Heikō Fire Pit: a chunky off-set concrete fire pit in 18 finishes
The Outdoor Plus Heikō fire pit is a low gas fire pit with a thick, chunky rim and slightly angled sides in an off-set shape that is not quite a rectangle. It measures 58.5 by 44.5 inches, is cast in the USA from GFRC, a lightweight glass-fiber concrete with the look of stone, and comes in 18 finishes.
Order it for natural gas or propane. Light it with a match, or add electronic ignition and start it with a button. The burner, pan, hose, and fittings are included; a key valve, cover, stainless lid, and fire glass are optional. Prefer a straightforward rectangle? See the Pismo concrete fire pit. The Heikō fire pit ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What are the dimensions of the Heiko Fire Pit?
A single, considered size: 58.5 by 44.5 inches (SKU OPT-5844HK). The Heiko is not a pick-your-length series — it is one sculptural GFRC concrete form, scaled to anchor a seating group on its own. If the proportions fit your space, nothing else in the line looks quite like it.
How many GFRC finishes does the Heiko offer?
Eighteen — the full The Outdoor Plus GFRC palette, from cool Ash, Natural Gray, and Silver through earthy Brown, Chestnut, and Moss Stone to warm Copper, Bronze, and Vanilla. On a form-driven piece like the Heiko, finish selection is half the design decision, so sample against your hardscape.
Which ignition systems come with the Heiko?
Five, with Plug and Play Ready (CSA certified) on the list alongside Match Lit, Match Lit with Flame Sense (LC certified), Flame Sense with Spark, and Low Voltage Electronic (CSA certified). A Heiko with electronic ignition keeps the sculptural experience seamless — no ritual unless you want one.
How much heat does it generate?
Full gas-fire heat — flame cores beyond 1,000 degrees Fahrenheit, radiating a comfortable warm zone around the Heiko 58.5-inch body. GFRC handles the thermal cycling without complaint, and the key valve lets you slide between a low sculptural flame and genuine cold-night warmth.
Is GFRC light enough for elevated decks?
That is GFRC signature trick — the Heiko has the visual mass of cast stone at a fraction of poured-concrete weight, which makes deck and rooftop placements plausible where true concrete is impossible. Confirm structural capacity, use a non-combustible surface, and follow the spec sheet clearances over wood.
Can it be installed under a roof or pergola?
Only where the structure is genuinely open and tall enough to satisfy the Heiko clearance requirements — heat and combustion byproducts need an unobstructed exit. Check the specification sheet, then confirm with your local inspector. If the margin is thin, open air placement wins.
Which fuel do I order?
Liquid Propane or Natural Gas — declared at purchase, since every Heiko is built to that order like the rest of our concrete fire pit collection. For a permanent sculptural installation, plumbed natural gas is usually the fitting choice.
