A conservatory should be enjoyed all year-round, but naturally this can be difficult during the colder seasons. This is why you need to invest in a conservatory heater! It can be difficult to get a central heating system installed in your house, particularly if you have an older conservatory that isn’t as energy efficient as its modern day counterparts.

The same goes for DIY conservatories, as unless you install underfloor heating in the initial process – you’ll need a standalone heater to keep it warm in the colder months. It can be difficult to know where to start, especially in a smaller space where extra furniture can take up vital room. Overall, a conservatory heater is an essential so you can enjoy your conservatory all year round.

We review 8 of the best conservatory heaters available right now, taking into account their overall design, suitability and efficiency.

First, we have a very affordable oil filled radiator from Pro-Breeze. This comes with three adjustable heating output settings, 2500-watts, 1500-watts and 1000-watts so you can adjust the heating level to your own personal preference. It features an attractive 11 heating fins and is capable of heating rooms to the required temperature in minutes.

It benefits from safety features such as the tip-over automatic switch off and protection against overheating, so your conservatory, you and your family will always be safe. The 24-hour timer is a nice touch, allowing you to select the times when you need the heater on and when you don’t. There are wheels fitted to the base to make it easy to move from one room or area to another.

It comes pre-assembled and features a 1.5-metre power lead, which is more than enough for most conservatories and a clever little cable tidy.

Pro Breeze Mini Ceramic Fan Heater

1 / 2
2 / 2

Next in our list is another, though slightly smaller this time, heater from Pro Breeze. The notable thing about the Pro Breeze Mini Ceramic Fan Heater is the ceramic technology used in its design helps it to be more efficient and faster-operating than normal heaters. It offers two power settings, low and high, that provides 1200-watts and 2000-watts of power respectively.

For larger and wider conservatories, the 60-degrees auto-oscillation mode is great for ensuring you are always comfortable. You can, therefore, adjust the level of heat it provides by adjusting the power setting or using the onboard and easily adjusted thermostat.

To say this is lightweight and company is an understatement and while it does not feature wheels like the model above, it does have a carry handle that makes it easy to lift and move. Just as the Pro Breeze above though, it benefits from both the tip-over switch-off and overheat protection.

We have another accordion-like oil-filled radiator with 11 fins, this time designed and manufactured by NETTA. The NETTA Oil Filled Electric 2500-watt Heater has an adjustable thermostat and two power options, low and high. While low provides 1250-watts, high produces a luxuriously high 2500-watts. This means, despite its small and light design, it’s ideal for heating medium to larger sized conservatories.

We love that it’s easy to get the setting you require. With a 24-hour timer, you can set it to turn off and on when you are going to be using the conservatory most.

The cable tidy is a practical, neat and aesthetically pleasing solution to avoiding the inevitable tripping up over the 1.5-metres of cabling. While the wheels make it easy to transport from room to room. Even the older and more infirm will have not have very much trouble pushing it to the side when you need to hoover and clean around it.

Wärme Designer Electric Wall Heater

1 / 2
2 / 2

Now for something completely different, we bring the incredibly slick and slimline Wärme Designer Electric Wall Heater to your attention. This resembles a flat screen television more than a space heater but is a highly efficient way to warm up a space like a conservatory.

Much like a modern-day TV, you install this by mounting it to the wall. Amazingly it can heat areas up to 22-sq-metres and has an adjustable thermostat that offers between 15 and 33-degrees Celsius.

If you have a very modern-looking conservatory and are concerned a more traditional heater might look out of place, this is the product for you. It’s no wonder it was featured as a recommended item in the Architecture Art Design magazine and is used by house builders and developers across continental Europe. Easy to install, use and takes up none of the valuable floor space.

Duronic Convector Heater HV120

1 / 2
2 / 2

Perhaps you are looking to be free of the need for oil-filled radiators. The Duronic Convector Heater HV120 is a great conservatory heating solution that, thanks to its convector heating design, does not require oil. Although many of you reading this will have used oil-filled radiators in the past and swore by them, this can heat up much faster. With three selectable heat settings of 750-watts, 1250-watts and 2000-watts, there is a lot of flexibility.

On cooler days during the start and towards the end of the year, you could have it set to high, whereas when the warmer weather comes in, you can simply switch it down a level or two. To help reduce the times you need to fuss with the heat setting though, there’s also a built-in thermostat that means it can be set to never allow the temperature to drop.

At only 3.2kg, it’s lightweight and easy to move around. There are easy-grip handles on each side. Another thing that stands out about this model is that it comes with the slightly longer 1.8-metre cable.

Key Features:

3 different heat settings

Lightweight & portable

Wall mount or free stand available

Safety cut-off feature

6

De’Longhi Dragon 4 Oil Filled Radiator

1 / 2
2 / 2

From De’Longhi, a manufacturer we are sure you are all familiar with, comes the Dragon 4. The Dragon 4 Oil Filled Radiator is hardly a beast of an oil filled radiator to look at. With, however, three heat settings of 1100-watts (low), 1400-watts (medium) and 2500-Watts (high), it provides the kind of warmth that matches its powerful name.

