Then the heated air is circulated thoughout the greenhouse with help from horizontal air flow fans or fan jets with poly convection tubes. Our heaters are highly efficient, easy to install, and cost-effective. Clients can trust our expert team to find the right size heater and correctly complete installation. With the right heating system, growers can help plants and crops stay healthy and produce year-round.

How To Choose the Right Greenhouse Heater

Choosing the best greenhouse heater is critical to your overall operations. Without a heater that can handle your space, you can potentially waste resources with the wrong setup. Here are key factors to consider when choosing a greenhouse heater:

Heat Capacity –

You’ll need to establish the ideal temperature for your greenhouse, which depends on the plants you grow and their natural environment. You’ll also need to account for the size of your greenhouse and the local climate. If you live in an area where the weather changes rapidly between seasons, account for this as well. Then, you can look for a large or small heater with the capacity to keep your space within a specific temperature range.

Safety Features –

 Many types of heaters include safety features that your team may value. For example, some heaters include an auto shutoff that turns it off if it gets too hot. Regarding gas heaters, some of these products will include an oxygen depletion sensor that detects low oxygen in the room. Consider safety features that your team may value when choosing a greenhouse heater.

Controlled Temperatures –

Traditionally, greenhouse heaters are equipped with manual temperature dials that need to be turned on and off by a person. However, most modern heaters have built-in thermostats and temperature controls to control this for you. This more advanced technology can help save you time that you would otherwise spend adjusting the heater. However, this control feature is ultimately a personal preference.

If you’re in your greenhouse every day and prefer to change and adjust the temperature yourself, this feature may not be important to you. Consider the type of temperature controls you want from a greenhouse heater.

When choosing a heater, you should consider other factors, like budget, space, and installation process. This will help you make a better choice for your facility and find a product you can keep for years to come. As always, you can count on Prospiant to be your resource for all things greenhouse design, engineering, and installation.


Use a greenhouse or space heater to keep your space warm in the winter. You can also create a thermal mass or heat sink to help keep it warm.

Depending on the type of crops you grow, and where your greenhouse is stationed, you may not need a greenhouse heater. Knowing what climate and soil your plants need to thrive can help determine if you need to heat the space.
