The 6 Best Conservatory Heaters (Reviews) and How to Pick Yours

Your conservatory can be a great source of pleasure during the summer months. When it’s warm outside, it can function as an extra living area, a greenhouse, and a lovely sunroom. But what about all the cold months when you are not able to use it? Getting efficient conservatory heaters can extend their use well into the dead of winter.

Conservatories are not insulated anywhere near as good as a house. Using an electric heater in an uninsulated enclosure entails a great degree of heat-loss and an increase in your electric bill. That said, all the heaters I’ve included in my list below are as eco-friendly and efficient as they come. They are meant to save you as much money as possible while keeping your conservatory useable all year.

Let’s start with a few vital factors you must consider before buying a heater for your conservatory.

Consider This Before Purchasing Conservatory Heaters


The size of the heater you will need to warm your space should be your first concern. A small conservatory floor area obviously requires less heat to stay warm so that you can get away with a unit with lower watt output, such as an infrared heater. Conversely, larger spaces call for more powerful devices, like freestanding gas-fired heaters.


How will you use the heater? Suppose you need an occasional boost of heat when entertaining in your conservatory during winter. In that case, most models will do the job. Or, perhaps you want your conservatory to be kept at a specific temperature at specific times, e.g. a comfortable 21 degrees while enjoying your morning coffee. In this case, a heater featuring a timer will come in handy.

Plants are often the main drive to keep a conservatory warm during winter months. To ensure that the temperatures never drop below zero, you will need a heating unit with frost protection.


Most of us worry about energy consumption, be it for environmental or financial reasons, and if you are no exception, choose a heater with a thermostat. It’s way more energy-efficient in the long run, and offer a much more convenient means of controlling the heat output.


A wall-mounted heater is safely bracketed out of the way if you have small children or pets. If you choose a floor-standing heater, make sure it has the tilt-over safety feature to shut the heater off should it be knocked over. All heaters in this listing are up to the current safety standards.

Fan, Convection and Ceramic Heaters

Electric heaters generate heat in different ways, and the ones I will show you here are either fan, ceramic, convection or a mix of all three. They can heat your conservatory, garage, or hobby room quickly, but also have their pros and cons.

  • Fan heaters: Fan heaters are a bit noisy, but take mere seconds to fill up a room with hot air. A fan heater blows air from a heated element. In modern fan heaters, this element is ceramic, which is why most newer models are promoted as ceramic heaters. The ceramic heating element makes them safer and more energy-efficient than traditional fan heaters as they quickly reach the peak temperature. But, as soon as the heater is turned off, you should expect the temperature to drop rapidly.
  • Convection/Convector heaters: Convection heaters are silent and disperse heat evenly. They channel colder air from the bottom of the unit, through the heating element, and out the top. This process repeats continuously while the unit is turned on, always heating the colder air sucked in at the bottom.
  • Oil Radiators: The radiator’s fins are filled with oil (which never has to be replaced). This oil flows through an electric heating element to reach the desired temperature. Because oil can stay hot for a long time, you can expect the heat to radiate from the surface for a while. The extended radiation is what makes radiators ideal for rooms that require heating over a continuous period. This is also why oil radiators offer a more economical heating solution compared to standard fan heaters.

Dry Air

Dry air can become a problem when using electric heaters, and the best way to combat that is with a humidifier. Humidifiers work by simply releasing moisture into the air, resulting in less dry skin and fewer sinus issues. If operated consistently, humidifiers will drastically improve dry environments created by electric heaters. The good news, too, is that they are relatively cheap.
