Dr Infrared Heater DR-910M

Heavy-Duty and Portable

As with any type of appliance, greenhouse heaters can run into a bit of a conundrum when it comes to their design. Having a high-powered heavy-duty appliance is simply a necessity for many people, especially those with very large greenhouses, yet often with these devices, being heavy-duty means that they have to sacrifice portability. Having a portable heater that can be easily moved is also a necessity for many people, as they may need to try placing it in different areas of the greenhouse in order to find the optimal placement. Unfortunately, it seems nearly impossible to find a greenhouse heater that is both heavy-duty and portable.

The Dr Infrared Heater DR-910M Heavy-Duty Hardwired Shop Garage Heater is a great solution to this problem, as it retains both aspects of being heavy-duty as well as easily portable. Although the device is pretty heavy, thanks to the trolley with a handle and wheels, transporting the heater will not cause difficulties. You can easily roll it from one area to another in just a few moments, so changing its placement couldn't be easier. By the way, the wheels are made of rubberized plastic and do not leave marks on the floor coverings, so there also won't be any worries of the wheels scuffing up the floor.

This model has a total power capacity of 10,000 Watts and is designed for large non-residential premises such as greenhouses, garages, and warehouses with an area of up to 10,000 sq. ft. Turn it on, and the temperature will rise by several degrees in a few minutes. This heater is by far the highest-powered one that we review, as well as being one of the most high powered models available, so those who have a large greenhouse or other such areas will find this to be the ideal model for their needs.

The high power of this portable greenhouse heater also includes a number of features that help make this one of the best models on the market. As well as being a floor unit, this heater can also be mounted on a wall or ceiling, provided you purchase the proper mounting brackets separately. This gives the heater a certain level of flexibility in placement that many other greenhouse heaters can't match.

Fahrenheat FUH54

Efficient Technology

Most heaters of any kind, especially those powered by electricity, are hardly ever seen as being efficient. After all, it usually takes an extraordinary amount of electricity in order to generate the amount of heat that is required of any heater that is heating a large room, and thus it will inevitably have a large impact on your electric bill. Of course, there are other aspects of a heater that can take care with the usage of power in order to help tame the large electric bills that heaters tend to cause.

The Fahrenheat FUH54 Electric Garage Heater is a great multipurpose heater that can help being an element of efficiency to the heating process. Most heaters tend to rely on fans in order to help distribute heat, which in turn increases the amount of electricity used while the heater is running, as well as providing extra wear on the internal components. This model helps this thanks to an advanced sensor that starts the fan only when the heating element is hot - this eliminates the dispersion of cold air in the room and at the same time extends the life of the device. This also has the added benefit of reducing the total amount of electricity that the device uses while powered on, helping it be more energy efficient than many other models.

Review of Fahrenheat FUH54 Electric Garage Heater

Great for Tight Spaces

A problem that many people may encounter with a greenhouse heater is finding a place to put it. Most greenhouses are usually pretty constrained when it comes to floor space, which pretty much rules out floor units for such areas. Thankfully, this greenhouse heater was made for such situations, as it includes the ability to be mounted on either the wall or ceiling, whichever is of preference or necessity. The unit includes a built-in ceiling mounting bracket that lets you easily install it on the ceiling or wall, letting you orient the heater in such a way as to allow for the most efficient and optimal heat distribution throughout the room.

As for controlling the device, it includes a built-in adjustable thermostat that lets you adjust the temperature from 45º to 135º Fahrenheit, ensuring that the entire space is heated to the exact desired temperature. This unit also includes overheating protection that will automatically shut the unit off if it gets too hot, and reactivate it once it cools down to acceptable levels.

If you are looking for a productive heating device to maintain the desired temperature in the greenhouse, but the amount of available floor space is strictly limited, we recommend purchasing this model: it will definitely find a place due to the ceiling placement method and compact dimensions.

