Fuel and Fuel Efficiency

The heater has three settings for 30,000, 36,000, and 45,000 BTU. As a 20-pound propane tank holds 4.5-4.75 gallons of propane, you get about 2 hours per gallon or 8-9.5 hours per tank; the usage varies according to what setting you have it on. Smaller tanks also work if the connections are the same, but the hours of service will be less.

The device lacks a thermostat to indicate the actual temperature at any of the three settings.


The radiant heat it provides covers a 925 sq. ft. area. It is ideal for warming up your outdoor not only your living space at home, but also garages, fishing, hunting, camping sites, at sporting events or tailgate parties, or on loading docks or at construction sites. It is for outdoor use only.

During operation, the heater is no louder than a fan, so it will not interrupt conversation. Some hunters complain that it is too nosy when hunting, but most comment that it makes activities such as hunting in a duck blind much more comfortable.

Safety Features

This heater is safe to use outside. As with any heater, it can burn someone who touches it during operation; if a strong wind blows it over, it should turn off before it ignites any flammable materials nearby. Sitting too close to the heater in a windstorm could be dangerous. The product is not intended to be left outside at the mercy of the elements. It is easily disconnected from the propane tank so bringing it out of rain and snow is an easy way to protect it. Carrying it with the tank attached is 30 pounds or less.

The unit is not intended for indoor use as deadly carbon monoxide can build up when the heater is used in a closed setting. Even using the heater in the garage requires proper ventilation, such as an open door.

The heater should not be used in a workshop where the excessive dust could pose an explosion hazard.

Assembly may take up to an hour with a Phillips screwdriver and a socket set, but the process is easy and is well-explained in the instructions.

Fuel and Fuel Efficiency

The heater broadcasts heat to a large circle, which is great if a group is sitting around the heater talking. It has reflectors that can be adjusted with a handle to focus on the part of the circle where guests are congregating to make them more comfortable and save energy. The reflectors are very effective at doing what they are intended to do – focus the heat where you want it.

The gas can be turned down to a lower flame position for comfort and energy savings.

Safety Features

The propane tank fits in a compartment at the base of the heater. Once the heater is attached to the tank with a hose, the tank is secured in the chamber with a light chain, and the whole compartment closes with a latch. If the unit were to fall over, the tank is unlikely to fly out.

Though the heater has a weighted base (due to the weight of the propane cylinder), it has an anti-tilt design and flame failure cut-off switch for safety in case the winds are too strong. The heater is hard to accidentally knock over, but if there are tornado or hurricane warnings in the areas, roll it to a sheltered area.

The heater should be used outdoors but can be used in a well-ventilated porch or garage with a minimum of 30% of its surface area open. If it is used on a screened-in porch, it should be 40" from the screens. This unit is not recommended for use under awnings or fabric sun shade, pergola covers, or canopies. The heater should not be left unattended.
The Hampton Bay brand is Home Depot's own, so the $199 price is at least $100 better there than elsewhere.

Comparison To Other Products

The Hampton Bay 38,200 BTU heater is highly rated at Amazon and at Home Depot who owns the Hampton Bay brand. Aside from complaints about the product performance, many buyers had issues with the packaging or found that parts were missing. Though this is a Home Deport product, the company does not stock replacement parts, so the buyer has to contact a service sent and wait.


The heater is an attractive one for patios. As long as you do not overpay, the heater with its reflectors is a good buy.

Factors to Consider When Buying the Best Patio Heaters

When selecting the best patio heater, your goal in heating the area is key to your selection. Do you want to give warmth and ambiance to an outdoor dining space or warm up a group on a job site or tailgate party? Will you want to warm 6-8 friends or a larger crowd? Do you live in a climate where the heater will have to raise the temperative by a few degrees to take the chill off or raise the temperature significantly?

For a small patio, where people will be eating at one table, a tabletop heater may be just right for you. When you want your heater to serve as the focal point of your yard, a fire pit is definitely the best option.

