Greenhouse Heater Buying Guide

You may find that during the colder autumn, winter and the earlier spring days you require some form of heat in your greenhouse. This guide will help you to determine which type of heater will best suit your needs. From a small heater that will work well in your propagation greenhouse to larger commercial-sized greenhouses, you’re sure to find what you’re looking for.

There are many things that you’ll want to consider regarding your greenhouse heater. You’ll want to consider how large or small your greenhouse is, what sort of energy you plan to use and how energy efficient the heater is that you’ve chosen, and you’ll want to know what the ratings are before you invest your hard-earned money into one of these heaters. We’ve compiled it all right here to make it easier than ever for you to find what you’re looking for.

Features To Look For In Your Greenhouse Heater

Not all greenhouse heaters are created equally so you’ll want to know all of the variables that may have an impact on the particular type of heater that you select for your greenhouse.

Before you embark on your journey to purchase a new greenhouse heater, you’ll want to consider the following:

The Size Of Your Greenhouse

Your greenhouse may be smaller or larger than others around you. You’ll want to select a heater that is designed for the square space of your greenhouse. Read the specs on the heaters that you’re considering and make sure that you’re purchasing a heater that will fulfil the needs and requirements for your particular greenhouse size.

Heater Type

Different Types of HeatersThere are many options here. You can select from electric heaters, fan heaters, halogen heaters, propane or even a paraffin heater. All of them will work to warm your greenhouse, however, each of them will run slightly differently. If you’re going to use a propane heater, for example, you’ll want to ensure that you have the proper type of ventilation so that no one is overcome with propane fumes.

If you don’t have power to your greenhouse, you certainly won’t want an electric heater out there. Be sure to consider all of your options before you make your final decision. You’ll also want to consider whether or not the heater that you’re considering has a fan with it to help propel the heat out to the outer areas of the greenhouse. A fan can help to disperse the heat in and around your greenhouse making for even heating and a more evenly dispersed heating to ensure optimal plant growth.

Power Rating

The power rating of your heater will help you to determine if it has enough power to generate the type and amount of heat that you will require for your specific sized greenhouse. Since each greenhouse is slightly different you’ll find that these vary greatly as well.

The power rating will determine the square footage of the heater unit’s ability to heat the greenhouse. Some will also be energy rated to give you the most power in comparison to the amount of energy that is used to heat your greenhouse. You’ll also want to consider a heater that will automatically shut itself off when the right temperature has been reached in the greenhouse. The heater should then turn itself back on accordingly when the temperature drops below the temperature threshold that you’ve set.

Cost

Before you begin on your quest to find the best greenhouse heater, you’ll want to have a budget in mind. Greenhouse heaters come in a wide array of budget-friendly solutions. Depending on what you’re looking for you’ll find that there is a vast difference in the overall cost of a greenhouse heater depending upon the size and the amount of power that it generates.

Set your budget before you begin and then do your research so that you can stay within your budget. This will help you to spend only what you can afford and not go over budget.

Sound

Different heaters are going to sound different so get a feel for what sorts of sound you’re willing to tolerate in your greenhouse. If you’re seeking a very quiet greenhouse you may not want to invest in the greenhouse heater that has a nosier motorised sound over a silent sounding version.

Fans and other features can also add sound to the particular type of heater that you’re looking at so be sure that you consider all of these factors and don’t be afraid to ask questions of the manufacturer or of other users. The more questions you ask, the more informed of a decision you can make in regards to which greenhouse heater you’re going to choose.

Conclusion

Depending on the particular plants that you’ll be growing in your greenhouse, you may need a more industrialised model as opposed to an everyday space heater type model. Consider what you’re growing and the purpose (personal or to sell) when you’re determining which type of heater to purchase for your greenhouse.

The more information you read and gather before you go shopping, the more armed you’ll be to make the best possible greenhouse heater purchase. You can purchase a heat lamp style heater, or a very large industrial-sized greenhouse heater depending on your needs and your budget.

Most people choose something that is middle of the road and focus on the specific features of size and convenience when they buy a greenhouse heater. If you’re planning a commercial-sized greenhouse operation, you’ll want to consider the best that money can buy to ensure that you’re going to be able to use it for the foreseeable future.

If you’re only concerned about a smaller more family-sized greenhouse you’ll be able to save a bundle and opt for something much smaller and more budget-friendly. Keeping your greenhouse warm in the winter months is easy when you buy the right size and type of greenhouse heater.

Guide to Heating Your Greenhouse During the Colder Months

When it comes to capturing and storing heat from the sun, greenhouses excel. However, when winter comes and sub zero temperatures become the norm, your plants will appreciate some additional assistance in this regard.

If you are looking to protect your warm weather plants from freezing temperatures during winter with the help of a greenhouse, use the expert tips listed below to make your structure as warm as necessary.

Start By Positioning Your Greenhouse Correctly

GreenhouseThe first step towards keeping your greenhouse as warm as possible during winter months involves proper positioning.

When putting up the greenhouse, make sure that it is in an east to west position, lengthwise, ensuring that one of the longer sides is facing southwards; thus being directly exposed to the sun. The northern facing side should preferably run along a wall or fence. This helps shield this side from direct winds thus providing some much needed insulation.

Use Insulation

You can further protect your plants from sub zero winter temperatures by properly insulating the structure.

To minimise the loss of heat, clip bubble wrap along the inside of the structure. Alternatively, you can use sheet foam insulation to get the highest level of insulation during the night if you have a plastic greenhouse. Moisture proof insulation should be used to insulate the northern facing wall in glass greenhouses.

Take Advantage Of Compost

Providing your plants with the right nutrition is essential, if they are to get through the winter season unscathed. Using an organic fertiliser is highly recommended.

However, did you know that you can provide the necessary level of nutrition and keep the green house warmer for your plants by simply string your compost within the structure, preferably in a central location? Well now you do. Storing the compost in the structure also protects it from any loss of nutrients that may be occasioned by exposure to rainfall.

Build Thermal Mass

Any object that is capable of absorbing heat during the day and giving it off during the night, when temperatures dip, is referred to as thermal mass.

You can create thermal mass in your greenhouse by following a few simple tricks. The easiest way involves using black coloured capped containers filled with water that is also black in colour – using black food dye – . This maximises the heat absorption capabilities of the water.

The containers should then be distributed all over the structure, in direct exposure to sunlight.

Get A Heating System Designed Greenhouses

If you still need to raise the internal temperature of your greenhouse, consider getting a heater that is specifically designed for this purpose. From fuel and paraffin oil to electric powered systems, the market is full of affordable and effective options.

When shopping for the perfect heater, remember to match it to the requirements of your plants; you can save a lot by avoiding units that are too powerful for the intended purpose.

Once you get the heater, position it in a way that directs airflow where it is needed; the most vulnerable plants.

With these tips in mind and practice, keeping your greenhouse and the plants therein, sufficiently warm during freeing winter weather will be much easier.
