Here are the things to look out for so you can buy the right greenhouse heater for your needs.<\/p>    <h3 id=\"heat-output-and-coverage\" class=\"wp-block-heading\">Heat output and coverage<\/h3>    <p class=\"wp-block-paragraph\">The main factor to look out for is how powerful a heater is. More powerful heaters can raise an area\u2019s temperature by a fair bit, and they can also heat larger greenhouses with ease. While it\u2019s best to check how large of an area a heater can affect \u2013 usually in the description of a heater \u2013 looking at the heat output is not a bad way to determine if a heater will be good for your greenhouse.<\/p>    <p class=\"wp-block-paragraph\">Heat output is typically measured in British Thermal Units (BTUs). A larger BTU rating means more power.<\/p>    <p class=\"wp-block-paragraph\">Just make sure you\u2019re buying a heater with a heat output that matches your greenhouse\u2019s heating needs. More powerful heaters might not be able to go below a certain BTU rating, making your small greenhouse too hot.<\/p>    <h3 id=\"fuel-source\" class=\"wp-block-heading\">Fuel source<\/h3>    <p class=\"wp-block-paragraph\">Another major factor to consider is a heater\u2019s fuel source. There are many ways to power a greenhouse heater \u2013 wood, electricity, natural gas, propane, kerosene, and even solar panels \u2013 and each one has its pros and cons. Let\u2019s talk about electricity and gas as fuel sources, the only fuel sources we\u2019ve included in this list.<\/p>    <p class=\"wp-block-paragraph\"><strong>Electric heaters <\/strong>are cleaner, typically more precise, and sometimes cheaper to power compared to gas heaters. Electric heaters don\u2019t use up oxygen and don\u2019t produce carbon monoxide, which can be deadly in large amounts. However, they\u2019re largely corded; they need to be plugged in and will fail during a power outage.<\/p>    <p class=\"wp-block-paragraph\"><strong>Gas heaters <\/strong>run on either propane or natural gas. Natural gas is cheaper, but not as clean nor energy-efficient as propane. Propane is more environmentally friendly than natural gas.<\/p>    <h3 id=\"precise-temperature-control\" class=\"wp-block-heading\">Precise temperature control<\/h3>    <p class=\"wp-block-paragraph\">Since temperature is quite important for growing plants, you\u2019ll want a heater that you can fine-tune for the perfect greenhouse environment. Not all heaters have thermostats that can help you set the precise temperature your heater should heat your greenhouse to.<\/p>    <p class=\"wp-block-paragraph\">Some heaters don\u2019t even have more than two to three heat settings. If you don\u2019t have a thermometer in your greenhouse, you might want to invest in one if you choose a heater without precise temperature control.&nbsp;<\/p>    <h3 id=\"safety-features-and-certifications\" class=\"wp-block-heading\">Safety features and certifications<\/h3>    <p class=\"wp-block-paragraph\">Since they output heat \u2013 sometimes needing a flame \u2013 heaters have the potential to be quite dangerous. For the maximum safety, look for a heater with automatic shut-off systems. They can trigger when the heater is tipped, starts overheating, or when it detects low oxygen or high carbon monoxide levels.<\/p>    <p class=\"wp-block-paragraph\">Some heaters also come with certifications, such as the <a href=\"https:\/\/marks.ul.com\/about\/\" target=\"_blank\" rel=\"noreferrer noopener\">Underwriters Laboratories<\/a> (UL and cUL) mark, <a href=\"https:\/\/www.intertek.com\/marks\/etl\/\" target=\"_blank\" rel=\"noreferrer noopener\">Electrical Testing Laboratories<\/a> (ETL) mark, and the <a href=\"https:\/\/www.csagroup.org\/testing-certification\/marks-labels\/csa-marks-labels-north-america\/\" target=\"_blank\" rel=\"noreferrer noopener\">Canadian Standards Association<\/a> (CSA) mark. The UL, cUL, and ETL are marks that say an electrical device has passed standards, while CSA is used for other products \u2013 not just heaters.<\/p>    <h3 id=\"upfront-cost\" class=\"wp-block-heading\">Upfront cost<\/h3>    <p class=\"wp-block-paragraph\">Some heaters are quite expensive because of the extra bells and whistles that they come with. Others become more expensive because of renovations. You might need to renovate if you didn\u2019t <a href=\"https:\/\/lawnlove.com\/blog\/how-to-build-greenhouse\/\">build your greenhouse<\/a> to take temperature control into account.