Bio Green PAL 2.0/US

Durable Greenhouse Heater

A characteristic that is necessary for any kind of greenhouse heater is its durability, especially when it comes to the specific climate of the greenhouse. An ideal greenhouse climate will often include high humidity, which is great for plants but can be devastating towards any electric devices. This means that many heaters that aren't rated for greenhouse environments simply aren't sufficient for withstanding the climate of a greenhouse, especially those that need high humidity for the plants inside.

The Bio Green PAL 2.0/US Electric Fan Heater for Greenhouses is a model that is made specifically to withstand the high humidity of a greenhouse environment. The case of this model is made of stainless steel and is resistant to corrosion, so the device can be operated in conditions of high humidity. And thanks to the IPx4 protection class, the heater can work even where condensation is possible. This makes it ideal for working well in any greenhouse environment, even those with a high level of humidity. In addition, the painted steel grills of the heater help keep out material that might cause interference with the heating elements of the heater, or which might ignite due to the high heat that is given off, making this device safe for your greenhouse.

Review of Bio Green PAL 2.0/US Electric Fan Heater for Greenhouses

Great for Smaller Greenhouses

This particular model is a lower powered option rated at 1500 Watts, making it ideal for a small greenhouse or a room up to 120 square feet in size. As such, this unit is much smaller than many of the higher powered devices, and thus more portable as well as easier to place in tighter spots. Although this is a floor unit, the heater sits on an adjustable stand that lets you orient and angle the heater in the optimal direction for distributing heat throughout the space, and the carry handle on top of the unit makes it easy to move from one place to another in order to find the ideal spot. One thing to be aware of, though, is that the outside case of the heater tends to get very hot when in use, so it is best to make sure it has cooled down before attempting to handle the unit.

If you need to organize high-quality heating of your greenhouse with minimal energy costs - we recommend purchasing this model. As well as its durability for a greenhouse environment, it is also suitable for use in residential premises, since the installed heating element practically does not dry the air.

All in all, this electric greenhouse heater will be a great addition to your greenhouse or other area that needs heating during the cold winter months.

Dr Infrared Heater DR218-1500W

Reliable Overheating Protection

What is one of the main points of advice for using a heater of any kind? Never leave it unattended. This is because heaters by their very nature pose a risk, thanks to the large amount of heat they produce as well as the danger of them overheating. While it may seem silly at first to think that a heater may overheat, this is a very real danger that they pose. Heaters produce a lot of heat, and overheating always runs the risk of catching either itself or something else on fire. However, it is not always practical to keep an eye on any heater while it is running, which can pose a problem.

The Dr Infrared Greenhouse Garage Workshop Infrared Heater is designed to allow it to be left safely unattended for short periods of time. The built-in overheating protection will automatically turn off the device in case of voltage drops and in case the permissible temperature of the thermostat is exceeded by at least a few degrees. This is an important point for continuous use in places where people are not always located, making it especially useful in a greenhouse, where most people just can't spend the majority of their time. With this model, leaving it unattended at least for short periods of time poses much less of a risk than with most other models.

Review of Dr Infrared Heater DR218-1500W Greenhouse Garage Workshop Infrared Heater

Universal Heater

This universal model from Dr. Heater will be indispensable for creating a comfortable environment in small unheated rooms with an area of up to 1500 sq. ft., with the power output of 1500 W providing a well heated environment for such a room. So, the heater will find a place not only in the greenhouse, but also in the workshop, in the garage, in the warehouse or even on outdoor patios and terraces. Basically, this heater can easily serve as a universal model, working well wherever you put it.

Not to say that this model doesn't excel as a greenhouse heater, though. This unit is a floor model and includes a floor stand that allows for completely stable placement. The small footprint of the heater also allows you to place it virtually anywhere, even in places where larger models simply wouldn't fit. The IPX4 structure gives it ample protection against water splashing and condensation, an important element when using it in an active greenhouse, and it is not susceptible to failure from excessive humidity. This unit does have a rather short power cable, so you will need to use an extension cord if it is not placed close to a power outlet. Outside of this, there are almost no issues that would prevent this floor model space heater from being the ideal device for your plants.

