Wärme Designer Electric Conservatory Heater Review

If modern design is your thing, and you’re in the market for a stylish and energy-efficient way to hear you conservatory, take a look at this Warme flat screen wall mounted conservatory heater.

If you have kids or pets this is a great choice because it hangs on the wall, easily positioned out of reach of little fingers and wet noses. And let’s admit it – it looks amazing.

This conservatory heater uses convection technology and has a programmable digital thermostat. It has a range of 15 – 35 degrees Celsius.

What’s more, this is a smart heater and can be controlled via an app on your phone using a WiFi connection – how handy is that!

It has 2 Kw of output which Warme says can easily heat an area of 22 m². You can set it to instant-heat mode when you need an immediate heat-boost on those extra chilly days, and also program a timer which allows you to schedule a daily cycle.

There are built-in sensors to stop overheating and it has a waterproof casing – so, if you fancy one in the kitchen or bathroom too then go for it!

Overall the radiator measures 47 x 82 cm and is super slim at only 8 cm deep. As a result it weights a mere 9.3 kg and is easy to manoeuvre. It comes with a free wall bracket, but before you put it up make sure there’s an electrical socket within reach.

Duronic HV102 Electric Conservatory Heater Review

The Duronic HV102 Electric Conservatory Heater is another great option for your conservatory. Not only does it look really sleek and modern, but it does the job incredibly well.

Impressively, it can heat to full capacity in only one minute, so you won’t have to wait long to feel its warmth – very handy when you step into an ice-cold conservatory during winter!

Furthermore it’s got a useful built-in thermostat so you can have more control over the temperature. You can also use it either on its 2.5 kW power setting or 1.5 kW setting, depending on how intensely you want it to heat.

As a result, it’s really quite energy efficient, and easy to move around on its slick black wheels.

This heater is equipped to stop itself from overheating, and will also turn off if it is tipped over, so you can use it with confidence.

Pro Breeze® 2000W Mini Ceramic Conservatory Heater Review

The Pro-Breeze 2000W ceramic fan is a great mini-oscillating heater that warms your conservatory in no time. Its ceramic heating elements are way more efficient than standard fan heaters – no more waiting around looking at your frozen breath hanging in the air!

This little heater has two power settings, 2000 W and 1200 W, to make it even more energy-efficient. You can choose if you need a powerful heat boost, or a steady flow of warmth.

The easy-to-use adjustable thermostat also helps maintain a steady temperature. Plus, it has a safety feature which stops it from overheating, as well as an ‘anti-tip over’ switch, where the heater will turn off if knocked.

Measuring only 18.5 x 15.5 x 26 cm this compact conservatory heater is perfect for small spaces such as under the conservatory table or in front of your chilly toes.

It’s really easy to transport thanks to its ergonomic carry handle, and you can use it anywhere there’s an electrical socket – such as your garden shed.

This little guy is small but mighty – and a great price too!

Dimplex CDE3ECC 3KW Conservatory Radiator Review

Dimplex is an excellent heater brand and they don’t disappoint with the Dimplex CDE3ECC 3KW that’ll warm your conservatory in no time.

This traditionally-designed heater produces 3 kW of heat; it has twin heat panels on either side that provide plenty of warmth. Switch them both on for loads of heat or just one if you want to warm your toes.

Another great temperature feature is the electronic climate control system. This enables you to turn the heat up or down in one-degree steps from 5 – 35 degrees Celsius.

Once you’ve got the right temperature, set the memory and it’ll remember for next time.

The heater is programmable in other ways too. It has a 24-hour timer which can be set easily using the backlit LCD display. Set it to warm your conservatory as you walk the dog and then sit back and in toasty warmth on your return!

And, just to top it off, the Cadiz has a remote so you don’t even have to get out of your chair to turn it up or down!

Easily portable, Dimplex says this little heater is 10% more efficient than an oil-filled radiator and warms up 30% faster – just what you need on those frosty days.

Whilst perhaps not as stylish as some of the other heaters, this is an easy-to-use option from a reputable brand that will allow you to warm your conservatory just as you wish!

Things to Know Before Buying a Conservatory Heater

A conservatory is a wonderful place to relax in summer; bridging the gap between your home and the natural outdoor environment. A conservatory is especially wonderful when filled with exotic plants that just can’t survive a British winter outdoors.

However, in the winter months, your conservatory may get less use. It can become cold and bleak; a place to avoid. What a waste! What’s more, your wonderful plants may suffer and die as the temperature plummets.

Luckily, there’s a range of conservatory-heating solutions that can help you keep a relaxing, tropical-feeling space all year round. And, let’s face it, having somewhere to retreat to that is bright, warm and beautiful is even more important through the cold, grey days of a British winter.

So, keep your conservatory warm and inviting by investing in the best conservatory heater. This will allow you to enjoy your conservatory or garden room all year round!