<\/p>    <p class=\"wp-block-paragraph\">Keep in mind that cost doesn\u2019t just mean the cost of the heater unit. There are long-term costs of running a heater, mainly fuel and maintenance. Some fuel sources, like electricity and natural gas, are cheaper than others; wood can be cheap as well if you end up with a lot of wood over the winter.<\/p>    <h3 id=\"cost-of-keeping-a-greenhouse-warm\" class=\"wp-block-heading\">Cost of keeping a greenhouse warm<\/h3>    <p class=\"wp-block-paragraph\">The greenhouse heaters on our list range from a little over <strong>$30 <\/strong>to more than <strong>$250<\/strong>, but that\u2019s only for the heater itself. Expect your heating costs to rise over time due to fuel and maintenance costs. You may even need to buy multiple heaters depending on the size of your greenhouse.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">However, that\u2019s not the only way to keep a greenhouse warm. Insulating your greenhouse or using construction materials with high R-values can help keep your greenhouse toasty throughout winter even without a heater. The cost of greenhouse insulation ranges from <strong>$1.50 <\/strong>to <strong>$4 per square foot<\/strong>.<\/p>    <p class=\"wp-block-paragraph\">Learn more about the cost of building and maintaining a greenhouse in our complete guide to <a href=\"https:\/\/lawnlove.com\/blog\/greenhouse-cost\/\">greenhouse costs<\/a>.&nbsp;<\/p>    <h2 id=\"faq-about-greenhouse-heaters\" class=\"wp-block-heading\">FAQ about greenhouse heaters<\/h2>    <h3 id=\"1-how-can-you-keep-your-greenhouse-warm-cheaply\" class=\"wp-block-heading\">1. How can you keep your greenhouse warm cheaply?<\/h3>    <p class=\"wp-block-paragraph\">Keeping your greenhouse warm doesn\u2019t have to be expensive. Some cheap ways to warm a greenhouse are <a href=\"https:\/\/lawnlove.com\/blog\/what-to-do-with-fall-leaves\/#5-use-them-as-insulation\">using fall leaves as insulation<\/a> and adding materials with high thermal mass. You can even make a tiny DIY heater. Learn more in our article about <a href=\"https:\/\/lawnlove.com\/blog\/how-to-heat-greenhouse\/\">how to heat a greenhouse<\/a>.<\/p>    <p class=\"wp-block-paragraph\">One of the best ways to keep greenhouse heating costs down is to insulate your greenhouse or use one of the insulated greenhouses from our list of the <a href=\"https:\/\/lawnlove.com\/blog\/best-greenhouse-kits\/\">best greenhouse kits<\/a>. That way, your greenhouse will experience less heat loss.<\/p>    <h3 id=\"2-how-many-btus-do-you-need-to-warm-your-greenhouse\" class=\"wp-block-heading\">2. How many BTUs do you need to warm your greenhouse?<\/h3>    <p class=\"wp-block-paragraph\">There are many ways to calculate how many BTUs you\u2019ll need to warm a greenhouse. One way is by multiplying your greenhouse\u2019s total square feet by its U-factor (dependent on materials) and then multiplying that value by heat loss (70 is the maximum amount of heat loss).<\/p>    <p class=\"wp-block-paragraph\">A much simpler formula is multiplying your greenhouse\u2019s area by 77. This will give you a rough estimate of how much BTU you will need to heat your greenhouse.<\/p>    <p class=\"wp-block-paragraph\">It might be better just to look at a heater\u2019s coverage area if you want to save yourself the headache of calculating BTUs.<\/p>    <h3 id=\"3-what-temperature-should-you-heat-your-greenhouse-to-in-winter\" class=\"wp-block-heading\">3. What temperature should you heat your greenhouse to in winter?<\/h3>    <p class=\"wp-block-paragraph\">You should warm your greenhouse to a minimum of 37\u00b0 Fahrenheit to support even the most tender plants. Ideally, your greenhouse should be 45\u00b0F to 50\u00b0F for your garden to thrive in the winter.<\/p>    <h2 id=\"let-pros-get-your-garden-ready-for-winter\" class=\"wp-block-heading\">Let pros get your garden ready for winter<\/h2>    <p class=\"wp-block-paragraph\">Heating isn\u2019t the only thing homeowners need to take care of to get their greenhouse gardens ready for the winter, and it\u2019s not like every homeowner can dedicate the time and energy toward their gardens this fall.
