Paraffin heaters are one of the most popular methods of heating greenhouses. Even the best insulated greenhouse may require an extra heat source when housing heat loving plants such as peppers. Plants that require a moderate amount of heat such as garlic or chives can benefit immensely from some additional warmth for optimal yield.

Plants housed in greenhouses in colder growing zones may require extra warmth to survive the fall and winter months. Paraffin heaters are safe, efficient and affordable. Proper greenhouse ventilation and regular heater maintenance will ensure proper paraffin heater performance.

The most popular form of paraffin heater is a compact un-vented device with a small tank and a wick. Many greenhouse users large or small are very fond of these heaters because they are portable.

Units will run on paraffin fuel so o not require an electrical outlet to function. This can be important if it is difficult and expensive to get a electrical cable out to the greenhouse if its at the far end of a long garden.

It is vitally important to keep the paraffin heater’s wick trimmed to prevent the flame from burning unevenly. It is also very important to refuel the paraffin heater outside of the greenhouse in an open space to prevent accidental combustion, Paraffin heaters are relatively low maintenance, but they do require regular observation. Checking the state the heater’s wick during routine refueling should prevent any potential safety concerns.

Most modern paraffin heaters have several built in safety mechanisms, including an anti-tip switch that will turn the heater off if it is knocked over. Paraffin heaters are ideal for both small and large greenhouses. A larger greenhouse may require several heaters. Paraffin heaters are a solid choice for spaces that require multiple heaters because they are cost effective and relatively easy to maintain.

An additional greenhouse heat source is an important tool during times of the year when plants that thrive on direct sunlight are not able to get their fill. When considering a heat source, moisture and fume output can greatly impact the health of the surrounding plants. Most well maintained modern paraffin heaters burn fairly clean. There is a chance that a small amount of carbon monoxide may escape from the heater.

Nutrient rich plants generally won’t be impacted by a slight change in carbon monoxide levels. These heaters can give off a small amount of moisture, which may impact humidity sensitive plants. Closely monitoring moisture sensitive plants for changes and adjusting the orientation of a paraffin heater will generally solve any humidity related issues.

Paraffin heaters have evolved over time into one of the most reliable sources of providing additional heat to greenhouses. Relying on a heater that employs an open flame can be daunting. Greenhouse operators across the globe have successfully used paraffin heaters without incident for decades.

Modern paraffin heaters feature numerous controls which are designed to promote safety and efficiency. This type of heater has enabled countless heat loving plants to survive otherwise inhospitable conditions. Most greenhouse enthusiasts will speak highly of the versatility and affordability of paraffin heaters. All seasoned gardeners know that maintaining a stable temperature is one of the most important variables when attempting to produce robust plants.