With these parameters in mind, patio heater selection comes down to these qualities:


Heater styles and design range from industrial to elegant. Some models are intended to perform their job without regard for looks, while others are intended to be a style element in the room. Our top-of-the-line brand, the Italian-made Lightfire, is a show-stopper that is part patio heater, part work of art.

Type of Fuel and Fuel Efficiency

The heaters considered in this buying guide are fueled by propane or natural gas and are intended for outdoor use in a well-ventilated area. Their output is measure in BTUs.

Some gas heaters have electric starters that are battery-powered.


Patio heaters are intended to warm people within a certain range. Those that serve a small range may be intended for a small conversational group with the patio furniture pulled close together, while those with a broader range might improve the comfort of a number of diners in a restaurant.

Heat Output and Performance

The more powerful your heater is, the more space it heats. The measurement of the power of a heater is in British Thermal Units (BTUs). In which, the more the BTU, the bigger its heat output, and thus, range.

How far the best can go is also dependent on many other factors such as the degree of cold outside. In comparing different models to each other, you can use measures like BTUs and wattage, although they could be misleading sometimes.

Also giving heed to what customers say in their review about the product is very important too as they speak from experience.

Tip: A heads-up; price typically increases as BTU increases.

Safety Features

There’s always a risk with any product, heaters inclusive. And the most common risk for patio heaters is when they tip over during windy days.

Most gas heaters do not have a pilot light, but they are very hot and may have a flame. While there are some basic safety rules to follow when congregating near a gas heater, heaters may have weighted bottoms to preventing them from falling over easily, automatic shutoffs if they go out, and other safety features to reduce risk.

Therefore, if you live in a very windy area, you should consider buying a model that offers these features or find a way to secure the heater.

If your space is enclosed, the best option is to make use of an electric heater.


If you want a heater to warm up a deck or keep you comfortable on a hunting trip, you may want to only spend up to a couple hundred dollars. Your budget may be five to ten times that if you want to make outdoor dining appealing to a larger group of people.

Buying the cheapest product you can find may not be a good move as safety is involved. Many heaters have similar features, though, so if you look to find a heater that has the features you want, you still may be able to save.


81RGIL7irzL. SL1500

Other Features to Consider

Patio heaters can be heavy to move, as propane tanks used to fuel them weigh them down. Many heaters have wheels built-in or come with an additional trolley. Not all wheels are well-made, so verifying that a model you like has good well will come in handy on a windy day when you need to move the patio heater to a sheltered area. Moving is not recommended until the heater has cooled down.

Some heaters have additional accessories such as mounts, controls, and reflectors available. Before buying a heater, you will ideally acquire what you need to install and use the unit, but you should at least check about the availability of accessories or replacement parts.


Frequently Asked Questions

1. How long does it take to set up a patio heater?

Most of the time, setting up a patio heater is straightforward, and it only takes a few minutes. It also doesn’t require any skill, and all you need is a few household tools and the instructions manual to get started. Some heaters may require up to an hour of assembly time, but ascertain that the job is manageable, even if it takes some time.


2. Are patio heaters safe to use?

As long as you use a patio heater outset or in a well-ventilated area, you should be safe with a gas heater. Make sure the heater is secured so it doesn’t fall down or is not positioned so others will bump into it. Keep any flammable materials the recommended distance away.

3. How do you select the right size patio heater?

Figuring out the number of BTUs or even the number of heaters you need depends on the size of the area to be heated and how cold it is.

Multiply the length x width x high of the area to be heated. If you are measuring for an uncovered patio, assume 7′ is the height. If you are buying heaters for a 20′ x 20′ patio heated to 7′ about the ground, the cubic feet is2800

Subtract the current temperature from the desired temperature and multiply the remainder by the cubic feet. If you want to heat it to 75° from 45°, you multiply the difference of 30° x 2,800 and get a product of 84,000. Your heaters should have a combined output of 84,000 BTUs.


Having a patio heater can enhance your enjoyment of outdoor space, so picking the right one for your needs is important. Our buying guide will direct you to the best patio heater on the market with features you’ll love.
