More Detailed Conservatory Heater Reviews

Dimplex CDE3ECC 3KW Conservatory Radiator

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 little heater produces 3kw of directional heat as it has twin heat panels on either side. 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 five degrees all the way up to 35. 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 with two program period settings on a backlit LCD display with large buttons. Set it to warm your conservatory as you walk the dog and then sit back and bask in toasty warmth!

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 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. It’s a well thought out conservatory heater that hits all the right notes.

Dyson AM09 Hot + Cool Fan Heater

Dyson says their Hot and Cool AM09 fan heater is a product for all seasons – it heats your conservatory in the winter and cools it in the summer. Yes, it is pricey but it’ll last a lifetime.

There are no blades or heating elements on show making it safe for children and pets. Instead, this piece of tech uses ‘air multiplier’ technology to draw in the air and release it warm or cool.

Hot air can be focused on one spot with jet air projection or used to warm the whole room efficiently.

The jet function is directional and compared to others it easily crosses the length of a large conservatory. You can set the temperature from 0 degrees to 37 with the remote control that magnetically sticks to the heater when you’re not using it

This heater tilts on its own centre of gravity and won’t topple over, but just in case there’s an automatic safety cut off.

What I love about this Dyson heater is that it’s simple to clean. There’s no more trying to fit a duster in the grills, failing miserably and then dealing with that horrid burning dust smell.

Wärme Designer Electric Conservatory Heater

If modern design is your thing and the Dyson AM09 is too pricey take a look at this Warme flat screen wall mounted conservatory heater. It’s a stylish and energy-efficient way to heat your conservatory.

If you have kids or pets this is a great choice because it hangs on the wall away from little fingers and wet noses. And let’s admit it – it looks amazing.

This convector design conservatory heater has a programmable digital thermostat and a range of 15-35 degrees.

It has 2KW of output which Warme says can heat a 22 square metre area easily. There’s an instant heat mode for those extra chilly days and a timer for a daily cycle.

There are built-in sensors to stop overheating and it’s built-in waterproof casing so if you fancy one in the kitchen or bathroom too then go right ahead!

Overall the radiator measures 47 cm x 82 and is only 8cms deep. It comes with a free wall bracket, but before you put it up make sure there’s an electrical socket within reach.

Pro Breeze® 2000W Mini Ceramic Conservatory Heater

Pro-Breeze 2000W ceramic fan is a cracking mini oscillating heater that warms your conservatory in no time thanks to its ceramic heating elements that are way more efficient than standard fan heaters. No more waiting around looking at your frozen dragon breath!

This little heater has two power settings of 2000W and 1200W to make it even more energy-efficient, and an easy-to-use adjustable thermostat to maintain a steady temperature. It has overheat protection and an ‘anti-tip over’ switch for safety.

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

It’s perfectly portable with a 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 DXFF20TSN Fan Heater

The lowest cost of my recommendations, but still powerful enough to warm your conservatory, is the Dimplex DXFF20TSN Fan Heater.

This flat designed 2kw blow fan has a thermostat with several settings (including frost protection) operated by simple-to-use turn switches located on the top of the heater.

The heater switches off when it reaches the temperature you’ve selected which is a great safety feature and efficient use of electricity.

It also has cool blow settings for the hotter months, a neon mains indicator, and a thermal overheat safety cut-out.

If you need a low-cost blow heater to quickly and safely heat up a conservatory, spare room, or gym this is a great buy. It’s portable with an integral carry handle, super simple to use, and a bargain price.

Conservatory Heater Buying Guide

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

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

Luckily, there 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 warm and beautiful to retreat to is even more important through the cold, grey days of a British winter.

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

When choosing a heater, consider the size of unit you will need to heat the space you have. A very large conservatory will, of course, take more heating than a small space.

Consider how you will use your heater. If you just need an occasional boost of heat to allow you to use your conservatory in winter than any type of unit will do. However, if you need the room to be kept at a certain temperature at certain times, then choose one with a timer. If you have delicate plants, you should choose a model with a frost-free setting to make sure the temperature never goes below zero.

In general, a unit with a thermostat is more convenient and energy efficient if the unit is to be used for long periods.

If you have young children or pets, consider a wall mounted option that can be installed safely out of harm’s way. Alternatively, ensure your heater does not get too hot to the touch and has an anti-tip mechanism or safety cut out switch.

FAQs

What is the cheapest type of electric conservatory heater to run?

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

Is it safe to use portable heaters around children and pets?

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. Alternatively, you could use a ceramic fan heater or oil free panel that is positioned out or of their reach. Electric heaters have a variety of safety mechanisms including anti tip mechanisms, cut out switches to avoid overheating and cut out switches that are activated if the unit is tipped over.  Always ensure you check the safety guidelines of the heater you choose as each will have different safety requirements.