The following tips will help you make an informed purchase:

Using a conservatory heater will help you get more use out of your conservatory in the colder months. You can transform the area from a cold zone where no-one goes, to another comfortable hang-out spot.

Heaters can also help keep the air warm in the conservatory, which may help keep any heat-loving plants you have in there happy.

Furthermore, these heaters are great to use any time you just feel like you need a little extra boost of heat alongside your central heating. The great thing about this style of heater is that you can buy one predominantly for use in your conservatory, but it will be portable enough for you to take anywhere in the house.

The majority of the conservatory heaters on this list can even be taken to be temporarily used in a shed or garage.

If you are looking for a heater that you will be able to move around as you wish, just make sure that it is not too large or heavy. The majority of heaters are designed to be portable, so you’ll probably find it has wheels anyway. But a heavy heater may put you off using it exactly as you’d hoped.

If you only have a small amount of floor space, you should check the dimensions of the heater to make sure that it will fit well. Alternatively, you could consider a wall-mounted option like the Warme flat screen wall mounted conservatory heater which won’t use any floor space at all!

A larger heater won’t necessarily do a more efficient job at heating your space, a combination  of size and power is important. As a general rule, a 2-kW convector heater will heat a room of around 20 m², whilst a 1.5-kW model will heat a room of around 15 m².

Most heaters will have an energy efficiency rating displayed in their description. Nowadays, it’s relatively easy to find heaters with excellent energy efficiency ratings, so don’t waste your time considering a model which isn’t up there with the best.

A thermostat is also a great way to improve energy efficiency. If you set the thermostat to a certain temperature, the heater won’t keep heating once it reaches it. Naturally, this saves energy as it doesn’t use more than necessary.

Similarly, if you buy a heater with a couple of power options you can avoid using more energy than you need. For example, the Duronic HV102 Electric Conservatory Heater lets you choose between a high and low power setting. Therefore, if you only want low-level heat, you have the option to do so instead of only being able to blast it on full power.

There are several different types of heaters which can be used in a conservatory. There are pros and cons to each type, so it will depend what you’re hoping to achieve.

Convector Heaters

These heaters work by warming the air in the room. As the air warms, it rises, and cooler air takes its place. As a result, the warm air is constantly moving around the room. These are generally a better option if you are looking to warm a room as they will heat the air. This type of heater often has a thermostat which can save you money as it avoids you overheating the room. Here are some different types of convector heaters:

  • Fan heaters work well and push hot air around the room. They may not be as energy efficient as other heaters because not all energy is put into creating heat; some is used on expelling air. Warm air can be easily lost through open doors and drafty cracks, so it’s important to keep the area air tight if you’re trying to use a fan heater to warm the room.
  • Oil heaters are slower to heat up than fan heaters, but offer steady convention heat. They will also stay warm for a while when switched off, meaning they continue to heat even when not using any power.
  • Electric convector heaters are generally all 100% energy efficient, because all of their energy is converted into a heat output. They can be relatively cheap to run and also include smart settings to give you more control over your heating.

Radiant Heaters

Radiant heaters don’t heat the air as convector heaters do, but focus on heating the objects directly in front of them instead. They don’t tend to evenly heat a room, instead focusing the heat on the area they are in. These heaters are perhaps better suited to being used for short periods of time, just to keep one person warm in a static position.

  • Halogen heaters, recognisable by their orange glow, will provide warm heat to objects directly in front of them. They are not very efficient at warming a room as a whole because they do not focus on heating the air.

Many conservatory heaters will have some safety features. The most common are overheat cut-out switches to stop them from overheating, and an anti-tip mechanism which means they will switch off if knocked over. That said, there are still some things to bear in mind when using a conservatory heater.

Don’t leave a conservatory heater on overnight – even if they have an automatic cut-off switch to avoid overheating, it’s still dangerous to leave them unattended for hours.

If you have young children or pets, consider a wall-mounted conservatory heater that can be installed safely out of harm’s way. This scenario is also a prime example of when an anti-tip mechanism is a great thing to have.

Conservatory Heater FAQs

This will depend on your usage. However, in general, the cheapest portable electric heaters are either oil filled radiators, oil- free panel radiators, or halogen/ infrared heaters. Bar fires and fan heaters tend to be more expensive to use in the long run.

Electric heaters are very safe as long as you follow certain precautions. If you have young children around you might want to choose a wall mounted panel heater. Alternatively, you could use a ceramic fan heater or an oil-free panel heater that is positioned out or of their reach.

Electric heaters often have a variety of safety features including anti-tip mechanisms which are activated if the unit is knocked over, and cut-out switches to avoid overheating. Always ensure you check the safety guidelines of the heater you choose; each will have different safety requirements.

Using a heater on a low ‘frost protection’ setting can help keep temperatures above freezing in a conservatory. That said, you should avoid leaving a heater unsupervised overnight. As well as using a heater, you can wrap your plants in fleecing and take them away from the window ledge – this is going to be the coldest spot in winter.
