Buying Guide for Greenhouse Heater

When it comes to selecting an add-on heating system for your greenhouse, there are definite features to consider. Herein are some valuable tips to help you with buying a suitable greenhouse heater.

Take note of these issues to get the value for every dollar spent without pointless expenses.


Type of Greenhouse Heaters

Familiar with the features you require to consider? If yes, let us now provide you a heads-up on the diverse heaters you would encounter:

Fan-Forced Heaters

As the name says, they have an internal fan plus a steel heating element. The component produces the heat, as well as the fan disperses this around.

Ceramic Space Heaters

Alike to fan heaters; however, the heating element is made of ceramic. Ceramic heaters are frequently much more effective and consume a negligible amount of electricity.

Infrared Heaters

There are no fans otherwise heating system elements inside these heaters. They use electromagnetic radioactivity from a bulb in its place. This bulb tends to be long-term, efficient, plus quick to heat up.


Geographical Place and Zone

The geographical site of your greenhouse specifies the local climatic pattern in a precise zone. It shows the time for which you need supplemental heating for your greenhouse crops.


The Size of the Greenhouse

When you start seeking greenhouse heaters, emphasize the size they are designed for. Greenhouse sizes could vary; therefore, a precise heater may not be appropriate for a different sized greenhouse.

The greenhouse heaters are accessible in numerous sizes depending upon the heating region; otherwise, the volume of air it could heat up. To get the faultless heater size, you need to measure the dimensions of your greenhouse. Just multiply the height from width to length of your glass room toward measuring the volume of air inside.


Essential Temperature for the Plants

The temperature you requisite to maintain depends on the plant type you intend to grow in the greenhouse. If you are growing seeds, set a higher temperature toward warming up the soil, plus speed up the germination procedure.


Type of Plants in The Greenhouse

Your choice of heater furthermore depends on the kind of plant you are growing in the greenhouse.

Some plants need more warmth than others; so, it is significant to compare the temperature settings of the heater with the temperature necessities of your plants.


Kind of Insulation Sheets

Before buying the heater, the kind of polycarbonate sheets or wraps used for insulation across the walls is another significant consideration.

Suppose you already have insulation sheets connected to the whole greenhouse. In that case, it is essential to determine the heat holding capacity of the material. Some superior insulation materials are accomplished of retaining heat for an extended period than others.


Weight & Material of the Greenhouse Heater

Horticulturists frequently commend mounting the greenhouse heater from the ceiling. It depends on the heating unit model you have bought. If it is too heavy or oversized, it can be risky and hard to mount the heater from the ceiling.


Position of Windows, Doors, and Vents

It is a factor of emphasis on selecting the most acceptable position to place the heater. It is always suggested to install the heater away from windows, doors, and vents to stop heat loss. The best electric greenhouse heaters will consume more electricity to maintain the essential temperature if it is located near the windows, doors, and ventilators.

The outlets, particularly the doors, are often opened for numerous purposes, including airing. If the heater is positioned near an opening, the heat will escape fast.


The Heating Efficiency

The heating capacity plays a vibrant role when purchasing a heater for the greenhouse. Watts is a thermal unit that is used to measure the heating capability of the heater. Preferably, the heaters come in an extensive range of 750W toward 3000W.

If you have a lesser space greenhouse of 400sq ft. or even less, it will be great to have a 1500W heater. It will be adequate to have for your greenhouse. If you have a large size greenhouse, then desire to have a heater with more heating capability.

British Thermal Unit, or BTU, is the amount for the heating efficiency. In brief, BTU determines how much energy the heater needs to increase the temperature of 1 pound of water by 1°F.

Based on the dimension for each product, you can recognize the amount of energy the unit needs to reach the labeled temperature. So, you could pick up the most energy-efficient heater yet still robust sufficient to warm up your greenhouse.


Safety Features

Safety comes first while we are going to purchase any electronic items, particularly heaters. A perfect greenhouse must-have safety features are similar to a thermostat controller, auto-shutoff function, and heat-resistant frame that confirms the users’ comprehensive safety while operating it.

Suppose somehow, the temperature surpasses, or any dangerous condition rises. In that case, these safety features confirm shutting off the heater plus electric heaters supply to evade these situations.

Thus, you need to check these safety features in the heater that provide safety to the operator.


Temperature Regulating Feature

The next significant thing to ponder is the thermostat adjusting feature. Preferably, the temperature setting tuning features to aid in adjusting the temperature according to the ecological state of the greenhouse.