A notable feature is the chimney effect it uses in the convection of air. Cold air is pushed through the hottest part and then up through the vents at the top. It heats rooms quicker and as it’s designed to warm a room of as much as 75-sq-metres, its output is more than enough for the average conservatory.

As you’d expect from a high-end model, it’s also equipped with a thermostat. With rubberised wheels at the base, it’s incredibly mobile and safe for use on just about any type of flooring. From a safety point of view, this model has anti-frost protection and an automatic cut-out switch to make sure it doesn’t overheat. With a mid-price tag, we think it’s a great investment.

Key Features:

3 different heat settings

24 hour mechanical timer

Easy transportation

Specification:

2 / 2

Yet another 11-fin oil-filled radiator from ANSIO comes this model with three power settings ranging from low at 1000-watts, through to medium at 1300-watts and 2300-watts at high. Although it is a lot like other conservatory heaters in our guide, especially to look at, there are some features that are unique to this model.

For one, it comes with a remote control. This means that you have full control over the adjustable thermostat, which can be set from 5- to 35-degrees Celsius, without having to go over to the unit.

Other features that make this model stand out a little from the others are the Eco Mode that can help to save power and make it more energy-efficient – perfect if you’re keenly aware of how much you are spending on your monthly electricity bills and trying to reduce them.

There’s also a Child Lock that disables all the controls so that little hands can’t get to it and potentially hurt themselves. Alongside these model-specific features, you also get a 24-timer and memory function that retains the most recently used settings.

Key Features:

3 different heat settings

1 / 2
2 / 2

We’re staying with ANSIO for another intriguing and innovative style that’s a little different from the other conservatory heaters we’ve featured. The Oscillating PTC Ceramic Tower Fan Heater is a slick and stylish design that can be placed in a horizontal or vertical position, depending on your preference and the available space in your lean-to.

When you consider that it has power settings of either 1200-watts or 2000-watts, it hardly matters that it only has two options compared to others with three.

Like the ANSIO model above, it also benefits from a remote control that enables you to adjust and alter the settings. As well as the other similarities such as Eco Mode and its memory that ‘saves’ the last settings used and the 24-hour timer that means it can be set to warm up and cut out when you are in the conservatory most and not at all.

A major difference with this model is that it has internal oscillation that helps to spread the air more easily.

Summary

There are clearly several great conservatory heaters on the market. Choosing the correct one can often be difficult, as you have to take into account a number of factors aside from your budget. For example, are you going to opt for an electric, gas or even tubular heater? Furthermore, you also need to consider your available budget, the power output and if it will heat up your size of conservatory; as well as considering how easy they are to use and whether they have safety features to prevent accidents, injuries and damage to your property.

Additionally, we also reviewed the best conservatory cushions and the most popular conservatory chairs that are on the market. Why not complete the look by checking out our guide on conservatory curtains. Once heated, a conservatory can be enjoyed all year round, so it may be an opportunity to use it as a dining room and fill it with conservatory dining furniture.

We’ve run through a few different things to consider before buying your conservatory heater – which may help you with your overall decision.

Type of heater

When looking at your budget, it’s important to consider whether an electric, gas or tubular heater would be best for you. Naturally, electric heaters are slightly more expensive – however if you don’t want to invest in a gas cylinder or simply don’t have space for one, then an electric heater would proabbly work best for you. Tubular heaters are usually the best for smaller spaces, too.

Size

The width and height of your conservatory heater is important to consider, as if you have a smaller space you will want one taller and skinnier instead. However, you may like the look of chunky heaters to pad out the aesthetic of your conservatory – so definitely check and have a look at what would work best for you.

Power

It can be easy to opt for the most powerful heater, but more often than not it may not be necessary. draught excluders, rugs and blankets can also help to keep you warm in the winter – so unless you have a gigantic conservatory, you may not need a heater with as much power as you originally anticipated.

Style

Does aesthetic matter when it comes to your conservatory heater? Absolutely! Make sure that you aren’t just picking a heater that works well, but one which will complement your conservatory and fit with the aesthetic that you want, especially as your heater will be a part of your winter furniture for at least a decade (probably more).

FAQ

What is the best conservatory heater?

Now, if we gave away that answer we’d be biased. However, the best conservatory is very subjective, depending on the conservatory and property size, as well as your budget. What we recommend is reading our reviews and making your opinion based on other reviews from those who have a similar requirements and expectations as you.

What is the difference between oil and an electric conservatory heater?

The difference is simple, one conservatory heater is powered by electricity, and the other will require oil. Both are effective, however you may have a particular preference.
