A greenhouse heater is an essential item if you intend to grow flowers and plants. Greenhouses are naturally warm places as the glass absorbs the sunlight, but a heater can make a huge difference, especially during our unpredictable British winters when temperatures can plummet. If you need to invest in this equipment, we have created a list of the best greenhouse heater and nine other high-quality products.
Regardless of the size of your greenhouse, a reliable heating system is important to protect your plants and produce. If there is minimal sunlight or a particularly cold day, you can use a greenhouse heater to boost the temperatures and protect from things like frost. In this guide, we feature a selection of electrical, paraffin, and propane heaters that would be perfect for your greenhouse.
The Bio Green Warmax Power5 paraffin heater is our pick for the best greenhouse heater. It has a simple build and has a relatively small footprint so it can easily fit on the floor of your greenhouse. It also has a large capacity paraffin tank so you can keep it operating for days without having to refill the tank. If you want a robust solution and powerful heat output options, this is an excellent choice.
This paraffin heater has two chimneys and a large capacity fuel tank. The fuel tank has a single opening, and you can easily use a nozzle to put the paraffin in.
Both of the heater chimneys have dials on to alter the flow of heat and paraffin. Also, on the base, there are two fixtures that you can use to screw it to the floor.
This paraffin heater is our best choice, but it still could have a few minor issues. For example, it requires some degree of assembly and you could find this difficult even with the instructions. Also, over time, the exterior casing could eventually start flaking.
The Bio Green Palma Heater could be the best greenhouse heater with thermostat. Aside from having a digital thermostat, this floor palma heater features a 2KW power output. Although it has a decent power rating, it is still small and compact. It can also be easily moved due to the carry handle and its ergonomic circular chassis.
Measuring 28 x 195 x 315mm, the Bio Green Palma is a compact greenhouse heater. It is floor-standing, and it is also IPX4-rated for protection against dust and splashes.
If you opt for the Palma heater with digital thermostat, then don’t be intimidated by the extra tech as it is still relatively easy to operate. It has a simple swivel dial, and you can turn it from minimum to maximum to alter the temperature. At its maximum setting, it generates a 2000W output.
This Palma heater is a well-rounded product but it could present a few issues. For example, you could find that the 2KW output is not enough to keep a larger greenhouse warm. Also, there are two versions of this heater available – one with, and one without a thermostat so be sure to choose the one with when adding it to checkout.
The CrazyGadget Large Paraffin super warm heater is one of the best paraffin heaters available. It has a single heating chimney and a large fuel tank that also serves as the base. This means you can easily place it anywhere on your greenhouse floor, or on your greenhouse shelves next to your plant setup. Due to its design, this is our pick for the best single burner greenhouse heater too.
This heater has a single chimney that is connected to an underside fuel tank. The fuel tank has a single opening so you can easily refill it with more paraffin. There is also a control dial so you can alter the flow of paraffin.
The fuel tank of this heater has a capacity of 5L which, when full, should last for up to 80 hours. The heating output should provide heat for a greenhouse up to 6ft x 6ft.
It also features a robust design and is made from durable materials. The chimney, for example, is threaded, and comes with brass-plated components.
This paraffin heater is a great option, but it does require assembly. This is fine, but in some instances, the instructions have been left out and, if included, they may not be the clearest. Also, over time, the outer casing of the paraffin tank may eventually rust.
The Elixir Gardens TH03 is our choice for the best tube heater. If you want a simple heating element that is easy to use and install, this is a great choice. It has a 135W heating element and connects directly to a mains socket. For energy consumption, this is a good option, and it should help keep your electricity bill to a minimum.
You can buy two versions of this greenhouse heater – a 70cm / 90W version, or a larger and more powerful 100cm / 135W version. Both have the same design features and fixtures for installation.
This greenhouse heater works great as a low-energy heating solution. Also, it is easy to assemble, and the wall brackets supplied are easy to fit too. It can be installed in many different ways, but the ideal stance is vertical.
Each tube is also IPX4 waterproof from all angles, so don’t worry about stray water dripping from your plants as you water them.
This Elixir Gardens heater also has a thermostat control which is a simple dial located below the power switch. The power switch is also isolated and has safety coverings surrounding it.
Although this tube heater is a solid product, it could have a few problems. For example, it has an electrical power cable and this could not be long enough depending on your greenhouse setup. Also, it is supposed to provide a constant heat level of 90-degrees, but it may not manage this constantly over a prolonged period.
