What pushes the price of gas fireplace installation up
- Flue runs with bends, upper floors or a roof exit
- A new gas line plus the certificate when no gas point exists
- Builder or tiler work for built-in surrounds and recesses
Types of gas fireplace installation
| Type | Best for | Keep in mind |
|---|---|---|
| Flueless wall-mounted | Flats and open rooms with a vent opening | Not allowed in bedrooms or bathrooms |
| Balanced-flue | Smaller or closed rooms and bedrooms | Needs a wall or roof flue route |
| Freestanding | Easy to reposition, little building work | Takes floor space and needs a hearth |
| Built-in or insert | Flush finish in a wall or cabinet | Needs a builder or tiler for the surround |
| Double-sided | Open-plan homes heating two rooms | Highest price and needs a shared wall |
Gas fireplace materials and specs compared
| Material | Strengths | Watch out for |
|---|---|---|
| Oxygen depletion sensor | Cuts gas if room oxygen drops | Does not replace proper ventilation |
| Flame failure device | Shuts gas if the flame goes out | Confirm it is listed on the unit |
| Twin-wall insulated flue | Safe route through wall or roof | Full flue systems add R6 000 – R22 000 |
| Stainless steel body | Common on wall-mounted units | Ask which stainless grade is used |
| Output of 4–9 kW | Covers most mid-range wall-mounted units | Open-plan rooms may need more |
| Regulator rating | Some 9–12 kW units list 2 kg/h | Check the unit's manual before buying |
Sizing and gas use
- Allow about 1 kW per 10 m² in well-insulated rooms.
- Older brick homes with no ceiling insulation need nearer 1 kW per 8 m².
- A 6 kW fireplace burns roughly 0.45 kg of LPG per hour.
- Flueless fires heat poorly in double-volume rooms, so mention high ceilings.
Flue and ventilation
- Flueless models need a permanent, unobstructed ventilation opening in the room.
- Flueless units are barred from bedrooms and bathrooms, unless fitted into a chimney stack.
- Balanced-flue units use one co-axial pipe for fresh air and exhaust.
- Ask which wall or roof exit the flue will use, in writing.
Gas supply and certificate
- Confirm the unit is rated for your gas, LPG or natural gas.
- Flexible hoses through walls and wrong copper pipe fail certificate inspections.
- Check the manual's minimum cylinder and regulator size; some installers advise 48 kg. If the same cylinder also feeds a gas stove, check its cylinder rules too.
- Keep your invoice and certificate, as warranty claims can require both.
Approval for gas fireplace installation
- SANS 10087-1 requires the installer to test the work and issue a certificate before use.
- Cutting a new flue opening or wall recess may need building control sign-off. Ask your municipality.
- In sectional title schemes, get trustee consent before any external flue is cut.

Practical gas fireplace tips
- Book a gas leak test and burner check once a year.
- Tell installers your wall type, as it limits wall-hung positions.
- Get the flue route priced before you pick a model.
- Flue runs with bends cost about double a straight wall exit.
- Some insurers can reject fire claims when a gas certificate is missing.
- Ask for a written installation warranty; one supplier offers 1 year.

Frequently asked questions
What does a gas fireplace cost installed?
Expect about R11 500 – R21 000 for a flueless wall-hung unit and R21 000 – R42 000 for balanced-flue. Built-in and double-sided models cost more.
Must a gas fireplace installation come with a certificate in South Africa?
Yes. A SAQCC Gas installer must test the work and issue a Certificate of Conformity under SANS 10087-1. The same certificate rules apply if you add a gas hob later.
Should I choose a flueless or balanced-flue fireplace?
Flueless suits larger, ventilated rooms. Balanced-flue suits smaller or closed rooms and bedrooms.
Is a gas fireplace better than a wood fireplace?
Gas needs no chimney sweeping or ash clearing, but wood is usually cheaper to run. A 6 kW gas unit uses about 0.45 kg of LPG an hour.
How big a gas fireplace do I need?
Allow about 1 kW per 10 m² in an insulated room, or 1 kW per 8 m² in older brick homes. Open-plan rooms may need more.
