A Summary of Advantages and Disadvanges

There are a number of advantages in using a paraffin greenhouse heater over other types of heating system available. Some of the notable advantages are :

  • When it comes to heating your greenhouse, paraffin heaters are cheap in comparison to other types of greenhouse heaters such as those powered by electric.
  • In addition to the cheap start up, paraffin is generally the cheaper option when it comes to the on-going costs.
  • Paraffin heaters give off a slight amount of carbon dioxide and so help with the growth of your plants.
  • They are stand alone units and you won’t have any trailing cables or gas pipe.
  • Due to them being stand alone, you have total freedom when it comes to their positioning within your greenhouse.

Sadly, as with everything, there are a number of disadvantages too.

  • Paraffin isn’t as popular these days as it once was and obtaining local supplies might be difficult. Fortunately, this is somewhat off-set by purchasing from the internet.
  • There is no temperature regulation. What this means is that once you switch the heater on, it remains on and keeps radiating heat whether it’s needed or not.
  • There is a small discharge of water vapour which, if not checked, can cause a breeding ground for mould and fungus in your greenhouse.
  • There is no fan to aid the air circulation in your greenhouse.
