Things We Love:

Efficient and Versatile

Sunpak S-Series patio heaters are among the best on the market in terms of both performance and style. They use either propane or natural gas to produce infrared heat, which gives them an edge over traditional patio heaters. By using infrared heat, S-Series units send out safe but directional heat waves that warm people and objects rather than just nearby air, and their aluminum grill guards aid in weather resistance. These outdoor heaters are available in 25,000 BTU and 34,000 BTU models which can heat areas of about 100 square feet and 140 square feet respectively.

With that efficient heating power come several design options that can be tailored to fit the décor of your outdoor space. All S-Series heaters are 48 inches long, but you can pick between a 304 stainless steel or black powder-coated finish depending on your aesthetic needs. Your can further customize your sleek Sunpak heater with trim kits in bronze, black or stainless steel. For your convenience, S-Series units can be easily positioned on your wall or ceiling thanks to an included mounting kit.

Safety-First Design

When it comes to patio heaters, perhaps the only thing more important than performance is safety. Sunpak had that in mind when crafting its S-Series models that sport flame sensor features and automatic re-ignition. If the heater detects that the flame has gone out, it will attempt to re-light three times before shutting off the gas to prevent waste or potential harm to you and your guests.

These heaters also operate on electronic ignition that puts you in control with a simple push of a button. They even come with a 120-to-24-volt transformer so you can plug them directly into a standard outlet. Thanks to these safety features, you can have peace of mind while enjoying the warmth from an S-Series heater on a chilly evening.

Things To Consider:

Because S-Series models don’t include vents, they can’t be recess-mounted and must be installed in a well-ventilated area with a continuous supply of fresh air. Remember to always consult a licensed plumber and electrician for installation. These units carry a 90-day commercial warranty and a one-year warranty for any residential use.

Hi Debbie. Your best bet would most likely to get multiple heaters to evenly cover the space.

Asked by DebbieAnswered by Joey

How do you know what size BTU heater to get? our area is about 16x20 ft. it is a summer room that can be enclosed with vinyl shades. any issue with running while the shades are down in terms of exhaust?
Was This Helpful?
Hi, thanks for asking. The number of BTUs determines the intensity of the heat being produced. Higher BTU amounts will produce more intense heat that will carry further in an area. We don't recommend using this heater indoors or behind shades as the natural gas will not escape as easily and can cause damage or harm.

When will my item arrive?

Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we’ve all come to expect for small parcels, so it’s important that you’re prepared and understand what’s required of you well before delivery day.

  • Most freight products ship on a pallet
  • Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
  • We’ll specify which process you can expect in your shipping confirmation email.

For carriers that schedule delivery appointments:

Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can’t be held responsible for damages that occur during delivery. As complicated as this process may seem, we’ve only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.

For carriers that deliver without an appointment:

Carriers that deliver without an appointment don’t require you to be home or set up a delivery window, and you aren’t required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you’re home at the time of the drop-off, you can request the driver place your delivery in the garage; if you’re out of the house, the driver will leave it near the garage or doorstep.