If you want a simple paraffin heater for frost protection, the Srendi Fireside Small Paraffin Anti-Frost heater is one of the best options. It can work in any season, but it is effective at keeping your greenhouse frost-free due to its powerful paraffin heating system. This could be a suitable heater for multiple size greenhouses and you could easily install several paraffin heaters in a larger area.
This Srendi heater has a decent-sized fuel tank and is easy to operate. The fuel tank has a maximum capacity of 1.7L, and this could last for up to 10 days.
The top grill and safety cover can also easily be removed. You simply twist the top plate and it should disconnect from the main fuel tank.
It is also easy to operate, you simply light the heating area and it will run automatically providing you have a fuel supply. It is made completely from metal so always take care when handling this heater.
This paraffin greenhouse heater is a good choice, but you could experience a few issues. For example, it doesn’t have a thermostat. The grill that extrudes the heat is small, and you could find that a layer of soot builds upon it. Also, at higher temperatures, you could also find that the paraffin heater emits a thin layer of black smoke.
The Lighthouse 2kW electric greenhouse heater is a great product and is highly portable due to its encased design and carry handle. It is one of the best greenhouse heaters that offer precision thermostat controls and a high heating rating. These electric heaters will keep your greenhouse frost-free, but they also provide great air circulation.
The Lighthouse heater is one solid unit and has a carry handle in the top. It has a front grill that allows the heat to travel through and the grill is spacious to allow a decent airflow. There is also a large control panel that has two dials on – one for the power, and one for the heat, making this heater relatively easy to sue.
On full power, this electric greenhouse heater should heat an area in your greenhouse equivalent to 20m2. The air output is also 186 m/3. Once powered, the fan has continuous operation and requires a mains power supply. The overall dimensions of this heater are 230 x 198 x 320mm, and it is lightweight so you can easily carry it as well.
This 2kw greenhouse heater is a great option, but it may not be perfect. Firstly, once powered it provides constant air circulation. This means that it may not have a high level of energy efficiency. Also, due to the constant usage, it could reduce the overall life of the electric fan heater.
The Dimplex ECOT1FT Tubular is a fantastic choice if you’re looking for a heater with digital thermostat for use in smaller greenhouses. It has a standard tubular design and is also easy to use with minimal controls. Despite the small heating element, this heater still has a decent power output and could be great for frost protection during the unpredictable UK winter months.
This heater is a great option for smaller greenhouses. It has a digital thermostat so you can change the output easily. It also has a simple on/off switch and connects to mains power via a standard electrical cable and 3-pin UK plug.
We also like that this heater has some added safety features. For example, it has an auto-reset thermal overload cut-out. This means that the heater should never overload and burnout due to an electrical surge.
All of the parts of the heater are water and dustproof to IPX4 standard including the 1.5m electrical cable and the plug. The digital thermostat also has a frost watch function, and there are 6 potential outputs for different greenhouse settings.
This simple tubular heater is a great option, but it could have a few downsides. Based on an electric greenhouse heaters review, the tubular heater may not have enough power for your whole greenhouse – you may need multiple units. Also, it is thermostatically controlled, but you could find that the temperature accuracy is temperamental.
The Tooltime 2ft Portable Electric Tubular greenhouse heater is another great option that is brilliant for heat circulation and a consistent heat supply for any season. It has a traditional splash-proof design and is easy to use with a simple thermostat to change the heating temperature.
The Tooltime 2ft portable greenhouse heater provides an even heat distribution across the whole heat element. As it is a tube heater, it also has a relatively low consumption compared to some other models on this list.
The casing of the element is made from white enamel, and the whole heater is splash-proof to a rating of IP55. This means it should be safe from any condensation and water spillage. It is also CE certified.
For usage and installation, it has a 1.3m cable and is connected to a standard British 3-pin plug. It also comes with all the necessary fittings including wall brackets. You can use these to mount on the floor, shelves, or any solid surface.
This tube heater is a solid choice but it could have a few minor drawbacks. For example, it only has a 1.3m electrical cable. Depending on the setup of your greenhouse, this could mean that you need to use an extension unit. Also, some customers have found that the tube heater does not come with the fittings as stated.
If you are looking for portable propane gas greenhouse heaters with a portable and propane design, then this model is our best pick. It has a relatively large stainless steel chassis and provides excellent heat and air circulation. The 1.9kW output is also thermostatically controlled, and it has a simple ignition system too. If you prefer a propane heating solution, this is the best option available for medium to large size greenhouses.
