Best Pick: Devola Electric Panel Heater

An energy-efficient heater that looks great

The Devola Electric Panel Heater is a slim, elegant design from a company renowned for high-quality products, and with a price tag that certainly will not break the bank.

There is a choice of wattage; 1kW, 1.5kW, 2kW and 2.5kW so it should suit any size of conservatory. In the words of Devola themselves: ‘Complying with new Lot 20 of ERP “Eco Design” Directive, these are the most up to date ENERGY EFFICIENT heaters on the market’. This will undoubtedly help save money on your heating costs.

This unit is very easy to fit to the wall and comes complete with wall mounting kit (H mounting frame + four screws). Just make sure it can be mounted on your conservatory design before buying. Once mounted it is ready to be used.

It has a 7 day, 24/7 timer and the dimensions are 1032 x 116 x 437 mm.

The Devola Heater comes with a 2-year guarantee.

Pros

  • Looks good, slim and elegant
  • Excellent and accurate thermostat
  • Very efficient heating
  • Gives off great heat
  • Very cheap compared to others
  • The 2kw model heats a room up to 22 meters squared

Cons

  • Although the heater is white, customers all complain that the lead is black. You can overcome this by simply painting over the black cable, but beware of invalidating the guarantee by doing this. You could cover it with white insulating tape, available in any hardware store for a small amount. This easily peels off if you have to return the product for any reason.
  • The main complaint of customers is that it is a difficult and long process to set up the timer, while others say ‘it is a bit fiddly, but not too hard’. This programming difficulty can be solved however by switching the unit on and off when needed and not using the timer.

Value Pick: Pro Breeze 2000W Ceramic Heater

Amazing value heater for conservatories

The Pro Breeze 2000W Ceramic Heater is a very handy heater for any conservatory. This fan heater is small, meaning you can place it anywhere; on the floor or even on a table for more direct heat, although this will probably not be necessary.

Do not be fooled by the size of the Pro Breeze Heater; it is very effective and can heat a room to a reasonable temperature in a matter of only minutes. There are two heat settings; 2000W (high) and 1200W (low), and an automatic 60° oscillation mode for larger spaces. There is an adjustable thermostat for optimal heating and energy efficiency.

It has ceramic heating discs that the company claims are faster, safer and more than traditional fan heaters.

The heater is built with advanced safety in mind: a built-in overheat protection and anti-tip-over switch ensure the heater instantly switches off in any unsafe situation. Dimensions are as follows: 18.5 x 15.5 x 26 cm. 220-240V, 50Hz.

Pros

  • Heats up quickly
  • Well-made and solid
  • Energy-efficient and economical to run
  • Heats a room very quickly
  • Very good value for money
  • Can be easily moved around, even put in another room
  • Quiet when running
  • Portable
  • The electric lead is 1.7metres or 67″ from the heater to the plug

Cons

  • No timer, but as it is quick to heat a room, this is not a huge problem
  • Although most customers say this runs quietly, some say there is a little noise
  • A few customers have had problems with the plug burning, but they were reimbursed.

Purus Panel Heater

Wall-mounted or free-standing  – a top product

The Purus Panel Heater is a reasonably priced heater suitable for any conservatory. There is a choice of four wattages; 400W, 1,000W, 1,500W and 2,000W.  To better help you understand what this means in heating terms; the company say a 400W heater will heat a 6 square metre room.

It comes with both fixtures for mounting it on a wall, and feet for leaving it free-standing on the floor, so you can choose which best suits your conservatory.

This heater will not take up much space as it is approximately 45cm long, 8.5cm deep and x 45cm high for the 400W model. The length of the unit changes as you increase the wattage and the 2,000W version is 83cm long.

There is a special function on the Purus Heater which seems to be both a positive and negative. The ‘Auto Open Window Detection’ is an automatic function which, if the heater detects a sudden drop of 5 degrees or more in room temperature, switches itself off to save power. This sounds good, but if you want to open a window for any reason, other than to cool down, your heater will automatically switch itself off. This could be a pain and it would be easy to forget the heater was off until you found the room getting cold.

There is a touch control panel on the front which sits flush. There are four functions; on/off; temperature; heat; and timer. The heat setting allows you to choose between ‘full heat’ or ‘half heat’ – obviously how much this is, depends which wattage machine you bought.

