What Temperature Should I Set My Thermostat?

The ideal thermostat temperature is one that everyone in your household finds comfortable. Typically, this falls between 21°C and 27°C. However, the exact setting will depend on how often the room is used and for what purpose.

As a general guideline, it’s recommended to set your underfloor heating manifold between 35°C and 45°C. This range can generate a comfortable ambient temperature of up to 25°C. Keep in mind that your floor coverings play a crucial role in how efficiently heat is distributed:

• Good Conductors: Materials like concrete, slate, terracotta, ceramic, and porcelain emit heat quickly and can be heated up to 29°C.
• Poor Conductors: Wood, laminate, carpet, and vinyl should not be heated above 27°C due to limited heat transfer.

Room size and insulation also influence your thermostat settings. Smaller rooms heat faster, and spaces with double-glazed windows and draught-proofed doors retain heat more effectively.

Ideal Thermostat Temperature for Summer

During summer, the ideal thermostat temperature for underfloor heating is between 17°C and 20°C. Many people choose to turn off their underfloor heating completely during warmer months. However, if you have a wet underfloor heating system, it’s recommended to run it for 15-20 minutes every two weeks to prevent the system from sticking.

For those who feel the cold, such as elderly family members, keeping the heating on a low setting during cooler summer evenings may be more comfortable. Ultimately, the ideal temperature depends on what your household finds comfortable.

Ideal Thermostat Temperature for Winter

In winter, setting your thermostat between 21°C and 25°C is generally sufficient for most living rooms and lounges. Bedrooms and less frequently used areas, such as bathrooms or kitchens, can be set slightly lower at around 18°C. Personal preferences, insulation, and energy costs should also be taken into consideration.

Proper insulation—including wall, loft, and cavity insulation—ensures you get the most out of your heating system, reducing energy waste and saving you money.

Ideal Temperatures for Different Rooms

For maximum efficiency, consider using individual thermostats for each room or zone in your home. This allows you to customize settings based on usage:

• Living Room: Start with 21°C and adjust as needed.
• Bedrooms: Set to around 18°C for a comfortable sleeping environment.
• Kitchens and Bathrooms: Initial settings at 18°C work well, but you can adjust based on personal preference.

Smart thermostats make this even easier by allowing you to program specific temperatures and times for different areas of your home.

How to Save Money and Energy with a Thermostat

Saving energy and money with underfloor heating starts with setting your thermostat correctly and ensuring your property is well-insulated. Here’s how you can maximize efficiency:

• Program Your Thermostat: Use a smart thermostat to control heating times and temperatures for each room.
• Insulate Your Home: Poor insulation can increase heating costs by up to 30%. Ensure your walls, windows, and doors are well-insulated.
• Set Efficient Temperatures: Stick to recommended ranges (21°C-27°C) to balance comfort and cost.

By following these steps, you can enjoy the comfort of underfloor heating while minimizing your energy bills. If you’re interested in upgrading your thermostats or learning more, explore our range of options tailored to suit every home.
