If you wish that you could comfortably use your conservatory all year round, then you might be on the hunt for the best heater for conservatory rooms and extensions.

A conservatory can be a wonderful addition to a family home. These spaces not only give you more room to spread out in your house, but they also provide an excellent opportunity to enjoy the views of the great outdoors and soak up the sunlight in summer. However, it’s fair to say that conservatories aren’t always as comfortable in the winter as they are during the summer months. When the temperatures drop, it’s easy for a conservatory to lose its appeal – particularly if you don’t have a source of reliable heating available.

While conservatory heating takes care of itself in the summer months, thanks to the glass soaking up the heat of the sun, it’s not so easy to stay cosy in winter. The good news is that the right conservatory wall heaters and portable radiators could ensure that you can make the most out of this room in all seasons. To help you choose the perfect heating solution, we’ve scoured through countless conservatory heater reviews to bring you our top choices.

Best Heater for Conservatory Reviews – Top 10 Picks

1. De’Longhi Dragon 4 (Editor’s Choice)


If you’re looking for the best way to heat a conservatory in winter, you’ll be drawn to technologies that are similar to the ones you use to keep the rest of your home warm and toasty. In this case, then you’re sure to appreciate this oil-filled heater from De’Longhi.

Featuring 2 KW of heat output and three heating settings to choose from, it delivers a blast of hot air into any small space, including your conservatory.

There’s a thermostat included to reduce the amount of time you waste on over-heating your rooms, and an anti-frost device in case you want to leave the machine in your conservatory throughout the winter and the temperatures drop to below zero. This heater even looks the part, with a sleek white finish that should fit well into any room. There’s also a mechanical timer included for when you want to set your heater going according to your schedule.

According to De’Longhi, Dragon 4 is excellent at heating the air in any room of your home much faster than the most traditional oil-filled radiator. The unique design of this machine means that you can get the perfect combination of convection and radiant heat in one package. The only major issue that most reviewers had with this radiator was the fact that it has an annoying clicking sound when it’s heating up or cooling down. This might not be a big problem during the day, but the clicking can keep you awake at night.



  • Excellent design for accelerate heating
  • 3 heating settings to choose from
  • Pre-assembled with wheels and carry handle for portability
  • Thermostat and anti-frost device included
  • Powerful performance


  • Annoying clicking sound keeps you up at night
  • Slight plastic smell after use

2. Pro Breeze 2000W Mini Ceramic (Best Small)

Pro Breeze 2000W Mini Ceramic

If you’ve got a tight budget to work with, you may be looking for a less expensive way to heat a conservatory without compromising on performance or heating results. This exceptional miniature fan heater from Pro Breeze is an excellent choice if you’re looking for a highly robust piece of technology.

The advanced ceramic heating elements in the system provide heating that’s more efficient and faster than standard heaters.

There are two power settings to choose from depending on the level of heat that you need. What’s more, you can set your adjustable thermostat to ensure that the heater stops producing heat after it reaches your ideal temperature. The ability to adjust the thermostat to your ideal temperature will help to cut down your heating bills.

One of the great things about this Pro Breeze heater is the fact that it’s small and lightweight enough to carry around your entire home. There’s even a carry handle to help you out. Importantly, it is built with an overheat and tip-over protection switch that automatically turns off the heater during unsafe conditions. Just keep in mind that it’s better for small spaces than larger rooms. You won’t get the same heat output you’d get from a full radiator, but it’s definitely enough to chase the chill away. Additionally, some of the conservatory heater reviews we read complained of annoying ticking noise.
