3 Best Conservatory Heaters of 2026

Measuring only 18.5 x 15.5 x 26cm, this mini heater is ideal for small rooms. The Pro Breeze 2000W Ceramic Fan will sit perfectly under a desk, but could also be placed on a table top to spread heat at body height.

It’s a handy portable heater that’s really easy to move around thanks to its ergonomic carry handle. You can use it anywhere with an electrical socket nearby.

The Pro Breeze is actually the only convection fan heater on this list, and it effectively blows hot air around the room to keep the conservatory warm. It uses ceramic technology, with ceramic heating elements that make it more efficient than standard fan heaters.

This little heater has two power settings to make it more versatile and reduce energy consumption: 2000 W and 1200 W. You can choose between a powerful heat boost, or a steady flow of warmth. Unlike some fan heaters on the market, the Pro Breeze has no cool air setting, so it can’t double up as a fan on hot days.

There is an easy-to-use adjustable thermostat that helps switch off the heater when the room reaches the desired temperature. Plus, it has overheat protection to avoid it getting too hot, as well as an ‘anti tip over’ switch which will cause the unit to turn off if it gets knocked. The Pro Breeze has the potential to oscillate through 60°, but it can also be used on a static mode.

Compared to some of the more complicated electric heaters on the market, there’s no denying that the Pro Breeze has an easy-to-use, effective and simple design. However, it is therefore lacking some more advanced features. There’s no 24-hour timer, which could help this heater be more energy efficient, and no remote control either.

If modern design is your thing, and you’re in the market for a stylish and energy-efficient way to heat your conservatory, the Wärme Flat Screen Wall Mounted Conservatory Heater is a great option to consider.

This electric heater looks extremely stylish, with an ultra-slim design that resembles a flat screen TV at a first glance. It also has smart features and Wi-Fi accessibility which means it can be controlled via an app. This makes it possible to use either a phone or a tablet as a remote control.

Therefore, if you’re after a contemporary wall heater with simple smart features, this is one of the best conservatory heaters to consider.

This heater uses convection technology and has a programmable digital thermostat. It has a standard range of 15 – 35°C.

If you have kids or pets, you might well be concerned about their safety around a conservatory heater. However, this Wärme heater is wall mountable, so it’s kept well out of reach of little hands and wet noses. This feature really sets this heater apart from the others on this list.

It has a 2 kW output, which can comfortably heat a medium room of 22 m². You can set it to instant-heat mode when you need an immediate heat-boost on extra chilly days, or you can program a schedule on a daily cycle. Using these settings will help you to save energy and be more economical.

This heater has overheat protection and a waterproof casing. It’s therefore suitable for placement in the kitchen or bathroom as well as the conservatory.

Overall, the radiator measures 47 x 82cm and is super slim at only 8cm deep. As a result, it weighs a mere 9.3 kg and is therefore easy to move. The wall mounting features means it can be placed anywhere, and it comes with a wall bracket to facilitate this.

With an advanced system like this one, the set up process can be complicated. So, it might not be user-friendly for anyone who struggles with technology. There will also be some clunky noises when the device is cooling or switching on, which is quite normal for heaters.

In terms of adjustability, one of the best conservatory heaters is the Dimplex Cadiz Eco 3KW. It has two panels, one on each side, that you can switch on individually or at the same time.

Individually, the side panels produce 1.5 kW of heat. Together, they produce 3 kW. It’s therefore a very warming heater for winter, but has settings that also make it suitable for autumn and spring.

Another great feature is the electronic climate control system. This enables you to turn the heat up or down in one-degree increments from 5 – 35°C. Also, because this heater goes down to such a low temperature, it can also be used for frost protection without using lots of unnecessary power.

This convection heater produces 3 kW of heat and once you’ve figured out the right temperature for your home, you can set the memory and the heater will remember the settings for next time. Due to its high heat output, this heater is suitable for heating larger rooms.

It’s also programmable in other ways too. There’s a 24-hour timer which can be easily set using the backlit LCD display. This can help save energy, keeping heating bills down, as well as ensure the heater turns off at an appropriate time.

A remote control comes included, so the power settings can be adjusted from across the room, and the heater runs silently which is ideal for reading, watching TV or listening to music.

Dimplex claims that their heater is 10% more efficient than an oil-filled radiator and warms up 30% faster. Their heater is also very cost efficient at most temperatures. It gets less efficient when set over 25°C. However, usually you shouldn’t need to set the heater above 23°C, so this shouldn’t be a problem.

Whilst perhaps not as stylish as some of the other heaters, this is an easy-to-use option from a reputable brand. It’s also quite a portable heater, and can be easily moved around on its castor wheels.
