6 Best Waterproof Patio Heater Covers in 2026

The Zettum cover measures 89 inches tall with a 33 inch dome and a 19 inch base, and the listing says it fits popular heaters up to 50000 BTU from brands such as East Oak, Hampton Bay and Fire Sense. It is made from 600D oxford cloth with a polyurethane coating, which the maker describes as heavy duty, super waterproof, and softer and more breathable than PVC covers. A zipper closure makes it smooth to put on and take off.

The 600D fabric is the thickest in this group, which should resist tearing and UV better than thinner covers, and the maker says UV aging tests show it withstands at least three years. An adjustable cord buckle tightens the hem against wind. The tradeoff is that thicker fabric is heavier and can be harder to fold, and a standard 89 inch size will not fit pyramid heaters.

A portable storage bag is included, which solves the off-season problem of what to do with a bulky cover. Wipe the cover dry before bagging it, and store it out of direct sun. Compared with the QH.HOME at 500D, it uses a thicker denier but relies on a cord rather than Velcro strips. Compared with the Amazon Basics, it is a single-size cover with a stronger waterproof claim, since the Amazon Basics says water-resistant.

The QH.HOME cover is 89 inches tall with a 33 inch dome and a 19 inch base, made from 500D heavy-duty tear-resistant Oxford cloth. The listing says three retractable Velcro strips in the middle fit it snugly around the heater and keep it from forming a sail in wind. The fabric carries a UPF50+ rating and a transparent PU inner coating that resists temperatures up to 230 degrees Fahrenheit.

The Velcro strips are the standout, because a loose cover on a tall heater acts like a sail and can pull the whole unit over. A YKK zipper is described as smooth and durable, and a Velcro bottom closure replaces the drawstring so you do not have to rethread it every time. The tradeoff is that Velcro can collect lint and debris over time, and the cover is black, which absorbs heat in strong sun.

The listing says installation needs a ladder or stool because of the full-length zipper on a tall heater, so plan for that. Fasten the strips every time and check them for lint. Compared with the Zettum, it has thinner fabric at 500D versus 600D but better wind control, and it does not list a storage bag. Compared with the OutdoorLines at 420D, it adds Velcro and a thicker weave rather than a draw cord alone.

The Amazon Basics cover fits most stand-up patio heaters up to 95 inches high with a 34 inch dome diameter and a 17 inch round base diameter. It is made of 100 percent woven polyester with a laminated undercoating to minimize rain seeping through, and tough interlocking seams add strength. Click-close straps keep the cover in place on windy days.

The 95 inch fit makes it the most forgiving for taller heaters, including some that are taller than 89 inches. It is meant for everyday use and the off-season. The tradeoff is that the listing says water-resistant rather than waterproof, which is a lower promise than the PU-coated oxford covers, and no fabric denier is given.

A 17 inch base is narrower than the 19 inch base of the others, so check your heater's base diameter before assuming it fits. Clip the straps every time you cover it and dry the cover before storing. Compared with the Zettum, it fits taller heaters but makes a weaker waterproof claim and does not list a storage bag. Compared with the Easy-Going Pyramid, it is for round tower heaters, and its click-close straps are a different approach from the pyramid cover's elastic hem cord.

The Easy-Going Pyramid cover is built for pyramid torch patio heaters and measures 90 inches tall and 23 by 23 inches. It is made of oxford fabric with a waterproof backing and described as waterproof, weatherproof, dustproof and UV resistant. A full-length zipper closes it, and two padded handles make it easier to pull on.

Pyramid heaters are square and narrow compared with round tower heaters, so a standard cover would hang loose. A cover cut for the shape stays tighter and resists wind better, and an elastic hem cord with two cord locks cinches the bottom. The tradeoff is that it will not fit round tower heaters, and the listing gives no fabric denier.

An air vent reduces condensation under the cover and wind lofting, which is a real advantage for a cover you leave on all winter. A storage bag is included for the off-season, and you can clean the cover with a damp cloth or hose. You need to measure your pyramid carefully before ordering. Compared with the standard 89 inch covers, it is shaped for a different heater, and compared with the Amazon Basics it gives a snug fit on a narrow frame rather than a generous round one.

The OutdoorLines cover is a round 89 inch cover with a 33 inch dome and 19 inch base, made from 420D oxford fabric with an upgraded UV-resistant layer. The listing says it withstands a water pressure of 3,000 Pa, one of the few numeric waterproof claims in the group. A full-length zipper and an elastic hem with two cord locks make it easy to install and keep it snug in high winds.

Air mesh vents promote airflow and prevent condensation, which keeps the interior dry. The package includes a waterproof storage bag, which solves the awkward off-season problem of a cover that does not fold into anything. The tradeoff is that 420D is thinner than the 500D and 600D covers, so it may wear sooner in harsh climates, and it fits standard round towers only.

It is also the easiest to maintain, since the listing says the cover is machine washable in cold water, tumble dried on low and never bleached. Cinch the cord and store the dry cover in its bag. It comes in three sizes and three colors, so check that you pick the 89 inch version. Compared with the ANSTROUT, it adds air vents, a bag and washing instructions, and compared with the QH.HOME it uses a draw cord rather than Velcro strips.

The ANSTROUT cover is 89 inches tall with a 33 inch dome and 19 inch base, sold as a universal size for most standard patio heaters. It uses an upgraded 420D durable oxford fabric with a waterproof coating on the back, which the listing says resists rain, sun, frost, dust and bird droppings. A strong, smooth zipper and overall reinforcement stitching are highlighted.

Reinforced stitching helps seams survive wind and repeated on-off cycles, which is where covers often fail first. A drawstring around the bottom pulls the cover tight so it is less likely to be blown away, and the large opening lets one person install and remove it alone. The tradeoff is that 420D is thinner than the 500D and 600D options, and a universal size can still be loose on narrower heaters.

The cover folds very small for storage, though the listing does not mention a bag. Measure your dome and base before ordering, and dry the fabric in the sun after washing it with water. Compared with the OutdoorLines, it lacks a bag and air vents but highlights stitching. Compared with the Zettum, it uses thinner fabric at 420D against 600D, and it is the simpler, no frills option of the group.
