6 Most Efficient Propane Heater

Propane Vs Electric Heat

Propane is one of the most efficient and reliable sources of heat for your home. The following is a brief comparison of propane and electricity as sources of heat for your home.

The comparison shows that propane is better than electricity for heating homes in several ways.

  • It is easy to compare the costs of using electricity and propane for heating homes by looking at the figures provided by the US Department of Energy. Currently, the figures show that propane is 30% cheaper than electricity. If it is assumed that propane-burning heaters run for the same time as electric ones, then the cost of using propane-based heaters is 30% of that of electric heaters.
  • The safety of propane burning heaters is better than that of electric ones by far. The preparation, packaging, storage, sale, and use of propane gas takes place under the guidelines developed by the National Fire Protection Agency and industry-specific regulatory bodies. Moreover, propane heaters are safer than electric ones because they have several inbuilt safety features.
  • The performance of electric heaters depends on the level of reliability of the supply of electric energy. If there is an outage of electric power, then you cannot use your electric heater. However, propane is easily bought and stored at home. Therefore, the supply of propane gas is more stable and reliable than that of electric power. Using propane heaters is, as a result, more reliable and predictable than electric heaters.
  • Propane is a more valuable source of heat than electricity because propane heaters last longer than electric ones. Electric baseboard heaters, some of the most valuable types of heaters that utilize electricity, can last for as long as 10 years. However, the average lifetime of a propane heater is 20 years. These figures show that if you would like to get value for your money, then you should go for propane heaters.
  • Propane heaters are more effective than electric ones in terms of heating indoor and outdoor spaces. A typical electric heater provides heat that averages 98 degrees Fahrenheit. Interestingly, propane heaters provide heat that ranges from 130 degrees Fahrenheit to 140 degrees Fahrenheit. These figures show that a propane heater is the right choice for providing effective heating in indoor and outdoor spaces.

Propane Heater Safety

It is possible to use a propane heater for a long time without accidents. To achieve this objective, you need to observe several safety tips when buying and using a propane heater.

Here are a few tips to help you maintain a 100% safety record when using propane heaters.

  • Choose indoor heaters that have inbuilt safety features. Some of the most common and desirable safety features include a low oxygen sensor, overheat protection, automatic shutoff, and coo-to-touch. The cool-to-touch feature involves the use of special material on the surface of a heater. The special coat reduces the surface temperature of the heater. The low oxygen sensor ensures that there is sufficient oxygen for combustion. Overheat protection help to prevent accidents by automatically shutting off the heater when the temperature rises to dangerous levels.
  • Choosing the appropriate propane heater. Always use a propane heater that is appropriate for your space. Propane heaters usually include details about their heating capacity. The details show the size of the spaces that the heaters can be used to effectively heat.
  • Consistent maintenance. All propane heaters have detailed instructions on how they can be maintained and kept in excellent working conditions. Cleaning the heater is one of the primary methods of keeping a heater in excellent working condition. Always follow the instructions of the manufacturer when cleaning and maintaining your propane heater.
  • Following manufacturer’s instructions. To use the smallest propane heaters safely, always ensure that you follow the instructions provided by the manufacturer. Following the instructions strictly will eliminate the risk of accidents.
  • Do not leave the heater unattended. Some people tend to leave their heaters on throughout the night or when they leave their homes. However, standard safety practices demand that you switch off the heater when you leave the room even for a few hours. Similarly, never leave your heater on for the night. Following these recommendations helps to minimize the chances of accidents occurring when no one is near a propane heater.
  • Do not move your propane heater when it is on. Always ensure that your propane heater is off and cool before you attempt to move it. Moving a propane heater when it is still on or hot increases the chances of accidents. The heater may easily come into contact with highly combustible materials.
  • Keep the propane heater away from combustible materials. Ensure that your propane heater is positioned properly and away from fabric, paper, plastics, and other highly combustible materials. The temperatures on the surface of propane heaters tend to rise at times. Moreover, your heater can easily cause a fire if any of the combustible items at home get in touch with it.

If you’ll be using ventless heaters, you need to be aware of the dangers of ventless propane heaters to keep your home safe.

Wrap Up

Electric space heaters are excellent sources of heat for many homes, but the high electricity bills make them expensive, especially during the winter. If you don’t intend to use electricity, propane heaters are your go-to alternatives.

It’s important to realize that even the most efficient propane heater produces carbon monoxide as they burn, which is why you need an adequately ventilated room.

It would help if you also had your heaters regularly inspected by a professional. These kinds of inspections will look to ensure proper combustion and ventilation and to remove any obstructions from the chimney’s flue.
