How to Heat a Conservatory

How to heat your conservatory

Investing in a conservatory that you can only sit in during the summer is very in practical and something that many people experience. These heating methods below will allow you to enjoy your conservatory all-year round and keep you warm during winter.

The 3 main conservatory heating methods

Underfloor heating 

There are two types of these systems, water-based and electric.Water based connect underfloor pipes in the conservatory to the boiler and circulate warm water. Electric systems use a series of electric heating sheets that are connected to the electric supply.

Under-floor heating


✔️ This method can be the most efficient, if the conservatory is used frequently.

✔️ Silent and invisible, it doesn’t take up any space so it’s perfect for small conservatories with limited capacity.

✔️ Child-friendly, there is no danger of kids touching hot surfaces.


❌ Unsuitable for conservatories used spontaneously as it can take a long time to heat up and cool down.

❌ Installation is quite expensive. Installation is much easier for conservatories built from scratch, instead of pre-existing ones.

❌ Be careful what furniture you place on the floor, you may have to place some items on insulation.

NOTE: Best floors for underfloor heating:

The ideal floors for underfloor heating are tiles and stone, as these materials have high thermal conductivity. Vinyl materials are also a good option to use, as they can heat up and cool down quickly.

Other materials that can be used: Wood – engineered timber and solid timber flooring. Carpet – however be aware, a tog rating higher than 1.5 will make it harder for heat to penetrate the floor.

Central heating

It is possible to extend your current central heating into the conservatory so long as it is controlled separately with its own power switch. It is important to consider the demands of heating the conservatory in order to ensure your current boiler has the power to heat another room.

White Radiator


✔️ Installing central heating is a quick and cost-effective solution.

✔️ Radiators now come in a range of styles that can fit in small spaces, like vertical models which can fit under window-sills.


❌ There is a possibility that your boiler will need to be upgraded in order to have power to heat another room.

❌ Wall space can be limited; this can be a problem for small conservatories.

All year round conservatories

Standalone electric heaters

This is the easiest method as it requires no installation or piping. This is useful if you either can’t or don’t want to extend your current central heating. This method can be more expensive; however, it can heat up rooms faster.

Electric radiator


✔️ This is the most flexible heating solution for your conservatory.

✔️ Helpful for space-constrained conservatories.

✔️ They can heat up small spaces very quickly.


❌ Electric heaters can use up a lot of energy and be expensive to run.

❌ They are in-effective at heating up large spaces in a house.

Important Considerations – 

Before you decide how to heat your conservatory, you should ask yourself these questions.

  • How frequently will the conservatory be used? – If you use your conservatory through-out the year, including Winter, then central heating may be the best choice. Where-as if you use it infrequently then the ideal option is an electric heater.
  • How large is the space you want to heat? – If you’ve got a small space, electric radiators are very effective, because heat cannot escape as easily.
  • How much are you willing to invest? – If your conservatory is a main feature of the house that you use regularly, then investing in central heating could be a better choice. However, the option of heating also comes down to personal preference and it’s also about weighing up the trades offs of each method.
  • Do you know about building regulations? – Building regulations state that any heating mechanism in a conservatory must be separate from the main house’s method of heating. This is because conservatories are comparatively poor at insulating and can significantly reduce the energy efficiency of the home.