This propane heater has a great green steel casing which provides extra protection, but also blends in with your greenhouse setting.
Included in the basic package you get a 1m hose, 2 clips, and a propane regulator. These accessories ensure you can easily fill the propane tank of the heater.
It offers a 1.9kW output, and the ignition system is also easy to use. This heater output should be suitable for a greenhouse of 8ft x 6ft in size. For operation, it has six different settings, and it uses a relatively low level of propane gas for its larger size.
This propane gas heater could have a few drawbacks despite its good performance. Firstly, there is no carry handle. This means you have to physically lift the heater to move it around your greenhouse which could result in injury. Also, this easy-to-use heater has a stated usage rate of propane, but you could find that this differs depending on the brand and strain you use.
The Voche Electric 90W Tubular greenhouse heater is one of the best greenhouse heaters due to its small design. It is splash-proof and IPX4 rated which means it won’t get damaged by any condensation or build-up of moisture. If you are happy to use electric heaters and prefer mains power over paraffin or propane, this is a good option.
The Voche tubular heater with wall brackets which can be mounted to either the floor, walls, or shelves.
The overall length is 750mm, and it has a wattage of 90W. This translates to an output of between 220-240V and it can be thermostatically controlled for temperatures between 0-90 degree celsius. It also has a useful LED indicator so you can see when it has power.
For power, the Voche greenhouse heater has a 1m electric cable, and come with a standard 3-pin UK plug. The enamel materials and heating element are also splash-proof to IPX4 standards.
Although this Voche product is one of the best tube heaters available, it could have a few problems. Firstly, it has a 1m electrical cable. Depending on your greenhouse setup, this may not be adequate and you may need an extension. Also, this tube heater provides a centralized heat source, therefore you may need several to heat a larger greenhouse.
We have given you the best greenhouse heaters available in the UK, but how do you choose a suitable model for your situation? It can be tricky and we understand this. To help, we have created a short buying guide below so you can easily choose.
Before buying a heater for a conservatory or greenhouse, we first advise assessing your greenhouse. You should have a clear idea of what you are working with, and also how to heat a greenhouse properly. Ask yourself the following questions – how big is the greenhouse? What available floor space is there? What (if any) power outlets do you have inside? What type of plants do you have inside? (Different plants may require different temperatures).
By understanding the above, you can look at the below considerations to choose the best greenhouse heater for your circumstance.
Firstly, there are two main types of greenhouse heater – fuel, or electrical. Fuel heaters typically use either paraffin or propane which is ignited and burned to heat up the required space. This requires no electricity which is a plus.
Alternatively, electrical heaters require mains connections. There are two types of electric greenhouse heater – tube heaters with a heating element, or an electric fan heater which circulates the air. Both of these electric greenhouse heaters require no fuel.
Tube electric heaters generally require less electricity, whilst a greenhouse fan heater will require more power as they have more powerful motors. You must consider this and look at which option would be the most efficient when looking to heat your greenhouse.
You should also consider the heating area. Depending on the power of the greenhouse heater, it will only heat a certain area of your greenhouse. In some instances, depending on the size of your greenhouse, you may therefore need to buy more than one.
Paraffin or electrical greenhouse heaters offer the greatest output and can heat a larger area. In most instances, you will only need one of these to heat your greenhouse. Alternatively, smaller electric heaters have a smaller heating element and thus can only cover a smaller area. You may need a whole setup of tubular heaters, for example.
The size and weight of the greenhouse heater are important. This depends on how much space you have in your greenhouse. Some greenhouse heaters are larger and require placing on the floor. Others, like tube heaters, can be fixed to the wall or to greenhouse shelves and require less space.
Different greenhouse heaters have different fixtures and installation methods. For example, paraffin heaters, usually require no fixtures and are generally free-standing with legs or a solid base. Alternatively, tubular heaters generally have two brackets so you can screw them to walls or shelves. Some paraffin heaters may need assembly, but they should generally be easier to set up than fixing a tube heater.
Don’t let your hard work and toil in the greenhouse go to waste! Make sure you have an adequate heating system so that you can keep your beloved plants and produce healthy and warm. You can achieve this with any of the above ten best greenhouse heaters.
However, our choice for the best greenhouse heater is the Bio Green Warmax Power5 paraffin heater. This greenhouse heater is a versatile product that offers an excellent heat supply via its large paraffin fuel tank and dual chimney design. It is also a great energy-saving option as it requires no mains power, and can result in up to a 40% improved burning time.
