Is an external electric heater more expensive than a gas heater?


If you have outdoor living space, you can try to extend it for as many months of the year as possible. In winter this task becomes impossible without installing some kind of heating system to fight the cold and wind. In the heating industry there are several options for your deck, screened porch or veranda. The two most popular options are electric and gas heaters. However, which one is more economical and better suited to your Maryland porch?

Whether a gas or electric heater will be more economical for you depends largely on the market you live on. This is because gas and electricity prices vary from region to region and are not static in each country.

Do the calculations

The easiest way to determine the best financial choice for your heaters is to make these quick calculations.

For example, let's say electric heaters - like those from Infratech - need about 4 kilowatts per hour to work. If the electricity in your region costs $0.10 per kilowatt hour, then we know it costs $0.40 per hour to run one heater. This is achieved by multiplying the cost of electricity by the amount of energy needed to run it.

The same calculation can be made for gas. If your gas burner operates at 34,000 British Thermal Units (BTU) per hour, you need to multiply this by the price per BTU to determine your cost per hour of gas heater operation.

Is gas or electricity more expensive, and why?

While the price difference between electricity and gas depends on location and market, gas heaters are generally more expensive than electric heaters. This is partly due to the loss of performance of gas heaters. Combustion plays a role in gas heaters, and as a result, energy is lost. Gas heaters have an efficiency of about 75%, while external electric heaters work with an efficiency of 90%.

Other factors to consider for a room on deck or a room with a screen

When making the calculations, one should not forget to take into account also other factors that may affect overall operating costs. This includes how many of each type of radiator you want to install.

If the prices are to some extent comparable between gas and electricity, as is often the case, choose the type of radiator that works best on the outside. This can be based on any number of factors, from the aesthetics of the radiator to the requirements of the outdoor location to control the options.

When operating costs are separated by a thin price margin, make sure you do your research and choose the radiator that will offer the best versatility and functionality and make your deck, veranda or porch the most comfortable in the cold months.
