Conservatories can be beautiful additions to a home, but heating them comfortably can be challenging. Large windows and glazed roofs can make conservatories feel cold during winter while allowing temperatures to rise quickly during warmer weather. So, when it comes to heating a conservatory, should you choose underfloor heating or radiators?
Both options have their advantages, but underfloor heating can offer several benefits that make it particularly attractive for conservatories and extensions.
Why Can Conservatories Be Difficult to Heat?
The large amount of glazing found in many conservatories can increase heat loss during colder weather. This means the heating system needs to work effectively to maintain a comfortable temperature. Insulation is therefore extremely important. Before choosing a heating system, consider the:
- Floor
- Walls
- Roof
- Windows
- Doors
- Overall construction
Improving the building's insulation can make a significant difference to heating performance.
Underfloor Heating in a Conservatory
Underfloor heating turns the floor into a large heating surface. Instead of concentrating heat in one area, warmth is distributed across the usable floor. This can create a comfortable environment without taking up wall space. Electric underfloor heating can be particularly practical for conservatories and smaller extensions.
Radiators in a Conservatory
Radiators are a familiar heating solution and can provide a strong source of heat. However, they need wall space. In a conservatory with large areas of glass, available wall space may already be limited. Radiators can also create areas of concentrated heat rather than distributing warmth evenly across the floor.
Which Is More Comfortable?
Underfloor heating has a major comfort advantage: warm flooring. This can be particularly noticeable in a conservatory where tiled or stone flooring can otherwise feel cold during winter. The heat is distributed across the floor, helping create a more consistent temperature throughout the space.
Electric Underfloor Heating for Conservatories
Electric systems are often a convenient option for conservatory projects. Fastwarm offers a 200W/m² electric heating mat system specifically intended for areas with higher heat loss, including conservatories and extensions. The system is designed to provide greater heat output than its 150W/m² option, making it worth considering where additional heating output is required.
However, the heating requirement should always be assessed based on the specific room.
Does Underfloor Heating Take Up Space?
No. One of the biggest advantages of underfloor heating is that the system is hidden beneath the floor. This means you can use your wall space for:
- Furniture
- Storage
- Shelving
- Windows
- Doors
There is no radiator taking up valuable space.
What Flooring Works Best?
Tiles and stone are particularly popular in conservatories because they transfer heat effectively. LVT, laminate and suitable engineered wood can also work with underfloor heating. Always check the flooring manufacturer's instructions before installation.
What About Insulation?
Insulation is particularly important in conservatories. The better insulated the room, the easier it will be to maintain a comfortable temperature. Suitable underfloor heating insulation can reduce heat loss through the floor and help direct warmth upwards. However, floor insulation should be considered alongside the overall insulation of the conservatory.
Which Is Cheaper to Run?
There isn't one answer for every conservatory. Running costs depend on:
- Size
- Insulation
- Heat loss
- Heating output
- Energy tariff
- Thermostat settings
- How often the room is used
The most important thing is choosing a correctly sized system rather than simply selecting the cheapest installation.
Can Underfloor Heating Replace a Radiator?
In some conservatories, yes. However, the system needs to be designed to meet the room's heat requirements. If the conservatory has significant heat loss, additional heating may be required. A professional design can help determine whether underfloor heating alone is sufficient.
Underfloor heating can be an excellent choice for conservatories and extensions. It provides warmth without using valuable wall space, works particularly well with tiled floors and can create a more comfortable environment underfoot. Fastwarm offers electric systems designed for different applications, including higher-output options for conservatories and extensions.
