Best Vented Propane Heater in 2021

Find the best vent propane heater for your home!

When it comes to heating your home during those chilly winter months, sometimes your central heating just won’t cut it by itself. Cranking the thermostat up wastes energy heating your whole house instead of targeting the room you spend the most time in. Energy prices are only climbing higher and higher, so your bills can quickly spiral out of control!

A vented propane heater is a great alternative! Vented propane heaters are powerful, energy-efficient, and heat spaces quicker than many other types of heaters out there. They’re also super-easy to install because they don’t use any ductwork!

Read on to learn what to look for when buying vented propane heaters for homes.

I’ve worked as a licensed heating, ventilation and air conditioning (HVAC) engineer for over a decade. I’ve used everything I’ve learned in that time to put together this essential vented propane heater buying guide. I’ve also picked out 5 of the very best vented propane heaters your money can buy today.

First, let’s take a look at the different types of vented propane heaters you’ll need to choose from.

Types Of Vented Propane Heater

There are two types of vented propane heaters, B-vent and direct vent. The venting system that’s right for you will depend on your needs and the room you’re going to heat.

B-Vent

B-vented heaters use fresh room air from inside your home for combustion and then vents it outside. It uses a chimney of sorts, but not the heavy, old-fashioned stove-type you may be imagining! A B-vent chimney is much smaller and easier to install. 

They generate a lot of heat quite quickly, and they’re popular with homeowners for their large and visible flames that add character, ambiance, and warmth to the room.

Direct Vent

Direct vent heaters work in a similar way to B-vent heaters, but they draw air for combustion from the outside instead. They don’t need an obtrusive chimney to work, using a small hole that can be drilled into the wall it’s fitted onto to vent exhaust fumes.

Direct vent heaters are generally more energy-efficient than B-vent heaters, so you’ll save money off your monthly energy bills. Direct vent heaters are an exceptionally safe heating option because they’re a tightly-sealed system and don’t use any indoor air.

Vented Propane Heater Buying Guide

When you go shopping for your vented propane heater, you should consider the following factors. Doing so will ensure you’re getting the right vented heater for you at the best possible value!

Heat Output

The heating output of a vented propane heater relates to how quickly and effectively it can heat a space of a specific size. Heat output is measured using British Thermal Units (BTUs). The higher the BTU rating of a heater, the more powerful that heater is. 

With this in mind, it’s important to choose a vented heater with the right output for your home. One with a BTU rating that’s too low will mean you won’t be able to heat a space as well as you might expect. A rating that’s too high could make the space uncomfortable and needlessly add extra dollars to your monthly energy costs

If you want to heat a larger space, you should look for a vented heater with a higher BTU rating. That way, you’ll know it’s powerful enough to cover that area. It’s even possible to work out the exact BTU rating you’ll need.

Calculating Your Heater Size

It’s a good idea to use this formula to give you an accurate idea of the size of the vented heater you’ll need. Don’t worry if you didn’t do well at math in school; it’s easier than it sounds!

First, measure the cubic footage of the room you want to heat by multiplying its length, width, and height together. If your room is 10 feet long, 10 feet wide, and 10 feet high (10 x 10 x 10), your room would be 1,000 cubic feet. 

Next, work out your desired indoor temperature increase. Just subtract the cold outdoor temperature from your preferred indoor temperature. If your outside winter temperature averages around 15 degrees Fahrenheit, and you like a cozy indoor temperature of 68 degrees Fahrenheit, your desired indoor temperature increase is 53 degrees Fahrenheit.

Finally, multiply 0.133 by your desired temperature change and the cubic footage of the space you want to heat. Using my examples, you’d multiply 1,000 x 53 x 0.133 to get the figure of 7,049. Rounding up, you’d need a heater with 8,000 BTU’s of heat output to get your desired indoor temperature!

Safety Features

Because propane heaters use flammable gas to operate, misusing them can create a fire hazard. Fortunately, many modern vented propane heaters are fitted with multiple safety features that let you run them with complete peace of mind. 

