Your Conservatory Heater Buying Guide

If you are looking for a heating solution for your conservatory, there are many options in the market. To ensure that you find the right one for your home, our quick guide offers you all the essential tips to identify the best heater that you’ll love.

The Size

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

The Type

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.

The Output Power

The higher the output power, the warmer 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-kilowatts.

The Purpose

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. Those with higher effectiveness will help reduce costs on energy bills.


Save yourself hours of frustration and get a heater that is easy to install. There are many of these available, so don’t settle for something that gives you trouble.


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 on already-laid floors.

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.
