6 Best Conservatory Heaters for 2023 - Buying Guide (UK) (1)

Conservatories are not as well insulated as a house. Using an electric heater in an uninsulated housing will result in large heat losses and an increase in the electricity bill. That said, all the heaters I've included in my list below are as eco-friendly and efficient as they can be. Their goal is to save as much money as possiblewhile maintaining your conservatoryusable throughout the year.

Let's start with some important factors to consider beforehandbuy a heaterfor your winter garden.

Consider this before buying conservatory heaters


The size of the heater you need to heat the space should be your first concern. A small conservatory area obviously requires less heat to stay warm, so you can get by with a lower powered appliance such as a conservatoryinfrared heating. On the other hand, larger rooms require more powerful devices, such as freestanding gas heaters.


How will you use the heater? Let's say you need the occasional heat boost when you're entertaining guests in your conservatory during the winter. In this case, most models will suffice. Or maybe you want your conservatory to have a certain temperature at a certain time, for example a pleasant 21 degrees when you enjoy your morning coffee. In this case, a heater with a timer is practical.

Plants are often the main driving force for keeping the greenhouse warm during the winter months. To ensure that temperatures never drop below freezing, you need a heating system with frost protection.


Most of us worry about energy consumption, whether it's for environmental or financial reasons, and if you're no exception, opt for a thermostatic heater. It is much more energy efficient in the long term and offers a much more practical way of controlling the heat output.


HOTwall heatingif you have small children or pets. If you opt for underfloor heating, make sure it has an anti-tip device that will turn off the heating in the event of a tip over. All heaters in this list comply with current safety standards.

Fan, convection and ceramic heaters

Electric heatersThey generate heat in different ways, and the ones I'm showing you here are either fans or ceramic, convection or a combination of all three. They can quickly heat up your greenhouse, garage or rec room, but they come with their own advantages and disadvantages.

  • Kettle:Air heaters are a little noisy, but they only need a few seconds to fill the room with warm air. The air heater blows air from the heated element. In modern air heaters, this element is ceramic, which is why most newer models are sold as ceramic heaters. The ceramic heating element makes it safer andmore energy efficientthan conventional air heaters, because they quickly reach the maximum temperature. However, as soon as the heating is turned off, you must expect a sudden drop in temperature.
  • Convection boiler:Convection heaters are quiet and distribute heat evenly. They direct cooler air from the bottom of the unit through the heating element and out at the top. This process repeats continuously while the unit is on, always heating the cooler air drawn in from the ground.
  • oil cooler:The radiator fins are filled with oil (which should never be changed). This oil flows through an electric heater to reach the desired temperature. Since oil can stay hot for a long time, it is reasonable to assume that heat will radiate from the surface for some time. Due to their prolonged radiation, radiators are ideal for spaces that need to be continuously heated. This is another reason why oil heaters offer a more economical heating solution compared to conventional air heaters.

Dry air

Dry air can be a problem when using electric heaters, and the best way to combat this is with a humidifier. Humidifiers work by simply adding moisture to the air, resulting in less dry skin and fewer sinus problems. When used consistently, humidifiers greatly improve the dry environment created by electric heaters. The good news is that they are relatively inexpensive.
