Heaters for Your Conservatory Buying Guide

If you are looking for a heating solution for your conservatory, there are many options in the market. They range from baseboard heaters to oil filled radiatorsplinth heaters and electric log burners. A fan heater could also heat the space while a wireless thermostat provides you with control from whichever location.

There are important factors you should put into consideration when choosing the best conservatory heater. And we will guide you through each one of them. We will show you how to select the best device.

The Size

Larger units are more potent than smaller ones and are therefore most suited for more wide spaces. They also tend to take upa little bit more room and are bulkier. Smaller ones, though not as powerful, can easily be positioned inconspicuously. They’re much easier to move around if you plan on continually changing the position.

However, smaller models are the best way to heat a conservatory with smaller space. It is usually advised to use two smaller sized heaters positioned in opposition than one large heater. The latter tends to make one part of the conservatory hotter than the other.

The Type

Heaters for Your Conservatory Buying Guide

Generally, there are three basic types you can choose from;

  • Radiators– which are powered by electricity. They produce heat by heating an element, either water, oil or some other substance.

  • Convection Heaters– which channel air currents through the heater into the room.

  • Fan Heaters– which blow air across a heating element, directing the heat produced towards the room.

While each one is unique in its way, they all have pros and cons you need to consider. Radiators are of varying sizes but are all very good at keeping the heat constant. Most electric radiators have the advantage of being programmable. Oil-filled radiators are more massive than their water counterparts but are usually more efficient.

Fan heaters are ideal for quick, direct delivery of heat. They are also the cheapest way to heat a conservatory, but this is lost once the appliance is turned off. Convector heaters are very silent but take a longer time to heat the room. However, they are great for even distribution of heat.

The Output Power

The higher the output power, the more influential the heater. A 0.6KW heater or mini heater is suitable in a small conservatory or one that needs supplementary heating. However, if your space is vast, go for a model at the range of 1.5KW to 2 kilo watts. The output power still depends on the effectiveness of the heater, as some, though powerful, is very wasteful.

The Purpose of Use

Any type of heater would be ideal for your conservatory if you only need periodic heat temperature boosts. However, if you wish to maintain a specific temperature range, get one with a timer. Models with a frost protection setting make sure your conservatory temperature never falls below 0°C. For long periods of use, you should get a model with an adjustable thermostat as they’re more energy efficient. These models also offer you more flexibility and control.

The Energy Efficiency Level

Some heaters are more energy efficient than others and as such, must be analyzed. Those with higher effectiveness will help reduce costs on energy bills. Usually, radiant and convection heaters are very efficient. The former uses less power, though they run best in a smaller room. The latter, however, can perform with utmost effectiveness, especially when they don’t use a fan for circulation. Most times, energy efficient heater is hinted on the package. The Eco type heater and the radiator offer this function.

The Mode of Setup and Installation

Heaters for Your Conservatory Buying Guide

Our advice – you also need to consider the ease of setup. The instructions for installation should not be complicated. Also, if you’re considering how much space the heater will take, purchase wall mounted units.

Freestanding units are also high but not advisable if you have children or pets around. Also, consider if there’s a child lock to prevent tamper with the settings from your kids. Ease of use is also essential.

Models with fewer functions tend to be very user-friendly. Others come with remote so that you can access your preferred temperature with ease from a distance.

The Cost

In the end, the number one factor that usually determines what you go home with is the price. Generally, most high-quality units, i.e. panel and wall heaters, are very costly. Other models with moderate prices often offer excellent quality as well. Also, some mini heater which offers at least half the same type of top-quality as their larger, more expensive counterparts. However, the high price doesn’t always mean high-quality performance. So, always look out for the earlier features before considering the price.

Understanding the Jargons

IP – International Protection code rating degrees of protection for the intrusion of dust, water, etc.

BEAB – British Electrochemical Approvals Board

Intertek – a multinational assurance inspection, product testing and certification body

Lot 20 – A legislative standard in the EU which compels all local space heaters to comply with a set of minimum effectiveness standard.

What are the Different Features?

To most users purchasing conservatory heaters, there are certain features they tend to look out for. These features though different from person to person, usually determine the appeal of these units to users. However, a significant feature most user consider interesting is the design. Many users look out for this because, above all else, they want a heater that blends aesthetically with their conservatory.

Also, users tend to consider energy-efficiency because above all else; they want a heater that won’t rake in massive energy bills. For this reason, they tend to go for Eco-friendly heaters that promise high levels of effectiveness.

Heaters for Your Conservatory Buying FAQs

Q: Do I need planning permission for a conservatory with the radiator?

A: Not necessarily. Conservatories are usually independently heated and as such are free from building regulations. However, if you’re planning to connect the radiator to the central heating system that supplies the main building, then your plan will be subject to building regulations.

Q: How to heat a conservatory?

A: You can employ electric heaters for quick and easy heat delivery. You can also use trench heating, though those can be expensive. There’s also conservatory underfloor heating, which is usually hard to regulate and even harder to set up in already-laid floors. Another option is using a low-level column radiator which can take less space but supply high heat. Then there’s connecting your conservatory to the conventional building radiator and gas central heating. This would require building regulations approval.

Q: What is the best way to heat a conservatory in winter?

A: Programmable units are the best options for the winter. You can set up a constant temperature preference that will be set for some time, usually a day or a week.

Q: Why can I not install a radiator in a conservatory?

A: Radiators are very energy wasteful. They swirl warm air up the roof instead of evenly distributing the heat, leaving you cold at ankle level. They are not ideal for conservatories.