NewAir G56

Safe Floor Heater

As mentioned before, heaters can certainly pose a risk when left unattended. Outside of the reasons that were already mentioned, another risk they pose is in causing burns to anyone or anything that touches the heating elements inside of them. This is especially true of floor heaters, as any heater left on the floor is well within reach of children or pets, and in this case, the heater will require constant supervision while it is in use. This simply isn't practical in most cases, especially when the heater is being used in a greenhouse.

The NewAir G56 Garage Heater was built with protection in mind, letting it be used safely as a floor heater without the risk of causing injuries. The heating element is covered with a steel grill that provides ample protection against small fingers or paws from reaching inside, so the heater can be safely installed in places where there are small children or pets. Moreover, the case of the device maintains a comfortable temperature to eliminate the risk of burns, meaning that there is no risk of injury just by coming into contact with it. Moreover, the unit contains built-in overheating protection, and the rugged case and steel grill, in turn, protect the heater from external damage.

Review of NewAir G56 Garage Heater

Powerful and Affordable

One of the best aspects of this portable floor heater is its budget price, placing it well within most people's budgets. Despite the affordable price, though, this heater boasts an amazing amount of power, as much as 5600 W. Add to this the affordable mode with the air circulation function, and you can quickly heat a room with plants to the desired temperature. The heating capabilities of this unit make it ideal for rooms of up to 560 square feet, giving you plenty of flexibility in where you can use it.

Controlling this unit is quite simple. The adjustable thermostat dial is located on the front of the heater, allowing you to quickly and easily set the heater to the desired temperature. The power switch for the unit is located on the front as well, and contains a built-in light that shows when the unit is powered on, so you can easily see if it is on just with a quick glance.

A couple of small issues exist with this unit. For one, the fan is rather noisy when it is on, so you may want to keep this in mind if leaving it on for extended periods of time. Also, this unit uses a 6-30P plug and it requires being plugged into a 6-30R outlet, so this may limit the usability of the device in certain areas. However, these issues aside, this powerful yet very affordable greenhouse heater will work wonders keeping your plants healthy throughout the year.

Comparison of Greenhouse Heaters

What Is a Greenhouse Heater?

Those who are either very fond of growing and cultivating their own plants, or who grow and sell them for a living, will often use a greenhouse to grow them. A greenhouse is a structure that is usually made mostly with glass, which allows natural sunlight into the structure and trap the heat inside of it. This trapped heat helps to keep plants that typically require specific climate conditions growing well throughout the year, even during the autumn and winter months. Greenhouses are useful in virtually any climate, but are particularly important to use when growing plants that require a warmer climate in colder areas.

As good as greenhouses can often work, though, they sometimes simply can't protect the plants from extremely cold weather. The solution to this is to use a greenhouse heater during the coldest months in order to ensure that the temperature of the greenhouse remains in the range that is needed by the plants. Most greenhouse heaters work in a very similar manner to most convection heaters, in that they use electricity to generate heat. They work in conjunction with the natural abilities of the greenhouse to help keep the climate ideal for the plants.

While looking for a good greenhouse heater, you may also be interested in finding a good watering can for keeping your plants well-watered.

What Features to Compare

Most greenhouse heaters have some very similar characteristics, but they can have a great deal of variety in their capabilities, based on many of these same characteristics, as well as any extra features that are included with them. If you are not very well familiar with the best greenhouse heaters, then it would be quite helpful to be aware of these characteristics and features in order to ensure that you get the best greenhouse heater for your plants.

Type

The first thing to be aware of with any greenhouse heater is the type of heater, which indicates where it gets its source of power. The vast majority of greenhouse heaters (including all of the ones reviewed here) are powered by electricity, usually through a typical power plug. Electrical heaters ensure that you can keep the unit running without worrying about its source of power running out.

