A closed combustion fireplace burns wood in a sealed firebox behind glass, drawing its air supply in a controlled way instead of sucking warm air out of the room like an open hearth. The result is three to four times more heat from the same wood, a glass-fronted flame view, and no smoke in the room. Getting that performance, though, depends almost entirely on the installation.

What a combustion fireplace installation involves

Every closed combustion installation has the same core elements, and each one affects how the fireplace draws, heats and lasts:

  • The flue system – correctly sized single-skin and insulated flue sections, routed through the ceiling and roof with the right clearances and finished with a cowl. Most draw problems and smoke leaks trace back to a flue that is too short, too narrow or poorly sealed.
  • Floor protection – a hearth or glass baseplate under and in front of the stove, protecting wooden and carpeted floors from heat and embers.
  • Clearances – safe distances from combustible walls, curtains and furniture, per the manufacturer specification for the specific model.
  • Ceiling and roof penetrations – fire-stop plates, flashing and weatherproofing where the flue passes through, done so the roof does not leak and nothing combustible touches the hot flue.

What does it cost?

For most homes, a complete closed combustion installation – fireplace, flue kit and professional installation – lands between R18,000 and R45,000 depending on the stove you choose and how far the flue must run.

Why use a professional installer

A combustion fireplace is a sealed system – the stove, rope seals, flue joints and roof penetration all have to work together. Fire Flame installs closed combustion fireplaces across Cape Town and the Western Cape: we size the stove to your room, plan the flue route, protect the floor, and leave you with a fireplace that lights easily and draws properly from day one. We also service existing installations, replacing rope seals and glass panels when they wear.

Common questions

Can a combustion fireplace be installed in an existing house?

Yes – the flue is routed through the ceiling and roof, so almost any home with roof access can take one. Double-storey and apartment installations need a site check first.

How long does installation take?

A standard installation is done in a day. Complex flue routes or masonry work can add a second day.

Do you supply the fireplace too?

Yes – we stock Hydrofire, Godin, Morso, Charnwood, Wamsler and other leading brands, and install what we sell.
