What I like most about this heater is that it has a seven-day programmable timer, so I can set it for my exact requirements. It also has an instant heat mode, which is ideal when you want to heat up your conservatory for a spontaneous relax. It can heat an area of up to 22 square metres. The heater has a built in sensor to prevent overheating and a waterproof casing, which means it would also be suitable for a greenhouse. It could also be used as an additional heat source in any room in the house or in sheds, garages or outbuildings.

The unit comes with a wall bracket and is easy to mount if you choose to do so. Once positioned on the wall you just plug it in and its ready to go. The front of the heater remains cool, so it is ideal if you have young children. There is also a lock on the settings, so little hands can’t interfere.

I have found this model very economical to run compared to other conservatory heaters, working out at about 7p per hour to keep my conservatory at 19 degrees through the cold weather.

Overall this is an effective, economical and stylish way to heat your conservatory, garden room – or anywhere else that needs a boost of heat in the winter months. It’s easily one of the best conservatory heaters for the UK market!

This Dimplex Cadiz Eco Electric Radiator has a powerful 2kw heat output and warms up a room fast. It has a choice of two heat settings with either one or both panels heating up depending on the setting you choose. It has a built-in thermostat which means it maintains your ideal temperature at all times. There is also a frost setting, perfect if you want to make sure your lovely conservatory plants don’t get killed off by the frost.

The heater also comes with a 24-hour programmable timer which is wonderful if you want to make sure a room is warmed up ready for when you get home out of the cold.

It is easy to move the unit around to use it in different areas as it comes on castors. It is very quiet when running and all you hear is the occasional click of the thermostat. It does have quite a bright light which might be annoying of you wanted to use it in a bedroom at night. However, this could easily be covered over.

While this conservatory heating isn’t the cheapest option to buy, it is more effective at heating up a large space than cheaper models. And it is more energy efficient than other conservatory heaters, meaning it may well save you money in the long run. It is also well made and will offer effective and efficient use.

Futura Electric Conservatory Panel Heater

This Futura Electric Conservatory Panel Heater provides an unobtrusive way to heat the conservatory or any other room, including the bathroom. It is a stylish flat white panel that would look good in any room in the house. It can be wall mounted or stand on the floor with the feet provided.

I like the fact that this conservatory heating is a splash proof heater, so I didn’t have to worry too much when watering the plants around it in my conservatory.

This model has three modes: heating mode, economy mode and frost-free mode. I found the heating mode effectively provided quite a lot of heat, enough for a bathroom or a small conservatory. The frost-free mode is handy for the conservatory if you want to make sure your plants survive the winter. This model also features a 24-hour, seven-day timer which is great if you want to make the most economical use of your heater. The built-in thermostat can be set between -5 and 50 °C.

Please note if this unit is to be installed in a bathroom it must be fitted by a qualified electrician.

This is a neat, stylish heater, ideal for the smaller conservatory. It’s by far one of the most stylish conservatory heaters available on the market.

Veito Free Standing Carbon Infrared Conservatory Heater

This Veito Carbon Infrared Conservatory Heater is really effective, heating up a conservatory in seconds and it really does get the room warm. It has two heat settings 600W and 1200W, but it does not have a thermostat, so you may have to turn it on and off at intervals to maintain the perfect temperature. The power switch is located at the bottom of the unit which is not particularly convenient.

It is not the most stylish option, in my opinion, however, if you want a lot of heat, fast, it could be the perfect choice for you. It is also small, easy to move around and simple to use.

This is the perfect choice if you just want your conservatory to be warmed up quickly when you are sitting out in it. I have also found that it doesn’t seem to dry out the air as much as some other heaters.

Pro Breeze Mini Ceramic Fan Heater

This Pro Breeze Mini Ceramic Fan Heater is extremely small but highly effective. It features ceramic heating discs that are apparently faster, safer and more energy efficient that traditional fan heaters. In addition, the product seems solid and well made.

I certainly found this conservatory heating to be very effective, heating up the space to a comfortable temperature in just a few minutes. It has two heat settings and also rotates meaning it can effectively heat up a larger space then you would expect from such a small unit providing an even temperature all round. It has a built-in thermostat and a safety cut out mechanism in the event that it is knocked over.

The unit is small and unobtrusive, you could easily put it on a table, or tuck it out of sight under one. It is good value for money as it seems well built and durable. I’m not sure it is as energy efficient as the panel heaters as it does have a fan and you can’t set it with a timer, however for occasionally use it would be a good choice.

This is a quiet and unobtrusive conservatory heater that is good value for money.

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.


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.