The best vented propane heaters will use at least one or more of the following safety features:

Tip-Over Safety

Anti-tip switches shut the unit off if it’s accidentally knocked over, usually by 45° or more. This is a great feature if you have kids or pets running around your home.

In-Built Overheat Protector

Overheating is an especially dangerous fire hazard. A unit with an in-built overheat protector will shut down before this happens, so you don’t have to supervise the heater constantly.

Oxygen Depletion Sensor

A normal and safe room oxygen level is 21%. A heater with an Oxygen Depletion Sensor (ODS) will switch itself off if it notices that oxygen levels have dropped from 21% to a minimum of 18%. Oxygen will always stay at a safe and healthy level.

Thermostat Options

A vented propane heater with thermostat gives you precise control over your indoor heating temperature. Not only does this mean that you can tailor your heater to provide your perfect desired temperature, but it can reduce your energy costs too. 

Most modern vented propane heaters will have a thermostat built-in, but make you double-check before you buy, so you don’t inadvertently purchase one without!

A programmable thermostat is even better and will reduce heat output when it isn’t needed. Heaters with this feature may cost more upfront, but in the long run, they can save you hundreds of dollars off your energy bills!

Mode Of Heat Production

While all vented propane heaters use liquid propane as fuel, they can use different methods of generating heat. Some of these will be more suited to your needs and the room you want to heat than others. 

Radiant Heating System

A radiant heating system uses thermal radiation to heat the floor and objects in a room. As these warm up, you’ll notice the indoor temperature rise too. Because they don’t need a fan to distribute heat across the room, they operate near-silently, making them a great choice for your bedroom or office space. 

They’re very energy efficient but not as effective at heating larger spaces as a convection heating system. If you’re looking to heat a smaller space, a radiant heater may be best for you.

Convection Heating System

A convection heater circulates warm air around the room using a fan. They’re more effective at heating larger spaces than radiant heaters, but they do so less efficiently and can cost more to operate in the long term.

They’re still a great choice if you want to heat a larger space over an extended period. Just bear in mind that the internal fan can make them a little noisy, so they’re not the best option for spaces you use to work, study, or sleep. 

Portability

If you plan on moving your propane heater around from room to room quite often, it’s worth considering a unit designed with portability in mind. They’re not just easy to pick up or push around, but they also don’t need to use power cables, and that gives you plenty of freedom when it comes to placement.

Heavier vented propane heaters will often be fitted with wheels for easy portability. Iron castor wheels are best because they’re robust and unlikely to buckle or break. If the portable vented propane heater you’re considering doesn’t have wheels, then make sure you check its weight before you buy. You don’t want to put your back out moving a big heavy heater around!

Heating Costs

The cost of using your vented propane heater will depend on a couple of factors. A higher BTU heater will usually cost more to fuel, and heating a larger room consistently will add to your bills too. 

Propane currently costs around $2 per gallon, and each gallon of propane can give out 100,000 BTUs of heat. That means if you run a 10,000 BTU heater for 10 hours each day, you’ll pay around $4 a day to run your heater. Try working out how often and for long you’re going to use your heater to decide if the daily or monthly costs are affordable.

Vented Propane Heater: Frequently Asked Questions

How Long Will My Propane Heater Last?

The best vented propane heaters should last at least 15-20 years. With proper maintenance, a direct vent heater could last even closer to 30 years. 

Do Vented Propane Heaters Need Electricity?

Direct vent propane heaters need little or no electricity to run. Propane gas heaters offer more heating efficiency than electric heaters, so you’ll keep your energy bills low when you need the temperature high.

How Much Propane Does A Direct Vent Propane Heater Use?

A direct vent gas heater will consume around 1 gallon of propane for every 100,000 BTUs of heat output. A 10,000 BTUs direct vent wall furnace will run for about 10 hours using 1 gallon of propane, depending on the size of the propane tank.

How Are Propane Heaters Vented?

Ventless propane heaters don’t need to be vented, but a direct vent gas furnace does need ventilation. Such a heater needs to vent exhaust fumes outside using a small hole that can be drilled into the wall behind the space heater.
