Best electric heater for conservatory: 7 Great Options

Inside a conservatory watercolour


As the seasons change, the degrees Celsius can start to dip into lower than comfortable temperatures, especially at night. The conservatory tends to get the largest chill if it doesn’t have gas central heating or another form of forced hot air. Many conservatories have underfloor heating, but certainly not all. And although heat rises, heated floors don’t always do the trick when heating the entire conservatory. So, it might be time to find an alternative heat source. 

In this article, you will find conservatory heating options with 9 great suggestions to choose from to fit any budget, so if you are looking for heating ideas for conservatory, read on!

Types of Heaters

Before looking at heaters, it’s best to understand what kind of electric heater units there are on the market and what they offer. Buying the wrong heater could be a big and expensive mistake if you don’t know what to look for when purchasing the best conservatory heaters. Of course, there are other things to consider before buying the ideal electric heater of your dreams, but let’s first look at what kind of conservatory heaters there are out there for the taking before we get into what you need to consider before buying.

If your conservatory is properly insulated, you could utilise a smaller heater which would save you money on your utility bills. These recommendations assume your conservatory is not connected to your central heating system.


The first heater to mention is the fan heater. When most people think of fans, they think of cool breezes on a hot day. However, using a fan and oscillating mode when incorporating heat causes heat to travel farther into a room. It’s genius. The fan pushes the hot air around the room so it can reach every corner without leaving cold spots in the conservatory. 

Fan heaters can be on the noisier side of the heating a conservatory options since the fan needs to use a motor to push the air out without cooling it down. These electric heaters aren’t any worse than a regular fan regarding sound, but it’s not the quietest option on the list of electric heating.


Convection heating is how traditional radiators and electric radiators heat the room (despite their name). The heater draws in cool air from the bottom of the unit and warms it before releasing it back into the room as warm, cosy air.

The power of convection is to heat the air silently and continuously in the conservatory at an even pace, so the room is warm without cold spots.


A ceramic heater differs from convection heaters. Although, some convection heaters might have ceramic plates. A ceramic heater solely relies on a ceramic plate that heats up to extreme temperatures and heats the air around it before releasing the warm air into your conservatory. Ceramics can withstand enormous amounts of heat and remain hot for periods of time, making a ceramic heat option very eco-friendly and energy efficient.

Ceramic heaters are an excellent option for small and mid-sized conservatories. The larger rooms might not benefit as much from the ceramic plates since the heat will only travel so far before growing cold. The number one complaint when using a ceramic heater in a big room is feeling cold spots in far corners. Nevertheless, it’s a perfect option for mid-size areas, generating cosy heat.  


Radiant heat is one of the oldest heating methods since the open flame. However, thanks again to technology, radiant heat has been revamped, making it one of the best forms of heating today. Radiant heat uses fins, some units are filled explicitly with oil, to generate heat that can last long without dissipating quickly. 

Underfloor heating uses radiant heating to cover the floor evenly, so combining a radiant unit with underfloor heating will provide a rich warmth to any conservatory. In addition, radiant heat can travel to every room corner, making it an ideal option for a quiet and efficient way to heat your space. The only downside to radiant heat is that units can be hot to the touch, so it’s best to keep it away from little hands.

What To Consider Before You Buy A Heater

Before buying conservatory heaters, whether fan, convention, ceramic, or radiant, you need to consider specific things about your conservatory, like frequency, budget, and safety, before knowing which unit will work best for you and your family. In addition, not all conservatory heaters work the same in every space, so make sure you consider these few things when weighing the pros and cons of each unit and choosing the best heating system for your situation. 


Size matters when heating a conservatory. The unit doesn’t have to be bulky to kick off enough warm air to fill a large room, but knowing the size of your conservatory will help you narrow down the best options. If your conservatory is large, you must pick something that can provide accurate coverage to the area. Small or medium conservatories have plenty of options to fill the room with heated air. However, you wouldn’t want to pick something too strong that would make the area unbearably hot. 


Another thing to consider before clicking the ‘Buy It Now button on just any heating unit is to know how often you will be using the area that needs to be heated. Splurging on an expensive heating unit you don’t plan to use often can be a significant waste of money. On the other hand, investing in the proper portable unit might be exactly what you need for the room. For example, say you only use the room each night to read a couple of book chapters. Having a small, inexpensive portable unit could be the way to go. 


Efficiency is a big consideration in today’s world. Being eco-friendly and energy efficient is top of the list for many buyers. The price of the heating unit is one thing, but running it daily for hours on end can be shocking if it’s not energy efficient. Most good heaters have timers and automatic shut-off when the room reaches its ideal temperature. Saving money and the planet while keeping warm is a big win all around. 


Safety is another huge consideration before purchasing a heater for your conservatory. Think about the family when picking out a unit. Do you have little ones that could touch the surface? Do you have pets that could accidentally knock over the heater? Is the space small where a particular unit could damage the walls or furniture? These are all great questions to ask yourself before purchasing. Safety measures must be taken, and the best heater for conservatories has taken these concerns and implemented safety features for you and your family