Power

The power of the greenhouse heater is just as important as anything else, as this indicates how much heat it can generate. The power of a heater will be measured in Watts, with the higher number indicating a more powerful heater. This is especially important for large greenhouses, which will often require as powerful of a heater as you can get.

Greenhouse Area

The greenhouse area that a heater is rated for indicates the maximum size of a greenhouse that the heater can adequately heat. Whichever greenhouse heater you choose, you will want to make sure that the total square feet of your greenhouse does not exceed the rating of the heater that you purchase.

Placement

Just as important as any other characteristic is the placement of a heater, which indicates where you can place it. Most greenhouse heaters tend to be floor units, with some offering extra support for installation on walls or ceilings. Wherever you want to place your greenhouse heater, make sure that the model you choose is appropriate for that area. There isn't much variation in capabilities between floor, wall, and ceiling units, so the placement of the unit is simply a matter of preference or needs for most people.

Control

Everybody needs to have some kind of control over their greenhouse heater, and knowing how it can be controlled is important for whichever model you choose. Most greenhouse heaters include an adjustable thermostat, although some models may also offer various other controls for additional functions, such as for ventilation.

Extras

Finally, it is important to know about any extras that are included with your greenhouse heater. Such extras can often include a variety of features, including ventilation, numerous fans for cooling or projecting heat, and overheating protection, among others. If there are any specific extra features that you want your greenhouse heater to have, you will want to make sure that you choose a model that includes them.

How to Setup a Greenhouse

Are you wanting to try your hand at creating and maintaining a greenhouse for your plants, yet you're not sure how exactly to go about it? Greenhouses have been around for thousands of years, and the art of setting up a good and effective greenhouse has been virtually perfected. It does take a lot of work, but it isn't difficult to do, providing you keep some simple things in mind while doing so. Read on for some great tips on setting up your first greenhouse.

Sunlight

The most important aspect of any greenhouse is in allowing in ample sunlight for whatever plants you are growing in it. The best way to do this is by using as much glass or other transparent materials as possible, which will allow the maximum amount of sunlight to enter. If you need a non-transparent roof for your greenhouse, though, then don't worry. As long as enough sunlight can enter from the walls, this should be fine.

Trees

If at all possible, set up your greenhouse near one or more trees. Doing so will provide several benefits throughout the year. Having constant uninterrupted exposure to sunlight can damage many types of plants, and having trees nearby can help provide shade during the summer. On the other hand, during the colder winter months where sunlight is more scarce, non-evergreen trees that lose their leaves will allow in as much sunlight as possible. This gives you a great natural way to provide protection for your plants.

Install Shades

If setting up your greenhouse near trees simply isn't possible, you may want to install shades in the greenhouse as well. These will help with protecting the plants from overexposure to the sun, while still allowing in enough sunlight. Furthermore, shades allow you to directly control the process instead of relying on nature for protection.

Ventilation

Any greenhouse is going to require proper ventilation in order to allow the plants to be healthy. Installing vents and a fan can help provide plenty of air circulation inside of the greenhouse, allowing your plants constant access to fresh air while preventing the greenhouse from getting too stuffy. Many plants grow stronger when exposed to some kind of airflow as well, so providing plenty of breeze for them goes a long way towards growing healthy and strong plants.

Heating

During the cold winter months, a greenhouse isn't going to be able to keep in as much heat from the sunlight as possible, especially those that use a lot of glass. This is because glass doesn't act as the best insulator. Having some kind of heater for the coldest time of the year will help prevent your plants from freezing.

Regular Maintenance

Once you have setup your greenhouse, the work is far from over. Keeping a healthy greenhouse will require constant maintenance throughout the year. Plants will require regular watering, dead leaves and branches will need to be pruned, and soil may need to be changed. Keeping the inside of the greenhouse clean and free of dirt and dust will help prevent insects from getting inside, as well as preventing the spread of diseases among the plants. Doing regular maintenance inside of your greenhouse will go a long way towards ensuring the total success and a long lifespan for your plants.
