FreeHeat SAS, under its trademark Caleosol, engineers, manufactures and sells a complete new set of ecological systems for heating and cooling, using floors, walls and ceilings in order to 
-	reduce the manufacturing cost in CO² from legacy systems with 100 kg of CO²/sqm down to a few kgs or even giving a negative consumption meaning storing CO² instead of producing CO². 
-	reduce the "in service" production of CO² by using agile temperature control systems down to 0.1°c, using geothermal sources to reduce electricity needs and using passive geo-cooling instead of greedy traditional air-con systems
-	eliminate the end of life CO² cost by using circular economy. Each part of the system can be taken apart to be re-used as-is or recycled as a fresh product or used in compost (for the wood fibre part)
-	for industrial use such as spirulina farming, use of fatal heat from the industry or farm methane production. 

For example, a 14 mm parquet flooring can be installed directly without any concrete (which is evil in CO² consumption) on the Caleosol ECO+ which can be as slim as 2cm, including a sound-proof insulation of pure wood fibre. 
This system, far from legacy "all concrete" way, can enable new scenarios:
-	Use of the system for all floors, including wood beam floors, as the weight and thickness is minimal (4kg/sqm and 2 cm thick) 
-	Use of passive geo-cooling (use of cooling from underground without heat pump) due to its frugal design where legacy systems can’t offer this
-	Use of agile temperature control down to 0.1°c as there is no inertia to battle against. Each °c saved accounting for around 8% of heating consumption (ADEME source)

FreeHeat SAS puts a lot of effort into projects to offer its customers the best solutions:
- Software to calculate passive geo-cooling 
- Certification of the use of parquet for cooling and heating with no concrete or glue
- On-going 3 years R&D project on future geo-cooling systems with main French stake holders