Pros

  • Wall-mounted or free-standing as it comes with both fittings
  • 2-year guarantee
  • An integral precision thermostat which is accurate to within half a degree
  • Easy to operate and programme

Cons

  • The timer can only be used to stipulate how long the heater stays on and cannot be pre-set to turn on at a certain time

Adax Skirting Panel Heater

Sleek and elegant skirting panel heater

The Adax Skirting Panel Heater is a sleek, slimline electric radiator that provides cost-effective heating at an affordable price. The unique selling point of this heater is in its name, and while it is higher than a skirting panel, it will easily fit on the low wall many conservatories have, or any other space you wish to use it.

The Adax Heater has a small, discrete LED display on the front. Many customers recommend using two of the lower wattage heaters in a conservatory rather than a bigger one as they can then be placed at each side, and either used collectively or only the side where you are seated.

The size varies according to the wattage you choose;

  • 600W – Height 20cm; Length 87cm; room size heated 7.5meters square
  • 800W – Height 20cm; Length 105cm; room size heated 10 meters square
  • 1000W – Height 20cm; Length 128cm; room size heated 12.5 meters square
  • 1200W – Height 20cm; Length 145cm; room size heated 15 meters square

The features listed by Adax include; convection heating, LCD temperature display, digital thermostat, 24 hours/7-day timer, open window recognition, adaptive start, child lock (tamper-proof), anti-asthma/allergy, on/off switch, overheating protection, IP20 (not suitable for bathrooms). LOT 20 / ERP Compliant.

Pros

  • Sleek and elegant
  • Easy to programme
  • Easy to install (comes with mounts)
  • Choice of 3 colours, white, black and silver
  • Completely silent
  • 5-year guarantee
  • Cable length: 1.2m

Cons

  • You may need more than one unit for proper heating coverage

MYLEK Electric Over Door Heater

An alternative ‘over door’ form of heating

The MYLEK Electric Over Door Heater is an interesting option for conservatories as it does not have to go on the glass walls, or half wall – if you have one. This sits over the door and heats the room from there. It is approximately 55cm long, 20cm high and 12cm deep, so will easily fit over even a narrow door.

There are no choices of size or wattage, only one model, and this is a white, energy-efficient 2kW modern design. There is an easy to read display on the front, a choice of 1kW or 2 2kW heat settings, and an intelligent thermostat.

There is also a weekly programmable timer, countdown timer with basic timer functions. The MYLEK Heater does more than heat too; it also is a fan to pump out cool air on long, sunny summer days.

The features include; Open Window Detection; Overheat Safety Cut Out; safety cool-down feature; easy to install and it is Lot 20 ERP Compliant.

The MYLEK cable is not very long at approximately 1.5m, which considering this goes over a door and has to reach the floor before being plugged into a socket, is probably not long enough. Adding to, or changing this will probably invalidate the guarantee, so measure the distance you need carefully before buying this unit.

There are quite a few complaints about this heater not working and bad or non-existent customer service, so you might want to weigh that up against the low price before buying. Bear in mind, many customers are extremely happy with this product and find it works well.

Pros

  • Over door unit
  • Remote control
  • Dual hot or cold fan

Cons

  • The cable is not very long
  • The remote control does not always work

How To Keep Your Conservatory Warm In Winter

There are a few obvious things that will keep your conservatory warmer, but they are not all easy or cheap. Here are a few ideas, both as long term investments and quick and economical fixes.

Good Glass and Glazing

The main thing to consider is the glass – this lets in more cold air than a solid wall would. The better the glazing the less heat lost and the less cold is allowed to enter.

If you have single glazing it would be expensive to replace this with double or triple glazing but could end up saving you money in the long run. A cheaper and quicker option to help resolve this problem is conservatory blinds. Again, these are not cheap, but will save you money in the long run.

Heat rises, so even fitting blinds on the roof will help keep your conservatory at a better temperature.

A Quick and Economical Fix…

Check for draughts. You might find little draughts around some windows or the door and this is easy and cheap to fix yourself. Fix any problem areas with putty or draught-excluder which can be bought for a few pounds from any hardware shop.

Although heat rises, a small part of the heat will be lost through the floor. Cold also enters upwards through the floor too, so by adding a rug you help to insulate your conservatory. This can also make your room look more attractive, comfortable and cosy for the winter months.

Heating

Adding a heater is a quick and easy option, and not necessarily an expensive one. The type of heater, size and price are up to you as there are many different models on sale from budget to luxury.
