Considerations Before Buying A Vented Propane Heater 

Here are a couple of key factors to consider when shopping for your vented propane heater.

Heat Output (BTU)

BTU which means British Thermal Unit is a way of measuring energy. 

One BTU refers to the load of energy required to increase the temperature of one pound of water by one degree. With relation to your heater, the BTU rating indicates how powerful your unit is, and it signifies just how much energy it can process to heat your room. The higher the BTU rating of your heater, the more powerful it is. 

How much heat output you’d require will depend on the size of your space. If you have a bigger space, it’d be more advisable to get a heater with a high BTU rating.

Thus, you may want to calculate the area that you’ll need to heat before making your purchase. That way, you can judge whether the BTU output of the heater would cover the area that you need to heat.

Many heaters will divulge information concerning the area size they are suitable for. Plus. they also give an approximate BTU rating.

With such information, you can then decide whether the heater will be sufficient for your needs.

Steps In Calculating Your Heater Size

The basic formula to determine your heating needs is (0.133 x total cubic feet of space x desired temperature change). This will give you the total BTU’s you’ll require per hour.Calculate the total cubic feet of your space by multiplying the length, width, and height of the room you want to heat.Thus, if you have a room that’s 10 feet long, 12 feet wide and 12 feet high, your area would be 1440 cubic feet (10 x 12 x 12)Subsequently, you ought to figure out your desired temperature increase by subtracting your cold outdoor winter temperature from your preferred indoor room temperature. Therefore, if your area’s winter temperature averages a low of say 15 degrees Fahrenheit, and you prefer a temperature of 68 degrees Fahrenheit, you’ll need a temperature increase of 53 degrees Fahrenheit.The next thing is to multiply the figure of 0.133 by the desired temperature change as well as by the total cubic feet of area already determined. This measurement (rounded off) will give you the total BTU or heater size appropriate for your space.Thus, from our earlier calculations, our total BTU would be 1960 x 53 x 0.133 which will give us 10,150.56. Rounding this sum off would mean we’ll need a heater of 10,000 BTU’s to provide us with the temperature we prefer indoors.

You can also use our Heating BTU Sizing Calculator to get a more accurate size of vented propane heater.

Safety Features

Propane heaters could be hazardous. Because the fuel, propane, is flammable, the slightest malfunction of the heater could trigger an accident. Since we want you to enjoy complete peace of mind during usage, we’d advise you to stick with an indoor propane heater with an abundance of inbuilt safety options.Pertinent safety options include the:

  • Tip Over Safety –  An anti-tip over switch allows your heater to automatically stop running when knocked over accidentally.
  • Inbuilt Overheat Protector – The unit will shut off if it begins to overheat.
  • Oxygen Depletion Sensors – This feature leads to the immediate deactivation of the heater anytime oxygen levels are low.

Thermostat Options

Thermostats allow you to accurately control your home’s heating temperature.

This feature not only makes for a more comfortable ambience, it also helps reduce your overall energy costs.

Though not all vented propane heaters are equipped with inbuilt thermostats, it’s especially rare to come across modern vented propane heaters that don’t come with one. 

Yes, vented propane heaters with programmable thermostats cost more. Yet, in the long run, you’d end up saving chunks of energy costs as they provide the option of reducing heat output especially when it isn’t needed. We’d therefore advise that you stick to heaters that come with a thermostat.

Mode of Heat Production

Heaters make use of a variety of methods of operations to provide warmth. These include:

  • Radiant Heating System

These systems don’t have to warm the air. They produce heat waves that only warm objects that the rays come into direct contact with. They produce no noise and will be great for offices or bedrooms.

  • Convection Heating System

These circulate warm air using a fan. 

They’re more likely to increase the temperature of much larger spaces than the radiant heater can. They’re much noisier anyway.

Considering the fact that a convectional heating system will have to slowly warm the air within an area before transferring heat, they are considered less efficient than radiant heating systems. This is because air absorbs heat quite poorly and heat may easily be lost if your insulation is poor.

With radiant heating systems providing concentrated beams of heat which will uninhibitedly be absorbed by their intended target(s) very quickly, such units are more efficient.

However, they’re more suitable for warming smaller areas. Thus, if you want the provision of sustained heat over an extended period of time in a larger space, you might want to go with a convectional heating system. Otherwise, stick with a radiant heater for its better efficiency.


Heaters come in a myriad of shapes and sizes. If you move around a lot, you might want to consider one that is smaller and portable.While they are easy to move around, they also eliminate the need for power cables.These days many heating units come with wheels or handles. You may want to lean more towards a heater on wheels if you can’t afford to strain your back lifting especially if the heater is filled with fuel at the time.Should you desire to transport the heater around often, you should check the product description to make sure that it is not too heavy to carry. 

Heating Costs

How much you’ll spend on a monthly basis will depend on the BTU on the heater as well as the size of your space. With knowledge about the market rate for propane gas, you’d be able to figure out your monthly heating costs easily.

The unit price of propane is about USD 2 per gallon. We’ve already established that it takes about 100,000 BTU to exhaust one gallon of propane. 

If your heater produces 20,000 BTU per hour for 10 hours a day, and it costs $2 per hour to operate, you’ll pay about $4 a day to run your heater.

Tips For Using Propane Heaters

You need to know how to use your propane heater right. Follow these safety tips when using a vented propane heater.

Keep Heater Far From Combustible Materials

You should always position your heating unit far from flammable materials. These include curtains, towels, bedding, and the likes.If you wish to mount your heater on a wall, take care that the wall material is not combustible. Again, be sure not to spray deodorants, hair sprays, or air fresheners near your heater.

Install Carbon Monoxide Detectors 

Some propane heaters don’t come with an oxygen detection sensor to detect when oxygen levels are low. 

If you’ll use such a heater indoors, make sure to have a carbon monoxide detector installed.

Read Manual Instructions

You need to familiarize yourself with instructions provided by the manufacturer of your small vented propane heater.

There, you’ll find pertinent information regarding installation and usage. Furthermore, you’re likely to find instructions on how to curb hazardous situations like when there’s a leakage.

Have a Regular Delivery Schedule

A regular delivery schedule of propane gas will ensure you don’t completely run out of gas till the next refill date.

If you allow the tank to completely run out of gas before the next refill, it may result in leaks after the system has been refilled.

Furthermore, there’s likely to be the infiltration of air or moisture into an empty tank. This could result in the buildup of rust.

Have Your Heater Inspected Regularly

To ensure consistent, long-lasting performances of your tank, engage the services of a specialist tol inspect and service your heater annually.

Follow the instructions below:

  • Choose the location you’d hang the propane heater.
  • Drill the holes at the position you will mount the heater
  • Remove hardware from plastic wrapping
  • Secure hardware unto wall using screws
  • Create a hole in wall through which propane hose will go
  • Place heater onto brackets
  • Insert propane hose into hole to connect heater to the gas tank outside
