How The DIY Works Team Tests & Rates Heaters For Your Conservatory

Conservatories are prone to the cold due to the lack of insulation and many of the rental properties we manage feature them. Therefore, over the years we’ve dealt with the cold by testing out a variety of oil-filled and electric heaters.

In terms of our ongoing testing, we analyse the heater’s ability to heat multiple-sized conservatories as well as how easy they were to operate.

We particularly liked the latest range of “smart” heaters with their digital displays and how they integrated with WiFi to control them. However, as this isn’t what everyone requires, we also tested budget heaters too.

To keep up our commitment to reviewing and testing the latest heaters that are ideal for conservatories, we are continually testing out the latest options available from top brands in the UK. This means that we are regularly upgrading the heaters in our conservatories when we notice that brands have released a new model.

As well as our testing and experience of using a range of heaters, we also based our recommendations on the latest research and a number of factors. Some of the factors that we took into consideration included the heater’s performance, design, ease of operation, safety features, additional functionality, warranty and value.

1. Best Wall Mounted: Wärme Designer Electric Wall Heater

(How We Review →)

The Wärme Designer is a stylish and energy-efficient heater that’s ideal for mounting to any wall of a conservatory. It’s a simple plug-in and easy to use heater that requires zero maintenance or servicing and that’s why it’s so popular.

In terms of the installation, included in the box are all the fixtures and fittings to mount it onto the wall. However, it’s important to note that it’ll require 30 cm of clearance at the top and bottom as well as a nearby power socket.

  • 2,000W heat output
  • Digital thermostat
  • Instant heat mode
  • Built-in safety sensors for protection
  • Waterproof casing
  • Easy to install and zero maintenance
  • Supplied with all the fixture and fittings
  • From our testing, we found that setting or scheduling timers wasn't that straightforward

To conclude, the Wärme Designer is a highly efficient and modern wall heater that’ll make a great addition to any conservatory. The brand also state that the heater doesn’t require any servicing or maintenance, which is another big bonus that makes it a worthwhile investment.

2. Best Free Standing: Dimplex FuturRad Portable Eco Radiator

(How We Review →)

Dimplex is a brand that offers a wide range of portable heaters and the FuturRad is their new and improved freestanding model. It’s also one of the most powerful electric heaters within our roundup with an output of 3,000 watts.

Therefore, due to the impressive heating performance that it offers, it’s best suited for mid to large conservatories (18-25m²) that need an extra boost during the cold winter months.

  • Can be remotely controlled using the brand's smartphone application
  • Offers impressive heating performance
  • Easy to setup and use
  • Backed by a 10 year guarantee
  • Long 1.8 metre power cable
  • Most expensive heater within our roundup

To conclude, the Dimplex FuturRad is the best freestanding electric heater for cold conservatories. The impressive performance along with the new and improved design means that it really does tick all the boxes. The only main drawback is its premium price tag but it’s a worthwhile investment that certainly won’t disappoint.

3. Best Aluminium: MYLEK Aluminium Electric Panel Heater

(How We Review →)

The MYLEK electric panel heater is another popular option that can be mounted to the wall or remain freestanding. A unique feature of this particular model is that it’s constructed of aluminium, which is a superconductor of heat and makes this heater far more efficient than the cheaper alternatives on the market.

In terms of the heat outputs offered by the brand, the heater is available as a 600, 900, 1200 or 1500-watt model.

  • Highly efficient aluminium design
  • Remote control and programmable LCD display
  • Three heat modes including frost protection
  • Displays the current room temperature
  • Child lock functionality
  • Flexible installation
  • Relatively expensive when compared to the alternatives

The aluminium construction and excellent efficiency of the MYLEK electric panel heater are the standout features. It’s a high-performing option to consider that allows for flexibility in terms of the installation and it certainly won’t disappoint.

4. Best All-Rounder: FUTURA Eco Electric Panel Electric Heater

(How We Review →)

The FUTURA Eco is a more affordable alternative compared to the Wärme alternative above. It’s usable as a wall-mounted or floor-standing heater and the brand offers it as a 600, 1000, 1200, 1500, 1800 or 2000-watt model.

A unique feature that’s perfect for conservatories is the “Auto Open Window Detection” functionality. The purpose of this function is to automatically switch off the heater if the room temperature has a sudden drop of 5 degrees or more.

  • Choice of six different heat outputs
  • Flexible installation
  • Advanced thermostat control and timer
  • Digital LCD display
  • Includes a 2 year warranty
  • We found that it was slightly more noisy than others we've tested

Overall, the FUTURA Eco is an excellent conservatory heater for the money that’s available in several forms to best suit your requirements. The fact that it can be wall-mounted or free-standing is also a great bonus.

5. Best Small: Pro Breeze® Mini Ceramic Fan

(How We Review →)

The Pro Breeze® is possibly the most popular heater on the market and it uses advanced ceramic heating elements that are designed to provide more efficient heating compared to traditional alternatives. Although it’s relatively small when compared to the alternatives, it’s more than powerful to heat most conservatories during the winter.

In terms of the operation of the heater, there is a choice of four modes that include 2 power settings and 2 oscillation settings for evenly distributing the heat in the conservatory.

  • Max output of 2,000 watts
  • Overheat and tip-over protection
  • Lightweight design and portable
  • Choice of 4 operation modes
  • 60 degrees of automatic oscillation
  • Built-in thermostat
  • Only suitable for small conservatories

Heating your conservatory with limited space can be an issue but the Pro Breeze Mini is the perfect solution. It’s able to output evenly distributed heat for warming a range of different-sized conservatories and it also benefits from being relatively affordable, which is always a good bonus when compared to similar-sized heaters.

6. Best Smart: Adax NEO Conservatory Heater

(How We Review →)

Another premium option is the Adax NEO, which is a WiFi-enabled heater with a stylish design that would look great in any conservatory. The brand offers five different models, which include a 600, 800, 1000, 1200 or 1400-watt output.

In order to maximize the space available in your conservatory, it has a low-profile wall projection, which can make a big impact in small conservatories.

  • Multiple heat output models available
  • Available in white or lava grey
  • Low profile design to maximize space
  • WiFi enabled for smart interactivity
  • LCD display with digital thermostat
  • Compliant with all the latest UK standards
  • Includes a 5 year guarantee
  • Paying a premium for the smart features

To conclude, the Adax NEO has a unique design and desirable WiFi connectivity, which may be a requirement for many people. However, the main reason for including it within our roundup is primarily due to the low-profile design.


Conservatory heaters are one of the best investments you’ll make during the cold winter months. Due to the glass construction of conservatories, there is no insulation, which means heat easily escapes and leaves the room feeling cold.

All of our recommendations within our roundup are suitable for heating conservatories and cover a broad range of budgets. If possible, investing in a heater that’s developed by a reputable brand is highly advised.
