We have listed the best propane garage heaters on our list. But it does not make it easy to choose a product online. It is essential that you must take into consideration a few important factors to make a viable choice. This is the way to make sure that the propane garage heater you pick precisely meets your requirements and best serve your interests and needs.
Portable vs. Mountable Propane Heaters
The propane heaters are wither portable or mounted. The heater can be mounted on the floor, ceiling, or walls. These installation options have their own benefits and disadvantages and it depends entirely on you that which kind of model you want to select.
The portable garage heaters let you place the heater at any place or location as per your convenience. It is better to consider the BTU of the portable heater and a perfect location for its efficient use. For example, if you want a heater for outdoor use, you may pick one designed for outdoor use. However, to warm the different spaces in your home or camping tents, you can pick a propane heater for indoor or outdoor use.
The mounted propane garage heaters can be wall-mount, installed on the ceiling, or fastened to the floor. You must check the installation option that best meets your requirements. Pick an installation option that precisely caters to your desired location.
Forced-Air vs. Radiant vs. Convection Propane Garage Heaters
A radiant heater heat objects directly. For this reason, the effectiveness depends on the area where it is placed or positioning in the room. The good thing about such heaters is that they are free from noisy fans and retain the heat for a longer time. However, in order to avail of maximum heat you have to place them at an appropriate position.
The forced-air heater uses propane gas to generate heat and the heat is evenly distributed in various directions. Such heaters are portable, heats up surrounding environment, and generate plenty of heat. However, they may have a noisy fan.
A convection heater generates heat in the form of blue flame. They are also called as vent free heaters. They are integrated with a small fan and gently blow air across the heat source. The hot air is circulated across directions. The heat level generated is lower than other kinds of heaters, but they deliver more efficient and widespread performance.
Understanding BTU or Heat Output Rate
The full form of BTU is the British thermal unit which is the standard measurement unit for heat energy in the system of Imperial Units. This is the standard measurement system is based on the specific object’s ability to generate the volume of heat, which is essential to raise the temperature of one pound water by one degree Fahrenheit. BTU is used to measure the heat efficiency of propane heaters.
When checking the BTU range for a propane garage heater, you must take into account the BTU needed by your garage to achieve the desired purpose. Sure you would not want to overheat the space or end up having inadequate heating.
Here are a few steps you can follow to measure the BTU per square foot to identify the relevant propane heater.
Step 1 – Calculate the Total Square Footage
You have to calculate the square footage size of the area where you want to setup the propane heater. For this, you first have to consider the shape of room or floor. This shape can be then used to calculate the square footage.
For a square or rectangle shaped room, multiply the length by width.
For a circular shaped room, multiple 3.14 by the radius or distance from the center of the space.
For a triangular shaped room, multiply length by width and divide the answer by two.
Also, it is possible that your room is not built in a proper conventional shape. In such a case, you must divide the space into adequate shapes to make your calculation easier.
Step 2 – Evaluate the Heat Capacity for Per Square Foot
The BTU range mentioned on the propane heater must be multiplied to the square footage calculated by you in the first step.
Usually, the BTU range mentioned on the heater is calculated on units per hour. The final estimated figure is the amount of heat energy covering each square foot for the intended room in one hour.
The BTU range for propane garage heaters may vary from 4,000 to 125,000. It is the volume of heat energy released by distinct heaters and determines the room size for most effective results.
While making such estimations, ensure that warm air do not sweep into through holes or leaks in doors. For this you must prevent garage door insulation by checking all cracks and leaks.
Determine Safety Features
Propane garage heaters are engineered to offer you absolute safety. The important safety features that a heater must possess are:
Topple / Tipple Over Cut Off
Heaters with naked flames usually generate high temperatures and must be knocked over. The naked flame has a risk of someone being burned. The tipple or topple over cut off can prevent such dangers as this feature cut off heat generation when tipped over accidentally.
ODS or Oxygen Depletion Sensor
Propane garage heaters can release small volume of carbon dioxide, which can be very dangerous, especially in an enclosed space. The ODS feature eliminates this risk by detecting automatically lower oxygen levels in a room or garage.
High Temperature / Overheat Cut Off
This safety feature activates when the temperature sensor of heater reaches maximum safety level. It eliminates the risk of severe burns and reduces the risk of materials that may combust due to high temperature.
The warranty for a heater showcases the manufacturer’s confidence in their product. A product backed with rich warranty is designed to last long and deliver high performance. If there is a situation when you are confused between two products with almost similar quality, you can pick one with better warranty conditions.
While searching the best propane heater, you must consider its runtime as well. There is an indirect relation between the BTU and runtime of any propane heater. A propane heater with high BTU is expected to deliver lower runtime while the propane heater with lower BTU is expected to deliver high runtime.
Heat Control Levels
Most of the propane garage heaters come with varying levels of heat control, which is usually in the form of control knob, control dial, or buttons at the side of the heater.
While basic heaters offer three range heat levels control, including low, medium, and high, the advanced models may offer multiple settings.
In addition to heat level controls, you can also check for air flow outlet or control.
Frequently Asked Questions [FAQ]
Are propane heaters better than Kerosene heaters?
Kerosene and propane are excellent choices of fuel for heating. Both of them are readily available. However, propane is preferred over Kerosene because it burns clean and delivers odorless heat generation. Kerosene heaters are less expensive than propane heaters.
Are propane heaters safe for use in a garage?
Yes, it is absolutely safe to use propane heaters in a garage. Just make sure you pick a model with advanced or multiple safety mechanisms. Additionally, you must follow security measures like keeping combustible items away from the heater, checking leaky holes in a heater, and more.
Do propane heaters deliver noisy or quiet operation?
The propane heaters are specially designed for noise-free and quiet operation. If there is any kind of noise you experience, you must check for its cause as it can be because of some problems within the propane gas tank or air circulating fan.
How do propane heaters work?
Propane heaters use propane gas as a fuel to generate heat. The fuel is usually stored in a tank in the liquid form and the heater transforms this liquid into hot gas form. For heating, the heater is connected to a tank. Small propane heaters are built-in with smaller tanks.
What is the minimum BTU range required for a 500 square foot garage?
A propane heater with a minimum BTU of 16,000 to 20,000 is ideal to warm up a 500 square foot area. There are a few such models mentioned in our list.
Can propane garage heaters lead to a fire hazard?
It is true that propane is a highly flammable substance that involves a potential risk of causing fire and explosion. Hence, it is essential to take necessary precautionary measures to avoid accidents or fire hazards. Make sure there are no combustible materials placed nearby or gas leaks.
What ventilation is required to safely use a propane garage heater?
