What are the best low-energy heating solutions for a UK conservatory?

As homeowners, you understand that conservatories are great additions to your homes, offering extra living space and a place to enjoy the surrounding landscape. But, as winter months approach, the challenge of maintaining a comfortable temperature in the conservatory arises. With this in mind, we are going to discuss the best low-energy heating solutions for your conservatory, focusing on key factors such as efficiency, cost, and how well they can heat your conservatory. We will delve into options such as electric radiators, underfloor heating systems, and space heaters.

Electric Radiators

Let’s start with electric radiators. These can be an effective and energy-efficient solution for heating your conservatory. You might ask, "Why electric?" The answer is in their design and operation.

Electric radiators work by converting electricity into heat. As electricity passes through the radiator, it heats up a thermal fluid inside which then emits heat around the room. This process is 100% efficient, meaning that all the electricity consumed is transformed into heat.

Your conservatory will benefit from this system because of its ability to provide a steady, consistent temperature. Electric radiators also offer complete control over heat settings, allowing you to adjust the temperature to your liking.

Regarding costs, electric radiators have a lower upfront cost compared to other heating systems. However, bear in mind that the running cost will depend on your energy supplier’s rates and the amount of time you use the radiator.

Underfloor Heating Systems

Next, we have underfloor heating systems. They’re becoming increasingly popular due to their high energy efficiency and the comfortable warmth they provide.

Underfloor heating works by circulating warm water through pipes or using electric heating cables installed beneath the floor. This creates a large heated surface that effectively warms up the room. One great advantage is the even distribution of heat, avoiding the cold spots that can occur with other heating methods.

In terms of energy efficiency, underfloor heating systems are at the top of the list. They operate at lower temperatures than traditional radiators, which reduces energy consumption. This is an important point to consider when thinking about the energy bills.

Cost-wise, underfloor heating systems can be more expensive to install compared to other heating solutions, but the ongoing running costs are significantly lower. This makes it a cost-effective solution in the long run.

Space Heaters

Space heaters are a simple and versatile heating solution for your conservatory. They’re portable, easy to use, and can provide immediate warmth to a specific area.

The way space heaters work is straightforward. They use a heating element which, when powered on, starts to generate heat. This heat is then distributed either by a fan or by natural convection.

In terms of energy efficiency, the outcome will depend on the type of space heater you choose. For instance, infrared heaters are known to be extremely efficient as they heat objects and people directly rather than the air.

The cost is another plus for space heaters. They are generally affordable to buy and run, but remember that the total cost will depend on how often you use the heater and your energy tariffs.

Room-specific Heating Solutions

Lastly, room-specific heating solutions can be a good idea for conservatories. These are systems designed to heat a single room instead of the whole house, and they can provide a more efficient use of energy.

One example is a split-air system, where a unit is installed in the conservatory and connected to a compressor on the outside. It can provide both heating and cooling, making it ideal for year-round use. Another example is a pellet stove, which burns compressed wood or biomass pellets to create heat.

In terms of costs, room-specific solutions can vary widely based on the system you choose. However, they can represent significant savings in terms of energy bills, as they avoid the waste of heating unused areas of your home.

Central Heating Systems

Another excellent low-energy heating solution for your conservatory is a central heating system. This is typically powered by a boiler, which can be fuelled by gas, oil, or even wood pellets.

The way a central heating system works is by heating water in a boiler, then circulating the heated water through pipes to radiators located throughout the house. When the water reaches the radiators, it transfers its heat to the air, raising the room’s temperature.

For conservatories, a radiator connected to the central heating system can be installed to keep the space warm. As radiators are designed to provide even heat distribution, there won’t be any cold spots in the room. Plus, since the system uses the same energy source to heat the entire house, it can be a highly energy-efficient option.

As far as costs are concerned, central heating systems have a higher initial installation cost compared to individual heaters. However, the running costs can be lower, especially if your home is already equipped with a central heating system. Integrating your conservatory into the existing system can be a cost-effective way to heat it year-round.

Insulation and Curtains

Besides heating systems, you can also improve energy efficiency in your conservatory by using insulation and curtains. Having a well-insulated conservatory reduces the amount of heat that escapes and will make your heating system more effective, reducing running costs in the process.

Insulation can be applied to the roof, walls, and floor of your conservatory. For example, you can use insulated plasterboard for the walls and thermal floorboards for the floor. The roof can be insulated using a range of materials, from reflective foil to rigid foam boards.

Curtains, blinds, or shutters can also be used to trap heat in the conservatory, especially during the night or in colder months. Thermal curtains or blinds can be especially effective, as they are designed to retain heat and prevent draughts.

Remember, while the initial cost of installing insulation and curtains can be high, the energy savings in the long run make this a worthwhile investment.


Choosing the right heating solution for your conservatory is crucial for maintaining a comfortable temperature year-round, without causing a surge in your energy bills. From electric radiators to underfloor heating, central heating, and even room-specific solutions, there are plenty of low-energy heating options to consider.

It’s vital to consider the size of your conservatory, your budget, and how often you use the space when deciding on the most appropriate heating system. Additionally, improving insulation and using curtains can significantly increase the efficiency of your heating solution, further decreasing running costs.

By implementing the right combination of these solutions, you can create a cosy, energy-efficient conservatory that you and your family can enjoy throughout the year—no matter the weather.
