Paraffin Heater Buyer’s Guide

A paraffin heater is the primary choice for gardeners who need to keep their plants safe in the winter months. A paraffin heater allows you to grow plants year-round, even when the freezing temperatures hit.

Material

Paraffin heaters usually consist of a brass-plated wick burner and a metal base. You should look for a paraffin heater made from quality materials that are designed to last: if your heater gives up mid-way through a cold spell, your plants will suffer!

Most paraffin heaters are made from similar materials, so it comes down to finding the best one for your greenhouse.

Capacity

The capacity of your paraffin heater will directly impact its burn time. Those with a tank capacity of 4.5 L or more will have a burn time of a few days, while smaller tanks won’t burn for as long.

Output

The heat output is measured in watts, and most paraffin heaters will produce between 300 and 600 W of heat. Those with a higher heat output will be able to warm a larger space. By adjusting the circular wick of a paraffin heater you can alter the heat output and reduce the fuel consumption.

Paraffin Heaters FAQ

What is a paraffin heater and how does it work?

Paraffin heaters produce heat by burning the paraffin stored in the removable tank. They have a wick that draws paraffin from the tank to the combustion area.

The paraffin is ignited and lit, giving off a radiant heat that warms your greenhouse. Most paraffin heaters come with an automatic device that puts the wick out if the heater is knocked over.

How to use a paraffin greenhouse heater?

To start, you will need to assess how low to trim the wick to get the optimum amount of heat with the least amount of smoke. Once your wick is suitably trimmed, fill the tank with paraffin, light your heater, and leave it to do its job.

Remember to place your heater in an open and central spot in your greenhouse, away from water. Keep the window of your greenhouse open just a small amount to aid ventilation.

Conclusion

A paraffin heater is a cost effective and easy way to keep your greenhouse warm in the winter months, allowing you to grow plants and crops year-round. For its quality design, long burn time and ease of use, the Biogreen WM-P4 Warmax Power4 Paraffin Heater is our top recommendation.
