Mr. Heater 30,000 BTU Vent Free Blue Flame Natural Gas Heater MHVFB30NGT

Check Price on Amazon

Pros:

  • Much cheaper than a propane based model
  • Works well in sudden weather changes
  • Remote control/Thermostat
  • Great for large rooms, outdoors, and garages
  • Flame guard
  • Relatively easy to install
  • Comes with 10-foot hose

Cons:

  • Burning fumes aren’t good for the environment
  • The noise is pretty loud
  • Some people may not like the look/color

This is an obvious alternative to propane based space heaters, mainly because it’s much cheaper to run. The vent free design means it uses a higher BTU rate.

Plus, it comes with a 10 foot hose that allows for some extra freedom of movement.

Which type of space heater is cheapest to run?

The largest factor in how much a space heater costs to run in a year is the type of space heater you choose. The three main types of space heaters are convective heaters, radiant heaters, and ceramic heaters.

Convective heaters, which are also known as forced-air heaters, are the cheapest to run. They blow air across a heat source and that air heats up and hits you, making you warmer. In the winter, this type of heater will make you really warm. But in the summer it won’t feel nearly as warm. Some of these types of heaters can cost you a lot to run. For example, a number of models are available that use oil as a fuel source. Thermostats are often used to make sure that the air in the room reaches a desired temperature. These heaters are generally inexpensive and offer a very consistent heat.

Which heating method is more efficient for a room?

Although both methods are considered to be “efficient,” they have advantages and disadvantages over the other.

Radiant Heater Advantages:

~These types of heaters are typically cheaper to operate than air conditioners.

~You don’t have to wait several minutes to start feeling heat from these types of heaters. They deliver instantaneous warmth.

~Can heat a room evenly over a larger area.

~The temperature is easily controlled by adjusting the amount of air that circulates through the grids.

Radiant Heater Disadvantages:
