Conservatory Heater Buying Guide

Different Types Of Heaters Available

Choosing a conservatory heater is not easy because there are so many options. 

From size and wattage to heating principles and options, one has to look at countless details. 

Below, we’ve narrowed it down to the top 5 categories you’re likely to come across.

Electric Radiators

Electric radiators are simple appliances that you plug in and enjoy the warmth. They come in all shapes and sizes, so finding a style that will suit your conservatory shouldn’t be an issue. 

Moreover, because they transform into heat all the electrical energy from the outlet, they genuinely are energy-efficient and cost-effective, comparable to halogen heaters.

Convector Heaters

Convector heaters rely on a heating element, but they pull the air in, warm it up, then disperse it evenly into the room. 

They offer numerous heat settings and built-in advanced features. The latest models rely on forced convection, which makes it an even more attractive option.

Oil Filled Radiators

Oil radiators have fins filled with oil. They use electricity to heat the oil, and it may take some time until they reach full capacity. 

However, because oil retains heat very well, it will warm the room relatively fast and cool down slowly. 

While typically on the bulky and heavy side, they do come with a hard-to-ignore affordable price tag.

Panel Heater

A panel heater may rely purely on electricity or on convection to heat your conservatory. 

Compared to any other model, it will feature by far the sleekest and most elegant design. You’ll find panel heaters available either in the free-standing or the wall-mounting style.

Portable Fan Heaters

Portable fan heaters are just what their names suggest – heaters that rely on a fan to dissipate the heat. 

Meant as small, compact, and portable, most fan heaters on the market will heat up in a hot second. 

However, the built-in fan may raise some noise concerns for the more sensitive users.

Wall Mounted Vs Free Standing

Wall-mounted electric heaters for conservatories are not the norm because these rooms are made of lots of glass. 

However, with conservatories being attached to the house, there should be at least one solid wall where you can hang a heater and enjoy the set-it-and-forget-it functionality.

Free standing conservatory heaters are preferred for larger rooms where you don’t necessarily want to put more than one appliance. 

A free-standing unit will give you more flexibility in moving it around as you see fit at a certain point in time. 

If interested in this option, it should be lightweight, with castor wheels and a handle.


Size is by no means a way to classify conservatory heaters. You can get the full range, from something as small as 30 x 20 x 20 cm (at around 2 kg) to 50 x 20 x 60 cm (at a whopping 14 kg). 

Suffice to say that the style dictates the shape and often the size, but there’s no way to put all conservatory heaters in one box. 

There are just too many differences, size-wise.

Heat Settings

The rule of thumb is that the more flexible the heat settings, the more attractive the product. 

While the actual heat output settings go hand in hand with the power settings, there are some extras you should consider.

Specifically, a 2300W heater could also work at 1300W or 1000W, which means it has three heat settings. 

Most heaters and radiators will come with two such heat settings, garnishing their offer with other heat-related functions like tweaking a timer or a digital thermostat.

Energy Efficiency

For conservatories, electric heaters are the norm, and these heaters are, by definition, 100% efficient. 

They take all the energy from the power outlet and transfer it into heat, without losses. 

Depending on what they heat and how they dissipate the heat they produce, there are some differences.

Fan heaters are considered efficient and rapid, especially when heating a specific part of the conservatory, but they are noisy. 

The oil-filled heaters are more energy-efficient because oil is known to hold on to heat for very long. 

To make the most of your heater, energy-efficiency-wise, make sure you pick a model with a thermostat, so you have better control and make sure it turns off as soon as it has reached the desired temperature.

Power Settings

From as little as 400 watts to 2500, or even 3000 watts, the power settings that conservatory heaters provide are quite generous. 

Some of them have this one power option, which is also the maximum; others feature two to three options that you can choose from.

While it is best to have options, knowing how to use the power settings will directly impact the heater’s energy efficiency and your electricity bill. 

A low-power heater forced to work longer may be less effective than a high-power one used for a shorter period.


There are a few types of heaters, but their functions, features, and the way they are combined makes room for an overwhelming array of options. 

Safety features (overheating protection and automatic shut-off at tip-over) are must-haves, and it appears that an LCD display is also becoming quite common.

Other than that, you may benefit from a fancy open window recognition feature, child lock, but also anti-asthma/allergy running modes. 

However, if you have to pick, a digital thermostat and a timer are the most practical and desirable features.

Digital Thermostat

A digital thermostat makes the setup a breeze. It’s just simpler and much more intuitive to go through your heater’s options when you’re looking at a display than if you’d have only buttons. 

Moreover, a heater that can turn off when it reaches a particular temperature set by you and then turn back on as it notices that the temperature cools will make a world of difference in your comfort level.


The timer is yet another must-have functionality because it puts you in control and allows you to work on keeping the electricity bill lower. 

If you don’t need the conservatory heater to run continuously and only turn it on when you come home or first thing in the morning, the timer will be your best friend.

Our Verdict

You should be able to enjoy your conservatory all year round. Invest in a dedicated heater by taking the above recommendations into account.

Soon enough, the conservatory could become your go-to place in the house, even in the middle of the winter!

The best heater for conservatory should give you plenty of control options, prove energy-efficient, and beautifully blend in.

Don’t forget the safety features and try to pick a model with a generous warranty, just in case.

If you want to heat a focused area and do it fast, a fan heater will do the trick.

If you’re going to cosy up the entire conservatory and you don’t mind waiting for a little extra, then a convection or an oil heater is what you’re after.

Now that you know what to search for, take another look at the above top-rated products, and your favourite will stand out without a doubt!