Furthermore, this will help regulate the temperature of the greenhouse, plus if the temperature surpasses the setting, this would automatically shut off the heater. The thermo-regulation is vital to maintain the temperature inside the greenhouse according to your requirement.


Noise-free Operation

Numerous greenhouse heaters come with noise-free action features. This feature is valuable to have as it aids in avoiding the distressing operating sound of the heater fan. Ideally, there are numerous models of the greenhouse heater accessible that come with a noise-free running feature.

Thus, if you need a greenhouse heater to purchase, make sure to have this feature.


Compacted Size

The greenhouse heater must be compacted and portable sufficient to carry it anyplace fast in the greenhouse. Moreover, the small sized greenhouse heaters are easy to function as well. On the other side, the large heater is neither portable to carry nor might consume lots of space in the greenhouse.

So, be sure to have those heaters compacted and easy to transport in the greenhouse.


Air Ventilation Level

When heating the greenhouse, you require an appropriate ventilation system to avoid overheating the plants. The ventilation level moreover depends on the weather at the geographical location.

Generally, a small greenhouse has 1 vent at the side plus 2 on the roof. Automatic vents are the most suitable as they open and close as per the ambient temperature.


Area of The Plant Growing Zone

It can be determined by the number of plants you are growing. If you have fewer plants in a big room, you might keep a smaller compartment inside the greenhouse or generate partitions. Keep the plants together in place of spreading in the whole room. It requires less heat; thus, you can select the best heater for a small greenhouse to save cash on fuel or electricity.

Depending on the site of the growing zone, you can decide the position of your heater and install the arrangement for the power supply. 



The warranty plays a notable role in having a premium greenhouse heater. Typically, the greenhouses come with five otherwise fewer years’ guarantee period. It will aid you in keeping yourself free from replacement annoyances.


Heating Speed

There is no way to measure how fast the greenhouse heats. However, taking a look at how much power it offers could be a great idea.

The more power the heater gives, the quicker it would heat up. Furthermore, consider how BIG the heater is. Small ones would struggle to heat up fast.

Consider how cold the area you are placing the greenhouse is. Cold atmospheres tend to make heaters heat up lots slower (so you might need a faster-to-heat model).


Power Rating

This is just the measure of the heaters’ capability to heat up. You should use energy-efficient greenhouse heaters since they guarantee maximum power for energy consumed while operating the heater.

With each heater on the marketplace, they will have a power rating, plus it’s usually listed in kilowatts (kW). For the majority, they are likely to offer something between 1kW and 3kW; this is a massive difference for your greenhouse. If you have a small greenhouse, you will not need a tremendously powerful heater; however, it might be worth investing in one with diverse power settings in case you have strategies for a giant greenhouse in the future.



Price is the next consideration when purchasing a greenhouse heater. Before you start looking for heaters, choose a budget to make things easier for yourself.

The prices for greenhouse heaters could vary greatly depending on the size, power rating, and space it covers. Having a budget in mind would help you filter out pointless options from the list.

Be eager to set a price range beforehand you start looking; otherwise, you might get side-tracked by the costlier models. Depending on your necessities, a heater could cost below £50, or it might extend outside £120, so choose the most significant factors for you and stick to your decision.


Ease of use

Ease of use is probably an essential consideration and is fundamentally one of the most significant for less mobile users.

Paraffin and Propane heaters could be efficient and rapidly raise the temperature of your plants. This comes at the cost of more labor involved in refilling them and monitoring them carefully to stop a fire hazard.


Not all greenhouse heaters are similar. They vary in terms of features, heating capability, and other features. In our review, we have typically suggested models that feature an in-built thermostat plus a high-speed fan. These two features are significant to heat your greenhouse quicker and saving electricity.

When selecting, it is highly suggested to check with the purchaser about the area; the concerned heater keeps warm even below tremendously low temperatures.

We recommend measuring your greenhouse beforehand and comparing this to the airflow promised on numerous models to keep things simple. If the coverage is sufficient, you can be glad it will work inside the area you have accessible. Recall, insulation is a significant consideration since insulated greenhouses will not require powerful heaters.

Today, maximum of us have what the business considers ‘small’ greenhouses and most 2kW heaters permit for a competent job. If you genuinely aren’t definite which model to select, speak with specialists in the store, read reviews online, and talk to preceding customers (as well as friends and family!).
