The 87-Inch Black 420D Oxford Pyramid Patio Heater Cover protects square propane pyramid patio heaters from rain, snow, UV exposure, dust, and debris during storage and periods of non-use. At 87 inches tall with a 21-inch width and 24-inch depth, it fits most standard square outdoor propane pyramid heaters. The cover is constructed from 420D Oxford fabric with reinforced double-seam stitching and a silver-plated undercoating that creates a waterproof barrier on the interior lining. A zippered side opening allows the cover to be put on and taken off without lifting it over the full height of the heater. Adjustable drawstring straps at the hem secure the base against wind. A 90-day return policy applies; manufacturer warranty is 1 month.
Why Customers Choose This Heater Cover
- 87-inch height accommodates most standard square propane pyramid patio heaters — confirm your heater’s height before ordering
- 420D Oxford fabric is a heavy-duty outdoor cover material — significantly more durable than standard 210D or 300D polyester covers
- Silver-plated interior undercoating adds a waterproof barrier layer in addition to the outer fabric’s weather resistance
- Reinforced double-seam stitching at stress points reduces the risk of seam failure under sustained wind and weight stress
- Zippered side opening allows installation without lifting the full cover overhead — practical for tall pyramid heaters
- Adjustable drawstring hem straps prevent wind from lifting or displacing the cover at the base
- Black finish is low-profile and suits most patio aesthetics without drawing attention
Product Highlights
420D Oxford Fabric with Double-Seam Stitching
420D Oxford fabric is a woven polyester fabric commonly used in heavy-duty outdoor covers, bags, and protective equipment. The “D” rating (denier) measures fiber thickness — 420D indicates thick, abrasion-resistant fibers significantly heavier than the 210D or 300D fabrics used in standard lower-cost covers. The double-seam stitching reinforces the seams that experience the most stress during installation, removal, and wind loading — the points where covers most commonly fail. Together, 420D fabric and double-seam construction represent a cover built for sustained outdoor exposure rather than occasional seasonal use.
Silver-Plated Waterproof Undercoating
The interior lining of the cover features a silver-plated coating that functions as a waterproof barrier, preventing moisture from penetrating through the fabric and reaching the heater surface. The silver undercoating also provides a degree of heat and UV reflectance on the interior surface. This dual-layer protection — outer Oxford fabric shedding surface water and the inner silver coating blocking any penetrating moisture — provides more reliable waterproofing than a single-layer coated fabric cover.
Zippered Side Opening
Rather than requiring the user to lift a full-length cover overhead — impractical for an 87-inch tall heater — the cover includes a zippered side opening that allows it to be placed over and removed from the heater from the side. This makes cover installation and removal a straightforward single-person task. Keep the zipper clean and free of debris for smooth operation; do not force a stuck zipper as this can damage the zipper tape.
Adjustable Drawstring Hem
The cover’s base hem includes adjustable drawstring straps that cinch around the base of the heater frame to prevent the cover from being lifted or displaced by wind. This is particularly important for tall pyramid heater covers, where the large surface area acts as a sail in wind conditions. Tighten the drawstring fully after installation, especially in locations exposed to regular wind.
Sizing – Fits Most Square Pyramid Heaters
The cover is sized at 87 inches tall, 21 inches wide, and 24 inches deep — designed to fit most standard square propane pyramid patio heaters. Pyramid heater dimensions vary by manufacturer; measure your heater’s height, width, and depth before ordering and compare against these cover dimensions. The cover should be at or slightly above your heater’s measurements for a proper fit. A cover significantly larger than the heater will not sit securely in wind.

Ideal For
- Protecting square propane pyramid patio heaters from rain, snow, UV exposure, dust, and debris during storage
- Off-season heater storage where a durable 420D Oxford cover provides better long-term protection than lightweight alternatives
- Patio setups where a black cover integrates naturally with the heater and outdoor furniture finish
- Anyone who wants zippered-side access for practical single-person installation on a tall pyramid heater
Important Information
- Measure your heater’s height, width, and depth before ordering. This cover is 87 in. tall × 21 in. wide × 24 in. deep. Confirm your heater fits within these dimensions before purchasing.
- This cover is designed for square pyramid patio heaters. It is not suitable for standard mushroom-top or umbrella-style round patio heaters.
- Always allow the heater to cool completely before covering. Covering a hot or warm heater can damage the cover fabric and creates a fire risk.
- Tighten the drawstring hem fully after installation, particularly in wind-exposed locations. A loose hem allows wind to get underneath and displace the cover.
- Keep the side zipper clean and free of debris. Lubricate with a zipper lubricant or candle wax if the zipper becomes stiff. Do not force a stuck zipper.
- The manufacturer warranty on this product is 1 month — significantly shorter than the 1-year warranty offered on most other products in this collection. The 90-day return policy provides a longer protection window than the manufacturer warranty itself.
- Spot clean with a damp cloth. Do not machine wash, as this can compromise the silver undercoating.
Frequently Asked Questions
Will this cover fit my pyramid patio heater?
This cover is sized for square propane pyramid heaters up to 87 inches tall, 21 inches wide, and 24 inches deep. Measure your heater’s height, width, and depth and compare against these dimensions before ordering. It is not designed for round mushroom-top or umbrella-style heaters.
What is 420D Oxford fabric?
420D Oxford fabric is a heavy-duty woven polyester where “420D” refers to the fiber denier — a measure of fiber thickness. Higher denier values indicate thicker, more abrasion-resistant fibers. 420D is significantly heavier and more durable than the 210D or 300D fabrics used in standard lower-cost outdoor covers, making it suitable for sustained outdoor exposure rather than occasional seasonal use.
How does the zippered side opening work?
The side zipper runs along the length of the cover, allowing it to be opened and wrapped around the heater from the side rather than lifted overhead. Unzip the cover fully, position it around the heater, then zip closed and tighten the drawstring hem. This makes installation a practical single-person task for a tall 87-inch heater.
What does the silver undercoating do?
The silver-plated undercoating on the interior lining creates a waterproof barrier that prevents moisture from penetrating through the outer fabric and reaching the heater. It also provides heat and UV reflectance on the interior surface. This dual-layer approach — outer Oxford fabric plus inner silver coating — provides more reliable waterproofing than single-layer coated fabric covers.
Can I cover the heater while it is still warm?
No. Always allow the heater to cool completely before covering. Covering a hot or warm heater can melt or damage the cover fabric and creates a fire risk. Allow at least 30-60 minutes of cooling time after use before applying the cover.
What warranty does this cover include?
The manufacturer warranty is 1 month — shorter than the 1-year coverage offered on most other products in this collection. The 90-day return policy provides a longer window than the manufacturer warranty itself. Contact us promptly if you receive a defective or damaged cover, and retain your purchase confirmation for return and warranty reference.
