as if it is wall hung, to provide a stunning contemporary effect.  All Cassette stoves must be flued, and an adaptor fitted so that it can inserted into the collar of the stove on fitting.

• An open fire can be as low as 20% efficient, whereas a Heat Design Cassette Stove offers between 78% and 80% efficiency depending on the model chosen.

• The large window and Airwash technology in a Heat Design Cassette Stove provides a clear view of the flames, providing the beauty and comfort of a real fire in a contemporary setting, with the twin benefits of lower fuel costs, and a lower carbon footprint.

• Heat Design Cassette Stoves are available in a 6kW, 9kW & 11kW option, and will need an additional ventilation source.

Free-Standing Stoves:

There is a wide range of Heat Design Free-Standing Stoves, from a Non-Boiler Stove available in heat output options of 4kW, 6 kW, or 8 kW, 12 kW & 16 kW and an 8 kW, 12kW, 16 kW, 18kW, 25 kW & 30kW boiler Boiler Stove, capable of heating up to 18  radiators, and providing hot water.

Boiler Stoves:

Our Heat Design boiler stoves can be used to provide a central heating system, including heating radiators and providing hot water, or they can be linked to an existing central heating system to create a multi-source heating system.

Stove Operation and Ventilation

Stove Operation

It is best practice to have two or three small fires before operating a stove to its maximum heat output. This is to allow the paint to cure and castings to relax and consolidate location we recommend ‘running in' procedure after long shutdowns to preserve life of stove. During this process the stove may produce an unpleasant smell. (something similar to an electric storage heater produces on the first few uses after being off for a prolonged period). It is not toxic, but we would suggest that for customer comfort during this period doors and windows are left open.

  • First, load the fire with starting fuel i.e. paper, dry kindling timber and/or fire lighters in the mode chosen, either wood or coal. 
  • Light the fire at base leaving all air controls open. Allow the fuel to reach a steady glow and build the fire up gradually. Once you have a good fire established across the grate bed, further fuel can be added as required.
  • When your fuel is well alight you can start to restrict the primary air intake. If you are burning only wood, the primary air control can be fully closed. If you are burning solid fuel you will require more primary air. Your stove is burning with maximum efficiency when a bright fire is achieved using minimum air inlet.
  • The stove can be banked up for long periods. When burning solid fuel empty the ash­ pan. Open air controls and let the fire burn brightly for a short period. Refuel and close air controls, the exact setting required will depend on the fuel used and the chimney draw so some practice may be necessary. To revive the fire, open air controls until the fire is burning brightly, de-ash if necessary (solid fuel only) and refuel. Set air controls as required.
  • Running temperatures – A stove should be run hot which will enable a cleaner performance, but do not overheat the appliance. The ideal burning temperature is between 250°C and 450°C, this rate can be measured using a Heat Design stove pipe thermometer. Ideally the air controls should be set to create a lazy bright flame.

Stove Ventilation

Stoves need a supply of air for combustion, and to evacuate the flue gases otherwise they will not work. Without an air supply the stove will not light and smoke is likely to pour out into the house. The smoke will not be able to be drawn up the chimney as this requires air movement up through the chimney which is not possible if there is no source of air. Sometimes sufficient air can come through the building itself and no dedicated ventilation is necessary.


If additional ventilation is required, the vent should be placed in such a way that it cannot be easily blocked and so that house residents are not tempted to block it off to reduce draughts or noise.

It can be a good idea to place the vent close to the stove. Because the stove draws the air that it needs for combustion through the vent there will be a draught from the vent to the stove. If the vent is close to the stove then draughts are reduced and the house stays warmer.
If there is a mesh to guard against pest/mice etc coming through the vent then the mesh size must be no less than 5mm.

Stove Maintenance

For the best performance, your stove should be serviced at least once a year at the end or beginning of the heating season. Servicing your stove at end of the heating season will allow you plenty of time before the new heating season starts should you need to source spare parts.

Stove Maintenance Checklist
√ Do a smoke test on your stove. Light a smoke pellet and close the stove door. Smoke should go up chimney. If the smoke lingers in the firebox there may be a blockage in the flue pipe

√ Check your chimney each year before starting to use your stove for the winter. Birds may have nested in the chimney or the masonry may have cracked. Both chimney and flue pipe must be swept at least once a year.

√ The baffle plate should be removed at least once a month to prevent any build-up of soot or fly ash which could lead to blocked flueways and dangerous fume emission. If the baffle plate is removed the chimney/flueway can be swept through the appliance. This plate locates the back and side firebricks so note its position before removal. To remove, lift plate and remove one side brick, this will allow plate to drop and aid removal. To replace, position baffle plate on back and side brick, lift plate and replace remaining brick, make sure it has located in position. This must be done when the stove is cold. For efficient burning of your appliance, make sure the grate is clear of burnt debris i.e. nails etc.

√ The stove is finished with a heat-resistant paint and this can be cleaned with a soft brush. Do not clean whilst the stove is hot, wait until it has cooled down. The finish can be renovated with a suitable brand of paint.

√ Clean the glass panels when cool with a proprietary glass cleaner. Highly abrasive substances should be avoided as these can scratch the glass and make subsequent cleaning more difficult. Wet logs on heated glass, a badly aimed poker or heavy slamming of the doors could crack the glass panels. The glass will not fracture from heat.

√ Check that the riddle grate is working correctly

√ Check the fire grate or grate bars / plates

√ Check the baffle plate

√ Check the ashpan

√ Check the door rope seals. Ensure that they are not coming away from the door

√ Check the carbon monoxide alarm using the test button
