A COMAP thermostatic head is installed on a thermostat body. It is necessary to make sure the assembly is fitted correctly and is functioning. COMAP thermostatic bodies and heads are all compatible with one another. In addition, Keymark (EN215) standard compliance and Comap heads' energy efficiency guarantee the quality and efficiency of the Comap thermostatic solution.
The figures for COMAP heads are available from the Certita certification organisation : http://www.certita.fr/marque-certita/variation-temporelle-des-robinets-thermostatiques
